It explains steam engines, which are reciprocating external combustion engines, and compares them to internal combustion engines, such as gasoline and diesel engines. The four-stroke cycle of an ...

Audi says the combustion method in the new engine is similar to the Miller cycle, which leaves the intake valve open during part of the compression stroke and makes the engine compress against the ...

In 1876, Nicolaus Otto, Gottlieb Daimler, and Wilhelm Maybach developed and patented the four-cycle, compressed-charge engine. (Germany) In 1886, Karl Benz started the first commercial production of ...

Also, the engine is a modular design, which, according to the NEVIS team, enables a manufacturer to easily configure multiple arrays of cylinders (2, 4, 5, 6, 8, etc.) in an engine from the same ...

Unfortunately, like the other combustion cycles outlined here, that engine also produces a lot of hydrocarbon and carbon monoxide emissions. There are fewer CO2 emissions, though, which is a bonus.

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 Wild Tomahawk Internal Combustion Turbine Engine Could Dramatically Chop Fuel Use and Emissions. Small, ultra-fast, primary and “afterburner” secondary combustion events promise to deliver ...

Audi has an impressive slate of internal combustion engines on offer at the moment, including the 591-hp twin-turbo 4.0-liter V-8 you see above, powering the jaw-dropping RS 6 Avant super-wagon.
