How does ambient temperature impact diesel generators?

According to international technical requirements, the operating ambient temperature of generators is generally set at 40 degrees Celsius, and all designs and powers are based on this ambient temperature. Indeed, for a generator, the ambient temperature must be the temperature of the generator inlet air. Since the generator runs on a diesel engine, the heat generated by the diesel engine will cause the entire space to exceed 40 degrees Celsius.

It is very important that the ambient temperature of the generator does not exceed 40 degrees Celsius during actual operation. If the actual ambient temperature exceeds 40 degrees Celsius, the generator should operate at reduced power. For ambient temperatures, if it is below 40 degrees Celsius, the generator power may be higher than the rated power.

What are the effects of too high or too low an inlet temperature on the mEFI engine of an automobile?

When the ambient air pressure decreases, the temperature increases and the relative humidity increases, the dry air drawn into the cylinder of the diesel engine will decrease and the power of the diesel engine will decrease. the power of the diesel engine will increase. Then, when the ambient temperature is too low, when the temperature of the cooling water in the water tank is too low, the temperature of the lubricating oil will drop accordingly. larger when the temperature is lower, and its fluidity will become worse. This will not only increase the wear of diesel generator set parts, but also cause the increased resistance to movement and increase the mechanical power loss and efficiency. the power of diesel generator set will decrease

Winter and summer should be divided into:

1. Summer

If the air temperature is too high. , it will expand easily, takingtoo much space, and the combustible mixture will be relatively fluid. There is no serious problem in the power of stratified combustion in the cylinder (an intake air temperature sensor is required). If it is too low the opposite will happen (outside the cylinder or if there is no stratified combustion it will decrease. If it is too low the mixture will be good but it will increase. However, it is impossible to have the intake air temperature too low in summer.)

2. Winter

If the air level is too high, the fuel will be well atomized, the mixture will be sufficient, and the power will be improved. If the air level is too low, the opposite will be true.

Car engine maintenance precautions:

1. Engine temperature is afraid of high temperatures rather than low temperatures:

Some people think that engine temperature is afraid ofhigh rather than low temperatures when driving. In fact, it is also very harmful when the engine temperature is low. The vehicle should be driven within the normal temperature specified in the vehicle instruction manual to ensure engine life. ?

2. The tighter the water pump fan belt, the better.

The tighter the belt, the better. If the belt is too tight, it will not only stretch or break, shortening the life of the belt, but also cause the generator shaft and water pump shaft to deform and bend. , and will cause early damage to bearings due to excessive tension. The sealing of automobile engine fan belt must meet technical requirements. Generally, the belt deviation during normal belt assembly is 10-15mm. ?

3. Blindly remove the thermostatt of the engine

If the thermostat is blindly removed due to the high temperature of the engine, the coolant can only circulate a lot and cannot adjust the cooling intensity, resulting in difficult backupIt ensures that the engine operates at a more suitable temperature, but often causes it to operate at low temperatures, resulting in reduced engine power, accelerated wear and increased fuel consumption. If the engine temperature is still high after repairing or replacing the engine thermostat, other parts of the cooling system should be inspected without removing the thermostat.
