A remote starter switch and a top-quality, screw-in-type compression gaugeâ such as these models from Sears, Roebuck & Companyâ can be used to measure the pumping efficiency of an engine, as well as ...

With all the recent emphasis on electric vehicles, we often overlook the technology that still powers most cars on the road today. The internal combustion engine (ICE) has been at the heart of the ...

Air flowing into a four-stroke diesel engine gets cleaned as it passes through the air filter. It then flows through tubing until it is compressed in the spinning blades of the turbo. As a result, the ...

You'd think that the pistons listed for a 10.5:1 compression ratio would actually give you 10.5:1. But it's usually not that simple. Perhaps that's why so many four-wheelers have a foggy or incomplete ...

If you often build, rebuild, or are just plain curious about optimizing the power from your engine, this subject is required readingand critical to producing race-winning horsepower. Simply stated, ...

This means that the high torque efficiency of the two-stroke engine is kept, while the cleanliness and longevity of the four-stroke engine is gained. A win-win scenario. What’s more, the exhaust ...

Diesel engines can technically run backwards, though there's very little (if any) practical applications for this, especially ...

Dim’s fascination with cars began when he was just six. Born into a family of car enthusiasts and racing drivers, he started learning basic mechanics and driving from an early age. While he loves ...
