Wärtsilä has announced the results of extensive testing of its 4-stroke ammonia engine, which demonstrated a reduction in ...

The key advantage is higher efficiency than is achievable in an Otto engine ... His cycle was intended for use with two- and four-stroke engines running on gasoline, diesel, or gaseous fuels ...

Certainly the most common is the Otto cycle, or spark ignition engine, or gasoline engine. The Diesel cycle has certainly seen rejuvenation of late and will be the topic of another column.

The Otto cycle was the basis of all gasoline engines ... V-6 engines without having to resort to turbochargers or diesel fuel. While the Atkinson cycle does a great job of maximizing fuel economy ...

The alleged experts claim that the engine Nicolaus Otto invented in 1876 is running ... Michigan's Automotive Research Center. Nuances of diesel and gasoline engines peacefully coexist in cold ...

Nearly everyone has heard of a diesel engine, but nearly everyone actually has an Otto-cycle engine. Call it a four-banger, a five-point-oh, a V8, or any other gearhead term—they’re all ...

The charge of course consists of combustible mixture in the Otto engine, and air in the Diesel engine. Compression and working stroke then follow as in the case of the four-cycle engine.

Most modern gasoline and diesel-powered engines found in the cars and trucks seen on today's roadways rely on the four-cycle-engine principles developed in the late 1800s by Nikolaus Otto ...

Since the earliest days of the automobile in late 19th century, the dominant powerplant has been the reciprocating piston, spark-ignition Otto-cycle, followed by the compression-ignition diesel.
