Diesel Generator Tech

The water temperature gauge is used to measure the temperature of the cooling water at the outlet pipe of the diesel generator's cylinder head and is an important accessory of the unit. This gauge can promptly reflect the water temperature of the cooling system and help understand the temperature of the cooling water when the diesel generator set is operating, enabling the diesel generator set to work at a normal temperature. The water temperature gauge can intuitively display the temperature of the water in the engine water tank, ensuring that the engine operates within an appropriate temperature range. Both excessively high and low water temperatures can affect the engine's performance. The water temperature gauge assembly consists of a sensor, a sensing wire, and a dial. The sensor is installed on the outlet pipe of the cylinder head, and the dial is installed on the instrument panel, with the two connected by a sensing wire. It is most ideal for the cooling water temperatu...

It is very important to know how to correctly start Cummins engine under cold weather. In this way, it not only helps prolong the engine’s service life and also keeps the generator set run smoothly. Take a few time to read this article, and then you will learn a lot. Cold Weather Starting  ( Note:   A water jacket heater is recommended for stand-by  generator set  applications installed in a cold climate.)   Preheater The glow plug system supplies heat to the cylinders so that compression temperatures are sufficient to ignite the fuel. To aid in starting the genset engine when the temperature is 50 °F[10.0°C] or below, an intake air preheater is available. Preheater equipment consists of a hand-priming pump to pump fuel into the intake manifold, and a switch to turn on the glow plug which is electrically heated by the battery. Fuel burns in the intake manifold and heats the intake air. Warning :   Do not use vapor in conjunction with the preheater. To do so...

Cummins diesel generator sets sometimes experience shooting during operation. At this time, we need to investigate the cause and specific solutions? Below, Dingbo Power Generation Equipment will be introduced in detail to everyone. The  Cummins diesel generator set  experienced severe afterburning in the diesel engine, causing the mixture to enter the exhaust pipe and continue to burn when the exhaust valve was opened, producing an explosive sound. During the intake stroke of a diesel engine, pure air enters the cylinder. It only begins to inject fuel towards the end of the compression stroke, and small droplets of fuel, after certain preparation, reach the ignition condition and burn on their own. Fuel droplets diffuse while burning; This is the diffusion combustion method of the Cummins diesel generator set diesel engine. Injecting early, before compression ignition, too much combustible mixture is formed. When these mixtures burn simultaneously during ignition, it can cause...

  If your machine has experienced the following five phenomena, then it needs to be overhauled. Our company can provide regular maintenance services for major, medium, and minor repairs of generator sets, and professional technical personnel can solve all machine faults for you, protecting your machine! Our Dingbo Power Generation Equipment specializes in the production of various types of generator sets, including small generator sets, imported generator sets, heavy oil   generator sets , etc. Please visit our website for details: The generator set has the following five situations: 1. The diesel engine is weak in operation, with a significant decrease and instability in rotation after acceleration, sudden sound changes, and black smoke emitted from the exhaust. 2. The diesel engine is difficult to start at room temperature, and there is a knocking sound from the crankshaft, bearings, connecting rods, bearings, and piston pins during operation. 3. When the temperature of a di...

With the increasing usage range and market demand of generator sets, the price of generators is also increasing. Can the investment in buying a generator set bring direct benefits to you. People have a common problem in their daily lives, what if the engine belt is loose? The generator belt noise in this situation is due to the operation of the generator belt driving many accessories, such as the generator, water pump, air conditioning compressor, steering pump, and so on. The   generator set   belt is a rubber product that grows over time, causing the belt to become loose in tension. This can cause the belt to "spin" and cause friction and noise with the accessories to be driven by the belt when the generator set is running. The heat generated by belt friction for a period of time will increase the viscosity of the rubber, so if it sounds for a while, it will not sound again. However, this situation must be promptly resolved. If the belt frequently rubs like this, it will ac...

The front oil seal of the crankshaft of the Cummins diesel generator set has oil leakage fault, so why does the oil seal oil leakage fault occur when the   Cummins diesel generator set   has not been running for a long time? In this article, Dingbo Power Generation Equipment will provide users with a brief analysis, and the specific content is as follows: The front oil seal of the crankshaft of the Cummins diesel generator set leaks oil, which is an oil seal fault. It is impossible to prevent oil leakage. Although the oil leakage rate is not high among the multiple oil seals of the Cummins diesel generator set engine, it is also very cheap, but there are many replacement and disassembly parts, and the labor cost is high, which is a typical minor ailment. So, the reasons for its failure have been analyzed by engineers, but there are only three points. (1) The aging oil seal of Cummins diesel generator set engine can only be a rubber product in Cummins diesel generator set engin...

This article mainly introduce how to adjust crosshead, injector and valves of Cummins diesel engine . If you are interested, take some times to read it carefully. Crosshead Adjustment Note: Crosshead adjustment should always be made before attempting to adjust the valves. 1. Loosen the locknut on the crosshead adjusting screw. Turn the adjusting screw out at least one turn. 2. Hold the crosshead down against its mating valve stem. Turn the adjusting screw back in until it touches the valve stem. Hold the adjusting screw in this position and tighten the locknut. 3. Tighten the adjusting screw locknut to 25 to 30 ft-lb [34 to 41 N*m] torque. Note:   When ST-669 Torque Wrench Adapter is used, tighten the locknut to 22 to 26 ft-lb [30 to 35 N*m] torque. 4. Check the clearance between the crosshead and valve spring retainer 1 and 2. Fig. 2–19 with a wire gauge. Tighten must be a minimum of 0.025 inch [0.64 mm] clearance. Fig.2–19. Valve spring retainer to crosshe...

In this article, we mainly talk about how to adjust injector and valve of Cummins diesel engines in a correct way. In addition, the engine temperature of the  generator set  is also required when adjusting the injector and valve.  Note:  At each “C” Maintenance Check, first perform all “A”, and “B” Checks in addition to those following: Adjust Injectors and Valves It is essential that the injectors and valves be in correct adjustment at all times for the engine to operate properly. One controls engine breathing; the other controls fuel delivery to the cylinders. Final operating adjustments must be made using correct values as stated. Cautions:   Be sure the injector and valve set markings, wherever located, are in proper alignment with the indicator mark. Engine Temperatures The following temperature conditions provide the necessary stabilization of engine components to allow for an accurate valve and injector adjustment. Cummins E...
