摘要： PROBLEM TO BE SOLVED: To accurately provide cylinder intake fresh air amount by accurately providing intake valve passing gas flow amount when burned gas blown back to an intake passage in the overlapping of valves is sucked again into a cylinder. SOLUTION: An electric control device 80 calculates the flow of the intake valve passing gas sucked into the cylinder 21 through an intake valve 32 based on an equation expressing the flow of fluid passed through a restriction part. When the electric control device determines that the cumulative value Mi of the intake valve passing gas flow is larger than O and the gas sucked into the cylinder is fresh air, it calculates the intake valve passing gas flow by using the temperature of the fresh air. When the electric control device determines that the cumulative value Mi is smaller than O and the gas sucked into the cylinder is the burned gas blown back to the intake passage, it calculates the intake valve passing gas flow by using the temperature of exhaust gas. The electric control device estimates the cylinder intake fresh air amount by integrating the intake valve passing gas flow amount thus obtained. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide an intake air volume estimating device of an internal combustion engine for improving the calculation accuracy of the cylinder filling intake air volume by accurately calculating a spitting flow rate to an intake port from a cylinder by taking into consideration the pressure of the intake port.
SOLUTION: When estimating an intake air flow rate mc filled in the cylinder by using a throttle valve model M10, an intake pipe model M20, an intake valve model M30, a cylinder model M40, and a vent valve model M50 of modeling respective elements of an internal combustion engine intake system, when causing the spitting of making burnt gas in the cylinder flow backward to the intake port when opening/closing the intake valve, intake port pressure is calculated separately from intake pipe pressure by using an intake port model M25. Thus, since the accurate spitting gas volume is calculated by adding the influence of a local pressure increase in the intake port caused by spitting, the estimation accuracy of the cylinder filling intake air volume is improved.

摘要： PROBLEM TO BE SOLVED: To accurately estimate a heat flow rate transmitted to air in a cylinder from the cylinder by accurately estimating an air flow speed in the cylinder.
SOLUTION: An electric control device 80 estimates a speed (an intake valve passing flow speed) uc at the periphery of an intake valve of the air sucked in the cylinder 21 by passing through the intake valve 32, and estimates a cylinder air flow speed (u) being an average speed of the air in the cylinder on the basis of an equation of motion Mct×(du/dt)=mc×uc-fp always satisfied with respect to the air in the cylinder. Here, Mct is the mass of the air in the cylinder, (u) is the cylinder air flow speed, mc is a flow rate of the air sucked in the cylinder by passing through the periphery of the intake valve, uc is the intake valve passing flow speed, and fp is a force for damping a flow speed of the air by the viscosity of the air in the cylinder. The electric control device estimates a transmission rate and a heat flow rate of heat transmitted to the air in the cylinder from the cylinder on the basis of the cylinder air flow speed (u).
