  • Performance and emission characteristics of methyl ester from non-edible
           oils in a DI diesel engine with additive and advance injection

      Authors: S. Vijayaraj; J. Sarangan
      Pages: 89 - 108
      Abstract: The main objective of this investigation was to study the use of neat methyl esters in DI diesel engine experimentally. Preparation of methyl esters were from non-edible oils of Jatropha curcus, Pongamia pinnata and neem (Azadirachta indica) using transestrification process. The results of the use of neat methyl esters without any modification in the engine parameters and fuel shows reduced performance with increased emissions of NOx compared with diesel. In order to improve the performance with reduced NOx emission, the fuel injection was advanced by 3 CA and a 3% by volume of diethyl ether is added as additive with the fuel. After the above engine and fuel modification, the results shows an appreciable increase in performance and reduced HC, NOx and CO emissions with a slight increase in smoke compared with neat methyl esters without any modifications. Also better performance comparable with diesel with reduced emissions is observed.

  • Comparison of blends of conventional diesel fuel and CRBO containing high

      Pages: 109 - 124
      Abstract: This work attempts to analyse the ability of high free fatty acid (FFA) crude rice bran oil (CRBO) in replacing diesel partially in a compression ignition (CI) engine. It was observed that the delay period and the maximum rate of pressure rise for CRBO blends are lower than diesel and is almost inversely proportional to FFA content. Maximum heat release rate for CRBO blends are lower and occur earlier than that of diesel. CRBO blends require longer duration to release 90% of heat than diesel and it decreases with increase in FFA content of CRBO. When operating with CRBO blends, all emission parameters were decreased significantly with a marginal increase in CO emission than that of diesel without affecting the brake thermal efficiency of the engine. It is concluded that higher FFA of CRBO blends does not inhibit its ability to be utilised as a fuel in CI engines.
      Keywords: crude rice bran oil; CRBO; free fatty acids; FFA; fuel blends; combustion; vegetable oil; diesel; compression ignition engines; brake thermal efficiency; alternative fuels; biodiesel.

  • Performance and emissions of a dual fuel operated diesel engine

    • Free pre-print version: Loading...

      Authors: N. Kapilan; R.P. Reddy
      Pages: 125 - 134
      Abstract: Vegetable oil and its esters (biodiesel) are the renewable alternative fuels that can be used as a substitute for diesel in the diesel engines. The vegetable oil fuelled diesel engine results in lower efficiency and higher smoke emission. Hence in this work, an attempt has been made to use inedible and under utilised mahua oil (MO) as a substitute for diesel by fumigating liquefied petroleum gas (LPG) along with the air. A single cylinder diesel engine was modified to work in dual fuel mode by suitable retrofitting. The MO was injected into the cylinder using a fuel pump and LPG was fumigated along with the air. In MO + LPG dual fuel mode, 9% increase in brake thermal efficiency and 35% reduction in smoke emission of the engine were observed as compared to the sole fuel mode with MO. Also, the engine performance characteristics in MO + LPG dual fuel mode are close to sole fuel mode with diesel. From this work, it is concluded that LPG can be fumigated along with the air to increase the performance of MO fuelled agricultural diesel engine.
      Keywords: alternative fuels; mahua oil; liquefied petroleum gas; LPG; dual fuel mode; engine performance; emissions; biodiesel; vegetable oil; diesel engines; brake thermal efficiency; agricultural engines.

           characteristics of DI diesel engine running on Calophyllum inophyllum linn
           oil (honne oil)

      Authors: B.K. Venkanna; C. Venkataramana Reddy
      Pages: 135 - 147
      Abstract: The present work examines the use of a non-edible vegetable oil namely honne oil, a new possible alternative fuel for diesel engine. A direct injection (DI) diesel engine typically used in agricultural sector was operated on neat diesel (ND) and neat honne oil (H100). Static injection timing (start of static injection timing) was changed to study the performance, emission and combustion characteristics. It was observed that advancing the injection timing with H100 from the rated static injection timing (23° bTDC) increased the brake thermal efficiency and reduced CO, HC emissions and smoke opacity; however, NO<SUB align="right">x emission was increased. The ignition delay with H100 was higher than that with ND for all static injection timing under consideration. Improved premixed heat release rate was observed with H100 when the static injection timing is advanced however, for 28° bTDC premixed heat release rates decreased. The best static injection timing was found to be 27° bTDC for H100 based on brake thermal efficiency.

      Abstract: In Asia, three-wheelers (auto rickshaws) represent a very important mode of intermediate public transport and serving as an effective feeder to the mass transport system. However, the significant contribution to pollution levels by three wheelers has demanded for a possibility of a future solution to ensure better air standards in urban areas where the population of auto rickshaws are higher. Interest is growing in plug-in hybrid technology that offers advantages of clean and more efficient vehicles compared to the current hybrids. In this paper, the development of a novel energy management strategy suitable for Indian city driving conditions for a converted plug-in hybrid auto rickshaw is discussed. The automatic switching strategy incorporated in the control system of the plug-in hybrid auto rickshaw enables the vehicle to offer better fuel economy and advantages of lower emission, by minimising the idling and slow power running regions of an internal combustion engine. The vehicle's energy management strategy has been tested with the various modes for the plug-in hybrid auto rickshaw. The implementation of plug-in hybrid concept with a novel drive strategy for three-wheelers will lead to reduction of urban emissions and hence better air quality for Indian cities and also provides much cheaper public transportation system.

  • Performance of a direct diesel engine using aviation fuels blended with

      Pages: 165 - 180
      Abstract: In this study, jet fuel (JF) and railroad fuel (D2) with SME blends (5%, 20%, 50%) were used in a four-cylinder, naturally aspirated, direct (DI) diesel engine. The engine was operated under full load and tested at various speeds to determine the engine's performance and exhaust emission characteristics. The experimental results show that as the SME ratio of the fuels increases, the break specific fuel consumption (BSFC) and exhaust temperature increase; the SME and its blends show a slight drop in engine performance. In this experiment, carbon monoxide (CO), carbon dioxide (CO<SUB align="right">2), nitrogen oxides (NO<SUB align="right">x) and smoke opacity values were measured for each fuel. The results of the emission tests revealed that the oxygen content of SME provided a significant reduction in CO and smoke opacity emissions. However, when the test engine was fuelled by SME and its blends, NO<SUB align="right">x emissions increased.
      Keywords: alternative fuels; soybean oil methyl ester; diesel engines; jet fuel; aviation fuels; biodiesel; engine performance; exhaust emissions.

      Abstract: This article represents the results of a single cylinder engine using specially designed electronically actuated fuel injection system fuelled with neat CNG, and mixtures of hydrogen in natural gas (HCNG) of 5, 10, 15 and 20% by energy. Experiments were conducted with wide open throttle and varying the equivalence ratio. Hydrogen which has fast burning rate, when added to compressed natural gas enhances its flame propagation rate. This was reflected in drastic improvement in emission characteristics and increase in lean burn limit. The emissions of HC, CO, decreased with increasing percentage of hydrogen but NOx was found to increase. With the increase in hydrogen supplementation, brake thermal efficiency increased and maximum brake torque timing decreased at similar equivalence ratio. The combustion analysis conducted showed that hydrogen supplementation shifted the peak pressure towards TDC and increased the heat release rate.
      Keywords: emissions; IC engines; compressed natural gas; CNG; hydrogen supplementation; engine performance; combustion; fuel injection; flame propagation; brake thermal efficiency; brake torque timing; heat release rate; alternative fuels.
