Unique Oil Pump Aids Chevy Cruze Preserve Gas

The oil pump inside the engine on the 2011 Chevy Cruze has a laid-back strategy to its work, delivering the complete quantity of oil needed during all driving conditions. That will require the engine to operate less versus the standard pump and ultimately saves fuel.
A regular feature inside the Cruze’s Ecotec 1.4L turbocharged engine, the variable displacement oil pump cuts down on the displacement during engine warm-up and top speed conditions. The quantity of oil on the pump varies with rpm by modifying the pump’s displacement via a pivoting control chamber system and sliding vanes. A restricted displacement pump would normally bypass the additional oil internally.

“By lowering the quantity of oil we reduce the quantity of energy, or torque, needed to pump the oil, without taking necessary lubrication from the engine,” said Mike Katerberg, assistant chief engineer for your 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.”

The Ecotec 1.4L turbo is regular on Eco, LT and LTZ models helping the Cruze Eco, using a normal six-speed transmission, obtain an expected segment-leading estimated 40 mpg on the road.

The advantages of the variable displacement oil pump boost when combined with other technologies like variable valve timing which operate using oil pressure. Variable valve timing adjusts the engine valves’ buying and selling timing for optimal performance, fuel efficiency and emissions through the rpm band – including greater low-rpm torque.

The all-new 2011 Chevrolet Cruze will start arriving in U.S. dealerships this September, starting at $16,995, including destination. Priced to compete in the compact-car segment, the Cruze provides more interior room, more miles per gallon in the Eco model, and much more standard security features than any of its competitors.
