How do I find BSFC?
The BSFC calculation (in metric units) Commonly BSFC is expressed in units of grams per kilowatt-hour (g/(kW⋅h)). The conversion factor is as follows: BSFC [g/(kW⋅h)] = BSFC [g/J] × (3.6 × 106)
How do you calculate BSFC mpg?
To calculate Fuel Consumption for a 400 hp Gas engine with a BSFC of .50 lbs/hp/hr:
- 400 hp x .50 = 200 lbs/hr.
- 200 lbs/hr / 6.25 lbs/gal = 32 gph.
- 400 hp x .0800 = 32 gph.
- 800 hp x .70 = 560 lbs/hr 560 lbs/hr / 6.59 lbs/gal = 84.98 gph.
- 800 * .106 = 84.80 gph.
What is BSFC value?
The BSFC value indicates how efficiently the engine converts fuel supplied into useful work.
What is BSFC and ISFC?
Brake-specific fuel consumption (bsfc) and indicated specific fuel consumption (isfc) is the specific fuel consumption on the basis of brake power (bp) and indicated power (IP) respectively.
What is BSFC Mcq?
Brake-specific fuel consumption (bsfc) and indicated specific fuel consumption (isfc) is the specific fuel consumption on the basis of brake power (bp) and indicated power (IP) respectively. s f c = F u e l c o n s u m p t i o n p e r u n i t t i m e p o w e r.
What is BSFC on dyno?
Once we have the lbs/hr of fuel consumed, this can be divided by observed horsepower to create what is called brake specific fuel consumption (BSFC) expressed in pounds of fuel per horsepower, per hour (lbs/hp/hr). This number is the amount of fuel used to make one horsepower for one hour at wide-open throttle (WOT).
How can I improve my BSFC?
Retarding intake opening will also benefit BSFC due to improved effective compression ratio, i.e. larger effective expansion to compression ratio. Advancing the exhaust valve opening will always result a higher BSFC and is not beneficial. Advancing the intake valve opening also improves BSFC.
What is the difference between SFC and BSFC?
BSFC is used to calculate and compare the fuel efficiency of a reciprocating engine, such as an internal combustion engine. There are different types of SFC: TSFC, thrust specific fuel consumption, and BSFC, brake specific fuel consumption, are two of the most common.
What is the formula for specific fuel consumption SFC )? Mcq?
The formula for specific fuel consumption is C=\frac{Q_f}{P} where Qf is fuel flow rate, P is power and C is specific fuel consumption.
What information we get in heat balance sheet?
Heat Balance Sheet is an account of heat supplied and heat utilized in various ways in the IC engine. Heat balance sheet is used to get necessary information regarding the performance of IC Engine. Heat balance sheet can be done on second basis or minute basis or hour basis.
Is low BSFC good?
It tells you how much fuel your engine will use per hour for each horsepower it makes. BSFC changes with engine load and rpm. A lower BSFC value is MORE efficient. Higher BSFC numbers are LESS efficient.
Why does BSFC decrease with load?
The main reason for reduction in BSFC with load is the conversion efficiency of the fuel. At higher loads, the turbulence and incylinder temperature inside the combustion chamber will be high which helps in the atomization and proper mixing of fuel resulting in higher combustion efficiency.
