8 Theta - II Engine Exhaust Manifold WCC Integrated CCC UCC Before After Exhaust Port Changed Items Integrated CCC (ULEV-II, Euro 4) Improved performance (1~2%) - Reduced resistance and length from cylinder head to catalytic converter Reduced exhaust gas temperature in cylinder head Reduced fuel consumption at high speed. (2~3%) - Increased length of dividing wall and area of heat transfer. Reduced exhaust gas temperature

9 Theta - II Engine Intake Exhaust CMP OCV CVVT Assembly Dual CVVT FunctionDual CVVT ConceptTo use wider operation range of CVVT, dual control is implemented. Control system Read cam edges information from dual (intake / exhaust) CMP sensor Determine valve opening (target / actual) LogicAdjust valve (in/ex) opening timing with PWM control to adjust oil flow through CVVT assembly ComponentDual VVTI modules, Dual CAM sensors, Dual Oil control valves, ECU pins for dual CVVT inputs & controls Improvements To use wider valve overlap range with adjust in/ex opening positions To reduce emission with exhaust valve timing To improve Torque with better optimized valve operation points
