nestekaasumoottorit

Nestekaasumoottorit are internal combustion engines that run on liquefied petroleum gas (LPG), commonly known as autogas. These engines operate similarly to gasoline engines but are designed to utilize LPG as their fuel source. The primary difference lies in the fuel delivery system, which typically involves a vaporizer that converts liquid LPG from the tank into a gaseous state before it enters the engine's intake manifold.

LPG is stored under pressure in a liquid form in a specialized tank. When the engine requires fuel, the liquid LPG is drawn from the tank and passed through a regulator or vaporizer. This device uses engine heat or a small amount of coolant to warm the LPG, causing it to turn into a gas. The gaseous LPG is then mixed with air and delivered to the cylinders for combustion. Spark plugs ignite the air-fuel mixture, producing power.

Compared to gasoline engines, nestekaasumoottorit often offer advantages such as lower emissions of certain pollutants like hydrocarbons and carbon monoxide. They can also be more cost-effective due to the generally lower price of LPG compared to gasoline in many regions. However, the initial cost of converting a gasoline engine to run on LPG can be a factor. The availability of LPG refueling stations can also vary depending on the location. Modern nestekaasumoottorit are available in both factory-fitted and retrofitted configurations for a wide range of vehicles.
