Specific fuel consumption (SFC) is a measure of the fuel efficiency of an engine design, typically expressed in units such as pounds of fuel per hour per horsepower (lb/hp·h) or kilograms of fuel per hour per kilowatt (kg/kW·h). It is calculated by dividing the rate of fuel flow (mass or volume) by the power output of the engine. For example, SFC can be calculated using the formula: SFC = Fuel Flow Rate (mass per time) / Power Output (power). A lower SFC indicates a more efficient engine, as it uses less fuel to produce a given amount of power.

What is fuel consumption of yanmar 850 kw diesel generator set?

The fuel consumption of a Yanmar 850 kW diesel generator set typically ranges from 180 to 210 liters per hour, depending on the load and operating conditions. Factors such as engine efficiency, load factors, and ambient temperature can influence this consumption rate. It's essential to refer to the specific model's technical documentation for precise consumption figures.


Effect of gearing ratio on fuel consumption?

Gear ratios will let the engine run at the speed and load at which it is most efficient, which is good for low fuel consumption and an exhaust that is as clean as possible.


Lube oil consumption of diesel engine?

Lube oil consumption depends on engine design and motor operating conditions. Dieselnet is a good source. Typical oil consumption values for pre-1980s engines were 0.46 g/kWh (0.34 g/bhp-hr; 0.25% of fuel consumption), pre-1990 engines ranged between 0.33-0.48 g/kWh (~0.15 - 0.20% of fuel consumption). A test on a number of 2002 heavy-duty and medium-duty engines in the US yielded an average of 0.22 g/kWh (0.1% of fuel consumption). Year 2007 heavy- and medium-duty engines consume on average 0.08 g/kWh (around 0.03% of fuel consumption)


Which calculator helps to calculate fuel consumption?

A pen and paper. Miles driven divided by gallons of fuel used gives you mpg.


How much fuel does a eighty kva diesel generator consume per hour for no load?

An 80 kVA diesel generator typically consumes around 1 to 2 liters of fuel per hour when running under no load. This consumption can vary based on factors such as the generator's efficiency, maintenance condition, and specific model. However, it's important to note that fuel consumption is generally higher under load conditions. Always refer to the manufacturer's specifications for more accurate figures.

What is thrust specific fuel consumption of turbo shaft?

There is no such thing as thrust specific fuel consumption of a turboshaft engine, as a turboshaft is designed to deliver mechanical power, not thrust. This mechanical power can be converted into electric power by a generator or converted into thrust by a propeller or rotor. Basically, a turboshaft uses jet technology but is an alternative to a piston engine. While thrust specific fuel consumption doesn't exist for a turboshaft, "brake specific fuel consumption" does. It measures the rate of flow of fuel required for a certain amount of power. For example, a specific fuel consumption of 0.2 lbs/h/hp means that for every horsepower the turboshaft produces, it burns 0.2 lbs of fuel each hour.


What is the fuel consumption formula for marine twin diesel engines?

The fuel consumption formula for marine twin diesel engines can be expressed as: [ \text{Fuel Consumption (g/h)} = \frac{\text{Power Output (kW)} \times \text{Specific Fuel Consumption (g/kWh)}}{2} ] In this formula, the power output represents the combined output of both engines, and the specific fuel consumption is the amount of fuel consumed per unit of power produced. The division by 2 accounts for the fact that there are two engines.


How do i calculate Specific lube oil consumption?

To calculate specific lube oil consumption, divide the total amount of lube oil consumed during a specific period by the total fuel consumed in the same period. The formula is: [ \text{Specific Lube Oil Consumption (SLOC)} = \frac{\text{Total Lube Oil Consumed (liters)}}{\text{Total Fuel Consumed (metric tons or liters)}} ] This will give you the lube oil consumption per unit of fuel, typically expressed in liters per metric ton or liters per liter of fuel consumed.


What is the formula to calculate specific fuel consumption of a man b and w engine?

The specific fuel consumption (SFC) of a marine diesel engine, such as a MAN B&W engine, is typically calculated using the formula: [ \text{SFC} = \frac{\text{Fuel flow rate (kg/h)}}{\text{Power output (kW)}} ] This formula provides the amount of fuel consumed per unit of power produced, allowing for the assessment of engine efficiency. It is commonly expressed in units like kg/kWh.


What do you mean by specific fuel consumpion?

Specific fuel consumption is an exact measure of how many pounds (or other measure of weight or volume) is used to produce each horsepower an engine produces. For example, if you have a diesel engine running at a certain speed that produces 10 HP while burning 4.5 lbs of fuel per hour, its specific fuel consumption is .45 lbs/HP.


What does fuel consumption mean?

Fuel consumption refers to the amount of fuel used by a vehicle or machinery over a specific distance or time period. It is typically measured in units such as miles per gallon (MPG) or liters per 100 kilometers (L/100 km). Fuel consumption is a key indicator of efficiency, impacting operating costs and environmental emissions. Lower fuel consumption often correlates with better fuel economy and reduced carbon footprint.


What is the fuel consumption on the cat 365 excavator?

The fuel consumption of the Caterpillar 365 excavator typically ranges from 8 to 12 gallons per hour, depending on factors such as operating conditions, load, and attachment use. This can vary based on the specific model and its configuration. For precise fuel consumption, it's best to consult the operator's manual or specifications provided by Caterpillar for the specific unit in question.

How do you calculate fuel consumption in diesel engine?

IT CAN BE CALCULATED THEORETICALLY & PRACTICALLY:- 1. theoretically--- For this you must know the SFC(specific fuel consumption) of the engine at the given load. for example(let us consider a diesel generator of 20 kw having SFC as 232 gm/kw-hr at 75% load) (20x0.75)x232 therefore Fuel consumption in ltrs/hr= =4.094ltr/hr 0.85x1000 here 0.75 is for 75% load 0.85 is density of diesel 1000 is factor to convert milli-litre into litres
