Abstract
Official abstract text for this publication.
In a control system that includes a pressure accumulating portion that supplies CNG to a fuel injection valve and a regulator that adjusts a pressure in the pressure accumulating portion to a set pressure and of which a valve element opens when CNG is supplied to the pressure accumulating portion and closes when supply of CNG to the pressure accumulating portion is shut off, a control parameter relating to a combustion state in an internal combustion engine is controlled on the basis of a length of a period during which an opening degree of the valve element reduces from a first predetermined opening degree to a second predetermined opening degree when the pressure in the pressure accumulating portion is adjusted to the set pressure by the regulator.
First claim
Opening claim text (preview).
The invention claimed is: 1. A control system for an internal combustion engine that uses compressed natural gas as fuel, comprising: a pressure accumulating portion that stores compressed natural gas, which is injected from a fuel injection valve of the internal combustion engine, in a state where the compressed natural gas is kept at a set pressure, and that supplies compressed natural gas to the fuel injection valve; a regulator including a valve element that opens when the c…
