Abstract

In this research paper, a Bajaj rickshaw vehicle was tested under variable loads and five different oil - fuel mixture ratios ranging between 2% and 12.5%. Three readings of each experiment were taken and average values were extracted. It was found that oil - fuel mixture ratios which lie between 2% and 5% are the most suitable ratios that could be used by rickshaw drivers and technician mechanics. These ratios are recommended to be used because they give the vehicle's engine higher acceleration, longer operation period life, diverge the overhaul maintenance period intervals, and that they cause less impact to the surrounding environment.
