Abstract

The invention discloses a dual-fuel automobile airtightness and ventilation detection apparatus and a control method thereof. The detection apparatus is connected with air, a diagnosis interface of an automobile, and an air supply system of the whole automobile, the air supply system of the whole automobile includes a high pressure air supply system and a low pressure air supply system that are communicated through an air guide pipe, the air guide pipe is provided with a pressure-reducing valve electrically connected with the diagnosis interface, the high pressure air supply system includes an automobile charge valve, and the low pressure air supply system includes a combustion gas filter electrically connected with the diagnosis interface. The dual-fuel automobile airtightness and ventilation detection apparatus has the characteristics of high airtightness and ventilation detection precision, high intelligent degree, low artificial cost, simple operation, and high detection efficiency.

Description

technical field [0001] The invention relates to the technical field of dual-fuel vehicles, in particular to a dual-fuel vehicle air-tightness and air-permeability detection device with high detection accuracy and a control method thereof. Background technique [0002] With the rise of oil prices and the enhancement of environmental protection awareness, dual-fuel vehicles are becoming more and more popular among consumers, especially CNG dual-fuel vehicles with affordable prices and mature technologies have become the first choice for more families and rental operators. With the increase in demand for CNG vehicles, the original CNG vehicle gas air tightness testing equipment and testing beats cannot meet the needs of existing mass production, and cannot realize air permeability testing, and cannot provide consumers with safer and more reliable CNG vehicles. [0003] Chinese Patent Authorized Publication No.: CN202210018U, authorized public date on May 2, 2012, discloses a b...
