What is BSFC in engines?
Brake-specific fuel consumption (BSFC) is a measure of the fuel efficiency of any prime mover that burns fuel and produces rotational, or shaft power. It is typically used for comparing the efficiency of internal combustion engines with a shaft output. It is the rate of fuel consumption divided by the power produced.
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 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.
Why does BSFC decrease with engine speed?
The decrease in BSFC is due to the better physical and chemical properties of fuel which assisted in improving combustion at low engine speeds. On the other hand, at high speeds, the friction heat losses occur and combustion deteriorates which increases the BSFC.
Is high BSFC good?
BSFC stands for Brake Specific Fuel Consumption. It tells you how much fuel your engine will use per hour for each horsepower it makes. A lower BSFC value is MORE efficient. Higher BSFC numbers are LESS efficient.
Why is BSFC important?
BSFC is a measure of the fuel efficiency of any engine that burns fuel and produces rotational power output. The BSFC value indicates how efficiently the engine converts fuel supplied into useful work. One of the main parameters used to determine the characteristics of biodiesel on BSFC is calorific value.
How much fuel does a 200hp outboard use?
| Select Yamaha Outboard Test Model | Stroke | Fuel consumption WOT |
|---|---|---|
| Yamaha 200 HP VMAX V6 | 4 stroke | 19.2 GPH |
| Yamaha 225 HP V6 | 4 stroke | 17.7 GPH |
| Yamaha 250 HP V6 | 4 stroke | 23.8 GPH |
| Yamaha 300 HP V6 | 4 stroke | 26.0 GPH |
What is SFC in diesel engine?
We then define specific fuel consumption (SFC) as the quantity of fuel burned in unit time required to produce a given engine output. SFC is a technical figure of merit that indicates how efficiently the engine converts fuel into power.
What is indicated power?
The indicated power of an I.C engine is the total power developed within the cylinder in one complete cycle neglecting any losses. It is the sum total of the brake power and the friction power of an engine. You can measure the indicated power of an engine by using the indicator diagram or power card diagram.
Why is BMEP important?
BMEP is a function of temperature of the gases in the cylinder. To increase the temperature you need to burn more fuel, thus making more heat. Or another way is to make better use of the existing fuel. Torque is a function of BMEP and displacement only.
What does low BSFC mean?
Definition & Description BSFC stands for Brake Specific Fuel Consumption. It tells you how much fuel your engine will use per hour for each horsepower it makes. A lower BSFC value is MORE efficient. Higher BSFC numbers are LESS efficient.
What does BSFC measure?
BSFC is the measurement of efficiency of fuel by the engine that combusts the fuel air mixture and produces the rotational motion of the crankshaft. This is used for comparing the efficiency of the engine. BSFC is the ratio of the rate of fuel consumption and the effective power produced from the engine.
What does BCfE mean in natural gas?
Key Takeaways. Billions of cubic feet equivalent (BCFE) is a term used to understand how much earnings potential a natural gas producer may have. BCFE is a measure of the amount of natural gas reserves and is made in terms equivalent to the energy in a standardized amount of crude oil.
How long does it take to pump 1 billion CFE of natural gas?
Considering that the average natural gas well pumps roughly 250,000 – 350,000 cubic feet equivalent per day, it would take one well roughly 3,000 days to pump one billion cubic feet equivalent of natural gas. Billions of cubic feet equivalent (BCFE) is a term used to understand how much earnings potential a natural gas producer may have.
How much should a company pay for gas mileage reimbursement?
In order to be eligible, the mileage costs must exceed 2% of the employee’s AGI (adjusted gross income). Unless employees drive a significant amount for business, the paperwork may be prohibitive. To manage gas mileage reimbursements, business should have a clear policy in writing.
What is MCF in natural gas?
Mcf is the conventional way to measure natural gas in the United States, which uses the imperial measuring system. In Europe, where the metric system is used, the abbreviation most commonly used is thousand of cubic meters or Mcm.
