Title: Air quantity detecting device for internal combustion engine
Inventor: TAKAHATA TOSHIO
IPC: G01F9/00
Filed: 1986-07-24
Abstract: PURPOSE:To enhance transient responsiveness by correcting the air flow rate at a steady state, which has been calculated by the opening of a throttle valve and the engine speed, by means of a delay factor corresponding to the operating condition, and adding a prescribed adding value to the air flow rate to a cylin der to detect the passing air quantity at a fuel injection part. CONSTITUTION:From a throttle valve opening alpha and an engine speed N, an air flow rate QH is accurately detected without being influenced by an intake pulsation. In addition, by adding a correction to this air flow rate QH by means of a delay factor K based on the throttle valve opening alpha and the engine speed N, the air flow rate Qc to a cylinder is accurately detected without worsening responsiveness even in the course of transient. And by adding a prescribed adding quantity  CM (corresponding to the air flow rate Qc and the volume of the intake manifold) to the air flow rate QH, the passing air quantity at a fuel injection part can be accurately detected.
