Camshaft for Mercedes-Benz OM404

The camshaft part number A4040512201 is a rotating component within the Mercedes-Benz OM404 engine. It features specific lobes that actuate the valve train, ensuring the precise opening and closing of intake and exhaust valves. By regulating the valve timing, this component manages the intake of the air-fuel mixture and the expulsion of exhaust gases during the engine combustion cycle.

This part is manufactured for the Mercedes-Benz OM404 engine. It is engineered to meet the specific rotational and synchronization requirements of this engine model. Proper installation ensures that the valve events occur at the correct intervals relative to the piston position, which is necessary for the engine to operate within its design parameters.

In internal combustion engines, the camshaft is driven by the crankshaft and serves as the primary timing mechanism for the valve train. The profile of the lobes determines the lift and duration of the valve opening, which directly influences the volumetric efficiency and power characteristics of the engine. Maintaining the integrity of the camshaft lobes is necessary to prevent timing deviations that can affect engine performance and exhaust gas composition.
