Diesel engines do their hardest work in the toughest jobs, from highway semis to construction equipment, and the reason they ...

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 ...

SAE Transactions, Vol. 96, Section 4: RECIPROCATING ENGINES–SPARK IGNITION AND DIESEL (1987), pp. 614-623 (10 pages) A single-cylinder, variable–compression ratio, direct–injection diesel engine was ...

A homogeneous charge compression ignition (HCCI) gasoline engine has been something of a holy grail for internal combustion engineers for decades, promising the fuel economy of diesel engines but ...

Diesel’s on the outs in Europe, and EVs aren’t ready for prime time. Skyactiv-X seems, at this juncture, a hedge bet against both aspects. EV infrastructure lags massively behind our petroleum ...

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. Share on Facebook ...

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.
