What is the Difference Between Gas and Diesel Engines?

How do diesel engines work?

With all the emissions scandals surrounding Volkswagen, Mercedes, Fiat, and even Harley-Davidson, we’ve been talking a lot about diesel engines in the last year, but how many of our readers really understand how diesel engines work compared to gas engines? How many of them really understand how a conventional four-cycle engine works in the first place?

Instead of asking, we’re just going to show you- with more than a little help from this terrific diesel and four-cycle comparison video put together by the gearheads over at CarThrottle. Like them, we’re curious to hear about which of the two concepts you’re a bigger fan of in the comments section- and, no, we’re not terribly interested in discussing how obsolete ICEs may or may not be (save that for the EV posts). Enjoy!
