Engine control device

A control device for an engine, the engine comprising:

• a combustion chamber;
• a first intake opening and a second intake opening each communicated with the combustion chamber;
• a first intake valve and a second intake valve provided, respectively, to the first intake opening and the second intake opening;
• and an intake port connected to the first intake opening and the second opening, the control device comprising:
• a first valve operating mechanism configured to control a valve opening timing and a valve closing timing of the first intake valve;
• and
• a second valve operating mechanism configured to control a valve opening timing and a valve closing timing of the second intake valve, independently from the first intake valve,
• wherein the second valve operating mechanism is operable, in an intake stroke of the engine, to close the second intake valve after an elapse of a given delay time since the first intake valve is closed by the first valve operating mechanism, and
• wherein the delay time is a time period during which a pressure wave generated upon closing of the first intake valve reaches the second intake valve through the intake port.
