It connects, the other end is connect with the fuel feeding general pipeline, and the compressed air hose is equipped with third valve, the compressed air hose and fuel feeding
Between the second valve and engine oil rail, described oil return pipe one end is connect with the pressure release tank import for the junction of general pipeline,
The other end is connect with the fuel feeding general pipeline, and the oil return pipe is equipped with the 4th valve, and the oil return pipe is with the fuel feeding general pipeline's
Junction is described to connect for oil inlet pipe one end and pressure release tank outlet between the second valve and engine oil rail, another
End is connect with the fuel feeding general pipeline, described for being successively arranged oil feed pump and the 5th valve on oil inlet pipe, described for oil inlet pipe and institute
The junction of fuel feeding general pipeline is stated between the first valve and the second valve.
Further technical solution is that the 5th valve is check valve.
