2011 Chevrolet Cruze Uses Special Oil Pump for Fuel Conservation

The 2011 Chevrolet Cruze uses a special oil pump to attain its impressive fuel conservation:

The oil pump in the engine of the 2011 Chevrolet Cruze takes a laid-back approach to its work, delivering the precise amount of oil needed during all driving conditions. That requires the engine to work less versus a conventional pump and ultimately saves fuel.

A standard feature in the Cruze’s Ecotec 1.4L turbocharged engine, the variable displacement oil pump reduces the displacement during engine warm up and high speed conditions. The volume of oil from the pump varies with rpm by changing the pump’s displacement through a pivoting control chamber mechanism and sliding vanes. A fixed displacement pump would typically bypass the extra oil internally.

“By lowering the volume of oil we reduce the amount of energy, or torque, required to pump the oil, without taking necessary lubrication away from the engine,” said Mike Katerberg, assistant chief engineer for the 1.4L. “Reducing the torque demand reduces fuel consumption. It’s a simple, durable, maintenance-free design that we have used in our transmissions for years and more recently in our hybrid vehicles.”
