Piston engines used in general aviation burn Avgas, releasing toxic lead. Aviation's environmental footprint can be reduced by better fuel economy in aircraft, or air traffic control and flight routes can be optimized to lower non-CO 2 effects on climate from NO x, particulates or contrails.
Engine designers had always been aware of the many limitations of the rotary engine, so when static style engines became more reliable and gave better specific weights and fuel consumption, the days of the rotary engine were numbered. Rotary engines had a fundamentally inefficient total-loss oiling system. In order to reach the whole engine ...
The health and environmental impact of transport is significant because transport burns most of the world's petroleum. This causes illness and deaths from air pollution , including nitrous oxides and particulates , and is a significant cause of climate change through emission of carbon dioxide .
1972 GM Rotary engine cutaway shows twin-rotors. Popular Science magazine in the May 1972 article "GM Rotary Engine for the 1974 Vega", an illustration of the Wankel installed in a 1974 Vega hatchback showed a different grille, a lower, more sloped hood line, and a "GM Rotary" badge and Wankel crest on the rear quarter panel. They stated the ...
Clerget are best known for their well engineered rotary engines produced from 1911 to the end of World War I in 1918, the first of their type to deliver fuel-air mixture to the cylinder heads by external induction tubes via externally push rod operated inlet valves. They later made a series of static radial aircraft diesel engines.
Libralato engine. A pistonless rotary engine is an internal combustion engine that does not use pistons in the way a reciprocating engine does. Designs vary widely but typically involve one or more rotors, sometimes called rotary pistons. Although many different designs have been constructed, only the Wankel engine has achieved widespread adoption.
