Next Generation Technology State-of-the-Art technologies: Direct injection technology: • Moves the point where fuel feeds into an engine closer to the point where it ignites, enabling greater combustion efficiency. • Fosters a more complete burn of the fuel in the air-fuel mixture. • Operates at a lower temperature than conventional port injection. • Allows the mixture to be leaner, so less fuel is required to produce the equivalent horsepower of a conventional, port injection fuel system Active Fuel Management (AFM) Technology • Expands the range of operation by more than 10 percent. • AFM temporarily deactivates four of the cylinders on the V-8 engines under light load conditions – effectively operating as a V-4 • When cylinders are deactivated, the engine’s pumping work is reduced, which translates into real-world fuel economy improvements • Seamlessly reactivates all cylinders when full power is demanded. Variable Valve Timing (VVT): • The dual-equal cam phasing system adjusts camshaft timing at the same rate for both intake and exhaust valves • Allows linear delivery of torque, with near-peak levels over a broad rpm range, and high specific output without sacrificing overall engine response. Variable Displacement Pump: • Advanced Oiling System GM engineers spent over 10 million hours creating the Next Gen technology. Every millimeter of the combustion system was carefully designed to support the most ideal combination of direct injection, active fuel management and variable valve timing, making the most of power, torque and efficiency. Additional Features: All new weight saving aluminum cylinder block casting All new cylinder head design with new port shape and valve placement Increased compression ratios Advanced oiling system - variable displacement pump High-strength aluminum alloy pistons Oil-jet piston cooling Stronger, larger diameter push rods High flow intake manifold and electronic throttle Iridium tipped, extended life, spark plugs 58x crank timing 6.2L V-8 AFM VVT DI (L86)
