Introduction of Cummins QSK60

The QSK60 engine is a V-type 16-cylinder four-stroke diesel engine developed by Cummins in order to cope with the current and future market competition and the worldwide emission regulations. It draws on some mature experience from the K50 engine. The displacement is 60 liters.

Metric unit design, early models meet EPATier1 emission requirements, adopt Cummins HPICELECT electronically controlled fuel system. Use FCD piston, higher fuel injection pressure, newly designed cylinder head, exhaust manifold and supercharger, and use low temperature medium Cold cooling system.

Working principle of Injector

The diesel fuel injection system atomizes the fuel and distributes it among the components that mix with the air in the combustion chamber.

The common rail injection fuel supply system consists of high pressure fuel pump, common fuel supply pipe, fuel injector, electronic control unit (ECU) and some pipeline pressure sensors. Each fuel injector in the system is connected to the common fuel supply through its own high pressure fuel pipe The pipes are connected, and the common fuel supply pipe plays a hydraulic pressure accumulating role for the injector. When working, the high-pressure fuel pump delivers fuel to the public fuel supply pipe at high pressure, and the high-pressure fuel pump, pressure sensor and ECU form a closed-loop operation to precisely control the oil pressure in the public fuel supply pipe, completely changing the oil supply pressure with the engine speed change. Phenomenon. Its main features are as follows:

1. The fuel injection timing is completely separated from the fuel metering, and the fuel injection pressure and the fuel injection process are controlled by the ECU in time.

2. The fuel injection pressure of each cylinder, the starting point and duration of fuel injection can be adjusted according to the working conditions of the engine, so as to pursue the best control point of fuel injection.

3. It can achieve very high fuel injection pressure and can realize pre-injection of diesel.

Porduct application

The full range of injectors and related products are mainly used in commercial vehicles, construction machinery, mining equipment, marine power and generator sets, etc.
