Problems solved by technology

[0003] However, after the turbocharger is used to pressurize the air, the temperature of the gas will increase significantly (up to 150°C and above)
Such a high temperature will significantly reduce the engine charge coefficient, affect its power performance, and cause a serious increase in the number of engine pre-ignition, which will not only affect its power performance, but also damage spark plugs, pistons, valves and other components, resulting in Engine scrapping

Embodiment Construction

[0033] The technical solutions herein will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used for explaining the text, rather than limiting the text.

[0034] In one embodiment of this application, as Figure 1-Figure 6 As shown, an intercooler 100 for an automobile is provided. The intercooler 100 is configured to include a shell 1, and the material of the shell 1 can be a common metal, such as steel or aluminum. The housing 1 is provided with a chamber 11 with a certain volume, and the shape of the chamber 11 can be set as a regular cylinder or rectangle. The housing 1 is also provided with an air inlet 12 and an air outlet 13. In order to fully cool the gas flowing through the chamber 11, that is, to increase the contact time or contact area with the cooling liquid in the intercooler 100, The distance between the air inlet 12 and the exh...

Abstract

The invention provides an intercooler and an engine waste gas control method and system. The intercooler comprises a shell provided with a cavity, wherein the shell is provided with a gas inlet and a gas outlet which are communicated with the cavity; a heat exchange component arranged between the gas inlet and the gas outlet, wherein the heat exchange component comprises a plurality of heat exchange assemblies arranged side by side, and the plurality of heat exchange assemblies divide the cavity into a plurality of gas flow channels communicated with the gas inlet and the gas outlet; and a control valve arranged between the gas inlet and the heat exchange component and arranged to adjust the total flow area of the plurality of gas flow channels, so that the problems of combustion deterioration, emission deterioration and even sudden flameout of an engine can be effectively avoided, and the intercooler can have better heat exchange efficiency.

Description

technical field [0001] This article relates to but not limited to the technical field of vehicles, and in particular relates to an intercooler, an engine exhaust gas control method and a control system. Background technique [0002] With the continuous increase of car ownership, the regulations on vehicle displacement are becoming more and more stringent. In order to meet the needs of small engine displacement and high power, automobile manufacturers generally adopt supercharging technology. Among them, exhaust gas turbocharging technology is currently the most used technology in passenger cars, and it is also one of the most mature technologies. [0003] However, supercharging the air with an obsolete turbocharger increases the temperature of the gas significantly (up to 150°C and above). Such a high temperature will significantly reduce the charge coefficient of the engine, affect its power performance, and cause a serious increase in the number of premature combustion of...
