As Chevrolet gears up to launch the diesel-burning Chevy Cruze TD in the U.S., engineers responsible for adapting the 2.0 liter turbo-diesel engine (LUZ) to U.S. specifications were tasked with testing and adjusting it in four primary areas, including emissions, diagnostics, outside environmental conditions, and altitude.
The resulting improvement for the US-spec Cruze TD include a new intake manifold and throttle body system along with an increased capacity exhaust gas recirculation (EGR) cooler that offers better emissions control. Other improvements involve the common rail piezo injection system, which runs at 1,600 bar (European runs at 2,000 bar), along with the addition of ceramic glow plugs (European customers get metal glow plugs). And for those really cold winter mornings, the Cruze TD offers an engine oil heater that can be plugged in.
Unfortunately, all of these improvements to the North American version result in a decreased power output: the estimated pony count of the 2.0-liter diesel in the US is 148 horsepower, but its European
cousin brother makes 163.
As you might already know, the Cruze will be GM’s first passenger car to run on diesel since the Chevette did back in 1986… only that the Cruze is a far nicer car than the Chevette ever hoped to be.Google+
