Problems solved by technology

The EGR cooler is one of the key components of the exhaust gas recirculation system. The temperature of the exhaust gas is as high as 450°-700°. It needs to be cooled to a certain temperature range to fully exert the efficiency of the engine and minimize the emission of polluting gases. Influenced by other factors such as external temperature or season, it is difficult to control the temperature of the waste after cooling, and the superior effect of the EGR system is usually not fully exerted

Embodiment Construction

[0010] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0011] see figure 1 with figure 2 , an adjustable EGR waste cooling device. A cooler housing 1 is included, and a cooling water passage 1-1 is provided inside the cooler housing 1. The cooling water flows and passes through the cooling water passage 1-1, so as to lower the temperature of the high-temperature exhaust gas. A flow regulating valve 2 is installed on the cooler shell 1 through bolts, and the flow regulating valve 2 can control the opening of the cooling water circuit 1-1 inside the cooler shell 1, thereby controlling the flow of cooling water in the cooler, This controls the temperature of the exhaust gas after cooling. A temperature sensor 3 is installed on the cooler housing 1, and the temperature sensor 3 can convert the te...

Abstract

The present invention relates to an adjustable EGR waste cooling device, which includes a cooler housing, and the interior of the cooler housing has a cooling water channel, and is characterized in that it includes a flow regulating valve for controlling the opening of the cooling water channel, and the The flow regulating valve is installed on the cooling shell through threads, and a temperature sensor is installed on the cooler shell. The advantage is that the structure is simple, the cooling effect is good, and the cooling temperature of the exhaust gas can be controlled to improve the working performance of the EGR system.

Description

technical field [0001] The invention belongs to the technical field of engine waste cooling devices, in particular to an adjustable EGR waste cooling device. Background technique [0002] Exhaust Gas Recirculation (EGR), referred to as EGR, is a technology (method or method) that separates a part of the exhaust gas after combustion in a small internal combustion engine for automobiles, and introduces it into the intake side for recombustion. The main purpose is to reduce nitrogen oxides (NOx) in the exhaust gas and improve fuel consumption when sharing part of the load. It not only saves energy but also can effectively reduce waste emissions, so it is widely used in various engine systems. [0003] The exhaust gas in the exhaust gas recirculation system (EGR) is taken out from the exhaust pipe, cooled and then returned to the intake system of the engine, and enters the combustion chamber together with the mixed gas to lower the combustion temperature, reduce the generation ...
