Another portion of the engine plus oil port directly through the inside of the crankcase, it is judged diesel engine failure, but also has some unique.
① plus oil port black smoke. In the diesel engine is running, add oil port emitting blue smoke or black smoke, キセノンランプand hear Knocking sound description cylinder, piston and piston ring wear, with the gap increasing between the three, so the combustion chamber high temperature The high-pressure gas channeling into the crankcase, and emerge from the Canadian oil port;
② plus oil port white smoke. Diesel engine plus oil port failure phenomenon of white smoke to be good at screening, and can not simply be attributed to "boil water, fuel moisture content is just one of the reasons why white smoke. In winter, the leakage from the combustion chamber to the ecu チューニング crankcase portion of the gas, due to its temperature and ambient temperature difference between the larger, emerge from the plus oil port, showing the white mist, after the rise of the temperature to be a diesel engine, this white The smoke may disappear. In addition, shortly after the engine starts, the rhythm from the Canadian oil port emitting white smoke, which is burning ear "precursors. 車LEDライトThe eve of the "bush-burning due to the local dry friction plain bearings, so that the temperature of the bearing parts of a sharp rise, prompting the surrounding oil evaporation into the white mist particles discharged crankcase. Should immediately stop check, can not improvise, so as not to cause "axle" accident.
③ plus oil port out spray oil. Diesel engine operation, if you spray out the oil from the Canadian oil port, not only illustrate cylinder, badly worn piston, piston rings may have been broken, stuck, or the formation of a "cylinder". Produce high temperature and high pressure gas of the combustion chamber a serious phenomenon under exhaust, forcing oil from the Canadian oil mouth out spray Wherever such a situation, the power of the diesel engine will be significantly decreased, a sharp increase in fuel consumption, shall immediately for repairs.
④ hear abnormal noise from the Canadian oil port at. If you add the oil port hear a short "Dangdang" sound, and has the following characteristics: First, in the diesel engine suddenly accelerated from idle, the sound is more obvious and prominent; Second, the higher the speed, the greater the sound; Third, single cylinder oil off loud weakened or disappeared, you can judge the connecting rod bearing issue abnormal sound. Should check the connecting rod bearing clearance is too large, 自動車パーツthe connecting rod bolt is loose. Need to be described is the above method by adding oil port to determine fault, mainly for not installed a diesel engine of the crankcase ventilation means. If the engine is set crankshaft forced ventilation means to disassemble the associated piping, and can also be observed whether the crankcase blow-by gas.
