Diesel and gasoline emissions have become some of the leading concerns regarding greenhouse gases and global climate change. While diesel engines are more efficient than gasoline-powered engines, they ...

Diesel and gasoline fuel sources both bring unique assets and liabilities to powering internal combustion engines. But what if an engine could be programmed to harvest the best properties of both fuel ...

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 ...

A.Here's a pressure-volume diagram for a combustion engine. Although rough, it is an approximation of the so-called air-standard cycle. '' Point (a) is at atmospheric pressure, after which the air is ...

As demand climbs for more fuel-efficient vehicles, knowledge compiled over several years about diesel engines and a new strategy known as “low-temperature combustion” (LTC) might soon lead auto ...

The diesel engine was one of the most ambitious engineering undertakings in history. It was so radical and high-minded that it still hasn’t been totally perfected—even after 150 years of development.
