Yuchai Fuel Injector

Fuel injector matching for Yuchai diesel engines, quoted by engine nameplate and injector part number. Yuchai injectors follow the calibration, not the series: YC6A alone covers dozens of builds such as YC6A260-T302 and YC6A240-T300, and injector flow rating differs between them although the engine looks the same from outside. The four-cylinder YC4E and the six-cylinder YC6L share nothing here. We ask for the number stamped on an injector already fitted as well as the engine nameplate, because on a machine that has been repaired before, what is in the engine is often not what left the factory, and matching the running set matters more than matching the original specification. Injectors are supplied as a set for a reason: one new injector against five worn ones leaves the engine running unevenly and the new one doing more work than it should.
