Abstract
Official abstract text for this publication.
A control device for an internal combustion engine is mounted on a vehicle, and includes an engine, a catalyst and a control unit. The engine is a bifuel engine using gas fuel and liquid fuel as its fuel source. The control unit makes an air fuel ratio rich and increases a proportion of the gas fuel if a temperature of the catalyst is higher than a predetermined upper limit value at a time when the liquid fuel is used.
First claim
Opening claim text (preview).
The invention claimed is: 1. A control device for an internal combustion engine which is configured to use gas fuel and liquid fuel as a fuel source, the gas fuel and the liquid fuel provided to the internal combustion engine via a gas fuel injection valve and a liquid fuel injection valve, comprising: a catalyst which cleans up exhaust gas of the internal combustion engine; and an electronic control unit programmed to control the gas fuel injection valve and the liquid fuel inj…
