Embodiment Construction

[0017] like figure 1 , figure 2 and image 3 A specific embodiment is shown, which includes a preheating pipe 2, the middle part of the preheating pipe 2 is in the oil pan 1, the two nozzles of the preheating pipe 2 are outside the oil pan 1, and the preheating pipe The two ends of 2 are sealed with the oil pan 1.

[0018] like figure 2 and image 3 As shown, both ends of the preheating pipe 2 are sealed and connected to the oil pan 1 through a ferrule-type straight-through body joint 3 , liner plate 4 , ferrule 5 , ferrule nut 6 , hex nut 7 and sealing ring 8 .

[0019] The ferrule-type straight-through body joint 3 is a pipe body with a block at the front end. The pipe hole surface at the rear end of the ferrule-type straight-through body joint 3 is a tapered surface. The outer surface of the ferrule-type straight-through body joint 3 is provided with threads. The straight-through body joint 3 is inserted on the side wall of the oil pan 1, and a sealing ring 8 is pro...

Abstract

The invention discloses a preheating system of an oil pan, comprising a preheating pipe, wherein the middle part of the preheating pipe is arranged in the oil pan; two pipe openings of the preheating pipe are arranged outside the oil pan; and two ends of the preheating pipe are connected with the oil pan in a sealing manner. In the invention, the preheating pipe is arranged in the oil pan; and by introducing hot water into the preheating pipe to preheat engine oil in the oil pan, the flowability of the engine oil can be improved and the cold start of an engine can be favored. Meanwhile, the preheating effect of the engine oil can be improved and the service life of the engine can be prolonged.

Description

technical field [0001] The invention relates to an engine oil heating system in an oil sump of a vehicle diesel engine. Background technique [0002] At present, HW mine car engines have difficulty in cold start at low temperature in winter, especially in the northern region. In response to this situation, many engines are equipped with devices to promote cold start, such as electric intake heating, flame preheating, body preheating or high-power starters, etc., which have a certain effect on improving cold start performance. But few consider it from the perspective of oil warm-up. In fact, when the outside temperature is as low as minus 20 or 30°C, the viscosity of the oil in the engine is very high, and its flow resistance is also very large, which has a great impact on the cold start performance of the engine. Moreover, under low temperature conditions, the lubricating effect of the engine oil on the engine is also very poor, and starting under such conditions for a lon...
