Failure Strategy of Crankshaft Position Sensor of Cummins Generator Set

The engine of the 290kW Cummins generator set adopts the Cummins patented PT fuel system, which enables the set to have higher reliability, durability, power and fuel economy while meeting environmental emissions. So do you know what its crankshaft position sensor failure strategy is?

(1) The concept of failure strategy. The so-called failure strategy is the operation mode of the electronically controlled diesel engine under the fault state. When the diesel engine is in the following conditions, the control strategy will enter the Limphome state.

1. The crankshaft position sensor is damaged or the signal circuit is open or short circuited.

2. The camshaft phase sensor is damaged or the signal circuit is open or short circuited.

3. The oil pressure sensor of the common rail is damaged or the circuit is open or short circuited.

4. The oil metering valve of the high-pressure oil pump is damaged or the drive circuit is open or short-circuited.

5. The electronic throttle sensor is damaged or the signal circuit is open or short-circuited.


(2) Crankshaft position sensor failure strategy. When the ECU judges that the crankshaft position sensor or the camshaft position sensor signal is faulty, the sensor is damaged or the signal circuit is damaged (open circuit or short circuit), the ECU takes the following measures:

1. Turn on the fault light.

2. Generate fault codes: P0008, P0340, P0341, P0335, P0336.

3. The diesel engine continues to work by relying on a single sensor.

4. There is no obvious influence on the power performance of diesel engine.

5. The starting time may be slightly longer than normal.

6. The throttle feels normal.

7. There is no obvious impact on operation, but fuel consumption and emissions may become worse.

What Is the Difference Between Electric Motor and Electric Generator

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and winding currents to generate force. In certain applications, such as in regenerative braking with traction motors, electric motors can be used in reverse as generators to recover energy that might otherwise be lost as heat and friction. An electric generator operates in the reverse direction, converting mechanical energy into electrical energy. Electric generator can be divided into various type, open type, silent type, trailer type, portable type and container type, etc. Electric generator is mainly composed of diesel engine & alternator. Electric generator set is mainly composed of engine, alternator, control module, and common base. Electric generator :- Electric generator is a type of machine which converts mechanical input (energy) into electrical output (

Engine Fault Code Messages - Volvo Penta Engine

Volvo Penta Engine Fault Code When a malfunction has occurred and the diagnostic system has generated one or more fault codes, these are read out differently depending on the equipment used. Please refer to “Fault code messages”. If the system indicates that a fault code has been set: 1 Cut engine speed to idle, or shut the Volvo engine off. 2 For DCU/DU Read the fault code from the display, please refer to Reading fault codes via the DCU or Reading fault codes via the DU. For CIU press the diagnostic button and read the fault code, by observing the flashing of the diagnostic lamp. Refer to Reading fault codes via the diagnostic lamp, CIU. 3 Look up the fault code in the Fault Code Register chapter and take the recommended measures. Reading fault codes via the DU (Display Unit) Depending on the severity of the fault the text, either WARNING! or ALARM STOP (a buzzer sounds) will be shown on the display 1 Press any button to come to the fault list.

Types of Diesel Engine and Application of Diesel Generator

This article will guide you to learn diesel engine types and important role of diesel generator. If you are interested, please keep reading.  What Are Diesel Engines? A type of internal combustion engine more accurately known as a compression ignition engine is designed to provide power by compressing the fuel at high temperature and significant pressure until it ignites. Diesel engines are either two-stroke or four-stroke .   ‘Stroke’ means the movement of the piston in the engine. Two-stroke This engine uses one stroke in each direction.   The first stroke being compression, which results in the ignition of the compressed fuel.   The return stroke brings new fuel into the cylinder. Four-stroke This engine has one compression stroke and one exhaust stroke and each one of those has a return stroke – hence, four-stroke. The compression stroke compresses the fuel/air mixture prior to ignition.   The exhaust stroke pushes the burnt gases out the exhaust. The
