Diesel generator sets in the use of the process, I believe that there are many users meet unit fuel consumption increased, but for the diesel engine generator were detected and found no problems. Maintenance also can not find out the specific reasons, in the end what factors affect the diesel generator set fuel consumption? Below we Ji'nan biogas generating set company small make up to introduce to you is the reason of the diesel engine fuel consumption:
Oil is generally through the gap between the piston ring and the ring groove, valve and the gap between the pipe into the combustion chamber. Its direct cause is the first piston ring in the vicinity of the top dead point due to the sharp drop in its movement speed, will be attached to the oil thrown into the combustion chamber. Therefore, the piston ring and piston clearance, the amount of oil scraping and scraping the piston ring, the pressure of the combustion chamber and the oil viscosity and oil consumption are closely related. If it is found that the amount of fuel consumption is to carry out the following checks, the general will be able to know where the problem, to solve the problem quickly.
diesel engine valve guide wear leads to extra loss of oil.
check the engine block and the engine block, the wheel side of the market, the back cover, cover and other connections are not in good condition, there is no loosening of the screws at the joints. If in the position of the frame for the oil leakage phenomenon, it is necessary to examine the shell oil, mainly to check with the wheel at the same side of the oil of the front end of the shell is generally because the base screw loosening, resulting in wheel in the triangle belt drive and protection of oil shell frame angle produces long-term rubbing a notch is formed, causing the phenomenon of oil leakage.
The engine wear the diesel engine cylinder liner formed longitudinal stretch marks, bore and piston side clearance exceeds the prescribed limit, guide the piston ring supporting force decreases, scraping oil dirty phenomenon. Or because the oil ring inside the inner supporting twisted spring break, the oil scraping net in combustion, makes the diesel engine is difficult to start, take the blue smoke exhaust pipes, respirator injection serious, resulting in additional oil consumption.
