Diesel engines don't need spark plugs for combustion. It relies on high compression of superheated air and injecting diesel ...

the spark plug, which produces the zap of electricity that combusts the fuel/air combo, fires every four strokes (i.e., every other full crankshaft rotation). Meanwhile, in two-stroke engines ...

The defining characteristic of a two-stroke engine is to fire (combust) every time the piston is at top dead center. This makes them highly power dense, but also notoriously makes two-stroke engines ...

Air flowing into a four-stroke ... The fuel injector sprays into the smaller chamber, which also houses the glow plug. This is where combustion starts. The pressure differences of the two chambers ...

This equals a more violent explosion of the air/fuel mixture, meaning it sends the piston back down the stroke faster ... A diesel engine uses glow plugs instead of spark plugs.

That hot air-fuel mixture is then sucked into another chamber using a slider valve, where, because of the heat inside the cylinder, it ignites (without the use of a spark plug). That's where the ...

If you want to know what kind of bike engine fits your needs ... 222/Flickr In addition, these two-stroke powerplants are ideal for diesel fuel. This is why many heavy machines are using them.

Markus Berger That said, these Austrian two-stroke machines aren’t fuel-injected in the same way as your car. Under the hood, most modern engines feature direct injection, where fuel is squirted ...
