Cause of cylinder head cracking of Cummins diesel generator set In winter, the temperature is low, Cummins generator cylinder head is very easy to break, so the following methods hope to help you! What causes cylinder head of Cummins diesel generator cranking? 1.Add cooling water after starting. After the diesel engine is started, the temperature in Cummins generator rises immediately. If cooling water is used at this time, the cylinder block and cylinder head will be cooled rapidly, and cracks will occur due to cold shrinkage. 2.After shutdown, cooling water was not discharged. The water in the machine freezes into ice, the volume increases, and the cylinder block and cylinder head crack. 3.During the operation of the generator set, if the cooling water is short or the temperature of the boiler opening machine in the water tank is too high, the cooling water will be used. Excessive cold shrinkage of the cylinder block and cylinder head can also cause cracking. 4....

Piston is the main moving part of diesel engine, which is one of the important components of the combustion chamber of diesel engine. The piston, cylinder head and cylinder sleeve constitute the combustion chamber of diesel engine, which bears the gas force and transmits it to the crankshaft through piston pin and side bar, so as to make the crankshaft rotate and output power. At the same time, in the process of compression, it also bears the thrust of the side bar. During the use of  diesel generator set piston , what faults maybe occur? And How to deal with them? In the process of using diesel generator set, the position of piston easy to wear is ring groove, followed by skirt and pin seat hole. 1.Wear of piston ring groove The piston ring moves in the ring groove, so that the piston ring groove is subject to the maximum wear in the height direction, so that it becomes a ladder or trapezoid. The main reason of wear is the unit pressure of piston ring on the groove wall...
