In this study, a novel idea of capturing ion current signals inside the passive pre-chamber is
proposed. The signals were analyzed in terms of various operating conditions based on a …

In order to reduce fuel cost and CO2 emissions, modern spark ignition (SI) engines need to
lower as much as possible fuel consumption. A crucial factor for efficiency improvement is …

The paper presents the implementation of a combustion diagnosis system that integrates
crankshaft speed oscillations analysis with ion current signal processing, for V8 and V12 …

Compression ignition engines will continue to power heavy-duty, long-haul vehicles, and
heavy machinery in the future, while batteries become more prevalent in powering light-duty …

The cycle-to-cycle and cylinder-to-cylinder variations that occur in a spark ignited engine
create the opportunity for monitoring combustion in real time to provide useful benefits for …

This paper discusses the use of an ion current sensor to detect combustion resonance in a
heavy duty direct injection diesel engine. A modified glow plug is used to measure the ion …

Engine calibration becomes much more costly due to strict exhaust emission regulations
and individual consumer needs. Measuring the in-cylinder pressure could be a promising …

This paper presents a modelling study of the ion current formed in a direct-injection diesel
engine via chemical kinetics in order to investigate the strong correlation observed …

We present the first published record of electrical phenomena in the oxyfuel cutting torch
flame while cutting a steel work piece. Measurements of the voltage-current characteristic …

Electrical phenomena useful for oxy-fuel process sensing are demonstrated at signal level
voltages applied to an oxy-fuel cutting torch. The current-voltage characteristic of the flame …
