The new V6 3.5L gasoline direct injection engine, VQ35DD, was developed for the midsize premium SUV segment. This engine is the newest descendant of the VQ engine family and incorporates the latest technologies focused on enhanced driving performance, combined with high-level of environmental performance. Additional improvements include torque and power increase as well as improved fuel economy and emission performance. Simultaneous realization of both throttle response and smoothness are also in focus. To achieve these features, direct injection system, high response motor-driven intake Continuously Variable Valve Timing Control (e-Motor VVT), individual spark timing, mirror bore spray coating on the cylinder block, and various friction reduction technologies, such as variable displacement oil pump, are applied. Maximum engine power and torque are increased by 8 to 10%. Minimum BSFC is improved by 6%, combined with a wider spread of lower BSFC range considering CVT applications.
This paper provides an overview of the engine and details the new technologies as well as the resulting achievements in the target performance.
