brake-specific fuel consumption

brake-specific fuel consumption (BSFC)

The weight of fuel burned per hour to produce a given amount of brake horsepower in a reciprocating engine. Normally, BSFC is expressed in pounds of fuel burned per hour for each brake horsepower the engine develops.

Specific attention is paid to the changes in brake-specific fuel consumption (BSFC) and changes in brake-specific emissions.
The last section compares processed summary data including cycle-to-cycle variation, brake-specific fuel consumption and brake-specific emissions for the same selected operating points.
Additionally, we present plots of brake-specific fuel consumption, estimated peak in-cylinder pressure, and brake-specific emissions alongside each other.
Cycle to Cycle Variability, Brake-Specific Fuel Consumption and Emissions
It is seen that brake-specific fuel consumption decreases when the load is increased for all operations of diesel and Mahua biodiesel and their blends.
By identifying engines with greater than predicted brake-specific fuel consumption at a very early stage of degradation, remote equipment condition monitoring can help to reduce annual brake-specific fuel consumption.
In addition to minimizing exhaust emissions, the prechamber design, together with advanced engine electronics, contributes to brake-specific fuel consumption of 6,600 BTU/brake horsepower-hour.
