Compressed natural gas vehicles require a greater amount of space for fuel storage than conventional petrol-powered vehicles. Since it is a compressed gas, rather than a liquid like petrol, CNG takes up more space for each GGE (petrol gallon equivalent). However, the cylinders used to store the CNG take up space in the trunk of a car or bed of ...
This gas is compressed as the flame propagates and the pressure in the combustion chamber rises. The high pressure and corresponding high temperature of unburnt reactants can cause them to spontaneously ignite. This causes a pressure wave to traverse from the end gas region and an expansion wave to traverse into the end gas region.
There are two types of autogas equipment and autogas stations as well: LPG (propane-butane mix) and compressed natural gas (CNG, methane). Natural gas is stored at a higher pressure than LPG (200 bar vs. 10 bar for LPG). The main consumer of LPG is commercial light-weight cargo transport (so as GAZelles in Russia are mostly LPG-powered).
A motor fuel is a fuel that is used to provide power to the engine of motor vehicles — typically a heat engine that produces thermal energy via oxidative combustion of liquid or gaseous fuel and then converts the heat into mechanical energy through reciprocating pistons or gas turbines.
A natural gas vehicle (NGV) utilizes compressed natural gas (CNG) or liquefied natural gas (LNG) as an alternative fuel source. Distinguished from autogas vehicles fueled by liquefied petroleum gas (LPG), NGVs rely on methane combustion, resulting in cleaner emissions due to the removal of contaminants from the natural gas source.
Compressed fluid may also be used as a simple vehicle propellant, with the potential energy that is stored in the compressed fluid used to expel the fluid as the propellant. The energy stored in the fluid was added to the system when the fluid was compressed, such as compressed air. The energy applied to the pump or thermal system that is used ...
