Ammonia Combustion in a Spark-Ignition Engine Supported with Dimethyl Ether

Energies, 2023
This paper presents the results of experimental tests with a spark-ignition engine powered using ammonia and DME (dimethyl ether). The tests were carried out on a CFR (cooperative fuel research) engine with a compression ratio of 10 and a rotational ...

The Prediction of Spark-Ignition Engine Performance and Emissions Based on the SVR Algorithm [PDF]

Processes, 2022
Engine development needs to reduce costs and time. As the current main development methods, 1D simulation has the limitations of low accuracy, and 3D simulation is a long, time-consuming task. Therefore, this study aims to verify the applicability of the

Chaotic Combustion in Spark Ignition Engines [PDF]

, 2002
We analyse the combustion process in a spark ignition engine using the experimental data of an internal pressure during the combustion process and show that the system can be driven to chaotic behaviour.

Coupling a Lagrangian–Eulerian Spark-Ignition (LESI) model with LES combustion models for engine simulations

Science and Technology for Energy Transition, 2022
In the United States transportation sector, Light-Duty Vehicles (LDVs) are the largest energy consumers and CO2 emitters. Electrification of LDVs is posed as a potential solution, but SI engines can still contribute to decarbonization.
