PostHeaderIcon How Does A Car Engine Work?

Russell Shortt asked:


First things first, the car engine is an internal combustion engine, of which there are a number of different types, including the diesel engine, petrol engine, rotary engine and two-stroke engine. The internal combustion engine runs on the basic premise of injecting a tiny amount of high energy fuel, for example petrol or diesel, in a small enclosed space, igniting it and creating a massive amount of energy in the form of an expanding gas. The trick the internal combustion engine pulls off is setting off explosions like this hundreds of times over a minute and managing to harness the energy that is thus created. Almost all cars use a four stroke combustion cycle to convert petrol into motion, the four strokes being – intake, compression, combustion and exhaust. At the beginning of the cycle, the piston starts at the top, once the intake valve opens, the piston moves down, letting the engine take in a cylinder full of air into which is also injected a drop of petrol. The piston then moves back up to compress the air with the drop of petrol, the compression will make the explosion that is about to occur all the more powerful. When the piston reaches it’s limit, the spark plug emits a spark which ignites the petrol, causing an explosion thus driving the piston back down. When the piston it reaches it’s bottom limit, the exhaust valve opens and the exhaust leaves the cylinder, leaving the vehicle by the tailpipe. This cycle is then repeated over and over again. The linear motion of the pistons is converted into a rotational motion by the crankshaft which subsequently turns the vehicle’s wheels. So as you may have gathered, the cylinder is one of the core components of the internal combustion engine. Most cars have four, six or eight cylinders.

PostHeaderIcon Car Wheels

Kalin asked:


To understand on the best possible way what are car wheels all about and why they are usually the first thing to go when talking about upgrade let’s see some information on a research that took place on 1990.

That research was done after the brake down of the wheels on some cars during race. The wheels were heated and this thermal energy could usually result in aging of the material. We talk about aging when the material is in conditions that greatly reduce its normal life.

There is a whole branch of science that is called “material resistance” and it’s about how materials can be made to sustain a long life with minimal resources. This science analyzes the stress caused by various reasons.

Researchers found residual stress that was held in the wheels. When wheels are manufactured the material is processed on many ways. The annealing, forming and some other techniques leave the material in internal stress. This makes it vulnerable and after sufficient load a thermal cracks will appear and after that the material will most likely damage. This could quickly lead to its complete destruction.

When we say residual stress we refer to all the stress that remains after the object is processed and then freed of all load.

After some further discoveries scientists found that the cracking was done by fatigue of the material. It was a result of the fraction that was caused by the brakes. The thermal cracks were found on the axis of the wheel.

The real material resistance plan is about calculating both residual stress made during manufacturing and the stress caused during the service of the wheel. The second one could be done by setting math variables in proper formulas to watch for how the material is damaged during the process. This will help us pick the right material for the time that we need to have before the product become unusable.

To see how we can control the residual stress we have to understand the manufacturing process in depth.

To make the wheels in the proper shape a multi-step process is used. This is about making the inceptive form of the product. Then the residual stress has to be released. This happens when a high temperature is applied. When we do that the particles of the material begin to move more quickly and reorganize in a better way. Usually the temperature that is used is around 871 °C. After the part is reheated it is cooled with a water spray. This helps to gain the proper microstructure of the material.

For conclusion about the research we have to point that after it there is a way for simulation of service and checking how the wheels will respond then it is easy for experiments to be made and better products that will endure more and cracks will be not likely to appear.

One criterion of the wheels is its size. Simple mechanics can tell you that its one of the most important things about wheels because the size is linked to the speed. Imagine a bicycle with small wheels and then with big one. The one with the bigger wheels will move more quickly because one turnover of the wheels will pass a greater distance. It’s the same with cars.

When picking wheels you have to know that different cars have different suspension and you have to insure that the wheels are good for your car. You can see the specification of the wheels to secure yourself from a mistake. In Auto direct save you can see different wheels with different sizes and this will surely help you with your choice. The wheels are the component of the car that interact with the road and let it move so you have to be very careful when picking them.


PostHeaderIcon Hybrid Car Prices: Good Value For The Money

Ernest Jarquio asked:


Retail hybrid car prices as suggested by manufacturers (better known as MSRP) are decided by the car makers and advised to the car dealers to be the base price guide in dealing with public sale. Dealers providing fleet sales to corporate buyers have also the invoice price, or that amount paid by the dealers to the automakers, better used for wholesale purchases being made from the dealers.

While these two serve as guides for the car buyer, prices may increase due to additional costs for non-standard features or add-ons to the vehicles. There are also charges for delivery to move the vehicles to the final destination where buyer is situated. Thereafter, sales taxes, marketing costs, registration costs and other costs may be added by the dealership over and above the MSRP or invoice price.

Price Ranges

As of this writing, at the bottom rung is the Toyota Prius, most reasonably priced at suggested retail of $22,175, exclusive of tax incentives that come along with purchases of hybrid, environmentally-friendly units. At the high end of the spectrum will be the 2007 Honda Accord Hybrid 4-wheel drive four-door sedan, at around $31,000. Both these prices do not include delivery or destination pricing.

The Array of Hybrid Car Prices

In between the Prius and the Accord, the Camry Hybrid from Toyota is priced at around $26,000. The Saturn Aura Green Line Hybrid starts at $22,695, a highly recommended purchase by many hybrid enthusiasts. The Honda Hybrid FWD four door sedan starts at $22,600 exclusive of destination costs.

To give you a gauge on SUVs, the Mercury Mariner 2008 Hybrid four-wheel drive SUV starts at the bottom with $27,515, followed by the Ford Escape Hybrid 4FD SUV at $27.250. Packed and loaded with all amenities you can ask for, the 2007 Toyota Highlander Hybrid can be yours for $32,500.

Price Indicators

The brand name comes with the package. With such prestigious car makers as Toyota, Honda, Ford, Saturn, Mercury, Volkswagen, Mercedes, the name comes at a premium. Brand name notwithstanding, the full array of features and accessories not included in standard units also impact on the final price of the hybrid car you are purchasing.

Hybrid car prices are definitely higher than for conventional models. That’s because the manufacturer requires more resources to produce the hybrids with their added valuable features – these all add up to the cost. It is envisioned, though, that the fuel savings from hybrids will more than compensate for the usually higher purchase price compared to pure fossil-fuel models.

To give you an idea, take the Honda Accord as an example. While a value-packaged 4-door Accord Sedan can fetch for as low as $19,450, the Hybrid Accord’s price is almost twice higher at more than $31,000. While Accord’s special edition sedans and coupes range from $23,350 to $23,450, these prices are still a far cry from hybrid’s prices. Only the EX-L four-wheel drive 2-door Accord Coupe comes close at $27,500.

The price differences among Civic models are somewhat more manageable and saleable. Take a 4-door sedan Civic EX priced at $19,510 add a hybrid system and you’re $22,500 poorer. But the price difference, at least, is not all that much.

Even with Toyota models, the fuel efficiency and environmental-friendliness and zero-emission tags all come at a premium. The Camry Hybrid starts at $25,200 when its conventional sister is priced at only $18,570. Even with the federal tax reductions for hybrid vehicles, the MSRP is still a tad higher.

With the kind of research and development, not to mention the extensive testing done on hybrid or alternative-fuel models, it’s not surprising that hybrid car prices are more expensive. And manufacturers do not stop at the hybrid or fuel-efficiency features; they also try and pack the hybrid with the latest in electronics for the interiors, dash and instrumentation and everything.

Standard or optional amenities notwithstanding, environmentalists will always say that hybrid car prices are worth every penny car buyers shed, if only to ensure a better, cleaner, safer world for tomorrow. Amen to that, say the hybrid manufacturers’ environmental drum beaters.

People under the twenty five years who would love to obtain a car know how problematic and tough it is to get insurance rather than a four wheeler these days.These days obtaining cost-efficient and cheap car insurance for young drivers is hard . As it is the teenage drivers are thought to run a risk due to lack of driving experience and not being as reliable as the older experienced generation. The CDC (Centers for disease control and prevention) avers that one in three accidents is caused by the fault of teenagers, which for sure adds anxiety to the parents of teenagers.

Statistical surveys like the above and their prior experiences have made the vehicle insurance firms to charge a steeper rate of insurance premiums for the young drivers. The automobile insurance for young drivers might even be different from one person to another also .This can be due to certain factors like your home location, your former driving record, your *** or the type of vehicle you drive (whether it is a safe automobile or not) .The amount of young driver sedan insurance premium is shifting from not only from one firm to another but also on an individual basis and taking these aspects into consideration one should look for cheap car insurance for young drivers.

It is indeed feasible to lessen the premium charges of your young driver. How? By furnishing some important information and then negotiating with the insurance provider based on the same. First of all if the everyday distance travelled is lesser then there is lower risk so it might lessen the automobile insurance for young driver. Secondly if the car is higher ended in safety features like a four door sedan with alarm system, anti-lock breaks, low mileage etc it will further decrease the premium. Thirdly if the previous driving record is without…Read More


PostHeaderIcon Want a Hybrid Car? Better Compare Them Here First

Floyd Dorrance asked:


Compare ALL Hybrid cars with each other before deciding.

The following article includes pertinent information that may cause you to reconsider what you thought you understood. The most important thing is to study with an open mind and be willing to revise your understanding if necessary.

For the past fout or five years, there has been much ado about Hybrid Cars and the many benefits they could offer. Their popularity has been compounded by the ever surging gas prices and the concern for the environment. It seems that Hybrid Cars are the solution to both. When you use a Hybrid car, you contribute less to the thickening air pollution, plus you save a lot of money since they require less fuel, plus there are numerous tax credits being given by many states.

For these reasons, hybrid cars have experienced a sharp increase in sales and more car manufacturers are joining the hybrid vehicle arena with their own versions. For those who are planning to buy a hybrid car, the choices are numerous, that’s why you have to compare hybrid cars with one another to see which one would go well with your needs.

Two of the top hybrid car manufacturers are the Japanese giant’s Toyota and Honda. They are credited with producing many innovations in the hybrid technology and their hybrid cars are the most acclaimed, most sought after and most awarded hybrid vehicles today.

Here we will compare the hybrid cars they are offering for 2007, these will include the Honda Accord Hybrid, Honda Civic Hybrid, Lexus GS 450H, Toyota Camry Hybrid and the Toyota Prius.

You can see that there’s practical value in learning more about “hybrid car”. Can you think of ways to apply what’s been covered so far?

Their fuel efficiency can be compared through their average consumption per mile in different situations, like; City Driving – where the traffic is constantly stopping, Highway Driving – where the engine can freely operate at maximum level and their combined average usage.

Miles Per Gallon – Average Miles Used Per gallon of Fuel

· Honda Accord Hybrid – 28 MPG (city), 35 MPG (Highway) and 31 MPG (Combined Average)

· Honda Civic – 49 MPG (city), 51 MPG (Highway) and 50 MPG (Combined Average)

· Lexus GS 450H – 25 MPG (city), 28 MPG (Highway) and 26 MPG (Combined Average)

· Toyota Camry Hybrid – 38 MPG (city), 40 MPG (Highway) and 39 MPG (Combined Average)

· Toyota Prius – 51 MPG (city), 60 MPG (Highway) and 55 MPG (Combined Average)

But before you just pick out the one with the highest MPG average, you still have to consider and compare a couple of aspects as well. This includes the fuel type. All of these vehicles use regular gasoline except for the Lexus which uses Premium Gasoline that is pricier.

Then you also have to compare the size class of each hybrid car and their engine size and liters. The Accord Hybrid is a midsize car with a 3 liter – 6 cylinder engine. The Civic Hybrid is a compact car with a 1.3 liter – 4 cylinder engine. The Lexus is another compact car with a 3.5 liter – 6 cylinder engine. The Camry Hybrid is a midsize sedan equipped with a 2.4 liter – 4 cylinder engine and the Toyota Prius is a compact car with a 1.5 liter – 4 cylinder engine. The more powerful the engine is, the more fuel will be consumed.

Considering this aspect and others is needed when comparing hybrid cars. You have to consider the differences. Before purchasing a hybrid car, compare first and do your research. Find one that would suit your needs and your personality best to get the perfect hybrid car for you.

That’s how things stand right now. Keep in mind that any subject can change over time, so be sure you keep up with the latest news.


PostHeaderIcon Car Engine Modifications

Carazoo.com asked:


Car engine is believed to be the heart of a car. Today, with the increasing numbers of cars, Indian car market also comprises a variety of engines with unique specifications and characteristics. These car engines can be modified or altered to boost engine performance and enhance fuel efficiency.

Here are some of the best tips on car engine modifications:

• The best way to get better power and performance from the car engine is to increase engine displacement. This can effectively be done by increasing the size of the cylinders or by adding more numbers of cylinders to the equipped engine.

• Increase the engine’s compression ratio by fueling the engine by higher octane gasolines. This kind of gasoline helps to compress the fuel mixture and results in early combustion, which thereby produces more power.

• Fix in an intercooler so that the compressed air gets cool before it’s enter the engine’s cylinder. This will help in expansion of air during combustion, delivering more power and performance.

• Improve air flow to the cylinder and out of the cylinder because air resistance can reduce power. The air intake as well as exhaust should not be influenced by any kind of resistance. This can be done by placing two intake valves and exhaust valves in the cylinder. The intake flow can also be improved by adding big air filters to the engine and the exhaust can be improved by adding big exhaust pipes and flowing mufflers.

• Replace heavy components and parts of the engine. Lighter the engine components better is the engine performance. Every time when the piston moves to change its direction it uses the energy from the engine and eventually reduces the power. In such a case, a lighter weight piston will be beneficial as it will absorb less power.

• Fuel injection helps to precise metering of fuel to each of the engine’s cylinder. This helps to boost performance and improve fuel efficiency.

• Optimize the timings of the valve to have better burning efficiency. This will improve production of power and can be done by modifying the camshaft.

• Chip tuning also helps in delivering more power. Most of the new cars are loaded with advanced engine that deliver higher power. Chip tuning in association with the engine management system reduces the excessive power to make the engine operate smoothly and with better performance. This is also known as de-tuning.


PostHeaderIcon Are Bigger Car Wheels Better?

Vikram kuamr asked:


One question that is commonly asked by many car owners is whether bigger car wheels are truly better than smaller sized ones. In a world where technology has broken down a great many boundaries, it is often said of many things that size does not matter. There are, however, still some situations in which size does matter. In fact, in the case of car wheels, size makes a great deal of difference.

 

It is easy to dismiss big car wheels as simply being a fancy of street racers and young punks attempting to look ‘cool’. Of course, this is definitely true. The younger generation posing on the streets are hardly concerned with the handling and comfort that bigger wheels provide so much as they are concerned with the boost to their image that such wheels give. Nevertheless, this is far from the only use that large car wheels have.

 

Any experienced driver should be able to tell you that larger car wheels do, in fact, improve the safety and handling of your car. One of the most important things when driving your car is how well it handles. Handling determines how well your car responds when you turn the steering wheel, and whether it will go where you want it to or veer off in another direction because the car wheels are unable to grip the road surface properly. Handling is most important when traveling at high speeds because you might need to react quickly in the event of an emergency, and without proper handling, you might not be able to turn your car in the direction that you need to go fast enough.

 

Another aspect in which having larger wheels definitely helps is when it comes to braking and stopping. The length of time it takes for your car to come to a complete stop is dependent on the amount of friction present between your car wheels and the surface of the road. Having larger car wheels will provide a greater area of contact between your wheels and the surface of the road, thus allowing your car to slow and come to a complete stop more quickly than with smaller wheels. This is particularly important if you have to stop to prevent from hitting an obstacle or to avoid an accident.

 

Finally, larger wheels also provide for a smoother and more comfortable ride than smaller wheels. This is because larger wheels are not as prone to falling into depressions in the road, and they simply ride over bumps that smaller wheels would take more effort to get over. If you find yourself in your car often or you have to travel long distances to and from work on a regular basis, then the degree of comfort offered by your car while on the road is definitely something important to you. With larger wheels on your car, you would be able to cruise over potholes and other imperfections in the road while cars with smaller wheels would be bumping up and down, jolting their drivers to no end.

 

Thus, when it comes to car wheels, size does indeed matter, and the you would do well to purchase larger car wheels for your car, so as to improve the overall comfort, handling, and performance of your vehicle.
