Transversely-arranged engine, an oil pan and automobile

Abstract

The invention discloses a transversely-arranged engine, an oil pan and an automobile. The transversely-arranged engine comprises an exhaust pipe, the oil pan and a heat exchanger, wherein the outer surface of the oil pan is provided with a recessed part for allowing the exhaust pipe to pass through, the heat exchanger is positioned in the recessed part, and is used for sleeving the exhaust pipe, and the heat exchanger communicates with the exhaust pipe. According to the engine, the oil pan and the automobile, the heat exchanger is located in the recessed part and is not arranged at a chassis of the automobile, so that the structure of the chassis does not need to be modified to accommodate the heat exchanger; and for different types of the heat exchangers, only the outer surface structureof the oil pan needs to be modified, the modification cost is low compared with the modification of the chassis structure.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a transverse engine, an oil pan and an automobile. Background technique [0002] The vehicle warm-up process significantly affects the fuel consumption and emission levels of the vehicle. As the fuel consumption and emission regulations continue to become stricter, more and more OEMs have begun to pay attention to the improvement of the thermal efficiency of the powertrain. Engine exhaust accounts for about 1 / 3 of the energy of all fuel oil. Therefore, recovering exhaust heat for powertrain warm-up is of great significance to energy saving and emission reduction. [0003] refer to figure 1 , At present, a heat exchanger 4 is set on the automobile 1 as an exhaust heat recovery device, and the heat exchanger 4 is sleeved on the outer peripheral surface of the exhaust pipe 3 . The exhaust gas discharged from the engine 2 flows into the exhaust pipe 3, passes through the heat e...

AI Technical Summary

Problems solved by technology

Therefore, in the prior art, it is generally necessary to modify the car chassis structure to accommodate the heat exchanger, and the cost of car chassis structure modification is high.

At the same time, in the prior art, the heat exchanger 4 is far away from the engine 2, so a longer heat exchange medium pipeline needs to be added, and the cooling system of the original machine needs to be greatly changed.
