CONSTRUCTION
Each cylinder has 2 intake valves and 2 exhaust valves. Intake and exhaust efficiency is increased due to larger total port areas.
The valves are directly opened and closed by 2 camshafts.
The VVT-i system is used to achieve low fuel consumption, high engine performance and reduced exhaust emissions.
