Anonymous users2024-02-05Common faults and troubleshooting of exhaust gas turbochargers, the reasons for the rotor shaft jamming caused by the turbocharger rotor shaft are low oil pressure, loose and oil leakage of the supercharger inlet pipe joint, resulting in oil shortage and jamming of the rotor shaft and bushing.
The bushing and pipe joint screw sleeve should be tightened, the oil is not cleaned, the bushing oil hole is blocked, the oil is changed, the oil filter is cleaned or replaced, and the sudden acceleration of the engine cold start causes the oil to have no time to lubricate the bushing.
Accelerating after a few minutes of idling, the engine often starts and stops urgently, and during the start and shutdown process, it should be idle for a few minutes, and then gradually increase or decrease the load. Black smoke from the supercharger, black smoke from the supercharger is often related to lubrication, the gap between the rotor shaft and the bushing is too large, the oil penetrates, the supercharger is overhauled, the bushing is replaced, the supercharger speed is low, and the engine power is insufficient will emit black smoke.
When such a phenomenon occurs, the intensifier exhaust release valve should be overhauled, specifically if the turbine or impeller is damaged, and the turbine or impeller should be replaced. The diaphragm of the exhaust release valve is broken, the diaphragm is replaced, the spring of the exhaust release valve fails, and the spring is replaced.
Check the intercooler, the supercharger speed is high, the pressure ratio increases resulting in rough engine work, and after finding that the engine works roughly, start to overhaul the supercharger exhaust valve and adjust the spring preload.
Specifically, there are two points: the hose of the exhaust vent valve is damaged. Replace the silicone rubber tube, vent the small hole wall plug on the side of the turbine housing, and clear the dirt.

Anonymous users2024-02-03The air release valve should be tested with a high-precision leak detector before leaving the factory. It is a prerequisite to ensure that every valve does not leak. As for the endurance test, it is tested by a special fatigue testing machine.
Generally, it refers to the release valve at high temperatures. Generally at 200-250 degrees. Repeated expansion and contraction at 30-1.2 million times without leakage is qualified.
It depends. Wuxi Yuezhou.

Anonymous users2024-02-02If the bypass valve is damaged, it will keep opening or closing. If it is left on all the time, it will cause insufficient turbine pressure, which in turn will lead to insufficient engine power. If it is turned off all the time, it will cause the steam turbine pressure to be too high, and in severe cases, it will lead to the steam turbine**.

The principle of a turbocharger is actually quite simple. A turbocharger consists of two parts, one is the exhaust turbine and the other is the compression turbine.
The exhaust turbine is connected to the exhaust manifold. When the engine reaches a certain speed, the exhaust has enough energy to drive the exhaust turbine to rotate. If the exhaust turbine starts rotating, the compression turbine will also start spinning, so that the compression turbine can compress the air body, blow the air body into the cylinder, so that the engine will become more powerful.
In order to avoid the turbine pressure being too high in the high-speed zone, all turbines have a bypass valve. When the turbine pressure is too high, the bypass valve will open and the exhaust gases will be discharged directly and quietly without passing through the turbine. Bypass valves protect the turbine.
If the bypass valve is damaged, it will affect the normal operation of the turbocharger.
If the bypass valve is damaged, the passenger must repair it immediately.
Is it normal for the supercharger to whistle.
It could be that there is a leak somewhere in the turbocharger line, and the rider should check it out after encountering this situation.
Many car engines use turbocharging technology, and the working principle of a turbocharged engine is actually quite simple.
A turbocharger consists of two parts, one is the exhaust turbine and the other is the compression turbine.
The exhaust turbine is connected to the exhaust manifold. When the engine reaches a certain speed, the exhaust gases have enough energy to drive the exhaust turbine to rotate, and the compression turbine will also start to spin.
When the compressor turbine rotates, the air is compressed and blown into the engine cylinders, increasing the volume of air entering the engine cylinders.
By increasing the amount of air entering the engine cylinders, the engine power can be increased.
A turbocharged engine can increase the amount of air entering the engine's cylinders without increasing the engine displacement.
Usually many veteran drivers say that turbocharged engines are fuel-efficient, but this statement is wrong. If the turbocharged engine of the same displacement is compared with the naturally aspirated engine, it is definitely the naturally aspirated engine that is more fuel-efficient.
However, turbocharged engines are also more powerful. How to measure the supercharger bypass valve to judge whether it is good or bad Is the supercharger whistle normal @2019
Compared with general car maintenance products and fuel-saving products, Novan Jinqing carbon fuel-saving pills have obvious market advantages, the most prominent of which are three points: comprehensive efficacy, is a multi-functional and all-effect product; Cost-effective, long-term use of considerable economic benefits; Safe and reliable, users can use it with confidence. From design to packaging, the products fully take into account the user's purchase characteristics and consumption concepts >>>More
It has to do with the oil you use, the air filter, the working environment (whether there is dust) and the quality of the supercharger, the most important thing is ventilation, if the supercharger is basically dead in a closed and high-temperature environment.
Summary. Qingling pickup truck is a domestic model, the standard engine is a domestic naturally aspirated engine, the official parameters are a maximum power of 116ps, a maximum torque of 145Nm. In addition, Qingling pickup also provides imported engines with a maximum power of 175ps and a maximum torque of 220Nm, providing consumers with a more powerful choice. >>>More
Because the turbocharger is often working at high speed and high temperature, the temperature of the exhaust gas turbine end of the turbocharger is about 600, and the supercharger rotor rotates at a high speed of 832 1040r min, so in order to ensure the normal operation of the supercharger, the following points should be paid attention to in use: >>>More
