- DIESEL ENGINE - OPERATING PRINCIPLEAt first glance, a diesel engine almost does not differ from a conventional gasoline engine - the same cylinders, pistons, connecting rods. The main and fundamental differences are in the way the fuel-air mixture is formed and ignited. In carburetor and conventional injection engines, the mixture is
- Signs and causes of malfunctioning diesel injectorsA malfunction of diesel injectors can usually be detected by the driver himself or the operator of the equipment where this type of engine is installed. It is necessary to pay attention to the operation of the engine.The first and main signs of a malfunction of diesel injectors.- Periodic interrupti
- Piston and connecting rod assyToday we will look at the procedure for removing the piston and connecting rod assembly.First you need to turn the crankshaft so that the piston is just below the carbon deposit zone, which is located above the piston ring travel zone. To remove carbon deposits, use an abrasive block, part number 38
- Fuel system of Cummins ISBe, ISLe, ISB, QSB enginesCummins injection pump ISBe, ISLe, ISB,QSB engines with front or rear timing gears.After replacing the fuel pump actuator, remeasure the fuel pump flow.If it is out of specification, replace the fuel pump. Connect the high pressure fuel line to both the fuel pump and the fuel pump actuator connector
- Cummins engine cylinder linerBefore removing a Cummins engine cylinder liner , an initial check should be made to determine if they can be reused. What is such a check?Check the inside of the sleeves for cracks, abrasions or gouges, and for deep vertical scratches that can be felt with a fingernail.It is necessary to check the
- The device and principle of operation of the fuel pumpThe fuel pump is designed to supply fuel from the tank to the car engine. It provides a uniform dosage and a constant pressure necessary for the correct operation of the motor. In the automotive industry, several types of pumps are used, which differ not only in design, but also in the type of drive
- The principle of operation of a mechanical nozzleThe principle of operation of the power supply system of a diesel engine with a mechanically controlled injector is as follows. To a high pressure fuel pump (fuel pump) is supplied fuel from a fuel tank . The booster pump is responsible for the supply, which creates a low pressure required to pump d
- ENGINE LUBRICATION SYSTEMThe engine contains a large number of parts rubbing against each other, they are all metal, and they all need lubrication, because they heat up and, as a result, can jam. Therefore, the engine has a lubrication system: with channels (lines), with a sump and with an oil pump. A simplified diagram of
