Moteur

The engine is the power unit of a commercial vehicle, converting diesel fuel into the mechanical force that drives the wheels. This category covers the engine core components and the parts that keep it running, from the moving parts inside the block to the seals, mountings, and hardware around it. A truck engine is built to produce high torque and run reliably over long distances under heavy load.

In a diesel engine, air is drawn in and compressed in the cylinders until it is hot enough to ignite the injected fuel. The controlled combustion pushes the pistons, which turn the crankshaft and send power to the drivetrain. Supporting systems for fuel, air, cooling, and lubrication keep this process running within safe limits, and the engine parts are matched to the loads and temperatures it must handle.

Engine parts wear through heat, friction, and high mileage, and poor maintenance or contamination speeds it up. Signs of trouble include loss of power, unusual noises, excessive smoke, oil or coolant leaks, overheating, and warning lights. Because engine repairs are major work, regular servicing with the correct oil, coolant, and filters is the best way to extend engine life, and symptoms are best diagnosed early by a qualified technician.

The correct engine part depends on the engine model and specification, so it must be matched precisely. Confirm the part against the vehicle and engine specification before fitting.
