GB/T 10826.3-2008Fuel injection equipment -- Vocabulary -- Part 3: Unit injectors (English PDF)

Foreword

GB/T 10826 "fuel injection means vocabulary" is divided into five parts.

--- Part 1. injection pump;

--- Part 2. injector;

--- Part 3. pump nozzle;

--- Part 4. high-pressure tubing and pipe end fittings;

--- Part 5. Common rail fuel injection device.

This section is GB/T Part of 310,826.

This part identical with ISO 7876-3:1991/Amd. 1.1993 "fuel injection means Vocabulary - Part 3. pump nozzle" (English Version).

This section is equivalent translation ISO 7876-3:1991/Amd. 1.1993. For ease of use, this section made the following editorial changes.

--- "National award criteria" be replaced by "this section";

--- Deleted international standards foreword;

--- This part of ISO 7876-3:1993 and other international standards adopted, where the country has been adopted as a standard by our standards on behalf of the for relevant international standards; our country has not been adopted as a standard, still direct use of international standards.

This portion instead of GB/T 10826-1989 for pump nozzle part of the "Diesel Fuel System terms" in the GB/T 10826-Compared to 1989, the main changes are as follows.

--- This section is amended as series of standards;

--- The original pump nozzle part of a larger technology content modifications.

This part is proposed by China Machinery Industry Federation.

This part of the National Standardization Technical Committee jet fuel centralized system.
