- Crankshafts – Key to transmitting energy generated in the combustion process to drive systems.
- Engine heads – They contain valves, camshafts and combustion chambers, ensuring proper air and fuel flow.
- Engine, main and crank bearings – Ensure smooth and safe movement of the crankshaft and pistons.
- Oil drain and filler plugs and dipsticks – They make it easier to check the oil level and change it.
- Pistons and ring – Key elements of the combustion process that compress the fuel-air mixture and transfer energy to the crankshaft.
- Oil filters – Protects the engine against contamination in the lubrication system.
- Oil pans – Store the oil and ensure it is evenly distributed throughout the engine.
