The throttle of a motor vehicle determines the load on the engine during idling and motion by controlling the fuel spray pulse width and ignition timing.
The throttle flap valve controls the size of the air intake, and the level of engine power, via a transducer. Throttles tend to accumulate large amounts of dirt from air pollution and poor fuel quality, and the combustion of gasoline can also cause buildup of carbon deposits. Due to the effect of negative pressure, this foreign matter will affect throttle action; for instance, a throttle that closes poorly will allow excessive air flow, which together with signal transmission errors will cause high fuel consumption and shaking when the engine is idling. Apart from the buildup of contaminants in the throttle valve, failure of the valve rotation bearings should not be ruled out as a contributing cause of these problems;
One end of the throttle mechanism designed to swing the other end of the metal using conventional metal rolling bearings sliding bearings, but due to poor soil resistance, these bearings is prone to cause the throttle rotation is not smooth vehicle acceleration and idle jitter problems; EPB5Z excellent resistance to plastic bearing corrosion resistance and abrasion resistance and heat resistance can become throttle rotation catching solve problem solvers, EPB5Z plastic bearings in high-performance engineering plastics on the basis of a wear-friction properties were improved, the basis of retaining the original carrier and anti-corrosion greatly enhance the wear resistance of the bearing to meet the demand for the use of the throttle. EPB5Z plastic and metal shaft bearings regardless of mill or respond PPS + GF30 plastic shaft in the throttle oil are reflected in good durability.
