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.

Computational Analysis of Spray Angle Effects on Combustion and Emissions in Methane‐Diesel Dual‐Fuel Engine

Energy Science &Engineering, Volume 14, Issue 3, Page 1100-1112, March 2026.
This study concluded that wider spray angles produce wall impingement and greater unburned hydrocarbons in methane‐diesel dual‐fuel engines, whereas 110° balances efficiency and emissions. ABSTRACT A diesel methane dual fuel engine appears as a potential means for lowering emissions while retaining useful thermal efficiency.
