“The technology now exists to build spark-ignited engines that can deliver performance, economy and durability that are competitive with diesel for a broad cross-section of applications. What will ...

Diesel engines use compression to ignite the fuel, which needs to have an even burn, and cetane boosters have an important ...

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 ...

Diesel engines are different from gas engines in numerous ways, including their use of high compression ratios. Here's why that is and what it means.
