JZ-CRN01 Common Rail Nozzel Pin
Standard function:
- Nozzle location should be as parallel to the airflow stream as possible.
- The nozzle angle in relation to the airflow stream is termed the "intercept angle."
- According to Strader, the intercept angle should "not be more than 45 degrees, although it can be less.
- Maintaining the proper intercept angle generally helps low-speed driveability and may also improve performance throughout the engine's operating band.
- The lower the inlet airspeed at idle, the more critical it is to maintain the ideal intercept angle. Idle vacuum correlates well with inlet airspeed-if you have 14-18 inches Hg of vacuum at idle as read on a vacuum gauge, maintaining the proper intercept angle is not as much of an issue in terms of driveability, although there still could be some emissions ramifications.
