We know that when a diesel engine converts the energy contained in diesel (usually called LHV: Low Heat Value) into mechanical energy and outputs it through a flywheel, its efficiency is not high (usually about 40%). The reason is that most of the energy (about 60%) is converted into heat energy and taken away with […]

The fuel injection pump (also known as the high-pressure fuel pump) is the “heart” of the diesel engine and the most important component in the fuel supply system of the diesel engine. Its function is to increase the pressure of the diesel engine, and according to the requirements of the working process of the diesel […]

“Speed” refers to the phenomenon that the diesel engine speed is out of control and suddenly increases, exceeding the maximum allowable speed, accompanied by a loud noise. When the engine is “speeding”, if measures are not taken in time to control it, the engine may be damaged in a short period of time, even personal […]

What is the diesel engine’s rough work? It means that during the combustion process of the engine, the amount of diesel fuel burned is too much when the piston is near the top dead center, and the pressure rise rate is high, resulting in a crisp metal knocking sound when the engine is working, and […]

Normllay, we will meet the unstable engine speed when running diesel generator. “Traveling car” is a common name for unstable engine speed. When the engine is running, although the accelerator is fixed at a certain position, the engine speed still changes periodically in a large range, and it takes a long time to increase the […]

Diesel engines need regular maintenance in daily work, and maintenance mainly includes the following aspects, ITCPower needs to let you know. New diesel engine or diesel engine after overhaul should be run-in:After the new diesel engine was overhauled, parts such as cylinder liners, pistons, piston rings and bearing bushes were replaced. They did not undergo […]

The diesel engine is difficult to start, exhaust pipe emits a large amount of black smoke at the same time. This is the result of incomplete diesel combustion. It has many reasons for this phenomenon and we can check the different solutions for these different reasons. Here are the reasons why diesel engines meet the […]

When the diesel engine start difficult or unable to start, large amount of white smoke discharged from exhaust pipe, what should we do?  When the engine is started, the exhaust pipe emits a lot of white smoke, which is generally not a failure of the fuel supply system. What is the reason of exhausting the […]

Sometimes, diesel engine can turn when it being started but it will be in start failure at last. We also can not see the smoke from air cooled or water cooled diesel engine’s exhaust pipe. What is problem? How should we do to solve this? Let us tell you the more detailed contents.When the engine […]

Sometimes, we will meet the following the situation. The diesel engine was started, but its crankshaft is not rotating. Now, we will tell you how to check if the engine has such problem and if so, how to repair this problem. When the engine is started, under the condition that the starting system is intact, […]

What is the performance and how to solve when your diesel engine runs without idling. When the engine is without idling, it will has following situation.  When the throttle is placed in the idling position, the engine is turned off. When the throttle is increased slightly, the speed increases quickly, and it cannot run stably […]

In daily time, we are more familiar with gasoline engine, instead of diesel engine. However, diesel engine will be used more in more situation, such as construction, agricultural field, generating and so on. Why do people will choose diesel engine, instead of gasoline one? Firstly, lng life and economical durability. The speed of diesel engines […]
