Numerical study on the combustion process of a biogas spark-ignition engine por Carrera, José, Riesco, José, Martínez, Simón, Sánchez, Fausto, Gallegos, Armando

“…The combustion process of by biogas is characterized in terms tion of combustion, i. e., depending on the time elapsed while the reac- an of the dura tants (methane and oxygen) are transformed into products (mainly carbon dioxide and water). This study numerically evaluates the way in which the geometrical pa- rameters such as the compression ratio and operating parameters like engine speed, the excess air, the time of spark timing and carbon dioxide content of biogas affect the evolhution of the combustion process. …”
