Liquefied Natural Gas Trucks

Heavy-duty liquefied natural gas (LNG) vehicles work Much like gasoline-powered vehicles with a spark-ignited internal combustion engine. The natural gas is super-cooled and cryogenically stored in liquid form, Usually in a tank on the side of the truck. LNG is typically a more expensive option than compressed natural gas (CNG) And is most often used in heavy-duty vehicles to meet long-range requirements. Because it is a liquid, the energy density of LNG is greater than CNG, So, more fuel can be stored onboard the vehicle. This makes LNG well-suited for Class 7 and 8 trucks traveling greater distances. Key Components of a Liquefied Natural Gas Truck Battery: The battery provides electricity to start the engine and Power vehicle electronics/accessories. Also, read - How Do Propane Vehicles Work? Electronic control module (ECM): The ECM controls the fuel mixture, ignition timing, And emissions system; monitors the operation of the vehicle; Safeguards the engine from abuse, And detects and troubleshoots problems. Exhaust system: The exhaust system channels the exhaust gases from the engine out through the tailpipe. A three-way catalyst is designed to reduce engine-out emissions Within the exhaust system. Fuel filler: A nozzle from a high-pressure hydrogen dispenser attaches to; The receptacle on the vehicle to fill the tank.

Also, read - Common Spark Plug Misfire Symptoms Fuel line: A metal tube or flexible hose (or a combination of these) Transfers fuel from the tank to the engine's fuel injection system. Fuel tank (liquefied natural gas): Stores liquefied natural gas on board the vehicle until it's needed by the engine. Internal combustion engine (spark-ignited): In this configuration, fuel is injected into either the intake manifold Or the combustion chamber, Where it is combined with air, And the air/fuel mixture is ignited by the spark from a spark plug. Transmission: The transmission transfers mechanical power from the engine, And/or electric traction motor to drive the wheels. See more: How Do Propane Vehicles Work?
