Leaking fuel pump, the selection of location and control measures Fuel pump diesel engine is the "heart", and its role is to establish high-pressure diesel, and the work order and in accordance with the engine load variation, time, and quantity to be supplied to the diesel fuel pump, injected into the combustion chamber. Once an internal fuel pump leak, and even high-pressure and low Enveloper Oil Oil-linked, will start a diesel engine difficulties, unable to work, unable to operate normally. At the same time leaked diesel oil into the lubricants, so that lubricants diluted. Metamorphism, leading to an increased mechanical wear. A leaking fuel pump, the diagnostic methods Fuel pump leak occurred within the generally difficult to detect with the naked eye. If the engines start difficulties, power down, a row Oil endless air, and sometimes off automatically, or at the same time Shell Oil injection pump oil at the end of planar unusual increase in fuel pump can be diagnosed as internal leakage. 2 fuel pump leak in the main part
