1、山東裝載機http://www.jmkey.cn/單體泵故障，檢查各缸的排氣溫度，若某一缸的溫度異常，往往說明單體泵有問題，檢查燃油歧管油壓，在滿負荷是應，如果油壓低于，更換燃油濾清器，如果油壓仍然太低，檢查輸油泵及其旁通閥，并檢查燃油壓力調節閥。
Shandong Loader single pump failure, check the exhaust temperature of each cylinder, if a cylinder temperature anomalies, often described monomer pump problem, check the fuel manifold hydraulic pressure is to be at full capacity, if the oil pressure falls below replace fuel filter, if the oil pressure is still too low, check the fuel pump and the bypass valve and check the fuel pressure regulator valve.

2、山東裝載機柴油質量差，柴油中有水或柴油粘度太低，詢問發動機使用柴油情況和水分，沉淀物的情況，如果柴油質量差，則放掉燃油箱、燃油管和燃油歧管內的燃油，更換燃油濾清器，在燃油箱中裝入干凈的合格柴油，用手油泵給系統注油并趕走空氣。
Shandong loaders poor quality diesel fuel, diesel oil in the water or diesel oil viscosity is too low, ask about the case of diesel engines and water, sediment, if diesel fuel quality is poor, then let go of the fuel tank, fuel lines and fuel within the fuel pipe manifolds, replace the fuel filter, into a clean diesel fuel in the fuel tank qualified, hand pump and oiling off air to the system.

3、山東裝載機燃油溫度太高，檢查輸油泵吸油口的柴油溫度。進氣管漏氣：檢查進氣管壓力，太低則檢查空氣濾清器，進氣管有無漏氣。
Shandong Loader Fuel temperature is too high, check the pump suction port diesel temperature. Intake manifold leak: Check the intake manifold pressure, too low, check the air filter, intake manifold for leaks.

4、山東裝載機燃油設置不正確，調整最大燃油設置至規范值，氣門間隙不正確：檢查和調整氣門間隙。
Shandong Loader Fuel is not set correctly, adjust the maximum value of the fuel is set to specification, valve clearance is incorrect: Check and adjust the valve clearance.

5、山東裝載機http://www.jmkey.cn/噴油正時不對，檢查和調整噴油正時，冷器氣路或水路受堵：測量進氣壓力，和規范值比較，增壓器效率低：檢查增壓器的積炭和間隙。
Shandong loaders injection timing is wrong, check and adjust the injection timing, cooler air passage or waterway is blocked: measuring the inlet pressure, and regulate the value of the relatively low efficiency turbocharger: Check turbocharger coke and clearance.
