Low- And High-Compression Fuel Economy Engines: The Techniques Are About The Same, But The Approach To Each Is Somewhat Different. A.Most stock cylinder heads have factory-cut undercuts of the type ...

You own a diesel-powered vehicle and are thinking of giving it a tuneup. But does your diesel even have spark plugs to change? The short answer is no, diesel engines do not have spark plugs. Instead, ...

You might have heard about high compression ratios, but what exactly are they, and what kind of effect do they have on an ...

Gasoline and diesel engines are very different. The former rely on spark ignition while the latter use compression ignition. Diesel engines typically run at much higher compression ratios than ...

We love ourselves a good oddball engine, and tiny, scrappy Mazda certainly must be responsible for more such engine concept patents per market-capitalization dollar than any other. We just discovered ...

50% fuel economy over current gasoline engines. It operates kind of like a diesel engine. The one demonstrated is a single cylinder engine but they are working on multi-cylinder engines. Still... if ...
