Chrysler Group Launches All-New Line of Engines

Chrysler Group engineering will debut key technologies on the Chrysler Group version of the World Engine, co-developed by DaimlerChrysler, Hyundai Motor Company and Mitsubishi Motors Corporation under the Global Engine Manufacturing Alliance (GEMA).

“The Chrysler Group will deliver customer benefits with this series of engines, including significant refinements in sound quality, improvements in fuel efficiency, world-class horsepower and torque and reductions in noise, vibration and harshness,” said Eric Ridenour, Executive Vice President Product Development, Chrysler Group.

Technologies include dual Variable Valve Timing (VVT) and intake manifold design with flow control valves, both launching in the U.S. and Canada first in Chrysler Group versions of the World Engine.

Engines of three different displacements will be produced for the Chrysler Group: 1.8-litre, 2.0-litre and 2.4-litre. The horsepower and torque targets are among the best four-cylinder engines — 170 horsepower and 165 lb-ft of torque for the 2.4-litre.

The engines are targeted to raise the efficiency by 5 percent over the engines they replace and also enable the engine to meet the ultra-clean ULEV II emissions standards.

An isolated valve cover and a damped oil pan reduce sound at the top and bottom of the engine. A variety of select-fit parts minimize NVH. Engine idle smoothness is improved through dual VVT technology and the flow control valve intake manifold.

Hyundai initiated development of the program, and the Chrysler Group has made significant engineering contributions to the engine design.
