A / ACTIVE FUEL MANAGEMENT

By sensing load and demand, Active Fuel

Management improves efficiency by activating

or deactivating cylinders (two on the V6 and four

on the V8). Under demanding conditions, like high

speeds or when loads require more power, the

valve’s switching mechanism is depressurized,

re-engaging the cylinder and restoring full

power—without you ever noticing the transition.

B / DIRECT INJECTION (DI)

For precise fuel distribution and fast, efficient

combustion, all engines benefit from DI

technology. The system injects the fuel directly

into the combustion chamber. By injecting fuel

at over 13,790 kPa (2000 psi), the air and fuel

mix more completely.

C / VARIABLE VALVE TIMING (VVT)

For responsiveness in low-speed city driving

and bold power for open-road passing or

trailering, all Silverado engines feature

continuously Variable Valve Timing (VVT). It

monitors and adjusts valve open and close

points for near-peak levels of torque across the

entire range of engine speeds.
