Intercooler device for diesel engine

Abstract

The invention relates to an intercooler for a diesel engine, which comprises air intake covers 1, air discharge covers 2, intercooler cores 3, air intake cannulas 4 and air intake pipes 5, wherein the air intake covers 1, the air discharge covers 2, the intercooler cores 3 and the air intake cannulas 4 are positioned at the tops of the air intake pipes 5. The intercooler occupies a smaller volume and has a high integration degree; and the width of an engine can be effectively reduced without degrading the performance of the intercooler, so that the compactness of the engine or even a special vehicle can be improved.

Description

technical field [0001] The invention belongs to the technical field of diesel engines, and in particular relates to an intercooler device for diesel engines. Background technique [0002] Modern engines generally use superchargers to increase the pressure and density of fresh air entering the cylinders to increase engine power and reduce emissions. However, after the air passes through the supercharger, the temperature also rises, which to a large extent offsets the advantages brought about by the increase in pressure, resulting in the increase in engine power not reaching the expected target, and the maximum temperature in the cylinder is also greatly increased. , NOx and other pollutants generated by combustion increase, which is also not conducive to reducing emissions. In order to overcome the problem of air temperature increase after supercharging, modern engines generally install an intercooler after supercharging to reduce the air temperature to a reasonable range, f...

AI Technical Summary

Problems solved by technology

[0003] Generally, the intercooler device of a diesel engine includes an intake hood, an air outlet hood, a core, an intake heating device, an intercooler pipeline, etc. The number of such parts is large and scattered, and it occupies a large volume, resulting in different heights and widths of diesel engines. The degree of increase, the degree of integration of the whole machine is low, not compact

The general diesel engine intercooler device can meet the requirements of ordinary vehicles, but it cannot meet the needs of high compactness of special vehicle diesel engines

[0004] Special vehicles require high compactness in order to reduce the probability of being hit in battle and improve the battlefield survivability of special vehicles, which puts forward compactness requirements for the power system. The degree of integration is low, it is difficult to meet the needs of special vehicles
