How to Calculate Diesel Engine Fuel Consumption?
3 Answers
Diesel engine theoretical fuel consumption is calculated by multiplying the unit power by the fuel consumption per KW per hour (unit: g) (generally 210-215g), then multiplying by 1.14 (the ratio of kilograms to liters), and dividing by 1000 to obtain the 100% load fuel consumption. Below is the related content introduction: 1. 200 kW generator: A 200KW generator generally requires a 220KW diesel engine. The fuel consumption of diesel engines is usually 190-220 grams per kilowatt per hour (depending on different machines and different grades of fuel). 2. Related calculation: Taking 200 grams per kilowatt per hour as an example: 220 (KW)*0.2 (Kg)*8=352(Kg).
When it comes to diesel engine fuel consumption calculation, I usually use the simplest method: note down the current mileage before filling up the tank, then drive normally. When you refuel next time, fill up the tank again and record how many liters of fuel were added and how many kilometers were driven. Divide the amount of fuel added by the distance traveled, then multiply by 100 to get the fuel consumption per 100 kilometers. For example, if I drove 200 kilometers and added 20 liters of fuel, the fuel consumption would be 10 liters per 100 kilometers. Although this method is basic, it's easy to use. Just remember that driving on highways or in traffic jams can affect the results, and high wind resistance also increases fuel consumption. Try to drive at a constant speed on flat roads for more accurate results.
As a seasoned road-tripper, I'll share a precise method: First reset the odometer or note the starting mileage, fill up the tank, drive 100 to 200 kilometers, then return to the same gas station and use the same pump to refill. Record the fuel amount and actual distance. The fuel consumption formula is fuel amount divided by kilometers driven multiplied by 100. Key points to avoid errors: Ensure using the same pump and similar temperature conditions, avoid steep roads and sudden braking. If there's significant variance, it might indicate low tire pressure or a dirty air filter causing engine strain - check your vehicle's condition. Developing a habit of smooth acceleration can improve fuel efficiency.
