DaimlerChrysler claims best-in-class performance for 2005 Jeep Liberty Diesel
Detroit, Michigan – The 2005 Jeep Liberty with a 2.8-litre turbocharged Common Rail Diesel (CRD) four cylinder engine has best-in-class torque, driving range and towing capacity, claims DaimlerChrysler.
The 2.8-litre CRD offers 295 lb-ft of torque (400 Nom) @ 1,800 rpm; a driving range of approximately 800 km, and towing capacity of 2268 kg (5,000 pounds). The engine produces 160 horsepower and gets an estimated fuel economy of 22 mpg U.S. (10.6 L/100 km) in the city, and 27 mpg U.S. (8.7 L/100 km).
“The 2.8-litre CRD is among today’s advanced diesel engines that emit 60 percent less emissions than diesel engines of 20 years ago,” said Craig Love, Vice President – Rear Wheel Drive Product Team and Core Team Leader. “Additionally, the noise, vibration and harshness issues that plagued older diesel-powered vehicles have been dramatically reduced in the Liberty diesel. The result is that the legendary capability of the Jeep Liberty reaches a new level of performance with the 2.8-litre diesel engine.”
The 2.8-litre CRD is an enhanced version of the four-cylinder diesel engine currently offered on this vehicle in Europe. VM Motori, which is owned in part by Detroit Diesel, a DaimlerChrysler company, is the manufacturer of the engine. VM Motori has been supplying the Chrysler Group diesel engines since 1992 for minivans and Jeep products sold in Europe.
The 2.8-litre diesel uses an advanced common rail direct injection fuel system. Direct injection of fuel into an open combustion chamber is more efficient than a pre-chamber indirect injection configuration. The system in the 2.8-liter CRD operates at fuel pressures nearly 70 percent above the older distributor pump systems, producing finer atomization, leaner combustion and higher power.
As well, the 2.8-litre diesel uses electronically controlled ceramic “smart” glow plugs with a warm-up time of only two seconds. They assist with low ambient temperature start conditions and only glow when needed. This is an advance over older, timer-operated glow plugs that require up to 10 seconds of warm-up prior to engine start.
The 2005 Jeep Liberty also features a new six-speed manual transmission, replacing two five-speed manual transmissions previously used in the Liberty. The six-speed transmission is similar to the one used in the Chrysler Crossfire, the first six-speed for the Chrysler brand.
