CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE

Title:

CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE

Document Type and Number:

WIPO Patent Application WO/2005/019630

Kind Code:

A1

Abstract:

A control device of an internal combustion engine, wherein a throttle valve passing air flow calculation expression for indicating a throttle valve passing air flow (mt) as the function of a downstream side intake tube inner pressure on the downstream side of a throttle valve and a cylinder intake air flow calculation expression for indicating a cylinder intake air flow (mc) as the function of the downstream side intake tube inner pressure calculates the downstream side intake tube inner pressure (Pm) and the cylinder intake air flow (mc) when the throttle valve passing air flow (mt) obtained by using the throttle valve passing air flow calculation expression agrees with the cylinder intake air flow (mc) obtained by using the cylinder intake air flow calculation expression as a downstream side intake tube inner pressure (Pmta) and a cylinder intake air flow (mcta) when the engine is stationarily operated under the operating conditions when the air flow (mt) agrees with the air flow (mc).
