What are the symptoms of a wastegate valve failure?
The Turbocharger bypass valve is broken, which leads to increased gas leakage, which in turn reduces the gas cap efficiency. At this time, the diesel engine is weak, accelerated, or the exhaust pipe emits black smoke.
The basic element of the Tturbocharger bypass valve is: when the working pressure of the diesel engine intake port is higher than the calibration value, the mechanism acts on the turbocharger end to make the exhaust pipe wastegate valve, thereby reducing the exhaust gas according to the turbocharger. If the pressure is too high, the working pressure of the cylinder is too high, generally 2.5mpa is opened. If it is indeed damaged, the working pressure of the cylinder is too high. Damaged di often inwards are not easily revealed significantly.
The effect of using Turbocharger HE500WG Pressure Relief Valve for the supercharger is to better improve the low-speed characteristics of the supercharger. The cover is made smaller, which will improve the low-speed gear. Overspeed, to ensure high reliability, this way part of the diesel engine's gas waste bypass valve is off.
The raw materials selected at this stage are generally ferritic stainless steel. If the product is inspected, it should first consider whether it conforms to the design drawings, including specifications, raw materials, dimensional tolerances, etc. The tightness inspection is not completely guaranteed by the exhaust valve. It also depends on the production and processing conditions of the center shell. Of course, there are standards that can do some fatigue tests and high temperature deformation detection.
For the supercharger, the function basis of the exhaust valve is the same, only the appearance needs to be changed according to the supercharger meter, nothing else. There are many kinds of actuators, but the exhaust valve is relatively simple.
