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 gerotor-type oil pump was located at the bottom-rear of the engine, and provided oil to both the crankshaft main bearings and the cylinder heads (via the lifters and pushrods, as opposed to a bored passage on LA engines). Chrysler's engineers also redesigned the oil seals on the crankshaft to improve anti-leak seal performance.
2003–present: Hemi. 5.7L Hemi - The smallest modern Hemi engine, called the Eagle, introduced in 2002. 6.1L Hemi - A larger modern Hemi, 2004–2010. 6.4L Hemi - A larger bore modern Hemi engine, called the Apache, introduced in 2011. 6.2L Hemi - A supercharged Hemi engine, called the Hellcat, introduced in 2014.
The 1955 Dodge car lineup, consisting of the entry-level Coronet, Royal, and ornate Custom Royal, was a major departure for the company.Driven almost out of business in 1953 and 1954, the Chrysler Corporation was revived with a $250 million loan from Prudential and new models designed by Virgil Exner.
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.
