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 calculate quantity of air filled into a cylinder irrespective of an operation condition of an engine. SOLUTION: Quantity of air filled into the cylinder at steady time being quantity of air filled into the cylinder when assuming that a current operation condition of the engine is a steady condition is calculated using a primary function expression of intake pipe pressure IM when closing an intake valve. Coefficient of compensation decided in accordance with difference between amount of remaining gas when assuming that the current operation condition of the engine is the steady condition and amount of remaining gas in the current operation condition of the engine is calculated. By compensating the quantity of air filled into the cylinder at the steady time by the coefficient of compensation, the quantity of air filled into the cylinder in the current operation condition of the engine is calculated. Amount of fuel injection is calculated based on the quantity of air filled into the cylinder. COPYRIGHT: (C)2007,JPO&INPIT
