One of the vehicles that customers are so excited about here at West Chevy of Knoxville is the all-new for 2019 Silverado 1500: as rugged, awesome, and high-performing as it is, there is another great quality that will draw many to it. This truck will offer the most advanced gasoline V-8 Engine in the brand's history, as updated versions of the 5.3-liter and 6.2-liter V-8s sport this important feature. This revolutionary technology that enables the engines to operate in 17 different cylinder patterns is one of the best ways to optimize efficiency and delivery of power. This system was first introduced in 2005, and the technology has advanced greatly since then.
Small Block chief engineer Jordan Lee commented on the effectiveness of the process: “Dynamic Fuel Management enables only the cylinders needed to deliver the power you want, seamlessly delivering the best balance of power and fuel economy.” Active Fuel Management is another variation which alternates between 8-and 4-cylinder modes, and DFM incorporates the use of 17 very complex cylinder patterns. The greater number of cylinders constantly to optimize the delivery of power, and efficiency at all speeds. Part of the high-tech wonder and upper-level optimization of this system is regarding the electromagnetics: the electromagnetic system deactivates and reactivates all 16 of engine's hydraulic valve lifters, controlling the actuation of valves.
When a cylinder in this system is activated, the two-piece lifters use energy to collapse on themselves, which prevents them from opening the valves. When the cylinder reactivates, solenoids inside send an oil pressure signal directly to the control ports on the lifters, and the latching mechanism allows the valves to close and open at the right pace. What all this means for the lucky driver of the new Silverado is that the engine has the ability to operate more often, using a fewer number of cylinders. This 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 with DFM is the largest and most powerful gas V-8 in the segment, and is SEA-certified at 420 horsepower, while also paired with a Hydra-Matic 10-speed automatic transmission. Both of these transmissions have enhancements specifically designed to improve the quality of every single shift, and a centrifugal pendulum absorber torque converter, that reduces vibrations to improve smoothness, particularly when the cylinders are deactivating. These engines also feature stop/start technology that helps to save valuable fuel during traffic that is stop-and-go. Both engines will be built at General Motors' Tonawanda Engine Plant in Buffalo, New York, and the 2019 Silverado will go on sale this fall. Until then, feel free to come down and see us with any truck questions you have here at West Chevy, and we'll show you all of the features that are part of the Silverado's groundbreaking future!
