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 present study experimentally investigates the effect of metal oxide nanoparticles on the ignition probability, ignition zone, and burning time of the diesel fuel. For this purpose, a series of hot plate ignition tests are conducted on the diesel...

to be a promising renewable energy that can be used on IC engines. In this paper an evaluation and assessment of numerical and experimental investigations on performance and exhaust emission with hydrogen added to a spark ignited gasoline engine fuelled...

The performance of a spark ignition engine is investigated under different values of ignition advance. A two-zone burnt/unburned model with the fuel burning rate described by a Wiebe function is used for modeling in-cylinder combustion...

To improve the engine performance and reduce emissions, factors such as changing ignition and injection timing along with converting of port injection system to direct injection in SI(spark-ignited) engines and hydrogen enrichment to CNG fuel at WOT...

in cylinder wall. An eddy break-up combustion model and a diesel auto-ignition model were implemented to simulate the ignition and combustion process. All the simulations were carried out by the use of FIRE CFD tool. Numerical results were validated via...

in the ignition of hydrocarbons with only a few percent

addition of hydrogen by volume and by adding it to the pure natural gas (CNG)

this difference in spark advance of the engine may be reduced, as a result of the

higher flame speed...
