Can The 2019 Silverado Lead the Industry with Dynamic Fuel Management?

Your Vehicle Seldom Needs all Eight Cylinders

The 2019 Silverado implements a fascinating concept. If you enjoy the thought of owning an eight-cylinder vehicle you know you have a lot of power available if you need it. A diesel engine, a V-8 and a 10-speed automatic transmission conspire to make the 2019 Chevrolet Silverado the industry leader in dynamic fuel management and efficiency.

Unless you are hauling a lot of weight in your truck and pull a loaded trailer behind it – all while slogging up a long mountain pass, your truck seldom needs eight cylinders for effective and efficient power. Most likely, much of your driving time tends toward steady highway miles or start and stop traffic. No matter if you regularly experience all three scenarios, DFM has the technology to handle your truck efficiently in a manner that saves fuel. This means adding hefty savings to your overworked pocketbook. Here at our dealership, we know you work hard for that money and we intend to help you save as much of it as we can.

What Does DFM Do?

DFM permits powering only the cylinders required for performance delivery you find necessary at any given time. 17 different cylinder operating patterns efficiently control fuel consumption while providing all the power you expect. When you are navigating rush hour traffic DFM features your choice of selections to start or stop your cylinder patterns. Highway driving at a steady pace may use only one or two cylinders, allowing shutdown on the other cylinders to save fuel and increase efficiency as much as 21 percent.

How Does DFM Work?

An internal computer calculates cylinder need by monitoring the accelerator and anticipates your torque as required up to 80 times per second. An eight-cylinder engine contains 16 hydraulic valve lifters. Electronically powered mechanics control valve actuation by sending signals that continually stops or starts each valve lifter. Using solenoids, oil pressure delivery rates control each lifters port, which turns the lifter latching devices on or off. When a cylinder powers off the two-piece lifter collapses, thus preventing the valve from reopening. Sending an oil pressure signal to the port lifters tells the latching system to reopen the valve and restore normal function.

Form Meets Function

DFM technology has been around for several years. A common complaint, however, kept it from widespread use. Every time a cylinder activated, deactivated or reactivated a rough transition transpired sending harsh vibrations throughout the system to the driver. Using the dynamic system to control cylinder firing allows an algorithm a way to distribute heat evenly while determining cylinder loading events. Targeting a specific cylinder firing density uses sustained engine load to determine and calculate the right load. This spreads the cylinders firing over the whole system and decreases noticeable transition vibrations.

Are There Additional Efficiency Measures?

Although the 2019 Silverado is larger than previous models, it weighs 450 pounds less than ever. Less vehicle weight means it needs less fuel to operate efficiently. Aerodynamic improvements such as front grille air breaks and shutters, side panel displacement and a rear edge spoiler built into the cab work together to decrease truck bed wind drag by seven percent. By increasing lift and decreasing drag, the Silverado is less wind resistant. When you have increased wind drag your truck eats more fuel. Better aerodynamic designs incorporated to reduce the Silverado's bulk also serve to cool your engine. This contributes to lower fuel consumption and increase your vehicle's overall efficiency while in operation.
