1. hundred kilometers
hundred kilometers that when some cars on the road per 100 km average fuel consumption. It is a measure of automobile fuel consumption. For example: 10/100 = 60/600 left side of equation is theoretically 100 km, 10 oil consumption. The right hand side is a car traveling 600 kilometers, consuming 60 oil. Equation holds. The method
Actual fuel consumption calculated: X / 100 = 50/600 X is the number of liters hundred kilometers we ask the right equations are the vehicle traveling 600 km, the consumption of 50 liters. Founded equation, the solution of this equation, X = 50times; 100/600
The answer: Xasymp; 8.33
so the car about 8.33 liters hundred kilometers.
popular talk: after a few liters of fuel a second time multiplied by 100 and divided by the number of kilometers away from the first refueling the car running, the answer is to be a hundred kilometers fuel consumption.
is factory Theory hundred kilometers at a temperature, wind direction, wind speed and other environmental regulations objective, the vehicle remains at a certain speed flat road or on a chassis dynamometer (typically 60,90,120 km / h), then through the exhaust gas analyzer and carbon balance method (analysis of carbon content in the off-gas to determine how much fuel consumption), the final estimated data from the laboratory models hundred kilometers, since most vehicles close to 90 km / h economic speed, so most of the announced theoretical fuel consumption per hundred kilometers is usually 90 km / h constant fuel consumption.
