The electronically controlled single pump is installed in the mounting hole on the 700 surface of the engine body. The fuel channel passes through the single pump into the oil return hole, and is sealed by the upper and lower sealing rings of the single pump to form a sealed low-pressure oil chamber. If the seal is not good, there will be two failure modes of internal leakage and external leakage of fuel. Among them, the "diesel engine single pump mounting hole oil leakage detection device" disclosed by the application number "CN201720350564.7" is also an increasingly mature technology. The diesel engine single pump mounting hole oil leakage detection device is usually installed at the mounting hole position of the diesel engine single pump. Specifically, this device will fit tightly on the mounting hole of the single pump to form a closed test environment.
