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

Assessment of Noise Levels of Churches in the Kpone Katamanso Municipal Assembly in Ghana

The Scientific World Journal, Volume 2024, Issue 1, 2024.
Different sound levels are encountered by pastors, ministers, and the whole congregation during church services, which may extend for hours, and also by people living close to these churches. This can have an adverse effect on their health. The maximum allowable noise level in worship places is 65 dB (A), according to the Ghana Standards Authority (GSA)
