9.0 Validation Requirements
9.1
General
This section outlines the validation requirements for the Multec 3.5 Fuel
Injector.
Validation is the process whereby the components and/or system are
evaluated through methods of testing, analysis, inspection, and/or
demonstration, to ensure that the component/system meets the specified
quality/reliability/durability goals and conforms to governmental
standards/requirements. The evaluation aims to verify the design,
manufacturing, and usage of the component/system.
The validation process could entail various types of evaluation based on
three levels
−
component, system, and vehicle. The injector DFMEA and
SFMEA should be used to pinpoint component/system strengths,
weaknesses, and possible failure modes, relative to actual vehicle
operation. Laboratory tests (arranged in a synergistic manner) can be used
in evaluating component and/or system conformance to QRD performance
goals and government standards. Delphi schedules and past experience,
along with field/road tests, are procedures used to provide validation data
for the component/system/vehicle relative to the “overall” package.
Evaluation of limit parts is crucial and will enhance comprehension of the
scope of injector performance under all conditions.
In some cases the injector is tested as a component of the fuel rail or
IAFM assembly.
9.2
Validation Tests
The validation tests to which Delphi-E&C has tested the Multec 3.5
injectors are listed below. A comprehensive validation plan may entail
performing the complete array of tests or a smaller selection of them,
based on the characteristics of the product and its intended application.
Consult Delphi-E&C for the appropriate requirements for each specific
application.
Note
: Except where noted, the part is to be mounted and connected per
application design requirements.
