RF engine
RF-N engine
Since diesel engines do not have an ignition system, it is necessary to have a special tachometer. It is expensive, so its purchase does not justify itself.
1. Warm up the engine to operating temperature, engine temperature is not less than +80°С.
2. Turn off electrical consumers (radio, light).
3. Measure idle speed. Required values:
- RF: 825±5 rpm
- RF-N: 725±25 rpm.
4. If the idle speed differs from the required, loosen the lock nut and turn the idle speed screw to adjust the speed. Lock the screw after adjustment.
Attention! If the desired idle speed cannot be adjusted, visit a MAZDA or BOSCH dealer.
