Full-size sport-utility car outfitted with 3.0-liter frequent rail turbo diesel
Up to 30 % enchancment in gas economic system
Class-leading towing, torque and driving vary
First use of Piezo injection in a North American SUV
The Chrysler Group introduced on June 1st, 2006 its plans to supply its first diesel-powered, full-size sport-utility car (SUV) to be provided within the United States. The 2007 Jeep® Grand Cherokee with a 3.0-liter frequent rail turbo diesel (CRD) engine will arrive at Jeep dealerships within the first quarter of 2007.
“DaimlerChrysler is a pacesetter in automotive diesel functions in Europe, and it is smart to proceed to construct on that have by providing a contemporary, clear diesel for the U.S. market,” mentioned Craig Love, Vice President — Rear-Wheel-Drive Product Team, Chrysler Group. “The Jeep Grand Cherokee diesel will supply shoppers elevated gas economic system, class-leading torque, towing and driving vary.”
The new 3.0-liter CRD engine, constructed by Mercedes-Benz, produces 215 hp (160 kW) @ 3800 rpm and 376 lb.-ft. torque (510 N•m) @ 1600-2800 rpm and will get an estimated gas economic system of 19 miles metropolis and 23 miles freeway. The 2007 Jeep Grand Cherokee CRD provides class-leading torque, excellent towing capability (7,400 lbs.), and class-leading driving vary of roughly 425 miles. And, clear diesel know-how improves gas economic system by as much as 30 % and has as much as 20 % fewer carbon dioxide (CO2) emissions. The 3.0-liter CRD engine can be accessible on the Jeep Grand Cherokee Laredo, Limited and Overland fashions.
“The 3.0-liter CRD is an environment friendly, smooth-running, clear engine that delivers gas economic system and efficiency,” mentioned Bob Lee, Vice President — Power Train Product Team, Chrysler Group. “Advanced diesel know-how has improved over the past a number of years; engines are quieter and cleaner attributable to digital controls, larger gas pressures and superior after-treatment techniques.”
More than 60 % of Chrysler Group autos offered in Western Europe are diesel-powered. Between 2003 and 2007, Chrysler Group will triple the variety of diesel choices outdoors North America. Of the estimated 20 autos accessible, 12 or extra may have the choice for a diesel powertrain (up from 4 in 2003).
The Jeep Grand Cherokee CRD can be manufactured on the Jefferson North Assembly Plant in Detroit. The 3.0-liter CRD engine is constructed on the Mercedes-Benz Berlin Marienfelde Plant in Berlin, Germany. Pricing can be introduced nearer to availability.
The frequent rail direct-injection system has been refined, attaining larger progress in gas consumption, exhaust emissions and combustion noise. Newly developed Piezo injectors function extra quickly than the earlier solenoid injectors, making certain a exactly metered gas provide to the cylinders. Piezo injectors are managed for load and engine pace. Five injections per energy stroke are actually attainable at a peak stress of as much as 24,000 psi.
Electrically actuated intake-port swirl valves modifies the turbulence of the consumption air because it enters the cylinders, optimizing the combustion course of with the purpose of additional decreasing gas consumption and exhaust emissions. The new digital management unit (ECU) manages all of the engine capabilities – from the quick-start glow system and computerized begin perform to regulate of the high-pressure gas pump.
The turbocharger, a Variable Geometry Turbine (VGT) with electrically adjustable blades, acts like a small turbocharger underneath launch circumstances, however has the fascinating traits of a bigger turbocharger at larger engine speeds. The profit to prospects is enhanced response at low engine speeds.
