Title: HIGH-EFFICIENCY VCR ENGINE with VARIABLE VALVE ACTUATION AND NEW SUPERCHARGING TECHNOLOGY

Abstract

Higher efficiency engines are needed for full size pickup trucks, utility vans and medium duty trucks. The primary objective of the program was to demonstrate the potential for improving the fuel economy of a full-size pickup truck by 40 percent while producing at least 281 horsepower. Commercialization requirements include: 1. High torque values at low vehicle speeds: This capability is needed for accelerating a heavy vehicle from a standstill, accelerating uphill, towing or any combination of these factors. 2. High power output: This capability is needed for accelerating onto a highway or passing at higher speeds. The vehicle may be carrying a heavy load, going uphill and/or towing. 3. Compliance with tailpipe emission regulations: This requirement must be met, and is difficult or costly to attain with diesel engine technology. 4. Low fuel consumption: This capability is needed both for reducing operating costs and to reduce greenhouse gas (GHG) vehicle emissions. The capability is also essential for complying with fuel economy standards. 5. Affordability: The powertrain cost must be consistent with mass market pricing. 6. Engine size and weight: The engine must fit in the existing engine bays. Engine weight must also be minimized. 7. Favorable noise vibration and harshnessmore » (NVH): The VCR must not present unique NVH challenges. The current program was successful. The efficiency target was achieved and the engine produced 300 horsepower.« less
