Last time the 2014 Chevrolet Cruze Clean Diesel came into our news GM was bragging about the vehicle's musclecar-like torque by comparing the new diesel with the not so brawny Camaros of the 1970s. We had some laughs and moved along...
Now, Chevy is back to brag about the Cruze Diesel some more. In fact, they just popped in to tell us more about their advanced 2.0-liter engine that uses a variable-swirl intake system which helps enhance performance and reduce CO2 emissions. As Chevrolet puts it, "each cylinder has two separate intake ports, with one of them controlled by a valve". During the "perfect storm", the valve varies how much it opens to create mixture-motion of air and fuel within each cylinder.
"Variable swirl helps put the 'clean' in Cruze Clean Turbo Diesel. It increases the mixture-motion of air and fuel in low-speed, low-load driving, like when you're doing the commuter crawl to work every day," Mike Siegrist, 2.0L turbo diesel assistant chief engineer, explains.
"It contributes to Cruze Diesel's great fuel economy, and helps give drivers the most torque for the least amount of fuel at the lowest emission and noise levels. All combustion engines have swirl, but having variable swirl is a real difference maker for Cruze's diesel engine. Ultimately, it means more driving satisfaction with less environmental impact," he adds.
The 2014 Chevrolet Cruze Clean Diesel returns and EPA-estimated 46 miles per gallon on the highway.
