DENSO REMANUFACTURED DIESEL INJECTORS
“Top quality, reliable parts for a fraction of the cost of buying new”
The explosive growth of diesel-powered passenger and commercial vehicles in the Australian market, coupled with a combination of compromised fuel, has seen a spike in the number of diesel-powered vehicles turning up at service centres.
Denso Australia says its remanufacturing program offers economical repairs to these vehicles with a program that is supported by Denso’s extensive Australia-wide service network which is factory trained, fully equipped and authorised to diagnose and repair vehicles and fuel pumps with genuine Denso parts.
Stringent emission controls have resulted in higher injection pressures, around 2000 bar or 29,000psi and this has resulted in the injector design becoming much more complex, with finer tolerances.
Consequently, Denso says the repair process for these high-tech injectors has to also be stringently controlled and the genuine parts are required to ensure vehicle integrity. To ensure remanufactured units meet the specification, Denso says a strict remanufacturing process has to be followed.
- Sorting of Injector Cores
A pre-inspection test is conducted and damaged injectors are removed from the process. The injector core is sorted and unusable items are separated for recycling. The injectors are then scanned to produce a unique data sheet that follows the unit through the whole remanufacturing line as part of the quality-control process.
- Cleaning and Flushing
The injectors are capped and go into a high-pressure wash to ensure they are free from all external contaminants. They are then tested on Hartridge IFR-50s, which serves a dual purpose of flushing and pre-testing for obvious faults such as a high leak back value and/or solenoid faults.
- Dismantling the Injector
Parts are carefully inspected for damage and/or excessive wear. The reusable injector parts are then ultrasonically cleaned.
- Assembly Process
The assembly process is done in a positive-pressure cleanroom. The usable parts are then assembled with other Genuine Denso parts.
- Testing and Coding
Hartridge AVM2-PC test benches with factory supplied Denso controller and hardware are used to test and record the injector performance parameters at various flow rates, temperatures and pressures. An ID code which contains the injector performance characteristics is then affixed to the injectors that pass the bench test. The test data pertaining to each injector is kept on file for quality control purposes and warranty evaluation if it is required.
Denso says it ensures only genuine parts are utilised, whilst reusable parts undergo vigorous testing to ensure they meet Denso’s high quality standards.
