Fuel Consumption Tabulation in Laboratory Conditions

This paper examines the fuel economy displayed
by passenger vehicles and attempts to connect vehicular fuel consumption to such easily measurable parameters as vehicle speed, acceleration, gear and throttle position. The central contention is to understand how fuel consumption is connected to driving parameters in order to utilise such findings to reduce vehicle fuel consumption in future vehicle design. The New European Drive Cycle (NEDC) has been utilised as the testing framework to derive the mathematical relationship between fuel consumption and measurable driving parameters. The NEDC was simulated under laboratory conditions, and driving parameters together with
the fuel consumption were measured. A few driving phases were identified so that any drive cycle may be composed by these phases; and mathematical relationships have been fitted on measured data for each of the phases.
