“…Besides, from the results of testing the kernel, IMEP (Indicated mean effective pressure), and response based on three plasma energies, it could be noticed that the combustion reaction is quickly promoted by higher energy [12]. Besides, we have physically proved that MEHV has positive effects on progressive combustion, including the lean burn characteristics [13], flame thickness and velocity, and combustion flame propagation [14].…”

The characteristics of spark ignition with a constant volume combustion chamber (CVCC) is evaluated for the efficiency of capacitive-assisted ignition (CAI), such as spark kernel and flame growth. The conventional spark method and matching effect of high voltage (MEHV) method are evaluated to compare the spark growth distribution characteristics. To do this study, a plasma system is used and is consisted of input power, three capacitors, a transformer, high voltage cable, J-type of a spark plug, diode, and CVCC. The experiment is conducted under various operating conditions, such as 1 bar, 295 K of initial temperature, 50, 100, 150 V of ignition box, 400 V of MEHV, 0.7 ms of spark duration, and 0 kΩ of plug resistor. The results show that the spark growth at the initial voltages of 100 V and 150 V has the same characteristic, and the surface area is increased by 13 mm2 at 150 V compared to 100 V because capacitance energy stored in three capacitors is efficiently induced by the effect of dielectric breakdown and electron collision. Consequently, the spark growth of MEVH is widely distributed atmospheric more than the conventional spark, and the internal temperature of the spark kernel could be presumed to change the non-thermal plasma to thermal plasma by MEHV.

This work reviews the impact of carbon dioxide (CO 2 ) on laminar burning speed and stability of the flame for methane (CH 4 ) and propane (C 3 H 8 ) combustion with air. Mixtures of CH 4 and CO 2 , also known as biogas, are considered as low-cost alternative fuels. Biogas is widely used in various industrial and residential applications. Mixtures of C 3 H 8 and CO 2 are considered as alternative refrigerants with low global warming potential and low flammability. Laminar burning speeds were reported using different experimental methods. Laminar burning speeds have also been numerically calculated by onedimensional steady code using three chemical kinetic mechanisms. Results depict a decrease in equilibrium flame temperature and laminar burning speed of both CH 4 /air and C 3 H 8 /air mixtures with the existence of CO 2 in those mixtures. The maximum laminar burning speeds of neat CH 4 and C 3 H 8 are observed to be in the vicinity of an equivalence ratio of 1.1; however, as the percentage of CO 2 increases, the maximum laminar burning speeds shift toward stoichiometric mixtures. Carbon dioxide also increases flame thickness and suppresses flame instability by the combination of thermal-diffusive and hydrodynamic effects.

“…This result has demonstrated that the output signal is relatable with the simulation results. From the oscilloscope, it is measured that the signal frequency is 100 Hz, and the amplitude of the signal is 160 V. By using the transformer amplification factor data from the experiment, ignition coil output voltage can be determined using (5).…”

This paper presents an alternative solution for generating ozone using a low-cost automotive Capacitive Discharge Ignition (CDI) coil. High voltage ozone generating theory is implemented using a capacitive discharge circuit that uses ignition coil as its high voltage step-up transformer. A computer simulation has been performed to confirm the validity of the circuit function. By calculation and measurement, the coil has 196,71 voltage amplification factor. Furthermore, it has been implemented at a low frequency of about 10 - 40 Hz. Meanwhile, ozone output is measured using the colorimetric method. From a series of tests, that coil implementation has successfully generated a high voltage on ozone reactor tube at 31.47 kV voltages that essential for ozone production. Change of frequency will change the ozone concentration output linearly. The test was conducted using three different frequency: 10 Hz, 20 Hz, and 40 Hz. The result has shown that the highest ozone yield was 80 mg/hour.
