Head and Valvetrain Specs K20A6
The Honda K20A6 engine features a DOHC (Double Overhead Camshaft) head design and VTEC (Variable Valve Timing and Lift Electronic Control) valvetrain technology.
The DOHC head design features two camshafts that operate the engine’s valves, providing improved airflow into the combustion chambers and improving engine performance and efficiency.
The VTEC valvetrain technology is a system that varies the valve lift and duration based on engine RPM, providing improved engine performance and efficiency.
This technology allows the engine to switch between two different cam profiles, one for low RPM operation and one for high RPM operation.
At low RPM, the engine uses a milder cam profile for improved fuel efficiency, and at high RPM, the engine switches to a more aggressive cam profile for improved performance.
The combination of the DOHC head design and VTEC valvetrain technology makes the Honda K20A6 engine a highly capable and efficient engine.
