Cummins starts electric wastegate trials with ‘major OEM’ 19 January 2015

Cummins Turbo Technologies is working with a large unnamed OEM vehicle manufacturer, field testing its new, compact electric wastegate turbocharger for light- and heavy-duty engines.

Its new turbo technology, claimed to be suitable for engines from 3.8 to 16 litres, has been engineered to increase fuel efficiency of modern diesel engines, according to Jonathan Wood, executive director, research and engineering.

With its fast response and precise control throughout engine performance envelopes, it will help to improve performance and reduce emissions, he says.

"This is the first of our suite of next generation, post Euro 6 and EPA 13 technologies to move into field testing with customers, bringing us one step closer to production of this advanced technology," states Wood.

"The pioneering twin-port wastegate technology is exclusive to Cummins Turbo Technologies and was developed at our technical centre and manufacturing plant in Huddersfield," he adds.

For flexibility across heavy- and light-duty applications, the new electric wastegate offers two actuator options. Additionally, the twin-port design features an arrow-head lever, increasing the potential for wastegate flow bypass while retaining durability.

Essentially, this patented technology allows gas to bypass the turbine wheel from both volutes on twin entry housings, while the electric actuator matches the system to different applications by accurately controlling flow through the wastegate valve.
