Fault of Poor Contact in The Starting Circuit of Diesel Generators

The starting circuit of the diesel generator has poor contact. Although various instruments are normal, the diesel generator cannot start. Here are some examples:

power generation

Fault phenomenon: A Deutz F2L513 air-cooled diesel generator was originally starting normally, but after a system maintenance work, the diesel engine could not start. Pressing the start switch, the starter basically did not start.

Fault diagnosis: It was initially suspected that the battery was out of charge. Due to on-site operations, there was no professional charger available, so power was taken from another device using a grounding method. The power of this device is also a Fl2 port 13 air-cooled diesel engine, which is starting and charging. However, after connecting the wires, the diesel generator still cannot start, and after turning on the start switch, the starter still does not turn. At this point, the operator of the equipment believes that there is a problem with the maintenance personnel's maintenance, which may be due to improper adjustment of a certain position, causing the diesel engine to malfunction and fail to start.

Troubleshooting: In order to find the cause, the maintenance personnel conducted a comprehensive and careful inspection of the diesel generator and did not find any abnormalities. When using a pry bar to move the crankshaft of the diesel engine, it feels flexible and there is no jamming phenomenon. After careful investigation, it was found that the voltage of the voltmeter on the dashboard, whether connected or not, is only 22V, which cannot meet the starting voltage requirements; And the voltage when connected and not connected is the same, indicating that the electrical energy from the other vehicle has not been transmitted after being connected. Therefore, it was decided to connect the grounding wire directly to the connector behind the switch, and when the diesel engine was restarted for power generation, it immediately started successfully.

Fault description: Although the diesel engine and starting system appear to be working properly, starting the diesel engine may also be difficult if there are virtual connections or poor connections in the circuit.

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. The f

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
