1. Combustion System:
* Cylinder: The space where combustion occurs.
* Piston: Moves up and down within the cylinder, driven by the force of the explosion.
* Connecting Rod: Connects the piston to the crankshaft.
* Crankshaft: Converts the linear motion of the piston into rotational motion.
* Camshaft: Controls the timing of the valves.
* Valves: Allow air and fuel to enter the cylinder and exhaust gases to exit.
* Spark Plug (Gasoline Engines): Ignites the air-fuel mixture.
* Fuel Injector (Diesel Engines): Injects fuel directly into the cylinder.
2. Intake and Exhaust System:
* Intake Manifold: Directs air to the cylinders.
* Exhaust Manifold: Collects exhaust gases from the cylinders.
* Air Filter: Filters incoming air to protect the engine.
* Exhaust Pipe: Carries exhaust gases away from the engine.
* Muffler: Reduces noise from the exhaust system.
3. Cooling System:
* Radiator: Cools the engine coolant.
* Water Pump: Circulates coolant through the engine.
* Thermostat: Controls the flow of coolant to the radiator.
* Cooling Fans: Force air through the radiator.
4. Lubrication System:
* Oil Pan: Stores engine oil.
* Oil Pump: Circulates oil through the engine.
* Oil Filter: Removes contaminants from the oil.
5. Fuel System:
* Fuel Tank: Stores fuel.
* Fuel Pump: Delivers fuel to the engine.
* Fuel Lines: Carry fuel from the tank to the engine.
* Fuel Filter: Filters fuel before it reaches the engine.
6. Electrical System:
* Battery: Provides electrical power to start the engine.
* Alternator: Generates electrical power for the engine while it is running.
* Starter Motor: Cranks the engine to start it.
* Ignition System (Gasoline Engines): Provides electrical energy to the spark plugs.
7. Accessories:
* Air Conditioner Compressor: Compresses refrigerant for air conditioning.
* Power Steering Pump: Provides power assistance for steering.
* Alternator: Generates electrical power for the vehicle.
This list provides a general overview of the main parts of an engine. There are many other smaller parts that contribute to the engine's operation. The specific components and their configuration will vary depending on the type of engine (e.g., gasoline vs. diesel, 4-stroke vs. 2-stroke) and the vehicle it is powering.
