Study of the Performance and Smoke Density When Gasoline–Diesel Blends Are Used as Fuel of a Diesel Engine

Journal of Engineering, Volume 2025, Issue 1, 2025.
The world is currently facing a serious environmental crisis, partly driven by the pollutant emissions from diesel engines. Although these engines are known for their efficiency, their emission levels are highly dependent on fuel quality. In Colombia, despite having one of the highest‐quality fuels in the region, its properties still fall short of ...

A Two‐Zone Multigrid Model for SI Engine Combustion Simulation Using Detailed Chemistry

Journal of Combustion, Volume 2010, Issue 1, 2010., 2010
An efficient multigrid (MG) model was implemented for spark‐ignited (SI) engine combustion modeling using detailed chemistry. The model is designed to be coupled with a level‐set‐G‐equation model for flame propagation (GAMUT combustion model) for highly efficient engine simulation.

Investigation on PCCI combustion with cetane improver as secondary fuel for hybrid engine application

Results in Engineering
Premixed charge compression ignition (PCCI) reduces in-cylinder temperatures by transitioning combustion to a more premixed phase. As a consequence, nitrogen oxide (NOx) and smoke emissions reduced.

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

International 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

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 ...
