Abstract:
This paper investigates the effect of ethanol-unleaded gasoline blends (E۰,E۱۰,E۲۵,E۳۵,andE۶۵) computer interfaced, four-stroke single cylinder compression ignition engine. The said engine wasconverted to spark ignition and carburetion to suit ethanol fuel. A suitable provision was provided on theengine to vary the compression ratio thereby making the engine adaptable to operate at lowercompression ratios. The tests were performed by varying the ignition timing, equivalence ratio, andcompression ratio at a constant speed of ۱۵۰۰ rpm and at wide open throttle (WOT). Effect of ethanolunleadedgasoline blends and tests variables on engine torque and specific fuel consumption wereexamined experimentally. The results of this investigation, is believed, to contribute substantially to theknowledge, aimed to ensure a secure future energy.
