What Does The New Cruze TD and a Tornado Have In Common?

A variable spin of course ;) The all-new 2014 Chevrolet Cruze Clean Turbo Diesel?s advanced 2.0L engine uses a variable-swirl intake system like most intakes nowadays to create what GM is calling a ?perfect storm? of fuel and air. In 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. General Motors? Powertrain team devoted countless hours to calibrating the actuator to precisely open and close the valves for optimal performance at varying loads.
