How do car engines work? - Explain that Stuff

Continuance of the use of the internal combustion engine for automobiles is partly due to the improvement of engine control systems (onboard computers providing engine management processes, and electronically controlled fuel injection). Forced air induction by turbocharging and supercharging have increased power outputs and engine efficiencies. Similar changes have been applied to smaller diesel engines giving them almost the same power characteristics as petrol engines. This is especially evident with the popularity of smaller diesel engine propelled cars in Europe. Larger diesel engines are still often used in trucks and heavy machinery, although they require special machining not available in most factories. Diesel engines produce lower and CO2 emissions, but greater and pollution, than gasoline engines. Diesel engines are also 40% more fuel efficient than comparable gasoline engines.

It is—by a long shot. The engine requires less than half the parts of a similar four-stroke engine and is 30 percent lighter. The net result, says Hofbauer, is a 15 to 50 percent increase in energy efficiency, depending on the configuration. And thanks to its unique architecture and several key innovations, the OPOC releases far fewer emissions than a typical two-stroke. With a 240-hp diesel prototype, EcoMotors is focused now on the truck market; last February the company signed a licensing agreement with Navistar. "When the economy has recovered, the world will add 85 million combustion engines for cars and light trucks," Hofbauer says. "If we can offer an engine that is efficient and competitive in production costs, it will be a success."

When a car or truck suffers major engine damage, the first reaction of most vehicle owners is to buy a new or used car or truck. This makes sense in some cases, but often, it isn’t necessary. Repowering your car or truck’s worn out engine with a rebuilt/remanufactured engine can also be considerably less expensive than buying a new or used car.
A rebuilt engine is one that is remanufactured to prescribed standards and specifications by highly-skilled machinists using state-of-the-art equipment and components. During this process, many of the new components installed meet or exceed the original equipment performance standards. Frequently, rebuilt engines are superior to new car engines because better parts are used, or design changes in parts correct problems with the original engine. Rebuilt/remanufactured engines are dependable, reliable, and backed by warranty programs.
A rebuilt engine gets better gas mileage than a worn-out engine and emits fewer pollutants. Engine repowering also saves energy related to processing discarded engines and cars.
The savings from engine repowering is notable when compared to the prices of new cars and trucks. A rebuilt/remanufactured engine purchased and installed at an average cost of $2,500-$3,500 is a sound and attractive investment. Typically, a professionally rebuilt engine comes with a one-year or 12,000 mile warranty but some of these warranties can be as long as 36 months or 36,000 miles.

That, of course, is the exact reason why I love my old big block engine cars. I love to crawl under the hood and be able to do what I want to the motor. If I want to bore out the engine and add custom aftermarket parts, like the classic car grease-monkey I am, then it is very doable. Tweaking your classic muscle car to drive and sound just you want is very doable for the diy mechanic like myself.

are generally heavier, noisier, and more powerful at lower speeds than . They are also more fuel-efficient in most circumstances and are used in heavy road vehicles, some automobiles (increasingly so for their increased over gasoline engines), ships, , and light . Gasoline engines are used in most other road vehicles including most cars, , and . Note that in , sophisticated diesel-engined cars have taken over about 45% of the market since the 1990s. There are also engines that run on , , , (LPG), , and (TVO).
