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

While the first Otto cycle patent was filed in 1887, Rudolf Diesel developed an alternate cycle for use in an internal combustion engine, with his first patent filed in 1898. Diesel's engine ...

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.

Rudolf Diesel invented the compression ignition ... induction to clean up the exhaust over a DI engine. Since any Otto cycle engine's output is dependent on the amount of air the pistons can ...

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.

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 ...

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.

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 ...
