Engine Performance And Emissions

In this study the influences of ethanol addition to gasoline on an spark ignition engine performance and emissions were explored. AVL BOOST software was used to simulate the performance and emission characteristics of different ethanol-gasoline blends. The blended fuels contain 5%, 10% and 15% of ethanol by volume, and indicated as B95E5, B90E10, and B85E15, respectively. The results showed that ethanol addition to gasoline fuel improve combustion process, decrease CO emissions and reduce BSFC of the SI engine.

Engine Performance And Emissions

Engine performance and emission characteristics were investigated using a single cylinder four-stroke diesel engine with different concentrated intermetallic-based Al–Fe–Mg–Si pistons. Three different alloy combinations (types A, B, and C) of Al–Fe–Mg–Si pistons were developed through the incremental alloying addition of Fe, Mg, Mn, Cu, and Ni. Piston types A, B, and C had Fe-rich intermetallic compounds (IMC), where types B and C had a higher density IMC distribution than type A. The influence of Fe, Mg, Mn, Cu, and Ni alloyed IMC pistons on engine performance and emissions was investigated at various loading conditions. Combustion characteristics such as cylinder pressure and net heat release rate for all piston types were investigated and compared. A similar duration of ignition was seen for all piston types. Frictional loss was reduced by ∼25% in types B and C in comparison to type A. Similarly, mechanical and thermal efficiency were enhanced considerably in types B and C compared to type A. Emission characteristics were also investigated for all piston types. Results showed that NOx was reduced by ∼17.3% with the use of types B and C.

Engine Performance And Emissions

Lean-burn combustion dominates the current reciprocating engine R&D efforts due to its inherent benefits of high BTE and low emissions. The ever-increasing push for high power densities necessitates high boost pressures. Therefore, the reliability and durability of ignition systems face greater challenges. In this study, four ignition systems, namely, stock Capacitive discharge ignition (CDI), Laser ignition, Flame jet ignition (FJI), and Nano-pulse delivery (NPD) ignition were tested using a single cylinder natural gas engine. Engine performance and emissions characteristics are presented highlighting the benefits and limitations of respective ignition systems. Optical tools enabled delving into the ignition delay period and assisted with some characterization of the spark and its impact on subsequent processes. It is evident that advanced ignition systems such as Lasers, Flame-jets and Nano-pulse delivery enable extension of the lean ignition limits of fuel/air mixtures compared to base CDI system.

Abstract Experiments are performed on a diesel engine working in single fuel mode using fossil diesel (FD) as well as 5% and 10% (v/v) di-ethyl ether (DEE) additives with FD as fuels as well as in dual fuel mode using the above fuels as pilot fuels along with producer gas (PG) as primary fuel. This study aims to draw comparative analyses of engine combustion, performance and emission characteristics using the above fuel combinations to establish the most suitable fuel strategy for a diesel engine. The study revealed greater control over nitric oxide (NO) and smoke opacity in dual fuel mode compared to single fuel mode operations. Addition of DEE with FD, produced lower HC and CO emissions, comparable NO emissions along with reduced smoke opacity compared to FD in both modes of operation. Further, in dual fuel mode operation, the diesel percentage energy substitution (PES) reduced with increase in DEE content in the blends. The tradeoff study involving engine performance and emissions with respect to the cost of operation revealed that the fuel strategy used in dual fuel mode operation delivered better engine performance along with reduced NO emission and smoke opacity at lower operational cost compared to all the considered fuel strategy in single fuel mode operation. Especially, FD+5% DEE+PG and FD+10% DEE+PG fuel strategies were found to be the most suitable dual fuel mode combinations in a diesel engine in terms of their superior engine performance, lower emissions along with better economy.
