What Happens When an Engine Fails?

[ValeriaMarie]

When an engine fails, the following situations may occur: 1. Sensor-related faults: such as coolant temperature sensor, crankshaft sensor, oxygen sensor, etc. 2. Poor combustion of the air-fuel mixture: issues with the engine's spark plugs, ignition coils, fuel pump, or clogged fuel lines can all lead to poor combustion of the air-fuel mixture. 3. Air intake problems: The engine requires air intake during combustion, making the air filter crucial. If the car's air filter is dirty and not cleaned regularly, it can affect the air intake, potentially leading to blockages over time. Severe cases may cause the engine warning light to illuminate. 4. Turbocharging issues: Problems with the intake boost pipes or turbocharger can also trigger the engine warning light. The most common issue is turbocharger damage, accompanied by symptoms such as oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust.
