Introduction: Ignition timing, in a spark ignition engine, is the process of setting the time that an ignition will occur in the combustion chamber (during the compression stroke) relative to piston position and crankshaft angular velocity. Setting...

, the combustion process allows clean and controlled combustion, resulting in future improvement in fuel economy and emission control. In this study, the effects of mixtures of hydrogen and compressed natural gas (CNG) on a spark ignition engine are numerically...

natural gas (CNG) on a spark ignition engine are numerically considered. This article presents the results of a direct-injection engine using methane–hydrogen mixtures containing H2 between 0% and 15% by volume. The result shows that the percentage...

Preparation of air-fuel mixture is considerably dependent on the fluid flow dynamics in

order to achieve improved performance, efficiency, and engine combustion in the

appearance of flow. In this study, effects on a spark ignition...

The way in which position of spark plug affects combustion in a spark ignition engine can be analyzed by using two-zone burning model. The purpose of this paper is to extract correlations to simulate the geometric interaction between the propagating...
