LPG, CNG, LNG, NGV ... what does it all mean? After the turn. LPG, which is of English - Liquified Petroleum Gas: liquid fuel gas, liquefied petroleum gas or liquefied petroleum gas. And the rest? ... ie CNG Compressed Natural Gas means compressed natural gas. LNG: Liquefied Natural Gas liquefied natural gas. NGV (Natural Gas for Vehicles) is a natural gas powered vehicles.
And how it all works? The same principle of a piston engine is probably known to anyone interested in motoring and present it here more is unnecessary. It has not changed properly from the beginnings of the automotive industry. I write only: A mixture of fuel and air - given to the cylinder chamber is subject to compression, by sliding in the piston during the compression stroke and then spark at the spark plug causes an explosion. The resulting pressure causes the piston travel and the associated crank mechanism converts reciprocating piston motion into rotation of the crankshaft. This move by the other mechanisms drives the car.
use gas as a fuel does not interfere with the principle of operation of the engine. Fuel essential, that is, less gasoline or diesel, the fuel is replaced by a second, so called. alternative. Gaseous fuel is introduced into the combustion chamber (cylinder) already in the form of mixtures with air almost always. The mixture enters the cylinder through the intake valves. Place of application, fuel type and its condition is different depending on the gas system and its kind. This is due to technological sophistication of the engine. There are so
. generation of gaseous fuel supply systems.
In systems I and II generation mixture of gas - air is formed in the mixer, and through it gets to the central power system - even before the air damper - through the carburetor and manifold intake to the engine, where is sucked into the cylinder. The Generation IV systems gas fed through a gas injector for each cylinder individually. These types of devices allow the injection of gas in portions for each cylinder and adjusting the wires to the intake manifold near the intake valves (with air damper), which has numerous advantages.

There are systems for generation of V
It is also a gas injection system - just as the fourth generation with the difference that here the gas injection takes place not in the volatile phase and the liquid. Thanks to this cooling effect is used an expanded gas, resulting in a higher degree of filling the cylinders and thereby increase engine power and even better use of injected fuel. The third generation be forgotten because there is hardly displaced by more modern systems.
difference in the operation of CNG and LPG involves several problems. First of all, the fact that each element through which the CNG is designed to maintain high pressure, which does not occur at the fuel systems of LPG. Of course, that installation does not supply propane and natural gas. Most typically the tank or tanks is (are) located (e) under the vehicle floor or roof. They are made of steel but not stainless steel coated with polymers or composite armored. Much more often, CNG is used in diesel engines.
And now for what it's all ? First of all, because it is cheaper . Then, because the more environmentally finally - although this probably bear a misunderstanding, because safer.
