... Abstract Ammonia combustion in engines is a promising approach for decarbonization of the energy sector. If made from renewable energy sources, anhydrous “green” ammonia combustion results in zero net carbon dioxide emissions. As a renewable energy storage medium, green ammonia is superior...

... Abstract Crankcase ventilation systems are coming into new focus due to safety concerns associated with alternative fuels such as ammonia and hydrogen. In addition, innovation is being driven by increasingly stringent legislation that plays an important role in limiting crankcase emissions...

... Abstract A high-speed in-situ laser absorption sensor has been developed for cycle-resolved emissions analysis in the exhaust manifold of production-scale internal combustion engines. An inline sensor module, using optical fiber-coupling of interband and quantum cascade lasers, targets...

... Abstract Emissions management in hybrid-electric vehicles can be particularly critical. This is due to the drop of exhaust temperature during the shut-off phases of the thermal engine, which can lead the aftertreatment system to fall below its activation temperature. Traditionally, spark...

... and unregulated emissions coming out from the engine exhaust were compared. For economic assessment, annual fuel consumption and associated fuel cost were compared under similar engine operating conditions. The economic cost associated with the environmental impact was calculated based on carbon dioxide emissions...

... Abstract A fuel blend consisting of 10% S8 by mass (a Fischer-Tropsch synthetic kerosene), and 90% ULSD (Ultra Low Sulfur Diesel) was investigated for their combustion characteristics and impact on emissions during RCCI (Reactivity Controlled Compression Ignition) combustion in a single...

... Abstract This paper presents a study on the effect of injection rate on the performance and emissions of a direct-injection gasoline engine operated with seven kinds of DI injection and a port-injection. The injection pressures were set at 0.3 and 7 MPa for port injection and DI operation modes...

... design of the engine to achieve near zero particulate matter (PM) and NOx emissions for homogenous charge compression ignition (HCCI) engine. Therefore combustion simulations of the engine have been performed to find out flow development and emission generation in the cylinder. Moreover, the interaction...

...) mixtures at higher pressures and power levels with lower life cycle cost. Only then will these performance goals be attainable. Ignition systems for spark ignited, high BMEP, low emissions engines have historically been a problem from a performance and reliability standpoint. Low emissions, high BMEP...

... 19 11 2008 Derived from natural gas, coal, and even biomass Fischer-Tropsch (F-T) diesel fuels have a number of very desirable properties. The potential for emissions reduction with F-T diesel fuels in laboratory engine tests and on-road vehicle tests is well documented. While a number...

... 19 11 2008 Many of the stationary power generation and agricultural pumping applications in India utilize diesel engines. Recently, as per Government regulations, these engines are required to satisfy stringent emissions norms. This forms the motivation for the present study...
