Распределительный вал основного двигателя Caterpillar 1078369

The Primary Engine Camshaft operates the intake and exhaust valves through a timed rotational sequence, controlling airflow into and out of the engine cylinders. Driven by the crankshaft via a timing mechanism, the camshaft converts rotational motion into linear valve movement using lobes for specific lift and duration. Emissions control and engine performance consistency are ensured by ensuring valves open and close at the correct intervals throughout all engine speeds and loads.Attributes:• Supports high-speed operation without valve float.• Balanced to minimize torsional vibration during rotation.• Controls valve overlap to influence exhaust scavenging.Applications: The Primary Engine Camshaft is installed in the engine block and controls valve timing to regulate airflow in combustion chambers for engine power generation.
