 Hemi Grand Cherokee tulekul
The new Hemi engine will be available as an option in the upcoming redesigned 2005 Grand Cherokee. The 5.7-liter V-8, which puts out 345 horsepower with 375 lb.-ft of torque, debuts for model year 2003 in the new 1500, 2500 & 3500 Dodge pickups. As described by DC, "The engine's unique two-valve Hemispherical combustion chamber (which gives the engine its "Hemi" name) within an aluminum head provides impressive air flow, torque and power, and gives the engine its throaty rumble. Fifty-six pounds lighter than the 5.9-liter V-8, the 5.7-liter Hemi produces 41-percent more power and a 12-percent increase in peak torque." The engine started production at the Salitillo plant in Mexico in June of 2002. More than 35,000 engines per month have been rolling off the assembly lines. The engines will be used in pickups, Dakotas, Durangos and other large Chrysler vehicles.
Future versions of the Hemi engine will include Cylinder Deactivation, a feature which shuts down four of the eight cylinders during idling and light-demand situations, such as highway driving, by electronically controlling the flow of oil to valve lifters. Engines with this enhanced fuel-saving feature are slated to start production in January of 2004.
Facts and features:
The 5.7-liter Hemi® Magnum V-8 engine is an internally balanced pushrod (OHV) 90-degree V-8. The cast iron block is a deep skirt and cross-bolted design with cylinder bore spacing the same as the engine it replaces.
The aluminum cylinder features a two-valve per-cylinder, Hemispherical combustion chamber with dual spark plugs and a coil over plug ignition for best-in-class airflow and power. At an impressive 345 hp and 375 lb.-ft of torque, the 5.7-liter Hemi cranks out 41 percent more power and 12 percent greater torque than the 5.9-liter Magnum V-8 it replaces. And the power plant is 56 pounds lighter than its predecessor. An Integrated Air Fuel Module (IAFM) incorporates the function of 26 individual components in the induction and fuel system, thereby reducing cost, weight and engine plant complexity.
The 5.7-liter Hemi marks Chrysler Group's first application of an electronic throttle control system in a rear-wheel-drive vehicle. The system uses a DC motor with reduction gears to open and close the throttle, for optimal control of the airflow into the engine. A combination of the 5.7-liter Hemi and the new 545RFE five-speed automatic transmission will improve fuel efficiency by 8-10 percent over the 5.9-liter V-8.
A systematic approach to sealing, using premium elastomeric materials and state-of-the-art practices, helps ensure a leak-free, weep-free engine. The power plant's simple and efficient design means servicing and repairs are easier and less costly.

The 5.7 Hemi engine will become available this year as a crate engine both as carburated and stand alone EFI versions. The price should be about the same as that of LS1 crate engines. The only problem is, that there currently isn't an easily available RWD transmission set up for the engine; it's got its own bellhousing bolt pattern. And just a personal opinion; the looks of that engine does not impress me. |

Dodge Durangod ja RAMid veerevad m88da t2navaid juba nende mootoritega.
Peale Hemit pidavat oluline muudatus olema ees s6ltumatu vedrustus, kuna turg seda n6uab.

Minu mälu järgi on kõik teise põlve Grand Cherod (alates '99 siis) sõltumatu vedrustusega ees ju? |

Esimene s6ltumatu vedrustusega esisillaga Jeep peaks ikka 2002 Liberty/Cherokee (KJ) olema.
