The utilization of gaseous fuels in internal combustion (IC) engines is receiving more significant greater interest in recent years because of their better fuel mixing characteristics. Apart from potential gaseous fuels such as liquefied natural gas (LPG), compressed natural gas (CNG), and hydrogen, other alternatives are being explored for their utilization in IC engines. The reason for this exploration is mainly because of the durability and robust nature of compression ignition (CI) engines, and more research focuses on the utilization of a variety of gaseous fuels in CI engines. However, gaseous fuels need to be used in CI engines on dual fuel mode only. In this investigation, a single-cylinder, four-stroke, air-cooled diesel engine was converted into Acetylene run dual-fuel CI engine by changing the intake manifold of the test engine. Acetylene at three flow rates viz., 2lpm, 4lpm, and 6lpm were introduced into the intake port by manifold induction technique while Jatropha biodiesel/diesel was injected directly into the cylinder. In this paper, the effect of manifold induction of Acetylene on the performance and emission characteristics…

Analysis of Whole Body Vibration of a Two-Wheeler Rider

NIT Rourkela-Kashish Veda Eluri, Vadde Lokesh Reddy, Murugan Sivalingam, Balaji PS
Published 2019-04-02 by SAE International in United States
Two-wheel motorcycles are preferred in many countries as they have some merits such as cheaper, easy to handle and give higher fuel economy compared to three and four-wheel vehicles. Majority of the population in India falls under low and middle-income groups. Two-wheelers cater to the needs of low and middle-income users, and fill the gaps when public transport systems are inefficient or not available. Most of the people in India use motorcycles for transportation. However, due to different road conditions, motorcycle rider experiences different health effects within a few years of their vehicle travel. This paper investigates the effect of vibration on a man commuter’s health. For this purpose, a mathematical model of a male rider’s body was considered, and a numerical analysis was carried out to assess the effect of vibration acting on the commuter during a two-wheeler ride under various road conditions for a chosen suspension system and presented in this paper. Road conditions were chosen based on the different surface roughness values. The most affected rider’s body part due to the vibration…

Performance and Emission Characteristics of a Diesel Engine Fueled with Diesel and Orange Oil Blends Using Different Bowl-In Piston Geometries

Biomass derived fuels have a potential to replace fossil fuels that are used in transportation. Orange oil is considered as one of the possible alternative biofuels for compression ignition (CI) engines, as it is renewable and available in a significant quantity throughout the world. It is a biomass derived fuel obtained from orange skin, which has 90% D-limonene. In this study an orange oil diesel blend is used as a test fuel in a single cylinder, four stroke, direct injection (DI) diesel engine with a power output of 4.4 kW at a rated speed of 1500 rpm to assess the performance and emission parameters of the engine, when the engine is run with three different piston geometries. The experimental results of the performance and emission parameters of the engine for the orange oil operation were compared with those of the diesel operation of the same engine and presented in this paper.

Investigation on Performance and Exhaust Emissions Characteristics of a DI Diesel Engine Fueled with Karanja Methyl Ester and Biogas in Dual Fuel Mode

NIT Rourkela-Debabrata Barik, Murugan Sivalingam
Published 2014-04-01 by SAE International in United States
The present study was aimed to run the diesel engine only with two renewable fuels in a dual fuel mode. The karanja methyl ester (KME) derived from karanja oil was used as an injected fuel, and the biogas obtained from the anaerobic digestion of pongamia pinnata (Karanja) de-oiled cakes, was used as a secondary fuel in a single cylinder, four stroke, air cooled, direct injection (DI) diesel engine. Four different flow rates of biogas, viz., 0.3 kg/h, 0.6 kg/h, 0.9 kg/h and 1.2 kg/h were inducted along with the air in the suction of the engine. The results of the experiment were compared with those of diesel and KME operations. Biogas inducted at a flow rate of 0.9 kg/h was found to be the best among all the flow rates, in terms of the performance and emission of the engine. The dual fuel operation showed a higher BSEC than that of diesel operation at full load. In dual fuel operation, about 22% of KME replacement was possible with the biogas flow rate of 0.9 kg/h…

Effect of Diethyl Ether (DEE) Fumigation on Engine Performance and Emissions in a Bioethanol Fueled Diesel Engine

NIT Rourkela-Navin Kumar, Abyarth Behera, Dulari Hansdah, Murugan Sivalingam
Published 2014-04-01 by SAE International in United States
Madhuca indica flower is a forest residue used for preparation of food and liquor in tribal areas of India. In this present investigation, bioethanol produced from madhuca indica flower by the fermentation process is proposed as an alternative fuel for diesel engines. As the cetane number of bioethanol is low, an ignition improver is required for better operation. In this study, Diethyl ether (DEE), an ignition improver is fumigated at two different flow rates viz 120 g/h and 240 g/h in the intake manifold along with the air in a single cylinder, four stroke, DI diesel engine developing a power of 4.4 kW at a rated speed of 1500 rpm. The brake thermal efficiency (BTE) is found to be higher by about 10.47 and 2.46% with 120 g/h and 240 g/h flow rate of the DEE respectively, compared to that of diesel at full load. The brake specific nitric oxide (BSNO) emission is found to be lower for both the flow rates, but the brake specific carbon monoxide (BSCO) and brake specific hydrocarbon (BSHC) emission…
