Описание (английский):

Specifies minimum requirements for hand-lever-operated testing and setting apparatus to perform certain tests on fuel injectors (having a spring-loaded nozzle valve actuated by fuel pressure) for diesel engines (requiring fuel delivery of up to 300 mm^3/(injection × cylinder)). These tests are detailed in ISO 8984-2 and are: nozzle opening pressure, chatter (atomization), spray pattern, seat leakage, back-leakage.

Overview

ISO 8984-1:1993 - Diesel engines - Testing of fuel injectors - Part 1: Hand-lever-operated testing and setting apparatus - defines the minimum requirements for hand‑lever‑operated equipment used to test and set diesel fuel injectors that have a spring‑loaded nozzle valve actuated by fuel pressure. It applies primarily to injectors for diesel engines requiring fuel delivery up to 300 mm³/(injection × cylinder). The actual test procedures are given in ISO 8984-2; this part establishes the apparatus, mounting, and validation conditions needed to get reproducible results.

Key topics and technical requirements

Scope and injector type: Covers injectors with spring‑loaded nozzle valves actuated by fuel pressure, up to the stated delivery rate.

Mandatory components: Pump and operating handle, inlet filter, fluid container, non‑return valve, ducts, isolating valve, pressure gauge, outlet connection, and a variable volume device (or equivalent compensation) are specified.

Mechanical and hydraulic parameters (as specified in the standard):

Operating handle stroke along line of action: 125 mm – 325 mm.
Specific delivery: 4.5 – 6 mm³ per mm of stroke (at atmospheric conditions).
Hydromechanical stiffness (isolating valve closed): ≥ 0.2 MPa/mm measured in the 5–35 MPa range.
Pressure gauge range: 0–40 MPa (400 bar) with defined accuracy, scaling and damping characteristics.
Outlet connection: to comply with ISO 2974 (M14 × 1.5 thread).

Internal volume elasticity and sealing: Detailed acceptance limits and a method for measuring trapped fluid elasticity (using a volume measuring device) to ensure consistent back‑leakage and leakage testing.

Validation and maintenance: Required tests include system tightness, pump plunger leakage, valve isolation leakage, gauge integrity, and internal volume elasticity (see clause 4 and Table 1). Annex A provides informative guidance on a volume micrometer device.

Applications and who uses it

Injector manufacturers - for production and setting of injectors to meet repeatable performance criteria.

Test laboratories and quality control departments - to verify injector function (nozzle opening pressure, chatter/atomization, spray pattern, seat leakage, back‑leakage) under standardized apparatus conditions.

Aftermarket and automotive service facilities - where hand‑lever injector testers are used for diagnostic and refurbishment tasks.

Equipment manufacturers - to design and certify hand‑lever‑operated injector testing apparatus that conforms to ISO requirements.
