How Isuzu Excavator Earth Moving RHF55 Turbo VB440031 CIES works:

  The turbocharger is mainly composed of a compressor and a turbine, which are connected by a drive shaft. The air inlet of the turbine is connected to the exhaust manifold, and the exhaust port is connected to the exhaust pipe; the air inlet of the compressor is connected to the air intake pipe. , the exhaust port is connected to the intake manifold.

   The turbine is impacted by the exhaust gas discharged from the engine to cause high-speed operation, and at the same time, the coaxial compressor is driven to operate at a high speed to force the compressed air into the cylinder.

   The advantage of an engine equipped with a turbocharger is that it can greatly increase the torque and power of the engine without increasing the engine displacement. Under the same displacement, the power of an engine equipped with a turbocharger is about 40% higher than that of an engine without a turbocharger, so turbochargers are now widely used.

  The maintenance of Isuzu Excavator Earth Moving RHF55 Turbo VB440031 CIES is to change the oil filter regularly, clean the turbine frequently, do not turn off the engine immediately, choose the correct oil and use the oil properly, etc. As an air compressor, the turbocharger can increase the liter power of the engine and improve the fuel economy, but daily maintenance is very important, otherwise the lag of Isuzu Excavator Earth Moving RHF55 Turbo VB440031 CIES will be more prominent.

Turbocharger maintenance method should pay attention to the following points:

1. Regularly change the oil filter: the consumption and lubricity of oil are the key points of turbocharging technology. Choosing the oil recommended by the original factory can reduce the lack of lubrication and heat dissipation of the floating turbine main shaft.

2. Frequent turbo cleaning: If the lubricating ability of the oil decreases, it will cause the turbocharger to be scrapped prematurely. Clean or replace the air filter on time to prevent dust and other impurities from entering the supercharger impeller rotating at high speed.

3. Do not turn off the flame immediately: After the running engine is suddenly stopped, the oil pressure is zero, the high temperature of the turbo part of the supercharger is transmitted to the middle, and the heat cannot be quickly taken away. If the temperature of the exhaust manifold is very high at this time, its heat It will be absorbed into the turbocharger housing, and the oil staying inside the supercharger will be boiled into carbon deposits.

4. Correct selection and rational use of oil: General turbocharged engines need to use fully synthetic oil, and the replacement cycle of oil is reasonably determined according to the conditions of use. Be sure to avoid using fake oil and oil that does not meet the requirements, otherwise it will cause abnormal wear or severe coking of the turbine, which will damage the supercharger.
