High temperature gas control device for internal combustion engine

Abstract

The invention provides a high temperature gas control device for an internal combustion engine. The high temperature gas control device comprises an internal combustion engine body and a gas exhaust piping, and further comprises a temperature monitoring sensor, a controller, an actuator control valve, a high-pressure water circuit and a cooler liquid atomizing nozzle; the cooler liquid atomizing nozzle is arranged on the air exhaust piping, the input end of the cooler liquid atomizing nozzle is connected with the high-pressure water circuit, and a pressure cooling medium provided by the high-pressure water circuit is atomized through a spray hole of the cooler liquid atomizing nozzle to form a spray into the air exhaust piping; the actuator control valve is arranged at the input end of thehigh-pressure water circuit, and is connected with the controller through a signal line, and the controller is also connected with the temperature monitoring sensor through the signal line; and the temperature monitoring sensor is arranged on the air exhaust piping. According to the high temperature gas control device for the internal combustion engine, by reducing the temperature in the air exhaust piping, heat radiation energy is further controlled, the peripheral surface temperature of the internal combustion engine is reduced, the working reliability of the internal combustion engine andperipheral devices in a working process can be effectively improved, at the same time, the peripheral size of a power device can be reduced, and the integration degree of the power device is improved.

Description

technical field [0001] The invention belongs to the technical field of development of internal combustion engines, and in particular relates to a high-temperature gas control device for internal combustion engines. Background technique [0002] As a thermal power conversion device, the engine converts the chemical energy of the fuel into thermal energy and pushes the mechanical parts to do work. During the energy conversion process, about 40% is converted into effective work, and the remaining 60% is consumed by heat energy, exhaust, friction, etc., resulting in internal combustion engine The body temperature rises, especially the exhaust energy tends to be higher. Due to the high-load and high-power use of internal combustion engine devices, the temperature of their outer surfaces will rise, especially the exhaust temperature will reach 700°C or even higher, forming large energy heat radiation to soften the peripheral protective cover and lightweight new materials destroy....
