MT. PLEASANT, Mich. -- The 2019 Chevrolet Silverado 1500 will feature the most advanced gasoline V-8 engines in the brand's history: updated versions of their proven 5.3L and 6.2L V-8s with Dynamic Fuel Management. An industry-first, this innovative cylinder deactivation technology enables the engines to operate in 17 different cylinder patterns to optimize power delivery and efficiency.
“Chevrolet first introduced its Active Fuel Management cylinder deactivation system in 2005, and Dynamic Fuel Management is a natural progression of the technology,” says Jordan Lee, Small Block chief engineer. “Dynamic Fuel Management enables only the cylinders needed to deliver the power you want, seamlessly delivering the best balance of power and fuel economy.”
Compared to the current Active Fuel Management, which alternates between eight and four-cylinder modes, Dynamic Fuel Management features 17 cylinder patterns, which mixes them constantly to optimize efficiency and power delivery at all speeds.
During an industry-standard test schedule, the 2019 Silverado 2WD featuring the 5.3L engine with Dynamic Fuel Management operated with fewer than eight active cylinders more than 60% of the time, which is about 9% more than a comparably equipped 2018 model with Active Fuel Management.
Dynamic Fuel Management utilizes an electromechanical system that deactivates and reactivates all 16 of the engine's hydraulic valve filters, controlling valve actuation. This system uses solenoids to deliver oil pressure to control ports in the lifters, which activate and deactivate the lifters' latching mechanisms. During deactivation of a cylinder, the two-piece lifters collapse on themselves to prevent valve opening. During reactivation, solenoids send an oil pressure signal to the control ports on the lifters and latching mechanisms to restore them to normal function, allowing the valves to open and close.
“The increased variability of Dynamic Fuel Management means the engine will operate more often with a reduced number of cylinders, which saves fuel across the board,” says Lee. “Better yet, the transitions are transparent, and because the system is torque-based, you’ve always got that satisfying feeling of power on demand that comes from Chevy’s Gen V Small Block V-8 engines.”
The 5.3L V-8 with Dynamic Fuel Management is SAE-certified at 355 horsepower and 383 lb. ft. of torque, and is matched with a Hydra-Matic eight-speed automatic transmission.
The 6.2L V-8 with Dynamic Fuel Management - the largest and most powerful gas V-8 in the segment - is SAE-certified at 420 horsepower and 460 lb. ft. of torque, and is matched with a Hydra-Matic 10-speed automatic transmission.
Both transmission feature significant enhancements designed to improve shift quality, as well as a new centrifugal pendulum absorber torque converter that reduces vibrations during cylinder deactivation to improve smoothness.
The new Dynamic Fuel Management engines also feature optional stop/start technology that helps to conserve fuel in stop-go traffic. The 5.3L engine comes standard in the LTZ and High Country models and is available on the LT, RST, and Trail Boss. The 6.2L engine is also available in the LZT and High Country.
The all-new 2019 Chevrolet Silverado hits showrooms this fall. EPA fuel economy ratings are not yet available and will be closer to launch.
