  "textContent": "An internal combustion engine (1) includes an intake variable lift amount mechanism (14i) that changes a maximum lift amount and valve-open period of an intake valve (9), and an exhaust variable lift amount mechanism (14e) that changes a maximum lift amount and valve-open period of an exhaust valve (10). A control unit (26) executes a process to increase the valve-open period of the intake valve (9) and reduce the valve-open period of the exhaust valve (10), when idling with a temperature of the internal combustion engine (1) that is equal to or higher than a reference value.",
