An automatic water discharge device for an intercooler

Abstract

The invention discloses an automatic water discharge device of an intercooler. The device comprises a valve body and a hollow valve element located in a valve cavity of the valve body, the valve bodyand the valve element form a valve structure, and connection and disconnection between an air inlet pipe and a water outlet hole are controlled; the water outlet hole is communicated with the atmosphere, a return spring is arranged on the valve element, and the cavity of the valve element is communicated with the air inlet pipe; the return spring is located in a spring cavity, and the spring cavity is isolated from the cavity of the valve element and is communicated with the atmosphere. When an internal combustion engine operates, the pressurization pressure acting force on the top of the valve element overcomes the pre-tightening force of the return spring, so that the valve structure closes a channel between a drainage channel and the water outlet hole; after the internal combustion engine is shut down, the pressure in the air inlet pipe is reduced to the ambient atmospheric pressure, the spring force enables the valve element to move upwards to open the channel between the drainagechannel and the water outlet hole, and condensed water is discharged out of an air inlet system. According to the device, frequent water discharge maintenance and operation are not needed, water discharge can be reliably ensured after the internal combustion engine is shut down or before the internal combustion engine is started, the internal condensed water of the intercooler is prevented from being accumulated, and normal use of an engine is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of internal combustion engines, and in particular relates to an automatic water discharge device for an intercooler. Background technique [0002] The internal combustion engine can increase the air density entering the cylinder by increasing the intake pressure (also known as boost pressure), so that the amount of air in the cylinder increases. This allows more fuel to be burned, resulting in a substantial increase in power, and also improves the economy of the internal combustion engine. After the internal combustion engine uses supercharging technology, it is possible to reintroduce the burned exhaust gas into the cylinder to reduce the harmful components in the exhaust gas without losing the power of the internal combustion engine. When the air in the intake system is compressed, its density will increase and its temperature will also increase, which will affect the cylinder charging efficiency, and wil...

Problems solved by technology

[0005] From the above operation process, it can be known that the condensed water after cooling in the intake air of the supercharged internal combustion engine must use tools to drain the water through the screw plug installed at the bottom of the intake pipe, which is troublesome to operate, and the thread of the intake pipe is easy damage

This water release method is greatly affected by human factors, and it is difficult to ensure that the water is released after the internal combustion engine is stopped or before starting.
