Multi-Displacement System
Chrysler's Multi-Displacement System (MDS) is an automobile engine variable displacement technology. It debuted in 2006 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 system was first offered only on passenger cars, since the heavy demands of trucks would interfere with its operation. However, it was recalibrated for 2006 and was offered on all seven models, including SUVs and 1500 series trucks, using the 5.7 L engine. Chrysler expected that the technology would boost economy by 10% to 20%. In the Jeep Grand Cherokee with MDS, highway fuel mileage for the V8 is the same as the V6 at 21 mpg (11.2 liters per 100 km). In order to preserve the characteristic rumble of the V8 engines, Chrysler and Eberspaecher North America designed a special exhaust system for ...

Displacement On Demand
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. Estimated performance on EPA tests shows a 5.5–7.5% improvement in fuel economy. GM's current Active Fuel Management technology uses a solenoid to deactivate the lifters on selected cylinders of a pushrod V-layout engine. Third generation In January 2018, GM announced an improved version of AFM called ''Dynamic Fuel Management'' to be initially released in Chevy Silverado trucks. This system shuts off any number of cylinders in a variety of combinations, maximizing fuel economy and avoiding switching between banks of cylinders . The system is based on ''Dynamic Skip Fire,'' a technology developed by California company Tula Technology. The 6.2L V8 engine of the Chevrolet Silverado incorporating ...

Dodge Challenger
The Dodge Challenger is the name of three different generations of automobiles (two of those being pony cars) produced by American automobile manufacturer Dodge. However, the first use of the Challenger name by Dodge was in 1959 for marketing a "value version" of the full-sized Coronet Silver Challenger. From model years 1970 to 1974, the first generation Dodge Challenger pony car was built using the Chrysler E platform in hardtop and convertible body styles sharing major components with the Plymouth Barracuda. The second generation, from model years 1978 to 1983, was a badge engineered Mitsubishi Galant Lambda, a coupe version of an economical compact car. The third and current generation is a pony car that was introduced in early 2008 originally as a rival to the evolved fifth generation Ford Mustang and the fifth generation Chevrolet Camaro. In November 2021, Stellantis announced that 2023 model year would be the final model year for both the Dodge Charger and Dodg ...

V12 Engine
A V12 engine is a twelve-cylinder piston engine where two banks of six cylinders are arranged in a V configuration around a common crankshaft. V12 engines are more common than V10 engines. However, they are less common than V8 engines. The first V12 engine was built in 1904 for use in racing boats. Due to the balanced nature of the engine and the smooth delivery of power, V12 engines were found in early luxury automobiles, boats, aircraft, and tanks. Aircraft V12 engines reached their apogee during World War II, following which they were mostly replaced by jet engines. In Formula One racing, V12 engines were common during the late 1960s and early 1990s. Applications of V12 engines in the 21st century have been as marine engines, in railway locomotives, as large stationary power as well as in some European sports and luxury cars. Design Balance and smoothness Each bank of a V12 engine essentially functions as a straight-six engine, which by itself has perfect primary and ...
