Study on the Combustion and Emission Characteristic of a Heavy‐Duty Natural Gas/Ammonia RCCI Engine with Diesel Ignition

International Journal of Energy Research, Volume 2024, Issue 1, 2024.
As a carrier of hydrogen, ammonia has great potential in reducing pollution and carbon. This paper investigates the impact of diesel compression ignition on the combustion and emission performance of a natural gas/ammonia mixture RCCI engine through numerical simulation. The energy fraction of ammonia is set from 0% to 100% in the study to evaluate the

Response Analysis of an Experimental Study on the Effect of Speed and Premixed Fuel Ratio on Performance and Emissions in RCCI Engine

International Journal of Chemical Engineering, Volume 2024, Issue 1, 2024.
Even though CI engines are more efficient than SI engines due to their ability to operate at a greater compression ratio, a leaner charge, and lower throttle losses, they have higher PM and nitrogen oxide emissions. The induction system modification with fuel port injection is used as a parameter in RCCI engine operations for controlling emission ...
