Is your engine underperforming? Our expert shares how a diesel engine compression test could provide the diagnosis.

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.

The diesel engine has a 23:1 compression ratio, which would quickly lead to detonation if fueled with gasoline. This needs to be reduced closer to 10:1 if the engine is to run safely on gas.

What Are Naturally Aspirated Diesel Engines? Unlike gasoline engines, which rely on spark plugs to ignite the air-fuel mixture, diesel engines use compression ignition. This process involves ...

High compression, typical of diesel engines, is no longer needed to make the fuel ignite; in fact, the chemistry causing this auto ignition process exists only at lower compression ratios.

Mazda is first with plans for a compression (diesel) engine that burns gas. The SkyActiv-X 2019 Mazda will get 20 to 30 percent better fuel economy than a gasoline ignition engine.

It may be a main power source for modern work trucks, but these obscure diesel engines show compression ignition designs have taken lots of forms in the past.

Most heavy-duty diesel pickups need two standard batteries to provide enough amps to crank over their high-compression engines.
