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 original multi-displacement system turned off opposite pairs of cylinders, allowing the engine to have three different configurations and displacements. The cars had an elaborate diagnostics procedure, including showing engine trouble codes on the air conditioning display.
Daimler AG's Active Cylinder Control (ACC) is a variable displacement technology. It debuted in 2001 on the 5.8 L V12 in the CL600 and S600.Like Chrysler's later Multi-Displacement System, General Motors' Active Fuel Management, and Honda's Variable Cylinder Management, it deactivates one bank of the engine's cylinders when the throttle is closed.
Active Fuel Management (formerly known as displacement on demand (DoD)) is a trademarked name for the automobile variable displacement technology from General Motors. It allows a V6 or V8 engine to "turn off" half of the cylinders under light-load conditions to improve fuel economy .
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.
Unlike the pushrod systems used by DaimlerChrysler's Multi-Displacement System and General Motors' Active Fuel Management, Honda's VCM uses overhead cams. A solenoid unlocks the cam followers on one bank from their respective rockers, so the cam follower floats freely while the valve springs keep the valves closed. The system operates through ...

If a large amount of storage is not practical, a variable-displacement system can be very effective, especially at greater than 70% of full load. [21] One way that variable displacement may be accomplished is by using multiple lifting valves on the suction side of the compressor, each plumbed to a corresponding location on the discharge.
