①15 minutes power. The maximum effective power to make the engine run continuously for 15 minutes. The power indicator is specified to meet the mechanical requirements and have good overload and acceleration performance in a short period of time.
② 1 hour power. The maximum effective power that allows the internal combustion engine to run continuously for 1 hour. This power indicator is designed to meet certain power reserve requirements to meet the mechanical requirements of sudden load.
③12 hours energized. The maximum effective power that allows the internal combustion engine to run continuously for 12 hours. This is to meet the mechanical requirements of continuous operation in 12 hours - power indicator. Usually 12-hour power is also called rated power, and the power of the internal combustion engine is usually referred to that power.
④Endurance. Allows the maximum effective power of the internal combustion engine to run continuously for a long time. This should meet the power indicator specified by the mechanical requirements of long-term continuous operation??? Usually lasting power is 90% of the 12-hour power. Dongguan generator rental manufacturers believe that each internal combustion engine has two of the above four power, and according to its use and characteristics on the nameplate marked their corresponding speed.
2. Thermal efficiency
Equals the effective power of the thermal energy as a percentage of the thermal energy generated by the fuel consumed. It indicates the degree of effective fuel utilization, the thermal efficiency of diesel engines and gasoline engines is 20% to 40%.
3. Mechanical efficiency
The effective power of the internal combustion engine and the ratio of the indicated power. It indicates the power loss of each system within the internal combustion engine, expressed in η, the mechanical efficiency of diesel and gasoline engines in the following range: 0.78?0.85 for the non-boosted type, 0.80?0.92 for the boosted type.
Dongguan generator rental manufacturers to tell you the power of diesel generators.
Internal combustion engine per unit of time to complete the mechanical work, in kilowatts, the power is divided into the indicated power and effective power. Generally speaking, the internal combustion engine power is the effective power, which means that the internal combustion engine from the crankshaft outward, the net power output. In order to make the internal combustion engine operate reliably for a long time, the national standards specify the power of the internal combustion engine as above.
