Yes, bad gas can cause the check engine light (CEL) to come on. Poor quality fuel may not combust properly, leading to inefficiencies in the engine's operation. This can trigger the car's onboard diagnostics system (OBD-II) to detect anomalies such as misfires or unusual emissions levels, subsequently illuminating the CEL. To mitigate this, it's advisable to buy fuel from reputable stations. Should you suspect bad gas is the culprit after a recent fill-up, it's wise to drain the tank and refill with high-quality gasoline. Additionally, adding a fuel system cleaner to your tank might help by removing any deposits that have built up. However, if the CEL remains lit, it's crucial to have your vehicle checked by a professional to prevent potential damage.
An internal combustion engine, also known as a fuel engine, is a machine that converts chemical energy stored in fuel into mechanical energy which can propel a vehicle. It works through a cycle of steps that repeat in a specific order.
1. Intake: During the intake stroke, the piston moves downward, drawing a fresh charge of vaporized fuel/air mixture.
2. Compression: The intake valve closes, the cylinder moves upward, and compresses the fuel/air mixture.
3. Combustion: When the piston reaches its highest point (top dead center), the spark plug ignites the fuel/air mixture. This explosion pushes the piston back down.
4. Exhaust: The exhaust valve opens, the piston moves upward, and pushes out the exhaust gas mixture left over after fuel combustion.
5. This cycle then repeats for as long as the engine is in operation.
Basically, a fuel engine works by igniting a fuel-air mixture in a combustion chamber. The resulting hot gases push a piston, which in turn rotates the crankshaft, providing power to the wheels.
