Abstract

The invention provides an electric control system and a method for an engine and an engine comprising the electric control system. The electric control system for the engine comprises a receiving unit for receiving indicating information representing one of the engine working modes, and a control unit for generating a control signal according to the indicating information to control the running state of the engine, wherein the control unit comprises a plurality of running state limiting modules for limiting at least one running parameter of the engine respectively; and each running state limiting module is provided with a preset startup / shutdown state corresponding to each engine working mode. Through the technical scheme of the invention, the fuel economy can be increased.

Description

technical field [0001] The invention relates to an engine, in particular to an engine electronic control system, an engine electronic control method and an engine including the electronic control system. Background technique [0002] Fuel economy is one of the big issues facing the automotive world. On the one hand, the automobile industry is faced with the requirements of laws and regulations related to environmental protection, requiring improved fuel economy to help save energy and reduce CO 2 , NO x and sulfur emissions, on the other hand, it is facing the challenge of high oil prices. Therefore, improving fuel economy is a consistent demand of the automotive industry as well as consumers. [0003] For vehicles with complex and changeable driving conditions, different loads and different road conditions put forward different requirements on the power of the engine. Usually, vehicle performance and fuel economy are difficult to have at the same time, because better po...
