New developments in the area of fuel injection systems, ignition, valve train and ancillary systems will help European manufacturers of petrol engines meet growing demands for reduced CO2 and other tailpipe emissions without the cost and risk of radically different technologies, supplier Delphi said on Wednesday.

The new systems are part of its range of powertrain technologies for petrol, diesel, hybrid and alternative fuel vehicles.

"Our strategy is to help vehicle manufacturers meet their emissions targets at minimum cost and with minimal technical risk by offering a portfolio of both revolutionary and evolutionary technologies," said the component maker's powertrain systems engineering director for European petrol engines, Sebastian Schilling.

"Delphi's understanding of the interdependencies of systems at the whole vehicle level gives us tremendous insight into their interactions, helping us see where the most cost-effective benefits can be achieved and allowing us to support a wide range of emissions control strategies."

Technologies for gasoline engines on offer include port fuel injection, homogeneous and stratified gasoline direct injection (GDi) and compressed natural gas (CNG), new multi-charge ignition and the new electrically driven cam phaser (e-phaser).

"Whatever the engine technology strategy, we have systems that can simplify implementation, reduce costs and help deliver greater efficiency," claimed Schilling.
