Individual Project
Introduction
As what mr DAI already said, we need to made an Individual project and we need to choose a topic between 3 topics which are about Pyrolisis, Electric Vehicle, and Internal Combustion Engine
Chosen Topic :
I am choosing Internal Combustion Engine as a topic for my Individual Project with the title "Effect of octane on performance and energy consumption on BMW E36 330i
Synopsis
The combustion performance of gasoline engines has traditionally been measured using Research Octane Number (RON) and Motor Octane Number (MON) which describe antiknock performance under different conditions. Recent literature suggests that MON is less important than RON in internal combustion engine cars and a relaxation in the MON specification could improve vehicle performance, while also helping refiners in the production of gasoline. At the same time, for the same octane number change, increasing RON appears to provide more benefit to engine power and acceleration than reducing MON. It has also been suggested that there could be fuel efficiency benefits (on a tank to wheels basis) for specially adapted engines, for example, operating at higher compression ratio, on very high RON (100+). Other workers have advocated the use of an octane index (OI) which incorporates both RON and MON to give an indication of octane quality. The aim of this work is to investigate the effect of RON and MON on the power output and acceleration performance of gasoline-powered vehicles under full-throttle acceleration. The test was carried out in the context of the BMW E36 330i. RON oil cover Ratings of 91-98 and sensitivity at 15 (RON - MON) were mixed. Pure hydrocarbons and mixtures containing ethanol or ETBE can be included to determine the specific effect of the oxidizing agent. The results confirm from other studies that MON is not a good predictor of vehicle performance and that, in fact, high levels of MON under all acceleration conditions increase acceleration time.
