Chapter 7 - Literature review Example Utilizing theoretical and experimental methods, a uniform mathematical model was arrived at that could be applied to small parts of the overall drive cycle to predict fuel consumption without any need for physical testing. The primary objectives of this study were to determine engine speed and engine torque. In addition to the primary objectives, a number of different input and output parameters need to be determined to ensure that the engine is operating within safe limits and optimally. Secondary parameters that required determination and control during testing included (but were not limited to): Measurement of the parameters listed above was done using automated means in order to enhance accuracy (Gitano-Briggs, 2008, p.40). Moreover, this allowed real time monitoring of equipment to perform adjustments online. The primary aim of this research was to examine the fuel consumption of passenger vehicles based on a standardized driving cycle. In addition, this research aimed to explore the development of a mathematical model that could be used to predict the fuel consumption of passenger vehicles. The current research was able to meet its objectives in large part. Laboratory and real life driving provided significant findings on fuel consumption of passenger vehicles. A mathematical model was developed based on the NEDC driving cycle that was validated for most testing regimes in the driving cycle. However, the current mathematical model has certain limitations in the NEDC driving cycle and is also limited for other standard driving cycles. The current research provides a mathematical model for validating fuel consumption over the NEDC driving cycle under urban and extra urban driving conditions. Additionally, laboratory testing of engines was carried out in order to determine operating parameters. Laboratory testing was done through a generator type dynamometer based on engine torque testing. The mathematical
