By General Motors of Canada - Chevrolet Cruze customers can rest easy knowing the engineers who developed their car packed a wide variety of advanced fuel-saving technologies under the hood.One of those technologies is deceleration fuel cutoff (DFCO). While the vehicle is decelerating or slowing down, fuel is automatically shut off to the Cruze's advanced Ecotec engine. When the driver accelerates, the fuel automatically begins flowing again and the vehicle accelerates as the driver commands. It's a seamless process that the driver and passengers don't notice.
The benefits: This is an effective technology that helps keep money in a customer's pocket when at the pump.
"The Cruze is packed with fuel-saving technologies," said Kai Loos, the development systems manager for the Cruze's 1.4-litre turbocharged engine. "These types of cost-effective technologies allow Chevrolet to offer customers a vehicle that achieves hybrid-like efficiency without the cost of the hybrid technology."
How it works: DFCO is enabled when the driver's foot is off the accelerator pedal and the vehicle is coasting. Through integration of engine and transmission conrols, the engine speed is carefully controlled under these deceleration conditions. Fuel automatically begins flowing back to the engine when the driver accelerates or when the engine speed approaches idle conditions.
This technology is on Cruze models with both automatic and manual transmissions.
Cruze Eco with the standard six-speed manual transmission remains the most fuel-efficient gas-powered/non-hybrid vehicle in North America, with a rating of 4.6L/100km on the highway.
