While many engines include fuel flow readouts, it’s also crucial to be able to estimate fuel use while purchasing for a boat or engine. Because the time it takes to cover a distance fluctuates more than it does on the road, fuel consumption is calculated in gallons per hour. How much fuel does a diesel engine burn per hour? Work done in a single cycle = Mean Indicated Pressure x Piston Area x Stroke Length =xx To calculate the power of this unit, multiply the work rate by the number of power strokes performed in one second. With a fuel consumption figure, you can now determine your vehicle’s touring range by dividing the vehicle’s fuel tank capacity by the fuel consumption and multiplying by 100 once more. Simply record the distance traveled since the last fill-up and the amount of fuel spent to cover that distance, then divide the litres consumed by the kilometres traveled and multiply by 100 to determine consumption in litres per 100 kilometers.įor example, if your vehicle used 60 litres of fuel to travel 450 kilometers, divide 60 by 450 and multiply by 100 for a rounded fuel consumption number of 13.3 litres per 100 kilometers. It is not difficult to calculate a vehicle’s fuel usage. How do you calculate the fuel consumption of a diesel engine per km? However, the calorific value of the fuel utilized for the sea trial may differ, necessitating the determination of a compensating factor to ensure accuracy in calculation. If not, the horsepower can be computed using engine rpm and average pump fuel index with the help of the manufacturer’s engine characteristic curve from numerous sea trials. If a dynamometer is installed on the engine shaft, the horsepower can be measured using a digital indication that displays the BHP.Following the above-mentioned bunker calculation process, the mass of the observed volume of fuel consumed can be computed.If the oil is just being delivered to the main engine, it can also be measured by jotting down the HFO service tank reading. The volume of fuel utilized is calculated using the difference in readings. The flow meter readings to the main engine should be recorded for a set time interval, such as one hour.The following is the formula for calculating SFOC: The SFOC is commonly used to measure the efficiency of marine engines.įuel consumption and power developed are always measured over a reasonable time period in favorable weather in order to attain precision. The mass of fuel required per unit time to create one KW is known as specific fuel oil consumption. How is marine engine fuel consumption calculated? QS = ge Pe / 36 f V, (1) where ge denotes the specific fuel consumption of a free-piston engine in estimated movement mode, g(kW*h)-1, and Pe is the power absorbed from the crankshaft of the engine. The following formula is used to hypothetically evaluate automotive fuel consumption QS at normal movement (in l(100 km)-1). * How is diesel engine fuel consumption calculated? “…put in its horsepower rating and multiply it by the specific fuel consumption average, then divide the product by the fuel specific weight,” says the author. However, while calculating your fuel use isn’t always perfect, it’s a wonderful place to start! On the sea, miles are difficult to measure, hence Gallons Per Hour (GPH) is utilized instead of the conventional MPH. A gasoline meter put on your boat is the only true way to measure fuel use. It’s crucial to remember that depending on how fast you’re driving and other factors, your fuel consumption may reduce or increase.
