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

Интеллект. 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

Extending Lean Operating Limit and Reducing Emissions of Methane Spark-Ignited Engines Using a Microwave-Assisted Spark Plug

Journal of Combustion, 2012
A microwave-assisted spark plug was used to extend the lean operating limit (lean limit) and reduce emissions of an engine burning methane-air. In-cylinder pressure data were collected at normalized air-fuel ratios of λ=1.46, λ=1.51, λ=1.57, λ=1.68, and ...
