    Oil machine is mainly used method of exhaust gas turbocharger to increase its effective power. Turbocharger makes up for the naturally aspirated engine of some deficiencies, so that the work of the engine cylinder volume without changing the case of greatly increased output power, many projects are using this turbo machinery technology to improve engine power output and to improve the quality of the engine’s power ratio, achieving high performance machines.   1, the composition of the turbocharger and its function Diesel fuel in the cylinder by combustion for power, input the amount of fuel by the amount of inhaled air in the cylinder limit, the resulting power is also limited, if the engine’s operating performance has been at its best, can only further increase the output power compression more air into the cylinders to increase fuel consumption, improve combustion as a function of force. In the current technical conditions, the turbocharger is the only way for the efficiency of the diesel engine without changing the mechanical device to increase power output. Turbocharged diesel engine turbocharger is a key component of diesel engine power output increased 20% to 30%, 8% lower fuel consumption, exhaust smoke by 25% to 50% of harmful emissions are also significantly less toxic gases small. Therefore, the daily use of construction machinery, attention to the proper use of turbocharger to reduce the use and maintenance costs, reduce energy consumption, protecting the environment is important. Turbocharger is actually an air compressor to increase the intake air through the air, it mainly consists of two parts, turbine and compressor components. Turbine inlet chamber is connected with the exhaust manifold, exhaust port connected to the exhaust pipe; compressor inlet pipe and air filter connected to the exhaust port connected to the intake manifold; turbine wheel and compressor impeller, respectively, installed in the turbine room and the supercharger, the two rigid coaxial connection. Turbo diesel engine emissions using inertial momentum to drive the turbine room of the turbine, the turbine and driven coaxial impeller, the impeller pressure delivery pipe sent from the air filter the air, so that pressurized into the cylinder. Faster when the engine speed, the speed and the turbine exhaust gas speed is also faster synchronization, the impeller to compress more air into the cylinder, air pressure and density increase to burn more fuel, a corresponding increase in the amount of fuel and adjust the engine speed, increase engine power output. 2, the common failure analysis Turbo diesel engine into the exhaust manifold mounted on at high temperature, high pressure and high-speed operation of the working conditions, very poor working conditions, job requirements and relatively harsh, prone to failure in use. After the failure of the general performance of diesel engine power significantly decreased, black smoke, take too much blue smoke and oil consumption, abnormal turbocharger sound big noise. The main reason for poor lubrication failure, and accumulation of foreign substances into the fatigue damage. (1) Poor lubrication Refers to the turbocharger compressor impeller and turbine in the turbine rotor shaft bearings are not good lubrication, as well as damage to the rotor shaft and bearings, supercharger does not work. Mainly by the lack of poor lubrication oil, lubricating oil pipeline leaks and deterioration caused by other reasons. ? (2) the entry and accumulation of foreign substances Refers to the intake pipe in the dirt and exhaust pipe coke, dust, debris and other accumulation, if the intake pipe in the long term not to replace the air filter, intake manifold, the compressor impeller for long periods of cleaning will produce coke, into the air resistance increases so that the same turbine on the turbine, nozzle coking also have adverse consequences. In addition, the intake and exhaust system will also affect the joints leak turbochargers work.
