Piston
Converts the expanding force of gases into mechanical energy.
Crankshaft
Converts the reciprocating motion of pistons into rotational motion.
Spark Plug
Ignites the air-fuel mixture in the combustion chamber.
Camshaft
Controls the opening and closing of the engine's valves.
Cylinder
Houses the piston and where the combustion process takes place.
Connecting Rod
Connects the piston to the crankshaft and transfers motion.
Valve
Regulates the flow of gases into and out of the combustion chamber.
Fuel Injector
Delivers fuel to the combustion chamber.
Oil Pump
Circulates engine oil to lubricate moving parts.
Turbocharger
Increases engine power by forcing additional air into the combustion chamber.
Radiator
Dissipates heat from the engine coolant.
Thermostat
Regulates the engine's operating temperature by controlling coolant flow.
Air Filter
Cleans the incoming air before it enters the engine's intake system.
Alternator
Generates electricity to power the vehicle's electrical systems and charge the battery.
Battery
Stores electrical energy to start the engine and power electrical components.
Exhaust Manifold
Collects exhaust gases from the cylinders and directs them to the exhaust system.
Catalytic Converter
Reduces harmful emissions by converting exhaust gases into less harmful substances.
Oxygen Sensor
Measures the oxygen content in the vehicle's exhaust gases.
Engine Control Unit (ECU)
The vehicle's main computer responsible for controlling engine performance and emissions.
Knock Sensor
Detects engine knocking and allows the ECU to prevent it.
Mass Air Flow Sensor
Measures the mass of air entering the engine's intake system.
Throttle Body
Regulates the amount of air flowing into the engine.
Fuel Pump
Delivers fuel from the tank to the engine's fuel injection system.
Serpentine Belt
Drives various engine accessories such as the alternator, power steering pump, and air conditioning compressor.
Timing Belt/Chain
Maintains the timing between the crankshaft and the camshaft for proper engine operation.
Oil Filter
Cleans the engine oil from contaminants.
Coolant Pump
Circulates coolant through the engine and the radiator to remove excess heat.
Intake Manifold
Distributes the air-fuel mixture to each cylinder evenly.
EGR Valve
Recirculates a portion of the exhaust gases back to the engine's intake to reduce NOx emissions.
