Power meter description and power correction
Power coding
The power code on the power meter is defined in DIN ISO 3046-7/04.91.
L ISO power, its standard environmental conditions are: air temperature 25°C, intercooler filter medium temperature 25°C, atmospheric pressure 0.1mpa, air/relative humidity 30%.
L M ISO Output power of Marine main engine or auxiliary engine in unlimited navigation area, the standard environment conditions are: air temperature 45°C, medium temperature of intercooler filter 32°C, atmospheric pressure 0.1MPa, air/relative humidity 60%.
L C Continuous power
L N Net effective power
L UIC International Railway Union Regulation, UIC623-2VE/01.01.89.
According to the category specified in DIN ISO3046-1/04.91, the power used refers to the continuous effective power or the effective power with a time limit. The engine may have the following auxiliary equipment (as listed in Appendix A of DIN ISO3046-1/04.91)
Engine driven oil pump
L Engine driven cooling water pump for internal engine circulation
Engine driven fuel transfer pump
L Engine driven engine with rechargeable generator, no-load synchronous type
L The power in the power meter takes into account the intake stress loss and exhaust back pressure as well as the corresponding fuel temperature
