A car engine is the heart of any vehicle, converting fuel into motion through a series of mechanical processes. Here are the main components that make it all work: Engine block The engine block is the foundation of the engine. It houses major parts such as cylinders, pistons and the crankshaft. It is usually made of cast iron or aluminium. Cylinders These are chambers where fuel combustion takes place. Engines can have 3, 4, 6 or 8 cylinders, depending on the car's design and power requirements. Pistons Pistons move up and down inside the cylinders. They help convert the energy from fuel combustion into mechanical energy. Crankshaft The crankshaft is connected to the pistons and rotates as they move, converting vertical motion into rotational power that drives the wheels. Camshaft The camshaft controls the opening and closing of the intake and exhaust valves, ensuring the correct timing for air and fuel flow. Spark plugs Spark plugs ignite the air-fuel mixture in the cylinders, causing combustion. This is what makes the pistons move. Valves The intake and exhaust valves control the intake of the air-fuel mixture and the exhaust of the exhaust gases. They work in sync with the camshaft. Timing belt This belt synchronizes the movement of the crankshaft and camshaft, ensuring proper timing and engine performance. Oil sump Located at the bottom of the engine, the oil sump stores engine oil, which is essential for lubrication and cooling. Radiator The radiator is part of the cooling system. It helps maintain the engine temperature by dissipating heat from the coolant.
