Idle Limit Time of Diesel Generator Set

 The idle state is the idling working state of the diesel generator set, that is to say, in this management working environment state, the diesel generator set does not need to carry the load, as long as we maintain the minimum speed required during the smooth operation.


 

The idle time of the diesel generator set should not be too long, and the diesel injection will reduce the atomization quality and accelerate the early wear of the cylinder wall. Because the quality of the atomization technology is mainly related to the injection pressure of the diesel generator set, the diameter of the injector and the speed of the camshaft.

Since the aperture size of different injectors remains unchanged, the quality of fuel atomization technology depends on the injection pressure and camshaft speed. The slower the camshaft speed is, the longer the fuel injection pressure will continue to rise, the worse the quality of the fuel through the atomization technology, and the camshaft speed changes with the working speed of the diesel engine. Too long idle speed will cause the diesel generator set diesel engine combustion temperature to be too low, the injection pressure is low, and the combustion is incomplete, which may cause carbon deposits to block the injection holes of the injector, piston rings or valves to be stuck.

In addition, if the cooling water temperature of the diesel generator set is too low, the unburned diesel will wash the oil film on the cylinder wall, the oil will be diluted, the various moving parts in the unit will not be able to lubricate normally, and the premature wear of the cylinder will pull cylinder. Poor oil supply, serious blow-by gas, and excessive contact stress of parts destroying the oil film are the main reasons for the diesel generator set to pull the cylinder.

After the diesel generator set is started, especially in winter, it should run at idle speed for 8~5min, and the standby oil pressure can reach 0.25mPa before allowing students to gradually develop and accelerate; when the water temperature is higher than 75C, the oil temperature is generally higher than 80C, and the oil pressure When it is significantly higher than 0.25mPa, it can start to work at full load. Under the influence of the cooling liquid temperature, lubricating oil temperature, fuel combustion temperature, etc., the engine can maintain a good working condition. 3-5 minutes is when the diesel generator set is idling before the engine shuts down, and then the supercharger speed is reduced until it stops.

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...
