This standard is a revision of GB10177-88 diesel engine fuel injection system product model compilation method 3. Compared with GB1017788, the main technical contents of this standard have changed as follows: the name of the standard has been changed. The "fuel injection system" in the original standard name has been changed to "fuel injection device" to be consistent with relevant standards such as GB10B26 (some fuel injection devices for oil engines). The product names and terminology are unified. The "fuel supply angle device" in the original standard has been changed to "fuel advance device", and the fuel pump installation method in the original standard has been changed to "end flange and arc separation combination installation method". The "arc bottom installation type" and "mid-bottom installation type" were changed to "end face flange installation type" and "bracket installation type" respectively to comply with the provisions of GB/T10B26. The model compilation method was simplified. The plunger type fuel injection model was deleted from the column oil volume maintenance belt (or required rotation) position code and the oil control angle (screw) direction, and the split type fuel injection pump was listed separately to avoid mis-coding the camshaft return code, etc. For example, the installation method of the synthetic fuel injection system was simplified to the following: The flange mounted type and bracket mounted type are consistent with the model compilation method of foreign oil pump nozzle manufacturers.
--In order to make the model compilation method more appropriate, considering that the technical parameters of the air film speed regulator are different from those of the mechanical speed regulator, the air film speed regulator is listed separately to be consistent with the foreign oil pump nozzle manufacturers. From the date of implementation of this standard, the original GB10177-8B is invalid. This standard was issued and regulated by the Technical Committee for Standardization of Oil Pump Nozzles of the Ministry of Machinery Industry. The winning bidders are: Beijing Weifu Jinning Co., Ltd. and the Oil and Gas Research Institute of the Ministry of Machinery Industry. The drafters of the bid are: Fan Kejie and Zheng Peitan. This standard was first issued in December 198 and revised for the first time in 1998. This standard was entrusted to the Oil and Gas Research Institute of the Ministry of Machinery Industry to interpret the scope of the People's Republic of China's Machinery Industry Standards for Diesel Engine Fuel Injection Equipment Product Model Compilation Method The standard specifies the fuel injection equipment for diesel engines and the fuel injection equipment for diesel engines. 2.2 General Principles
