DIFFERENT CAR ENGINES

Engine System 


Diesel Engine

 In 1878, Rudolf Diesel was attending the Polytechnic High School of Germany (the equivalent of an engineering college) when he learned about the low efficiency of gasoline and steam engines. This disturbing information inspired him to create an engine with a higher efficiency, and he devoted much of his time to developing a "Combustion Power Engine." By 1892 Diesel had obtained a patentfor what we now call the diesel engine


HEMI Engine

The HEMI engine for automobiles was born in 1948 -- Harry Westlake and several others developed a Hemi 6-cylinder engine for Jaguar. A few years later, in 1951, Chrysler introduced a 180-horsepower HEMI V-8 engine on several models. The Chrysler HEMI engine had a displacement of 331 cubic inches (5.4 liters), so it is known as the "331 HEMI."

These days, 180 horsepower sounds like nothing. But in 1951, 180 horsepower was unheard of. It was an amazing amount of power for the day, and it fueled the "HEMI legend."
Rotary Engine

A rotary engine is an internal combustion engine, like the engine in your car, but it works in a completely different way than the conventional piston engine.


The rotary engine (originally conceived and developed by Dr. Felix Wankel) is sometimes called a Wankel engine, or Wankel rotary engiIn a piston engine, the same volume of space (the cylinder) alternately does four different jobs -- intake, compression, combustion and exhaust. A rotary engine does these sam e four jobs, but each one happens in its own part of the housing. It's kind of like having a dedicated cylinder for each of the four jobs, with the piston moving continually from one to the next.

Radial Engine

If you have ever seen a World War II bomber like the B-25 or the B-17, or if you have ever seen or been on an old commercial airplane like a DC-3, then you are familiar with something called a radial engine. Many planes of the WWII era used very large, very powerful radial engines to drive their propellers.
In this article, you will learn how the radial engine works, what makes it different from other engine configurations and why it fits in so well with airplanes.
