OBD (On-Board Diagnostics) based intelligent dynamic air treatment system

Abstract

The invention discloses an OBD (On-Board Diagnostics) based intelligent dynamic air treatment system. The system comprises an OBD communication module, an OBD data acquiring module and a fuel economizer, wherein the fuel economizer comprises a control panel, an ozone generating pipe and an air pump; a data processing single-chip microcomputer, a power interface, a signal indicating device, a high-voltage generating circuit, and a communication port corresponding to the OBD communication module are mounted on the control panel. According to the abovementioned technical scheme, the OBD based intelligent dynamic air treatment system has the advantages that the OBD communication module and the OBD data acquiring module are arranged in an energy-saving system; the communication port corresponding to the OBD communication module is arranged in the fuel economizer, so that the supplementing volume of ozone entering an engine cylinder can be adjusted in real time through the fuel economizer, and meanwhile, the circumstance that high content of ozone entering the cylinder interferes an oxygen content sensor of an automobile, resulting in inaccurate data of an electronic control unit of the automobile and more fuel waste of the fuel economizer, can be avoided. Therefore, the energy conservation and emission reduction effects can be achieved.

Description

technical field [0001] The invention relates to the field of automobile products, in particular to an OBD-based intelligent power air processing system. Background technique [0002] The modern automobile industry is developing rapidly, and more and more devices are installed on the automobile to facilitate people's use. Among them, OBD (On-BoardDiagnostic) on-board diagnostic system can monitor the running state of the engine and the working state of the exhaust gas after-treatment system at any time. Once it finds that the emission may exceed the standard, it will immediately issue a warning. When the system fails, the OBD system will store the failure information into the memory. Through standard diagnostic instruments and diagnostic interfaces, relevant information can be read in the form of fault codes. According to the prompt of the fault code, the maintenance personnel can quickly determine the nature and location of the fault. [0003] Most of the types of cars cu...
