초록
A 2.0 Liter High Performance Engine(HPE) is developed for next generation Hyundai sporty coupe. It is based on newly developed Hyundai Theta Engine under mass production, which is equipped with aluminum alloy cylinder block, ladder frame, and intake Continuously Variable Valve Timing(CVVT). The modifications to HPE include the reinforcement of moving parts for high revolution over 7,500rpm, adoption of 2-stage Variable Valve Lift(VVL), Variable Intake System(VIS), and exhaust Continuously Variable Valve Timing(CVVT) for improvement in fuel efficiency as well as in performance. By applying these variable mechanisms, it was possible to achieve significantly improved torque, power and fuel consumption: 40% improvement in maximum power, 10% improvement in maximum torque, and 4% reduction in fuel consumption. Investigation shows that the application of VIS and VVL can give major improvements to performance and fuel consumption respectively.
