How do I find my injector code?
The code is usually located on the injector head. DENSO Common Rail injectors – generally all require coding, although some very early versions may not. A typical code length is 16-24 alphanumeric characters depending on the vehicle make. The code is usually found on the injector connector.
What do the numbers mean on injectors?
Fuel Injectors are sized by their flow rate. Flow rate is a measurement of how much fuel can be delivered over time. It is listed in pounds per hour (lbs./hr.) or cubic centimeters per minute (cc/min.). The right size injector can supply enough fuel under full load conditions at an 80% duty cycle.
How do I know what size injectors to use?
Injector Math: How to Calculate Optimum Fuel Injector Size
- Step 1: Determine Horsepower.
- Step 2: Determine Approximate BSFC (Brake-Specific Fuel Consumption)
- Engine Type BSFC Using Gasoline.
- Step 3: Determine Your Safe Duty Cycle.
- Step 4: Calculate Your Optimum Injector Size.
- Step 5: Fine-Tune the Flow.
What is the code for a bad fuel injector?
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.
Is injector coding necessary?
Coding an injector is a vital part of the testing and repairing of injectors, and provides an essential connection between the physical injector firing events and the digital Electronic Control Unit (ECU) of the vehicle’s engine.
What are the two types of injectors?
There are basically two types of non-hydraulic common rail injectors — electromechanical solenoid base and Piezo. Piezos are typically found on newer applications, depending on the vehicle.
