AI Technical Summary

Benefits of technology

The inventor describes an improved system where an electronic controller (EC) module monitors the temperature inside the vehicle's tailpipe during operation. If there are any changes or fluctuations affecting this value indicating poor performance, it sends signals back to the EVAPC module which uses these values to calculate new parameters needed to improve fuel economy and reduce emissions levels. This allows automatic regulation of the emission level based on factors like ambient temperatures and driving conditions. Overall, the technology ensures efficient treatment of harmful gases released into the atmosphere while maintaining optimal combustion characteristics.

Problems solved by technology

This patented solution involves controlling the amount of oxygen entering an internal combustion engine by adjusting the position or size of certain components within it's structure. However, this approach requires many different types of equipment such as sensors and controls, making its overall process difficult to manage while also being expensive due to complexity involved.

Abstract

The invention provides an engine and an exhaust gas temperature control device for the engine. The exhaust gas temperature control device comprises a vehicle-mounted electronic control unit (ECU) module, an electronic control deflation valve supercharger comprising an actuator, and a temperature sensor arranged on an exhaust port of the engine. The vehicle-mounted ECU module is connected with a circuit of the actuator and a circuit of the temperature sensor to achieve data communication, obtains temperature data collected by the temperature sensor and generates a control instruction when the temperature data reach a preset exhaust temperature value in a MAP of the vehicle-mounted ECU module. The actuator controls the opening degree of the deflation valve according to the control instruction. Due to the facts that the exhaust gas temperature control device for the engine is provided with the temperature sensor and the ECU module is utilized for generating the control instruction to control the exhaust gas temperature of the engine, the structure is simple and the cost is low.
