Car Oil Pumps

The engine oil pump draws oil from the oil pan and delivers it at appropriate pressure to various lubrication points in the engine, such as bearings, piston rings, and camshaft, ensuring adequate lubrication and assisting in cooling by removing heat.

Variable Timing Solenoid

Car Camshafts

A shaft with several cams used to drive valves or the movement of valve and unit injector pump or pump nozzle plunger at predetermined moments during the engine's operating cycle.

Car Camshaft Phaser

Adjusts the intake and exhaust camshafts' relative positions to change valve timing, optimizing combustion for better fuel efficiency and performance.

Car Glow Plug

Provides heat to improve diesel engine start-up in cold conditions, with rapid heating and sustained high temperature.

Car Vacuum Pumps

The engine vacuum pump creates vacuum suction using low-pressure areas generated during engine operation, providing power for the vehicle's brake system, air conditioning system, and some sensors.

New Energy Scroll Compressor

A scroll compressor is a rotary positive displacement compressor. It uses two interlocking scrolls to form crescent-shaped chambers. As the scrolls rotate with a small radius, the chambers change size, achieving intake, compression, and exhaust.
