Intelligent system optimizing engine by means of processor, OBD and electronic control unit (ECU)

Abstract

The invention discloses an intelligent system optimizing an engine by means of a processor, an OBD and an electronic control unit (ECU). The intelligent system comprises the fuel processor, the ECU and the OBD which are installed at the front end of an oil inlet of the automobile engine. One end of the fuel processor is connected with an oil transporting pipe, and the other end of the fuel processor is connected with a fuel pump of the engine. The ECU and the OBD are connected through a CAN bus. After the fuel processor is installed, the working condition of the engine is changed, and parameters are read by the OBD and fed back to the ECU to be optimized. The ECU comprises an input processing circuit module, a microprocessor and an output processing circuit module. The OBD comprises a shell body, and a circuit board A, a circuit board B and a single chip computer are arranged in the shell body. The circuit board A and the circuit board B are electrically connected. The single chip computer is arranged on the circuit board A or the circuit board B. ECU parameters are read through the single chip computer; a module is built; various real time data of the engine of an original automobile are calculated and adjusted, and the adjusted data parameters are returned to the ECU; and the parameters are modified and replaced, therefore, the air-fuel ratio of the automobile engine is optimized, and fuel is fully burned. The power of the engine releases all the latent force, accordingly, the power output of the automobile is improved, the power output is smoother, the engine is protected, and oil consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted devices, in particular to an intelligent system for optimizing an engine by a processor, OBD and a vehicle computer. Background technique [0002] Since the 1980s, major automobile manufacturers in the United States, Japan, and Europe have begun to equip their EFI vehicles with OBD. The initial OBD did not have a self-test function. OBD-II, which is more advanced than OBD, was produced in the mid-1990s. The American Society of Automotive Engineers (SAE) formulated a set of standard specifications, requiring all automobile manufacturers to provide a unified diagnostic mode in accordance with the OBD-II standard. In the 20th century In the late 1990s, all cars entering the North American market were equipped with OBD according to the new standard. [0003] At present, the OBD system on the market can only read the data in the ECU driving computer, and cannot change the data of the ECU drivi...
