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 ...
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.
The Chrysler B and RB engines are a series of big-block V8 gasoline engines introduced in 1958 to replace the Chrysler FirePower (first generation Hemi) engines. The B and RB engines are often referred to as "wedge" engines because they use wedge-shaped combustion chambers; this differentiates them from Chrysler's 426 Hemi big block engines that are typically referred to as "Hemi" or "426 Hemi ...
The 5.9 L Magnum was available until the 2003 model year, when it was replaced with the 5.7 L Hemi V8 engine. [ 18 ] Although the pre-Magnum (1971–92) and Magnum versions of the 360 cu in (5.9 L) are both externally balanced, the two are balanced differently (the Magnum version uses lighter pistons) and each requires a uniquely balanced ...
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.
The V family is often referred to as the "Toyota Hemi" [citation needed] as the engine features a cylinder head design with approximately hemispherical combustion chambers. Code Capacity
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.
The 4.7-liter version was the first of this family, appearing in the 1999 Jeep Grand Cherokee.The displacement is 4.7 L; 286.7 cu in (4,698 cc) with a bore and a stroke of 3.66 in × 3.405 in (93.0 mm × 86.5 mm).
