The NGV fleet is made up mostly of transit buses, but there are also some government fleet cars and vans, as well as an increasing number of corporate trucks replacing diesel versions, most notably Waste Management, Inc and UPS trucks. As of 12-Dec-2013, Waste Management has a fleet of 2000 CNG Collection trucks; as of 12-Dec-2013, UPS has 2700 ...
An alternative fuel vehicle is a motor vehicle that runs on alternative fuel rather than traditional petroleum fuels (petrol or petrodiesel). The term also refers to any technology (e.g. electric cars, hybrid electric vehicles, solar-powered vehicles) powering an engine that does not solely involve petroleum. [citation needed]
A nitrous oxide engine, or nitrous oxide system (NOS) is an internal combustion engine in which oxygen for burning the fuel comes from the decomposition of nitrous oxide, N 2 O, as well as air. The system increases the engine's power output by allowing fuel to be burned at a higher-than-normal rate, because of the higher partial pressure of ...
The BAC One-Eleven airliner also used water injection for its Rolls-Royce Spey turbofan engines. Filling the tanks with jet fuel instead of water led to the Paninternational Flight 112 crash. [7] In 1978, Olympic Airways Flight 411 had to abort and return to its take-off airport due to a failure of the water injection system or its processes. [8]
Compressed natural gas. Compressed natural gas (CNG) is a fuel gas mainly composed of methane (CH 4), compressed to less than 1% of the volume it occupies at standard atmospheric pressure. It is stored and distributed in hard containers at a pressure of 20–25 megapascals (2,900–3,600 psi; 200–250 atm), usually in cylindrical or spherical ...
A Shell Autogas refuelling station. Autogas or LPG is liquefied petroleum gas (LPG) used as a fuel in internal combustion engines in vehicles as well as in stationary applications such as generators. It is a mixture of propane and butane. Autogas is widely used as a "green" fuel, as its use reduces CO 2 exhaust emissions by around 15% compared ...
Power-to-gas. Power-to-gas (often abbreviated P2G) is a technology that uses electric power to produce a gaseous fuel. [1] When using surplus power from wind generation, the concept is sometimes called windgas. [citation needed] Most P2G systems use electrolysis to produce hydrogen. The hydrogen can be used directly, [2] or further steps (known ...
Pumped air injection systems use a vane pump called the air pump, AIR pump, or colloquially "smog pump" turned by the engine via a belt or electric motor.The pump's air intake is filtered by a rotating screen or the vehicle air filter to exclude dirt particles large enough to damage the system.
