  2. Multi-Displacement System - Wikipedia

    en.wikipedia.org/wiki/Multi-Displacement_System

    Chrysler's Multi-Displacement System (MDS) is an automobile engine variable displacement technology. It debuted in 2005 on the 5.7 L modern Hemi V8.Like Mercedes-Benz's Active Cylinder Control, General Motors' Active Fuel Management, and Honda's Variable Cylinder Management, it deactivates four of the V8's cylinders when the throttle is closed or at steady speeds.

  3. Chrysler Hemi engine - Wikipedia

    en.wikipedia.org/wiki/Chrysler_Hemi_engine

    Chrysler developed its first experimental hemi engine for the Republic P-47 Thunderbolt fighter aircraft. The XIV-2220 was an inverted V16 rated at 2,500 hp (1,860 kW). The P-47 was already in production with a Pratt & Whitney radial engine when the XIV-2220 flew successfully in trials in 1945 as a possible upgrade, but the war was winding down and it did not go into production.

  4. Hemispherical combustion chamber - Wikipedia

    en.wikipedia.org/wiki/Hemispherical_combustion...

    A hemispherical head ("hemi-head") gives an efficient combustion chamber with minimal heat loss to the head, and allows for two large valves.However, a hemi-head usually allows no more than two valves per cylinder due to the difficulty in arranging the valve gear for four valves at diverging angles, and these large valves are necessarily heavier than those in a multi-valve engine of similar ...

  5. Ram pickup - Wikipedia

    en.wikipedia.org/wiki/Ram_pickup

    The Hemi 5.7L engine was dropped (except only Mexico-market Ram 4000), and the Hemi 6.4L becomes the base engine. For 2500 and 3500 pickups with the 6.4L, a ZF 8HP75-LCV 8-speed automatic is mated. The 6.7-liter Cummins turbo-diesel returns in both Standard and High-Output form, but with a new compacted graphite iron (CGI) block.

  6. Chrysler RFE transmission - Wikipedia

    en.wikipedia.org/wiki/Chrysler_RFE_transmission

    The 45RFE was introduced in the Jeep Grand Cherokee in 1999, it is notable for including three planetary gearsets rather than the two normally used in a 4-speed automatic. It also features three multiple disc input clutches, three multiple disc holding clutches, and a dual internal filter system (one primary filter for transmission sump, one for the fluid cooler return system).

  7. Chrysler Hemi-6 Engine - Wikipedia

    en.wikipedia.org/wiki/Chrysler_Hemi-6_Engine

    The Hemi-6 is a pushrod O.H.V. (overhead valve engine), with combustion chambers comprising about 35% of the top of the globe. This creates what is known as a low hemispherical shaped chamber. In this way, the "Hemi" moniker was used for the same kind of marketing cachet as Chrysler's 1950s-1970s Hemi V8 engines.

  8. Chrysler Slant-6 engine - Wikipedia

    en.wikipedia.org/wiki/Chrysler_Slant-6_engine

    Since 1972 Chrysler had not offered a 6 cylinder with sports aspiration but that would change with the release of the Dodge Polara RT, it was a hard top coupe equipped with the new high-performance Slant Six RG 225 or commonly known as Slant Six RT, thanks to the addition of a new Holley 2300 two-barrel carburetor, "3a1" exhaust manifolds, a ...

    The SRT Demon is also capable of accelerating at 1.8 G's of force at launch. [50] The boost pressure of the supercharger can be increased to 14.5 psi (100 kPa; 1.00 bar) and redline up to 6,500 rpm. With this extreme power, and hard acceleration, the SRT Demon is the first production car to perform a wheelie. [51]
