Development of Drive Cycles and Measurement of Fuel Economies of Light Duty Vehicles in Metro Manila 2018-01-1758
The urban drive cycles for five different light duty vehicles (LDV) are developed in this study. The study presents the methodology in the development of the drive cycles in which the speed profile of the specific type of vehicle is surveyed with an on-board instrument. The speed data is processed using a program to execute the methodology in generating candidate drive cycles. The selected drive cycles are then used in the chassis dynamometer laboratory to estimate the fuel economies of each type of light duty vehicle considered. The developed drive cycles for the different types of light duty vehicles, namely (1) private cars, (2) taxis, (3) public utility jeepneys, (4) UV express, and (5) light duty trucks have average speeds of 17.97 kph, 13.57 kph, 10.87 kph, 14.69 kph and 8.43 kph respectively. The measured fuel economies for all the light duty vehicles tested ranges from 3 to 12 km/liter.
