Federal-Mogul to unveil new ignition technology for fuel efficiency

ABR Staff Writer Published 14 September 2011

Federal-Mogul will introduce its Advanced Corona Ignition System (ACIS), a technology for fuel efficiency and emissions reduction that the company says significantly outperforms conventional spark-ignition systems.

The company is currently developing the ACIS technology in association several customers, and it is claimed to deliver up to 10% fuel efficiency improvement over standard spark ignition in development testing.

Unlike conventional spark ignition systems, Corona ignition creates a significantly larger high-intensity plasma ignition source, spread throughout the combustion chamber.

The new technology provides for more thorough combustion and enables advanced combustion strategies like lean burn, highly diluted mixtures and very high exhaust gas recirculation (EGR).

ACIS uses a high-energy, high frequency electrical field to produce repeatable, controlled ionization, creating multiple streams of ions to ignite the fuel mixture throughout the combustion chamber.

It generates rapid ignition and quick burning, ensuring greater conversion of the fuel energy to mechanical energy with the added potential for simultaneous reduction in engine cooling requirements.

Federal-Mogul director, advanced corona ignition system development, Powertrain Energy, Kristapher Mixell said Corona ignition technology provides higher energy and greater opportunities for ignition than a spark-ignition system, readily accommodating different fuel characteristics.

"The technology enables powertrain engineers to more efficiently develop combustion strategies, such as stratified charge, lean burn and high levels of EGR, to reduce fuel consumption exhaust emissions," Mixell said.

The new technology features a "two-piece" igniter architecture that allows engine manufacturers the ability to replace traditional coil and plug systems with no adverse impact on engine design or assembly, the company said.

The company is developing its ACIS at its technical centers in the US, Europe and Asia.
