Main installing requirements of Diesel engine

1. Installation of the crankshaft During crankshaft installation, the main bearing bolts should be tightened from thrust gear(the third gear) to both ends in order, and in three steps: ① tighten to 60-80 N.m ② tighten to 160-180 N.m ③ tighten to 220-260 N.m During every time, the crankshaft should be rotated to check the mobility. It should be able to rotate freely after the final tightening.The axial clearance should be between 0.1 and 0.27 mm . 2.  Installations of the piston and the connecting rod When installing the piston rings, put the surfaces marked upward( the second positive twist ring inner fillet upward). During positioning the piston-connecting rod assembly into the cylinder bore, stagger the joints in turn. A nd put the arrow marked on the top surface of piston towards the front end of the engine. Remember spreading some clean oil before tightening connecting-rod bolts. T he tightening torque should be between 160-200N.m, and completed in three steps:...

Before purchasing, people offen ask what’s the difference between  diesel generator   and gasoline generator? As a professional manufacture, Jiangsu Starlight Electricity Equipments Co.,Ltd will tell you the difference between two of them. 1.   In-cylinder pressure object is different: The  gasoline generator  compresses the gasoline and air mixture during the compression stroke stage; The diesel generator compresses the air at the compression stroke stage. 2. Ignition is different: The gasoline generator relies on spark plugs; The diesel generator relies on atomized diesel to spray high pressure gas spontaneous combustion. 3. The mixture of fuel and air is different In the gasoline engine, fuel and air are combined in the carburetor and intake ducts; In the diesel engine, the mixing of diesel and air is carried out after the diesel is injected into the cylinder. 4. Use range is different Gasoline generators are generally used for ...

Operation of Yuchai diesel engine

Preparations before starting the diesel engine To make sure that the engine would run properly, the following steps should be done before starting the engine every time: ①  Check the oil level in the oil sump. The level should be within the upper and ower scale limits of the oil gauge. If the oil volume is not enough, add some oil as required. ②  Check the diesel fuel level in the fuel tank. add some fuel if necessary. ③  Check the coolant level, add some coolant if necessary. ④  Check if there is air in the fuel pipe. De-aerate fuel if there is air in the fuel pipe. ⑤  Check if electrical system works properly. ⑥  Check the ension of the driving belt. the rension should be moderate as required. ⑦  Perform all the technical maintenance as required.
