“…Many papers indicate biodiesel as a valid replacement of diesel oil for Compression Ignition (CI) engines [1][2][3][4]. In comparison to fossil diesel oil, biodiesel presents several advantages: first of all, it is a renewable energy source; second, the environmental impact in terms of CO2 is strongly attenuated by the amount of carbon dioxide absorbed by the plants during the growing process [5]; third, some emissions, such as soot, are generally lower than in fossil fuel, as reported in [6,7].…”

Rape-seed biodiesel is an interesting option to address the problem of decreasing availability of conventional fossil fuels, as well as to reduce the CO2 emissions of internal combustion engines. The present paper describes an experimental campaign carried out on a current production 4-cylinder, 4-stroke naturally aspirated diesel engine, running on standard diesel fuel and on three different blends of rape-seed biodiesel (20%-50%-100%). Performance, emissions and in-cylinder pressure traces were measured at full load. It was found that the influence of rape-seed biodiesel in the fuel blend is not constant at each operating condition. However, as the biodiesel content increases, full load performance tends to drop, in particular brake specific fuel consumption (maximum worsening: +18%), while soot emission goes down. The maximum improvement observed in terms of soot concentration is 37.5%, at 1200 rpm. The combustion analysis revealed that the main differences among the fuels occur in the first phase of combustion: the burn rate is slower for biodiesel blends at low speeds, and faster at high.

SUMMARY Honne oil methyl ester (HOME) is produced from a nonedible vegetable oil, namely, honne oil, available abundantly in India. It has remained as an untapped new possible source of alternative fuel that can be used for diesel engines. The present research is aimed at investigating experimentally the performance, exhaust emission, and combustion characteristics of a direct injection diesel engine (single cylinder, water cooled) typically used in agricultural sector over the entire load range when fuelled with HOME and diesel fuel blends, HM20 (20% HOME + 80% diesel fuel)–HM100. The properties of these blends are found to be comparable with diesel fuel conforming to the American and European standards. The combustion parameters of HM20 are found to be slightly better than neat diesel (ND). For other blend ratios, these combustion parameters deviated compared with ND. The performance (brake thermal efficiency (BTE), brake‐specific fuel consumption, and exhaust gas temperature) of HM20 is better than ND. For other blend ratios, BTE is inferior compared with ND. The emissions (CO and SO) of HM20–HM100, throughout the entire load range, are dropped significantly compared with ND. Unburned hydrocarbon emissions of HM20–HM40, throughout the entire load range, is slightly decreased, whereas for other blend ratios, it is increased compared with ND. NOx emissions of HM20, throughout the entire load range, is slightly increased, whereas for other blend ratios, it is slightly decreased. The reductions in exhaust emissions together with increase in BTE made the blend HM20 a suitable alternative fuel for diesel fuel and thus could help in controlling air pollution.

“…Ozsezen et al (2009) found that combustion characteristics slightly changed (increased peak cylinder pressure and reduced ignition delay period (IDP)) compared to neat diesel (ND). Engine performance (brake-specific fuel consumption (BSFC) and brake thermal efficiency (BTE)) with biodiesel slightly goes down (Raheman andGhadge 2007, Sahoo et al 2007) or slightly goes up , Murugesan et al 2009, Puhan et al 2009 or may (no change) change little (Ozsezen et al 2009) compared with the ND. The inferior performance with biodiesel was due to its fuel properties and in turn combustion characteristics.…”

This study is aimed to investigate experimentally the combustion, exhaust emissions and performance characteristics of a direct injection (DI) diesel engine, typically used in the agricultural sector, when fuelled with neat diesel (ND), and abundantly available but untapped honne oil methyl ester (HOME) is used in diesel engines. The static injection timing (SIT) is varied from 23 crank angle (CA) (manufacturer's specified value) to 28 CA. The combustion parameters of HOME improved as SIT increased. The brake thermal efficiency (BTE) of HOME (SIT 27-28 CA before top dead centre (bTDC)) is the highest; however, still it is less than ND. The emissions (smoke opacity (SO), CO, HC and NO x ) of HOME (SIT 23-28 CA bTDC), through out the entire load range, are dropped compared to ND. The reductions in exhaust emissions (SIT 27-28 CA bTDC) together with increase in BTE made the HOME (SIT 27-28 CA bTDC) a suitable alternative fuel for diesel fuel and thus could help in controlling air pollution.
