The Inspection of Hydraulic Hose
The oil hose is a channel connecting the common rail to the electronically controlled injector. It should have sufficient fuel flow to reduce the pressure drop as the fuel flows, minimize pressure fluctuations in the high-pressure piping system, and be able to withstand the impact of the high-pressure fuel, and the pressure in the common rail can be rapidly established upon start-up.
“High pressure” means that the fuel injection system pressure is three times that of traditional diesel engines, up to 200MPa (the traditional diesel fuel injection pressure is 60-70 MPa).
Large and good atomization, full combustion, so as to improve the power, and finally achieve the purpose of fuel saving.
The length of the oil hose in each cylinder should be as equal as possible so that each injector in the diesel engine has the same injection pressure, thus reducing the deviation of fuel injection volume between each cylinder in the engine. Each oil pipe shall be as short as possible to minimize pressure loss from common rail to injector.
