Some engines use a spark to ignite their fuel, and others rely on compression. What does all of that mean? And how do the two kinds of engines differ?

Two primary types of internal combustion engines exist: a spark ignition gasoline engine and a compression ignition diesel engine. Spark ignition and compression ignition differ in how each delivers ...

Having ample heat in the combustion chambers is key to making HCCI work. The engines use a conventional spark ignition for cold starts and when HCCI is disengaged.

The plasma technology systems increase exhaust flow and reduce harmful emissions to help improve gasoline and diesel engine performance. Learn more here on CCJ.

Swapping spark plugs for nanopulses could boost engine efficiency by 20% More precise ignition events mean better fuel efficiency and fewer pollutants.

In this work, a light-duty research engine based on a passenger car engine is equipped with an in-house developed pre-chamber (PC) ignition system replacing the conventional spark plug.

Could Pre-Combustion Ignition Save Combustion Engines? The main problem with combustion in today's world is the harmful pollutants produced by the incalculable number of vehicles in use.

Diesel engines don’t have spark plugs; instead, they use the super-heated air created by their high compression ratios to ignite the diesel fuel as it’s injected into the cylinder.
