Effects of equivalence ratio and CNG addition on engine performance and emissions in a dual sequential ignition engine

International Journal of Engine Research, 2020
Compared to widening usage of CNG in commercial gasoline engines, insufficient but increasing number of studies have appeared in the open literature during last decades, while engine characteristics need to be quantified in exact numbers for each ...

Use of CNG and Hi-octane gasoline in SI engine: a comparative study of performance, emission, and lubrication oil deterioration

Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2019
The search for alternative fuels (i.e. other than gasoline) is a continuous area of research. In the present work, a comparative study has been conducted by employing a liquid ((G)97) and a gaseous (CNG) fuel in a spark ignition engine.

SS: CNG Transportation Technology in 2009, Marine CNG - Why hasn't it happened?

Offshore Technology Conference, 2009
Abstract Marine Compressed Natural Gas (CNG) is a technology that has evolved to a point where technical challenges no longer pose a hurdle to project development. The Class Societies have provided guidance and rules that allow for ship construction, and the proponents have completed the testing and certification ...

Experimental comparison of efficiency and emission levels of four-cylinder lean-burn passenger car-sized CNG engines with different ignition concepts

Combustion Engines, 2019
Today’s passenger car CNG engines are based on petrol engines which typically have restrictions preventing the exploitation of the full potential of methane based fuels, especially if they have to be operated also on petrol as a second fuel. Additionally,
