What Is Supercharged Diesel Engine

1. In some supercharger models, in order to further improve its low-temperature starting performance, an intake air preheating device is also provided on the intake pipe of the diesel engine, and should be used correctly when starting at a low temperature.

2. After the diesel engine is started, it must be accelerated before the oil pressure rises, otherwise it may cause the supercharger bearing to burn out; especially when the diesel engine replaces the lubricating oil, cleans the supercharger, filters or replaces the filter element and stops for more than one week. After starting, in the idle state, loosen the oil inlet connector on the supercharger, tighten the oil after it overflows, and then idle for a few minutes before loading.

3. The diesel engine should avoid idling for a long time, otherwise it will easily cause the oil in the supercharger to leak into the compressor and cause the exhaust pipe to spray oil.

4. After the new diesel engine or the supercharger is replaced, the inlet pipe joint on the supercharger must be removed, and 50~60ml of oil should be added to prevent the supercharger bearing from being burnt out due to lack of oil during start-up.

5. Before the diesel engine stops, it must be idling for 2~3min. Under non-special circumstances, it is not allowed to stop suddenly to prevent the supercharger from overheating and causing the supercharger bearing to die.

6. Frequently, after using the diesel engine to stop, monitor whether there is any rubbing sound between the turbocharger impeller and the casing. If there is a rubbing sound, immediately disassemble the supercharger and check whether the bearing clearance is normal.

7. The sealing of the inlet and exhaust pipes of the supercharged diesel engine must be maintained, otherwise the performance of the diesel engine will be affected. Always check whether the tightening nut or bolt is loose, whether the hose clamp is clamped, and if necessary, replace the gasket.

Precautions for the use of diesel generators for supercharged diesel engines

The turbocharged diesel engine of the diesel generator set has the characteristics of improving the power of the unit, improving the specific power, improving the fuel economy, reducing the exhaust emission and noise, and thus is well received by the users. So what are the precautions in the use process?

1. Among the 135 basic diesel engines, the supercharged diesel engine designed before 1989, due to the low compression ratio, the starting performance is not satisfactory. In order to improve the starting performance, the turbocharged diesel engine that has been designed and improved since 1989 has taken measures to increase the compression ratio. In some supercharged models, in order to further improve its low temperature starting performance, an intake air preheating device is also provided on the intake pipe of the diesel engine.

2. The diesel engine should avoid idling for a long time, otherwise it will easily cause the supercharger oil to leak into the compressor and cause the exhaust pipe to spray oil.

3. After the diesel engine is started, it must be accelerated before the oil pressure rises, otherwise it may cause the supercharger bearing to burn out; especially when the diesel engine replaces the lubricating oil, cleans the supercharger, filters or replaces the filter element and stops for more than one week. After starting, in the idling state, loosen the oil inlet connector on the supercharger, tighten the oil after it overflows, and then idle for a few minutes before loading.

4. After the new diesel engine or the supercharger is replaced, the inlet pipe joint on the supercharger must be removed and the oil of 50-60m should be filled to prevent the supercharger bearing from being burnt due to lack of oil during starting.

5. Before the generator set stops, it needs to idle for 2-3 minutes. Under non-special circumstances, it is not allowed to stop suddenly to prevent the supercharger bearing from being killed due to overheating of the supercharger.

6. The sealing of the inlet and exhaust pipes of the supercharged diesel engine must be maintained, otherwise the performance of the diesel engine will be affected. Always check the tightening nut or bolt for looseness and the hose clamp is clamped. Replace the gasket if necessary.

7. Frequently, after using the diesel engine to stop, monitor whether there is any rubbing sound between the turbocharger impeller and the casing. If there is a rubbing sound, immediately disassemble the supercharger and check whether the bearing clearance is normal.

Diesel Generator Power Ratings: Standby vs Prime vs Continuous

Diesel generator sets are commonly used in a variety of sectors due to their dependable performance and high efficiency. They can be used for emergency power supply in the event of a power cut or used in places without connection to a power grid. When selecting a diesel generator for your home or business, you need to consider many factors, such as generator’s ratings. In this article, we’ll explain the three basic rating types - standby, prime, and continuous in diesel generators. ISO-8528-1:2018 defines basic generator set rating categories based on four operational categories: Emergency Standby Power (ESP), Prime Power (PRP), Continuous Power (COP) and Limited-Time Running Prime (LTP). Read on and learn the application of power ratings for engines used in generating sets. Standby Power Rating Standby Power(ESP) is used to supply emergency power when the external power supply is interrupted, such as power outages. Standby power rated generators can supply reliable electricity as t...

How to Connect A Diesel Generator to Your House?

Diesel generators are fuel-efficient and reliable, which can almost meet the power needs of any application. If you want to power the whole house during power shortages, it’s a good choice to choose a diesel generator set as the backup electricity supply. But how to connect a diesel generator to your house? Read on and you will find the answer. Options to connect a diesel generator to your home Keep in mind that never plug your generator directly into the mains, or it will cause back feeding, damage your appliances and be life-threatening for utility workers. Generally, you can choose to connect a generator to your house by using extension cords or a transfer switch. Understanding the difference between them is helpful for you to choose the right type. Extension cords Typically, extension cords are suitable for smaller diesel generators that used for short term. They require no installation and are cost-effective. If you need to power only some basic appliances such as...

What Should You Pay Attention to in Routine Maintenance of Diesel Generator Sets

In modern society, the stability of power supply is directly related to the operation efficiency of enterprises and people's quality of life. Diesel generators have become an indispensable backup power supply or main power source in various industries due to their high efficiency, durability and reliability. However, to ensure the smooth operation and optimal performance of the generator sets, regular maintenance is essential. Here is what you need to pay attention to in the routine maintenance of diesel generators. Keep your generator clean It’s important to keep the generator’s exterior and the generator room clean. Regularly remove any dirt, dust, or debris that may accumulate to on the generator’s surface. This is not only for the sake of beauty, but also for the smooth operation of the unit. Cleaning the generator’s exterior, air intake vents, exhaust outlets and generator room can effectively reduce the risk of generator overheating. In addition, check if the connection bol...
