Abstract

The invention relates to an integrated type commercial electronic control diesel engine starting, stopping and auxiliary braking system and method. The system comprises an integrated starter electricity generator device, a back power take-off flywheel housing, an air discharge type engine brake device, an ECU and an air discharge butterfly valve; the integrated starter electricity generator device is installed on the back power take-off flywheel housing and is meshed with a flywheel through a gear, the air discharge type engine brake device is installed in a rocker arm chamber, the air discharge butterfly valve is installed in an overall vehicle air exhaust pipe, the ECU is installed on an engine and is further connected with a vehicle speed sensor, an engine rotating speed sensor, a clutch state sensor, a speed changing box gear sensor, an accelerator position sensor and a temperature sensor. According to the integrated type commercial electronic control diesel engine starting, stopping and auxiliary braking system and method, the integrated starter electricity generator device is adopted, the engine manufacturing cost is reduced, and the starting capacity is high; the engine auxiliary braking function can be further achieved, the travelling safety is improved, the overall vehicle brake shoe abrasion is reduced, and the overall vehicle using cost of a user is reduced.

Description

technical field [0001] The invention relates to energy-saving control of a commercial electronically controlled diesel engine, in particular to an integrated commercial electronically controlled diesel engine start-stop and auxiliary braking system and method. Background technique [0002] With the rapid development of society, global resources are becoming increasingly scarce, and environmental problems are becoming more and more severe. Energy conservation and emission reduction has become an important research topic in the current society. In the field of automotive energy, the use of engine start-stop technology to achieve energy saving and emission reduction, reduce unnecessary energy consumption and exhaust emissions, has been widely used in the field of passenger cars, while it is still in the field of commercial vehicles. blank. The purpose of the present invention is to solve this problem well, and on the premise of realizing energy saving and emission reduction, i...
