Guides to Clean and Check Exhaust Gas Turbocharger

Exhaust turbocharger is actually an air compressor that increases air intake through compressed air. It uses the inertial impulse of exhaust gas from the engine to push the turbine in the turbine chamber, the turbine drives the coaxial impeller, the impeller compressed the air from the air filter pipe to pressurize it into the cylinder. The increased air pressure and density entering the cylinder can burn more fuel, accordingly increase fuel amount and adjust engine speed, which can increase the output power of the engine. Structure: Exhaust gas turbocharger is mainly made up of turbine and compressor. Because the rotor of exhaust gas turbocharger has a high speed and the parts are more precise, so it is necessary to be familiar with the structural characteristics of the supercharger when using and maintaining it. Here, we will share the specific methods of cleaning and checking the exhaust gas turbocharger. Cleaning of  exhaust turbocharger 1. It is not allowed to cl

The Function of Turbocharging for Diesel Generator Set

What is the function of diesel engine turbocharging for diesel generator set The performance improvement of diesel generator set with exhaust air turbocharging is mainly shown in the following aspects: 1. Improve power performance After supercharging , the circulating air flow into the cylinder increases greatly. The circulating fuel supply increases accordingly, and the power of the diesel engine increase obviously. Turbocharging can increase the power of a diesel engine by 30% or more. At the same time, due to the increase of air burst pressure, friction loss is increased, but the effective power of diesel engine is increased more, so the mechanical efficiency of diesel engine is improved. 2. Improve economic performance The increase of mechanical efficiency after supercharging reduces the fuel consumption. The increase of intake pressure not only improves the scavenging process, but also makes the pump work become positive, and the fuel consumption

Cooling Tests for Volvo Diesel Engine

Cooling Tests  for Volvo Diesel Engine Cooling Tests, General Glossary A number of terms are used to define cooling system capacity. Maximum ambient temperature. The maximum ambient temperature the machine may be used in without exceeding the permissible water temperature. Δ t water (delta t) - the temperature differential between radiator inlet and outlet coolant. Δ t air - the temperature differential between radiator inlet and outlet air. Cooling capacity A cooling system installation's cooling capacity is often measured using a reference temperature for coolant boiling point called ATB (Air To Boil). The ATB temperature is defined as the ambient temperature at which the coolant attains its maximum permissible coolant temperature. AOT (Air On Temperature) refers to the maximum permissible coolant temperature after the Volvo engine  of diesel generator set .  It is defined as the temperature of the cooling air entering the charge air cooler.
