Effect of Variable Compression Ratio on Performance of a Diesel Engine Fueled with Karanja Biodiesel and its Blends

Abstract

Rapid exploration and lavish consumption of underground petroleum resources have led to the scarcity of underground fossil fuels moreover the toxic emissions from such fuels are pernicious which have increased the health hazards around the world. So the aim was to find an alternative fuel which would meet the requirements of petroleum or fossil fuels. Biodiesel is a clean, renewable and bio-degradable fuel having several advantages, one of the most important of which is being its eco-friendly and better knocking characteristics than diesel fuel. In this work the performance of Karanja oil was analyzed on a four stroke, single cylinder, water cooled, variable compression ratio diesel engine. The fuel used was 5% -25% karanja oil methyl ester by volume in diesel. The results such obtained are compared with standard diesel fuel. Several properties i.e. Brake Thermal Efficiency, Brake Specific Fuel Consumptions, Exhaust Gas Temperature are determined at all operating conditions & at variable compression ratio 17 and 17.5.

Improvement of performance and emission characteristic of waste plastic pyrolytic oil blended diesel fuel in variable compression diesel engine using graphene nano additive

“…25 Mishra tested the Karanja oil diesel blend in a variable compression diesel engine and found an increase in engine performance at a compression ratio of 17.5 and a blend of 25% at all loading circumstances. 26 Attri et al found that CR of 17 exhibited improvement in thermal efficiency and control in BSFC by using 1-butanol blended diesel in a four-stroke CI engine. While an increment in the compression ratio up to 18 resulted in reduction of HC, CO, and NOx emissions.…”

Kinematic and Dynamic Response of a Novel Engine Mechanism Design Driven by an Oscillation Arm

“…However, most benefits are related to minimal fuel consumption, minimal nitric oxides and particulate matter emissions [11]. To obtain superior performances, a cumulative method is required for improving the design process and final geometry, combustion process parameters [12][13][14][15] type of fuel [16] and other environmental parameters.…”
