Fuel consumption rate

Fuel consumption rate, it is the diesel engine per kilowatt-hour consumption of fuel A in g / (kWh). The fuel consumption rate per kilowatt-hour in an indicator power meter is called the indicative fuel consumption rate, and the fuel consumption rate per kilowatt hour in an effective power meter is called the effective fuel consumption rate. The former indicates the indicator of diesel engine economy. The latter indicates the economic efficiency of a certain engine. The fuel consumption rate referred to in the diesel engine product description refers to the effective fuel consumption rate. The fuel consumption rate referred to in the diesel engine product description refers to the effective fuel consumption rate. After measuring torque me and rotational speed n, as well as fuel consumption per hour TGT (kg/h) and effective power Pe, the effective fuel consumption rate ge is obtained by the following formula.

 

ge=Gt/Pe*10^3[g/(kW.h)]

 

The range of ge [g / (kW.h)] for diesel engines is as follows:

 

High speed diesel engine  

ge=212~235

 

Low-speed diesel

ge=169~190

lubricating oil consumption


The consumption of oil consumption per kilowatt-hour in a diesel engine is called the skid consumption rate in g / (kW h).

 

The g number of oil consumption per kilowatt-hour in a diesel engine is called the skid consumption rate in g / (kW h). Diesel engine lubricating oil is used continuously in the engine, the main reasons for its consumption are: when the diesel engine is in operation, the lubricating oil enters the combustion chamber through the piston or is burned by the air valve pipe flow in the gas cylinder, and the unburned oil is discharged with the exhaust gas. In addition, a portion of the lubricating oil due to atomization or evaporation in the crankcase by the crankcase vent. Diesel engine oil consumption rate is generally 0. 0. 5-4g/ (kW.h).
