Cylinder block - The main housing for the engine's cylinders and crankshaft, providing support and rigidity to the engine and serving as a mounting point for various components.
Cylinder head - The top portion of the engine block that contains the combustion chamber, valves, and other critical engine components.
Pistons - These are cylindrical components that fit inside the engine's cylinders and are responsible for transferring the force generated by the combustion of fuel and air into rotational force for the crankshaft.
Piston rings - These are thin bands that fit around the pistons and help to seal the combustion chamber, allowing the piston to move smoothly within the cylinder and preventing oil from leaking into the combustion chamber.
Connecting rods - These are the components that link the pistons to the crankshaft, transferring the force generated by the combustion of fuel and air to the crankshaft.
Crankshaft - The primary rotating component of the engine that converts the force generated by the pistons into rotational force to drive the machine.
Camshaft - A rotating shaft with specially shaped lobes that operates the engine's valves, controlling the flow of air and fuel into and out of the combustion chamber.
Timing gears and chains - These components help to synchronize the movement of the crankshaft and camshaft, ensuring that the engine's valves operate at the correct time during the engine cycle.
Valves (intake and exhaust) - These are components that allow air and fuel into the engine's combustion chamber and allow exhaust gases to escape from the engine after combustion.
Valve springs - These components help to keep the valves closed when the engine is not operating, ensuring that they seal properly and preventing air or fuel from leaking into the combustion chamber.
Valve guides - These are cylindrical components that guide the movement of the valves, helping to ensure that they operate smoothly and without excess wear.
Rocker arms - These components are used to translate the movement of the camshaft to the valves, helping to open and close them at the correct times.
Pushrods - These are components that link the camshaft and rocker arms, helping to translate the motion of the camshaft to the rocker arms.
Oil pump - This component is responsible for circulating oil throughout the engine, helping to lubricate and cool various engine components.
Water pump - This component helps to circulate coolant through the engine, helping to prevent overheating and maintain proper operating temperature.
Thermostat - A temperature-sensitive valve that helps to regulate the flow of coolant through the engine, helping to maintain proper operating temperature.
Radiator - A component that helps to dissipate heat from the engine and maintain proper operating temperature by transferring heat from the coolant to the surrounding air.
Fan belt - A belt that drives the engine's cooling fan, helping to circulate air over the radiator and maintain proper operating temperature.
Turbocharger (if equipped) - A component that increases the amount of air and fuel delivered to the engine, helping to increase power and efficiency.
Exhaust manifold - A component that collects exhaust gases from the engine's cylinders and directs them to the exhaust system.
Intake manifold - A component that directs air and fuel into the engine's cylinders.
Fuel injectors - Components that spray fuel into the engine's cylinders in a controlled manner, helping to ensure efficient combustion.
Fuel pump - A component that delivers fuel from the fuel tank to the engine, helping to ensure proper fuel delivery.
Fuel filters - Components that help to remove contaminants from the fuel before it enters the engine, helping to prevent damage and extend the life of various engine components.
