Abstract: Reduction of cold-start emissions using electrically-heated catalyst (EHC) technology was the focus of this work. Comprehensive emission measurements of CO, CO2,NOx, and total hydrocarbons (THC) ...

Abstract: An analytical model of a two-stroke cycle, reciprocating, compression ignition engine was used to investigate the ignition and combustion characteristics of coal/water slurry fuels. The engine ...

Abstract: Utilization of alternative fuels in the transportation sector has been identified as a potential method for mitigation of petroleum-based energy dependence and pollutant emissions from mobile ...

Abstract: Natural gas has been used extensively as an engine fuel in gas pipeline transmission applications and, more recently, as a fuel for transportation applications including both light-duty and ...

Abstract: A Caterpillar 3406 turbocharged diesel engine was converted to operate in a natural gas with diesel pilot ignition mode and was evaluated for performance and emission characteristics for both ...

Abstract: Typical conventional diesel engine designs are based on arrangements of single piston and cylinder sets placed sequentially either in-line or offset (“V”) along the crankshaft. The development ...

Abstract: Measurements are reported for a spark-ignited (SI) engine burning natural gas and three simulated biogas fuels (natural gas, CO2, and N2 mixtures). Exhaust concentrations of CO, CO2,O2,NOx, and ...

Abstract: The performance and emissions of a single-cylinder natural gas fueled engine using a pilot ignition strategy have been investigated. Small diesel pilots (2–3% on an energy basis), when used to ...

Abstract: The Advanced (injection) Low Pilot Ignited Natural Gas (ALPING) engine is proposed as an alternative to diesel and conventional dual fuel engines. Experimental results from full load operation ...
