How Do Car Engines Work?

November 16th, 2017 by

At Glenbrook Dodge Chrysler Jeep RAM and FIAT, your Fort Wayne new and used car dealership, we believe that the more informed our customers are, the happier they will be with their car buying decision. To accomplish this, we would like to explain the basics of the heart of all automobiles: the engine.

How Engines Work
Engines, and by extension cars, are powered via combustion. Combustion is effectively a controlled explosion that creates energy to move the various moving pieces that propel the car. These explosions are created using pistons that are housed in cylinders.

The number of cylinders an engine has is directly correlated to its output in the form of torque and power. Most engines have as few as four and up to as much as 12. The number of cylinders will usually determine the design of the engine as well. Four-cylinders are lined in a formation, appropriately enough, called inline. Once you get to six-cylinders, you start seeing the cylinders arranged in a “V” shape to cut down on space, which is why they’re often called a “V6”.

The combustion created in the cylinders requires fuel. The more cylinders, the more fuel. This can cause higher cylinder engines to be somewhat lacking in fuel economy when compared to four-cylinder engines. In recent years, this effect has been mitigated quite a bit by design innovation. V6 engines have the closest to the fuel efficiency of 4-cylinder engines.

Another thing to consider is pricing. If you look at a 2018 Jeep Grand Cherokee with a V6 engine, you will find it quite a bit more economical than the same model with a V8 engine, even with all else being equal. The question becomes whether or not the improved performance is worth the additional cost in relation to your needs.
