The oil pan is the lower half of the crankcase, also known as the lower crankcase. The function is to close the crankcase as the shell of the oil storage tank, prevent impurities from entering, and collect and store the lubricating oil flowing back from the friction surface of the diesel engine, dissipate some heat, and prevent the oxidation of lubricating oil. It can be manufactured by CNC engraving, Sand Casting, transparent acrylic(PMMA/PC) 3D Printing.

Second, it is necessary to regularly check whether the amount of oil in the fuel injection pump oil pool and its quality meet the requirements.

Each time before starting the diesel generator should check the amount of oil in the injection pump and its quality (except for the injection pump that is forced to be lubricated by the engine), to ensure that the amount of oil is sufficient and the quality is good, if the oil is deteriorated due to mixed with water or diesel, the light will cause the early wear of the plunger and the oil outlet valve, resulting in insufficient power of the diesel engine and difficult to start. In severe cases, it will cause corrosion and rust of the plunger and the oil outlet valve. Due to leakage in the oil pump, poor operation of the oil outlet valve, wear of the tappet and shell of the oil pump, and damage of the sealing ring, the diesel oil will leak into the oil pool and dilute the oil, so it should be replaced in time according to the quality of the oil, and the oil pool should be thoroughly cleaned when replaced, and the impurities such as mud at the bottom of the oil pool will be removed, otherwise the oil will deteriorate in a short time. The amount of oil can not be too much or too little, too much fuel in the governor, easy to lead to the diesel engine "flying", too little fuel will make poor lubrication, should be based on the oil ruler or oil plane screw. In addition, when the diesel engine is not used for a long time, be sure to check whether there is water, diesel and other impurities in the oil pump oil pool, if there is to be replaced immediately, otherwise due to long-term storage, water is easy to make the plunger, the oil valve coupling parts rust and die.
