The 2019 Silverado's Dynamic Fuel Management Factor: an Industry-First Feature



As the summer months make their way into Missouri, thoughts may turn to lake trips, camping, and more hours of sunlight to get whatever hard job is on your itinerary done. One of the vehicles we are asked about most here at the Mid-Missouri Powerhouse is the all-new for 2019 Silverado 1500, as rugged, awesome, and powerful as it is, there is now another fantastic feature that will draw many customers to it. The new Silverado will now offer the most advanced gasoline V-8 Engine in the brand's history, with newly-updated versions of the 5.3-liter and 6.2-liter V-8s featuring this asset. What this revolutionary technology does is enables the engines to operate in 17 different cylinder patterns, which goes to work on power delivery effectiveness, and overall efficiency.

Small Block chief engineer Jordan Lee was asked to comment on the process effectiveness level, and quoted, “Dynamic Fuel Management enables only the cylinders needed to deliver the power you want, seamlessly delivering the best balance of power and fuel economy”. One of the most amazing components of this system is the electromagnetics: they are responsible for deactivating and reactivating all 16 of engine's hydraulic valve lifters, controlling the patterns in which they actuate. When a cylinder in this system is activated, the two-piece lifters use energy to collapse on themselves, which prevents them for immediately having the valves open. When the cylinder reactivates, solenoids inside send an oil pressure signal directly to the control ports on the lifters, and the mechanism controlling the latching governs the valves closing and opening at the right place.

What all this means for the driver is that the engine has the ability to operate more often, while at the same time putting a fewer number of cylinders to use. This ultimately saves fuel, and gives the driver a feeling of power on demand that comes from Chevy's Gen V Small Block V-8 engines. The 6.2-liter engine with this Dynamic Fuel Management system is the absolute most powerful gas V-8 in the segment, and is SEA-certified at 420 horsepower, while paired appropriately with a Hydra-Matic 10-speed automatic transmission. Both of these transmissions have enhancements that were carefully designed to improve the quality of every single gearshift, noticeable during quick urban drives, or while out kicking dirt up on trails.

There is also a centrifugal pendulum absorber torque converter on board, used to reduce vibrations, specifically when cylinders are in the process of deactivating. These engines also feature a revolutionary start/stop technology that helps save valuable fuel during stop-and-go traffic, and they both will be constructed at the GM Tonawanda Engine Plant in Buffalo, New York. The 2019 Silverado is slated to go on sale this fall, when many excited customers will be able to see just how groundbreaking and able to conquer the wild it truly is. We've always been crazy about trucks here at the Powerhouse, and there's no better time than summer to scope out the capabilities of the incoming fleet!
