    P/N: 4914090 Replacement For Cummins Generator
    cummins generator speed controller 4914090

       The oil valve of the Cummins speed regulator is totally open and if the supercharger low-speed and with little air input, so it is difficult to ignite the fuel and can not completely ignite and have thick smoke displacement. It starry 400-1200rpm, It need 3-5 or 10-20 minutes to accelerate.

       It can easily start if we decrease the oil input. After it start, then increase the oil input, the speed and the diesel 
    generator temperature will increase gradually. Thus, the smoke displacement is Ww and the noise is soft. 

       The operation of and use of the set after start is same as other Cummins regulators. 

       This model is applied to the generator set matched with PT pump below 350kva, is the newly improved Cummins model with the new functions added as below:
