The Effects of Camelina “Soheil” as a Novel Biodiesel Fuel on the Performance and Emission Characteristics of Diesel Engine

Abstract

Abstract:In this research, a new cultivar of Camelina "Soheil" seed oil (CSO) was investigated as a novel feedstock for biodiesel production. Maximum oil content of CSO seed was about 29%. Physical and chemical characteristics of CSO were investigated. The biodiesel production process was optimized by using the response surface methodology (RSM) reaction parameters, including molar ratio (methanol to oil), reaction time, and concentration of catalyst are studied. The result showed that the conversion of biodiesel was 98.91% under the optimized conditions of 10.18:1 molar ratio and 1.15 wt % concentration of catalyst for a reaction time of 7.33 min. By investigating the properties of the fuel, it turned out that biodiesel from new cultivar of CSO oil complied with the limits prescribed in the ASTM D6751 standards, and that this seed oil could be introduced as a new feedstock for biodiesel production. Also, the performance and emission of a diesel engine were investigated with CSO biodiesel. All of the engine experiments were performed under the constant speed of 2100 rpm at loads of 0%, 25%, 50%, 75%, and 100%. Results indicated that by using the biodiesel-diesel blends, the brake power, and the CO 2 and NOx emissions increased, while the SFC and CO and UHC emissions decreased.

An Investigation of Engine Performance and Exhaust Gas Emissions under Load Variations using Biodiesel Fuel from Waste Cooking Oil and B30 Blend

“…The characteristics biodiesel fuel are high density, viscosity, and content of oxygen so that it allows other impacts to arise which can affect engine performance, especially when using different loading variations. Researchers have recently set targets to improve the properties of biofuels in terms of exhaust emissions and engine efficiency 32,33,34,35,36,37) . Puniyani et al 32) examined a new source of biofuel from cottonseed oil, the findings from his research revealed that the utilization of biofuel derived from cottonseed oil led to a notable Brake Thermal Efficiency (BTE) reduction of 21.03%.…”

Optimization of an Ultrasonic-Assisted Biodiesel Production Process from One Genotype of Rapeseed (TERI (OE) R-983) as a Novel Feedstock Using Response Surface Methodology

“…Due to its low contamination during combustion, biodiesel has been utilized considerably in recent years [6,[11][12][13][14]. Various methods have been investigated in order to produce biodiesel [15].…”
