RISCooled Spray Technology for Particulate Reduction in a Heavy-Duty Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cooled spray (CS) technology passively reduces particulate matter (PM) emissions from diesel engines compared to non-CS-equipped diesel engines. CS inserts are mounted near the injector nozzle and control mixing so that ...
Influence of Diesel Fuel Injection Characteristics on Dual-Fuel Combustion Modes in a Large-Bore, Medium-Speed Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experiments were conducted on a large bore, medium speed, single cylinder, diesel engine to investigate operation with substitution ratio of natural gas (NG) varying from 0% to 93% by energy. In a previous study by the ...
Investigating the Combustion Performance of Dual Fuel Combustion With Diesel and Port Injected Hydrogen in A Large Bore Locomotive Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The heavy-duty transportation sector has primarily relied on conventional diesel combustion engines given their reliability and high thermal efficiency relative to spark ignition engines, but increased focus on reducing ...
Capturing Pressure Oscillations in Numerical Simulations of Internal Combustion Engines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In an earlier publication (Jupudi et al., 2016, “Application of High Performance Computing for Simulating Cycle-to-Cycle Variation in Dual-Fuel Combustion Engines,” SAE Paper No. 2016-01-0798), the authors compared numerical ...
