The Chrysler EZB or HEMI 5.7 5.7-liter V8 engine was produced in Mexico from 2004 to 2008 and was installed on top versions of well-known models such as the 300C, Charger or Grand Cherokee. This power unit was equipped with an MDS half-cylinder off-load system.
The Chrysler HEMI 5.7 EZB engine features a cast-iron block and two aluminum heads with hemispherical combustion chambers, a single camshaft (OHV), and two valves per cylinder (16 valves in total). The Chrysler HEMI 5.7 engine used an electronically-controlled Sequential Multi-Port Electronic Fuel Injection system, distributorless, coil over plug ignition system with two spark plugs per cylinder and Multi-Displacement System (MDS), which enabled the engine to switch from eight to four-cylinder operation.
HEMI family: EZA, EZH, ESF, ESG, EZB, ESD, ESJ.
