An oil pan assembly

Abstract

The invention provides an oil pan assembly, which belongs to the technical field of oil pans. It solves the problem that the water in the engine oil cannot be removed during the short-distance start-stop process of the existing vehicle. The oil pan assembly includes an oil pan and an electric heating block at least partially arranged in the oil pan. The interior of the electric heating block has an air intake channel and an air outlet channel, an air inlet of the air intake channel and an exhaust port of the air outlet channel. They are all located in the oil pan. The oil pan assembly also includes a curved casing located outside the oil pan. There is a condensation channel inside the curved casing. One end of the condensation channel communicates with the intake channel, and the other end of the condensation channel It communicates with the air outlet passage, and an electric air pump connected with the condensation passage is arranged on the curved casing. The oil pan assembly can remove the moisture in the engine oil during the short-distance start-stop process of the vehicle.

Description

technical field [0001] The invention belongs to the technical field of crankcases and relates to an oil pan assembly. Background technique [0002] When the engine is working, there is a high-pressure combustible mixture and burned gas in the combustion chamber. These gases will more or less enter the crankcase through the gap between the piston group and the cylinder, and the gas that enters the crankcase is composed of water vapor. , exhaust gas and unburned fuel gas, etc., when the engine oil in the oil pan is at a low temperature, the water vapor liquefies and mixes with the engine oil, resulting in the dilution of the engine oil, resulting in emulsification of the engine oil and reducing the performance of the engine oil. It also accelerates the oxidation and deterioration of the oil. In addition, when the engine is used in a particularly cold environment, the water mixed in the oil will condense into ice cubes, causing serious problems such as blockage of the oil pump...

AI Technical Summary

Problems solved by technology

[0004] When the above-mentioned engine is running, the above-mentioned crankcase ventilation system can work normally. When the engine is turned off, the crankcase ventilation system will stop working. Therefore, when the working environment of the engine is below zero and the vehicle is moved for a short distance, the engine’s The time interval between starting and stopping is short, the electric heating device cannot fully heat the oil in the oil pan, and the water in the oil in the oil pan will not evaporate to form water vapor, even if the electric heating device continues to work after the engine is turned off, it will The oil in the oil pan is heated to evaporate the water in the oil to form water vapor. The water vapor is located in the crankcase. Since the crankcase ventilation system does not work when the engine is turned off, the water vapor in the crankcase cannot be discharged. The water vapor It remains in the crankcase all the time, and when the engine oil cools down, the water vapor liquefies to form water droplets and mixes with the engine oil, which cannot solve the problem of emulsification or freezing of the engine oil during short-distance maneuvering
