Road vehicles - Diesel engines - Screw-in injector, type 22
Specifies dimensional requirements for the mounting of injectors in diesel engines. The location of the fuel inlet is not defined since it varies with the particular application. Applies to the complete screw-in injector of type 22. A figure illustrates the shape and reference quantities of concern.

La présente Norme internationale spécifie les caractéristiques dimensionnelles nécessaires au montage d'injecteurs dans les moteurs diesel. L'orientation de la tubulure d'arrivée de combustible n'est pas définie car elle varie selon le cas d'emploi. La présente Norme internationale s'applique à l'injecteur complet vissé de type 22. NOTE - Cet injecteur complet a une fonction équivalente à celle des porte-injecteurs vissés des types 20 et 21 spécifiés dans l'ISO 7026 et équipés avec des injecteurs à jet axial de taille «S», types B et C, tels que spécifiés dans l'ISO 2697.

Overview
ISO 8356:1984 is an international standard that specifies the dimensional requirements for the mounting of screw-in injectors, specifically type 22, used in diesel engines for road vehicles. Developed by ISO Technical Committee ISO/TC 22, this standard ensures compatibility and interchangeability of screw-in injectors, promoting consistent performance and ease of maintenance across different manufacturers and diesel engine models.
This standard focuses on the complete screw-in injector assembly, emphasizing mechanical fit rather than fuel inlet location, which varies by application. ISO 8356:1984 provides essential guidelines for automotive engineers, manufacturers, and quality assurance teams involved in diesel engine fuel injection systems.
Key Topics
- Scope: Covers dimensional specifications for mounting screw-in injectors of type 22 in diesel engines for road vehicles.
- Injector Compatibility: Equates type 22 injectors with screw-in injection nozzle holders types 20 and 21 (per ISO 7026), used with "S" size injection nozzles types B and C (ISO 2697).
- Dimensional Requirements: Defines critical dimensions such as thread size (M14 x 1.25), hexagon size (14 h13 across flats), injector body lengths, and tolerances to ensure proper fit and sealing.
- Tolerances and Fit: Recommends thread engagement depths and clearance values to prevent interference with engine components, ensure sealing reliability, and facilitate proper cooling of the nozzle.
- Illustrative Figures and Tables: Includes a figure demonstrating the injector shape and reference points, and a table specifying the exact measurements and tolerance limits in millimeters.
- Excluded Aspects: Does not define fuel inlet location to accommodate variation across different engine designs.
Applications
- Diesel Engine Manufacturing: Ensures standardized mounting interfaces for screw-in injectors in diesel engines used in road vehicles.
- Injector Production: Provides manufacturers with precise dimensions and tolerances to produce injectors that fit universally into compliant engine heads.
- Maintenance and Repairs: Assists automotive service providers in selecting compatible replacement injectors that will fit correctly without re-machining or adjustments.
- Component Compatibility: Facilitates interchangeability between different injector types and nozzle holders that meet related ISO standards-improving supply chain efficiency.
- Quality Control: Enables inspection and verification of injector dimensions to maintain adherence to international standards for reliability and safety.

Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of
national standards bodies (IS0 member bodies). The work of preparing International
Standards is normally carried out through IS0 technical committees. Every member
body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, govern-
mental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the IS0 Council. They are approved in accordance with IS0 procedures requiring at
least 75 % approval by the member bodies voting.
International Standard IS0 8356 was prepared by Technical Committee ISO/TC 22,
Road vehicles.
