Are Americans ready for affordable diesel engines? Chevy thinks they are with its 2014 Chevy Cruze. The new model has a 2.0/151-hp/264lb-ft DOCH16-valueturbodiesel I-4 engine, which uses a variable-swirl intake system to create a “perfect storm” of air and fuel that enhances performance while helping to reduce emissions.
In addition is Cruze’s variable-swirl intake manifold, each cylinder has two separate intake ports, with one of them controlled by a valve. During variable swirl, each throttle 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,” said Mike Siegrist, 2.0L turbo diesel assistant chief engineer. “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.”
Cruze’s clean diesel engine offers a segment-leading EPA-estimated 46 mpg highway and range of more than 700 miles per tank and the diesel engine combined with an automatic transmission, provides greater fuel economy than a comparably sized gasoline engine through greater thermal efficiency, a higher compression ratio and an unthrottled combustion process, and is considered the cleanest diesel engine ever produced by GM.
In general, clean diesels generate at least 90 percent less Nitrogen Oxide (NOx) and particulate emissions when compared to previous-generation diesels. Cruze Clean Turbo Diesel’s emissions will meet U.S. Environmental Protection Agency’s (EPA) stringent Tier 2 Bin 5 emissions standards.
“All combustion engines have swirl, but having variable swirl is a real difference maker for Cruze’s diesel engine,” Siegrist said. “Ultimately, it means more driving satisfaction with less environmental impact.”
GM’s addition of the 2014 Chevy Cruze with its additional power and efficiency which beats anything on the road today and a formula which has been proven worldwide sets, a higher bar and will temp the American consumers to try Diesel power.
