Emission and Performance Characteristics of VCR Engine with Pumpkin Seed Bio Diesel Blends

Abstract

The objective of the present study is to analyze the emission and performance characteristics at different compression ratio in VCR diesel engine using pumpkins seed. Bio diesel is prepared by trans-esterification process in biodiesel plant. Blends (20%, 40% and 60%)of pumpkin seed biodiesel and diesel blends are prepared and test were conducted at the load conditions (3-12 kg) The enforcement criterias like exhaust emissions, brake thermal efficiency( BTE) and Brake specific fuel consumption ( BSFC) been assessed and analyzed. And experimental results shows BSFC is same for diesel and biodiesel blends and at higher loads, 40% biodiesel blend has efficiency closer to the diesel, NOX emission in biodiesel blends have same at different loads, CO2 emissions gradually increases with increasing load.

Suitability Evaluation of Pumpkin Seed Oil Biodiesel as a Possible Diesel for Zambia

“…It has been established that biodiesel has low emission of greenhouse gases especially since the feedstock is biomass, so no overall carbon is introduced to the globe, blends of various biodiesels produce comparatively similar performance output as petroleum diesel, different seeds with oil including nonedible ones are alternatives otherwise completion with food the biodiesel might influence food prices globally. The cetane values scores of biodiesel have been relatively high in the range of 56 to 78 [1,2].…”

“…Besides petroleum diesel emits greenhouse gasses, and its unavailability is compared to the demand, hence leading to escalating commodity prices globally hence affecting all economies of the globe. These factors make it necessary to find an alternative fuel to diesel [1,2]. The alternatives to petroleum diesel have been biodiesel, ethanol, hydrogen, solar-powered cars, and electrically powered cars [3][4][5][6][7][8][9].…”
