Performance Characteristic of Permanent Magnet Linear Generator for Energy Conversion with Renewable Fuels on Free‐Piston Engines

open access: yesInternational Journal of Energy Research, Volume 2024, Issue 1, 2024.
Renewable fuels attract more attention owing to reduction of both air pollution and greenhouse gas emissions compared to fossil fuels. The free‐piston engine generator is a new energy conversion with compact structure, multifuel combustion mode possibility, and less friction loss, and it can be applied to a variety of renewable fuels.

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

open access: yesInternational 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

open access: yesInternational 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 ...
