ENGINE UNIT


  1. OUTLINE


    1. A V6 twin-turbo V35A-FTS (3.5 L) engine is used to achieve a higher dimension of balance between fuel efficiency, high performance, clean exhaust gas performance and quietness.

    2. A Direct injection 4-stroke gasoline engine Superior version (D-4S) system (which uses both a direct cylinder injection method and port injection method) is used to perform efficient combustion. In addition, a turbocharger, Electronic Throttle Control System-intelligent (ETCS-i) and Dual Variable Valve Timing-intelligent (Dual VVT-i) system (a continuously variable valve timing mechanism for intake and exhaust) are used to achieve low fuel efficiency, low emissions, high performance and high output.

    3. The Dual Variable Valve Timing-intelligent (Dual VVT-i) system (a continuously variable valve timing mechanism for intake and exhaust) uses a Variable Valve Timing-intelligent by Electric motor (VVT-iE) (a continuously variable valve timing mechanism that operates the electric motor) on the intake side and a Variable Valve Timing-intelligent (VVT-i) (a continuously variable valve timing mechanism that operates oil pressure) on the exhaust side to further expand the degree of freedom of control and achieve optimal valve timings.

    4. A Direct injection 4 stroke gasoline engine Superior version with Turbo (D-4ST) that comprehensively performs supercharging control for the turbocharger and Direct injection 4-stroke gasoline engine Superior version (D-4S) system. By optimizing the shape of the cylinder head port and piston top surface, it is possible to achieve high tumble flow in addition to high-level supercharged pressure control, improving fuel efficiency and low speed torque.

    5. The shape of the high-efficient intake port and combustion chamber is optimized to improve combustion efficiency, and the valve mechanism system is improved to reduce friction loss in each part of the engine. As a result, a high level of engine fuel efficiency is achieved.
