Investigating the Impact of Ignition Timing Variations on Single-Cylinder Otto Engine Performance with E50 Fuel Blend
Journal Title: Journal of Sustainability for Energy - Year 2023, Vol 2, Issue 3
Abstract
The exponential growth in motorized vehicle usage presents myriad challenges, encompassing environmental pollution and sustained energy shortages. To address these challenges, the exploration of sustainable energy alternatives is imperative, with ethanol-based fuels emerging as a viable option. This investigation delves into the performance of a single-cylinder Otto engine, with a focus on the effects of ignition timing variations using a 50% ethanol and 50% pertalite blend, denoted as E50. The ignition timing was systematically varied to standard, +2°, +4°, and -2°. The results demonstrated that the +4° ignition timing, in conjunction with E50, delivered superior performance, culminating in a maximum torque of 8.02 Nm at 4000 rpm and a peak power output of 4.15 kW at 8000 rpm. Concurrently, optimal engine efficiency was achieved, with the Brake Specific Fuel Consumption (BSFC) reaching its lowest value of 0.307 Kg/kW.h at 5000 rpm and Brake Thermal Efficiency (BTE) peaking at 36.10% at the same rotational speed. When contrasted with alternative fuels, the E50 blend resulted in an average torque reduction of 13.27% and a 14.46% decrease in power output. Despite this, significant enhancements in engine efficiency were observed. A 25.05% improvement in BSFC was noted, albeit with a reduction in fuel efficiency, while BTE experienced a 5.02% increase, indicative of augmented engine efficiency, particularly at the +4° ignition timing. This study underscores the potential of E50 and altered ignition timing in reducing reliance on fossil fuels, thus contributing to the transition towards sustainable energy solutions in the automotive sector.
