Problems solved by technology

[0006] From the above operation process, it can be seen that the condensed water after the air intake intercooler of the supercharged diesel engine must be drained with the screw plug installed at the bottom of the intake pipe, which is troublesome to operate. easily damaged
These two ways of draining water are greatly affected by human factors, and it is difficult to guarantee the draining of water after the diesel engine is stopped or before starting. When the operator has no awareness of draining the condensed water or forgets to drain the condensed water, the condensed water will enter with the intake air when the diesel engine is started. Cylinder, because the temperature in the cylinder is low at this time, the water is not easy to evaporate, and part of the condensed water will enter the oil bottom along the cylinder liner wall, destroying the lubrication of the cylinder liner and diluting the engine oil, shortening the service life of the engine oil and increasing the use cost; if the water volume is too large, it will Cause major failures such as jacking or pulling cylinders; if you forget to close the drain hole when the diesel engine is running, air intake leakage will occur and affect the performance of the diesel engine

Abstract

The invention discloses an automatic condensed water drainage device of a charge air cooler, which extends into the lowest position of a gas inlet pipe of an internal combustion engine and comprises a piston outer sleeve, a piston body and an elastic device, wherein the piston outer sleeve is in a hollow structure, an opening is arranged at the upper end of the piston outer sleeve, a connecting bulge for connecting with the gas inlet pipe of the internal combustion engine is arranged at the lower part of the peripheral surface of the piston outer sleeve, a plurality of water inlet holes penetrating through the piston outer sleeve in the thickness direction are arranged in the positions which are adjacent to the connecting bulge, the water inlet holes are positioned above the connecting bulge and a plurality of water outlet holes penetrating through the piston outer sleeve in the thickness direction are arranged on the lower end surface of the piston outer sleeve; the piston body is arranged in the piston outer sleeve in a way of sliding up and down; and the elastic device is arranged between the piston body and the piston outer sleeve, when the elastic device is in a normal state, the piston body is positioned at the upper part of the piston outer sleeve. The automatic condensed water drainage device of the charge air cooler can reliably ensure that water drainage can be performed after shutdown of the internal combustion engine or before startup.

Description

technical field [0001] The invention relates to the technical field of internal combustion engine accessories, and in particular to an automatic drainage device for condensed water of an intercooler. Background technique [0002] The internal combustion engine is a heat engine that converts heat energy into mechanical energy by mixing liquid or gas fuel with air and directly inputting it into the high-pressure combustion chamber inside the cylinder for combustion and explosion to generate power. For supercharged internal combustion engines, the intercooler is an important component of the supercharging system. [0003] One of the reasons why a supercharged internal combustion engine has more power than a normal engine is that its ventilation efficiency is higher than that of a general internal combustion engine. When the air is pressurized, its temperature will increase significantly, and its density will also increase accordingly, and the intercooler just plays the role of...
