The QSK23 uses a high pressure injection (HPI) Cummins PT fully electronic fuel system. The HPIPT fuel system consists of the G Drive Governor Control System (GCS) controller, which is intended to be mounted on the engine control panel outside the generator. Quantum Control has a specific fuel system board to interface with the HPI-PT fuel system and offers an engine protection package, electrical control design and full power as Control’s advantages to provide greater flexibility and a cost-effective alternative.
The CTT (Cummins Turbo Technology) HX82 turbo uses exhaust energy with greater efficiency to improve emissions and fuel consumption.
Charge Air Cooling – The QSK23 engine requires the use of an air-to-air heat exchanger or charge air cooler (CAC) to reduce intake manifold temperatures and meet low emissions requirements.
1. The injector is equivalent to a solenoid valve.
2. When the power is turned on, the electromagnetic coil generates electromagnetic force, the armature and the needle valve are sucked up, the fuel injector is opened, and the gasoline is sprayed into the intake port or intake pipe through the nozzle hole.
3. When the power is off, the electromagnetic force disappears, the armature and needle valve close the nozzle hole under the action of the return spring, and the injector stops injecting fuel.
4. The power-on and power-off of the injector is controlled by the electronic control unit with electric pulses.
5. The fuel injection quantity is determined by the electric pulse width. Pulse width = fuel injection duration = fuel injection amount.
6. Generally, the needle valve lift is about 0.1mm, and the fuel injection duration is in the range of 2~10ms.
The full range of injectors and related products are mainly used in commercial vehicles, construction machinery, mining equipment, marine power and generator sets, etc.
