For professional diesel generator manufacturers, all the parts on the diesel engine are well known, so I believe that many unit users do not know what the holes on the top of the diesel engine are for, what are their names, etc. Question, below, the power will introduce the various functional holes of the diesel engine one by one.   1. The drain hole at the lower end of the cooling water pump housing This hole is used to drain water leaking from the water seal between the impeller and casing. Make sure it is unblocked during use, otherwise the leaking water will not drain out and enter the bearing seat, thereby accelerating the damage of the bearing. the 2. The lubricating oil hole on the small end of the connecting rod and the bushing The function of this small hole is to make lubricating oil delivered to the small end of the connecting rod and its bushing in time to lubricate. If this hole is blocked, it will accelerate the wear of the bushing, reduce its service life, and cause the engine to run prematurely. to produce a knocking sound. the 3. Intake and exhaust holes on the radiator box When the engine is working, the rise in water temperature in the closed cooling system will vaporize the cooling water and generate high pressure, which will cause the radiator core tube to burst and leak water. And when the engine load becomes smaller or stops running, the water vapor in the cooling system will condense into water to lower its pressure, and the pressure difference may cause the core tube to be crushed, hindering the normal circulation of cooling water. For this reason, an air vapor valve is provided on the radiator cover, and a public air hole is arranged to communicate with the atmosphere. When the water temperature rises, water vapor is generated in the radiator, the steam valve opens, and the water vapor is discharged from the hole; when the water temperature drops, the pressure drops, the air valve opens, and the outside air enters the radiator through the hole, thus ensuring the radiator The internal pressure is stable. During use, ensure that this hole is unblocked and cannot be blocked, otherwise it will affect the heat dissipation performance of the radiator and engine. 4. The vent hole on the fuel tank cap In order to prevent the fuel in the fuel tank from splashing due to vibration, the escape of oil vapor and the entry of external dust, the fuel tank should be covered and sealed. However, when the oil level is lowered due to fuel consumption, a certain degree of vacuum will be formed in the fuel tank, causing the oil pump to lose its ability to absorb oil; in addition, when the temperature is high, the fuel evaporates, and the oil vapor will cause excessive pressure in the fuel tank. Both of these situations require automatic communication with the atmosphere when there is a pressure difference between the inside and outside of the fuel tank. For this reason, vent holes are provided on the fuel tank cap to balance the air pres...

Definition of bi-fuel generator: Bi-fuel generator set (English name: Bi-Fuel Generator Sets or Dual Fuel Generator Sets) is an innovative technology that can use a mixture of diesel and natural gas as fuel, and can also be used in the absence of natural gas In this case, run on diesel only. It has the excellent and reliable performance of a diesel unit, but also has the advantages of economy and environmental protection of a natural gas unit. When the load of the unit does not reach 30%, the unit is fully powered by diesel. When the load continues to increase, natural gas starts to be injected and mixed with diesel for combustion. As the load increases, the amount of natural gas input will increase accordingly.

A category of diesel engine electronic control technology. The main advantage of the high-pressure common rail system is that it can change the injection pressure and injection time in a wide range, and realize the electronic control of the diesel engine by considering the oil pressure generation process and the fuel injection control process separately. High-pressure common rail EFI technology refers to a fuel supply method that completely separates the generation of injection pressure from the injection process in a closed-loop system composed of a high-pressure oil pump, a pressure sensor and an electronic control unit (ECU). It uses a high-pressure oil pump to deliver high-pressure fuel to the public fuel supply pipe, and realizes precise control through the oil pressure in the public fuel supply pipe, so that the pressure of the high-pressure fuel pipe has nothing to do with the engine speed, which can greatly reduce the fuel supply pressure of the diesel engine. degree of change. Common Troubleshooting of High Pressure Common Rail System the 1. The diesel engine of the Synchronize Panel diesel generator cannot start the fault The diesel engine of the diesel generator is a compression ignition internal combustion engine. The smooth start of a diesel engine not only requires a large amount of fuel to be fully atomized and sprayed into the cylinder, but also requires the compressed air in the cylinder to have a certain temperature and pressure, so that the diesel can spontaneously ignite. Therefore, the diesel engine cannot start smoothly, and the reason is generally in the starting system, electronically controlled fuel system, intake and exhaust system or the matching clearance of the diesel engine. Customers can analyze and judge step by step according to the accompanying characteristics of the fault. For the whole vehicle whose starter is controlled by ECU, ECU first checks the neutral signal when starting, and then outputs a current to drive the starter relay. After the relay is connected, the battery drives the starter to start. Focus on checking the following items: neutral switch, starter relay, battery, parking switch. ① Check the position of the switch under the vehicle (should be in the disconnected state). ② Check whether the wiring of the transmission is intact, and try to use emergency start (press the ignition switch for more than 3 seconds). ③ Check whether the battery voltage is too low to drive the starter. ④Whether the starter relay and wiring are in good condition. ⑤ Check whether the starter is burned out. ⑥Whether the ignition switch and start switch are broken. 2. The rail pressure cannot be established The common rail system of diesel generators has high requirements on the fuel oil circuit, and the low pressure oil circuit (fuel tank, coarse filter, fine filter, oil return) and high pressure oil circuit (high pressure oil pump, common rail high pressure oil pipe, fuel injector) must be guaranteed Airtight. If there is ...

The water jacket heater The water jacket heater is a professional preheating device for diesel engine cooling water and lubricating oil. It is a necessary accessory device for diesel engine driving equipment when the working environment may be lower than 4°C. When the operating environment is likely to be lower than 4°C, the lubricating oil and cooling water of the engine may condense into a solid state during the starting stage, losing the effect of lubrication or cooling, thereby damaging the engine.
