Application Of Powder Metallurgy Technology In The Automotive Industry

We know that many of the auto parts are gear constructions, and these gears are made by powder metallurgy. With the development of China's auto industry and the improvement of energy saving and emission reduction requirements, the application of powder metallurgy technology in the automotive industry. More and more, more and more metal parts will be produced by powder metallurgy.

1, VVT powder metallurgy parts

VVT or VCT (Variable Cam Timing System) adjusts the phase of the engine cam through the equipped control and execution system, so that the valve opening and closing time changes with the engine speed to improve the charging efficiency. , a system that increases engine power. The actuators of VVT or VCT systems—the core components of the phaser, the stator, the rotor, and the end caps are mostly powder metallurgy.

2. Powder metallurgy parts in the oil pump

At present, most of the engine oil pump and the automatic transmission oil pump are quantitative oil pumps, and the quantitative oil pump is generally an external gear pump, an internal meshing cycloid pump or an internal gear pump. The gears of this type of pump are manufactured using a powder metallurgy process.

3. Powder-assisted vacuum pump powder metallurgy parts

For diesel-driven vehicles, the same level of vacuum pressure cannot be provided at the intake manifold because the engine is pressure-combusted, so a vacuum pump is required to provide a vacuum source. The power of the vacuum pump is directly obtained from the engine. The power drives the powder metallurgy rotor through the powder metallurgy coupling to drive the plastic valve piece. The rotor and the pump chamber have a certain amount of eccentricity, and the rotation of the valve piece generates a vacuum. Dynamic assistance.
