What do the numbers on injectors mean?
Fuel Injectors are sized by their flow rate. Flow rate is a measurement of how much fuel can be delivered over time. For example, a naturally aspirated, 300 hp engine (BSFC 0.5), with 8 injectors will need 23.4 lbs./hr. of fuel per injector at an 80% (0.8) duty cycle. (300 X 0.5) ÷ (8 X 0.8) = 23.4 lbs./hr.
What code does a bad fuel injector throw?
The most common fault codes associated with a clogged fuel injector are P0171 and P0174, which indicates the engine controller is seeing a lean condition. It is also possible to see fault codes for a rich condition if the injector is leaking or not atomizing correctly.
Do new fuel injectors need calibration?
the fuel injector is not necessarily to be calibrated, it can be replaced with an new one if it is damaged, one condition that users do not care how much money to be paid for replacing a new one.
How are injectors coded to the engine control unit?
Fitment of replacement injectors will require the new injectors to be coded to the engine control unit. Injector coding classification type Some earlier common rail injectors have no coding. And some Bosch and some Siemens/VDO injectors use a single code identification process for injectors called injector classification.
How are fuel delivery characteristics coded on a Dodge injector?
The fuel delivery characteristics are coded on each injector with a six digit alphanumeric correction code such as CA1YBL. The ECM uses this code to set a fuel delivery baseline for each injector. When a DT670001R injector is installed the injector’s code must be entered into the ECM or the engine operation will be affected.
What is the calibration code for a Ford injector?
This function is required by service centres when an Injector needs to be replaced, or there is a driveability problem. For 1.8 TDCi and 2.0 TDCi engines the each injector has a 16-digit calibration code stamped on the body. For 1.6 TDCi engines the each injector has an 8-digit calibration code stamped on the body.
Where do you find the calibration code on a common rail injector?
No products in the cart. Common rail injectors of all brands require coding of the unique calibration code (found on the injector) to the engine ECU. Below we have set out some examples of Denso, Bosch, Delphi and Siemens common rail injectors and where you can find the calibration codes for each brand.
