An improved spark ignition model has been developed and implemented into the KIVA-3V code. In this model, the spark ignition kernel growth is tracked by Lagrangian particle markers. The effects of turbulent flow and spark discharge energy on the kernel growth are considered. After the ignition kernel size exceeds a critical size related to the integral turbulent length scale of the flow, the tu...

The purpose of this study is to determine the largest and smallest power values maximum change in BMEP on influence shape spark plug electrode tip a 150 cc motorcycle engine. This applies laboratory experiments as research method with open full-throttle test method. increased for each standard plugs yields highest 6.64 kW at 6000 rpm lowest 2000 2.04 kW. While spherical iridium produces 2.09 rp...

This paper presents the design, applications, and performance of the miniature fiber optic-based cylinder pressure sensor which has targeted advanced engine controls requiring high accuracy pressure information. Three types of sensor packages are described currently utilized in prototype closed loop control systems for diesel, gasoline, and dual fuel engines: glow plug with the heater-mounted s...

The examination and choice of an alternate composite material for the high-voltage circuit Otto cycle internal combustion engines—more commonly known as gasoline engines—are presented in research that follows. To do this, multicriteria selection procedures are employed, outcomes validated through use thermal character simulation software standard laboratory tests. Nylon is recommended Coils on ...

Fundamental studies on laser ignition have been performed by the US Department of Energy under ARES (Advanced Reciprocating Engines Systems) and by the California Energy Commission under ARICE (Advanced Reciprocating Internal Combustion Engine). These and other works have reported considerable increases in fuel efficiencies along with substantial reductions in green-house gas emissions when emp...

the application of ion current signals is one of the most recent approaches in engine management systems. by applying a small constant dc voltage across the electrodes of the spark plug and measuring the current through the electrode gap, the state of gas may be measured and investigated. in this paper a computer code is developed in order to analyze the state of gas during the combustion perio...
