Chaotic Combustion in Spark Ignition Engines [PDF]

open access: yes, 2002
We analyse the combustion process in a spark ignition engine using the experimental data of an internal pressure during the combustion process and show that the system can be driven to chaotic behaviour. Our conclusion is based on the observation of unperiodicity in the time series, suitable stroboscopic maps and a complex structure of a reconstructed ...

Experimental and Numerical Study of the Flammability Limits in a CH4/O2 Torch Ignition System

open access: yesEnergies, 2022
The current work is devoted to studying combustion initiation inside the methane-oxygen torch igniter for a hybrid rocket motor. The ignition system can generate a wide range of power and oxidizer-to-fuel ratios.

Modeling of Internal Combustion Engine Ignition Systems with a Circuit Containing Fractional-Order Elements

open access: yesEnergies, 2022
This paper discusses the research and analysis of the dynamics of high-voltage generating systems. The test subject is an ignition system modelled by a set of two induction coils with an open ferromagnetic core that constitutes an ignition coil.

Substantiation of the method for diagnosing the ignition system of automobile petrol engines by exhaust gas toxicity parameters in individual cylinders

open access: yesИнтеллект. Инновации. Инвестиции, 2022
It is known that the proportion of failures of the elements of the power supply system of automobile piston engines reaches 45% of all its failures, including 9% of cases are failures of the elements of the ignition system. An analysis of this statistics

Signal Processing of Acoustic Data for Condition Monitoring of an Aircraft Ignition System

open access: yesMachines, 2022
Degradation of the ignition system can result in startup failure in an aircraft’s auxiliary power unit. In this paper, a novel acoustics-based solution that can enable condition monitoring of an APU ignition system was proposed.

The influence of impurities on the operation of selected fuel ignition systems in combustion engines

open access: yesArchives of Electrical Engineering, 2016
The paper attempts to determine the impact of fuel impurities on the spark discharge energy and the wear of the spark plug electrode. Spark plugs were analyzed in two typical configurations of the ignition system.

Experimental Assessment of Primer Pressure in 9 mm Pistol Ammunition [PDF]

open access: yesProblemy Mechatroniki, 2020
In theoretical simulations of internal ballistics phenomena, the value of pressure generated by the ignition system is required. Typically, the ignition pressure value is assumed to be 3 - 5 MPa.
