Internal combustion engine system, power output apparatus, vehicle, and method for controlling the internal combustion engine system
First Claim
1. An internal combustion engine system having an opening and closing timing changing module capable of changing opening and closing timing of an intake valve of an internal combustion engine, said internal combustion engine system comprising:
- a fuel injection module capable of injecting a fuel to each cylinder of said internal combustion engine;
an advance angle instruction module which performs an advance angle instruction for advancing opening and closing timing of said intake valve when predetermined high torque demand is made based on an operation of an operator;
an opening and closing timing control module which controls said opening and closing timing changing module so that said intake valve is opened and closed in target opening and closing timing based on an operation state of said internal combustion engine and presence or absence of an advance angle instruction by said advance angle instruction module;
a target fuel injection quantity setting module which sets a target fuel injection quantity based on target power to be output from said internal combustion engine and presence or absence of the advance angle instruction by said advance angle instruction module; and
a fuel injection control module which controls said fuel injection module so that fuel injection is performed based on said set target fuel injection quantity.

Abstract
When a catalyst temperature θc is higher than a threshold value θref (S320), an increase coefficient Kf is set so as to tend to be larger as opening and closing timing of an intake valve is advanced, an intake air flow Qa is larger, and a rotation speed Ne of the engine 22 becomes higher (S340), a target fuel injection quantity Qf* is set based on a product of a basic fuel injection quantity Qftmp set based on the intake air flow Qa and an increase coefficient Kf (S350), and fuel injection of the set target fuel injection quantity Qf* is performed (S360).
