Gasoline and also diesel vehicles are similar. Lock both usage internal combustion engines. A gasoline auto typically offers a spark-ignited internal burning engine, quite than the compression-ignited systems provided in diesel vehicles. In a spark-ignited system, the fuel is injected into the combustion chamber and combined with air. The air/fuel mixture is ignited through a spark from the spark plug. Although petrol is the most usual transportation fuel, there are alternate fuel choices that use similar components and engine systems. Learn around alternative fuel options.

You are watching: What is the gas thing on a car called


Battery: The battery provides electrical power to start the engine and power car electronics/accessories.
Electronic manage module (ECM): The ECM controls the fuel mixture, ignition timing, and emissions system; monitors the procedure of the vehicle; safeguards the engine indigenous abuse; and detects and also troubleshoots problems.
Exhaust system: The exhaust system channels the exhaust gases native the engine out v the tailpipe. A three-way catalyst is draft to mitigate engine-out emissions in ~ the exhaust system.
Fuel filler: A nozzle native a fuel dispenser attaches to the receptacle ~ above the vehicle to to fill the tank.
Fuel injection system: This mechanism introduces fuel into the engine's burning chambers for ignition.
Fuel line: A steel tube or flexible hose (or a combination of these) move fuel indigenous the tank to the engine's fuel injection system.
Fuel pump: A pump that transfers fuel indigenous the tank to the engine's fuel injection system via the fuel line.
Fuel tank (gasoline): This tank stores gasoline on plank the car until it's needed by the engine.
Internal combustion engine (spark-ignited): In this configuration, fuel is injected right into either the entry manifold or the burning chamber, where it is merged with air, and the air/fuel mixture is ignited through the spark indigenous a spark plug.
Transmission: The infection transfers mechanical strength from the engine and/or electric traction engine to journey the wheels.
