Title:
CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE WITH TURBOSUPERCHARGER
Document Type and Number:
Japanese Patent JP2014152689
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a control device capable of suppressing the worsening of exhaust emission during transient operation of an internal combustion engine with a turbosupercharger.SOLUTION: The control device calculates an actual gas temperature Tb in an intake manifold of the engine from a signal from a temperature sensor 60, calculates an actual supercharging pressure pim of the engine from a signal from a supercharging pressure sensor 54, calculates an actual cylinder intake air amount Gcyl of the engine on the basis of the actual gas temperature Tb and the actual supercharging pressure pim, calculates an actual cylinder supply heat quantity H on the basis of the actual cylinder intake air amount Gcyl and the actual gas temperature Tb, calculates a steady cylinder supply heat quantity Hst as a heat quantity to be supplied into a cylinder during steady operation on the basis of an engine speed and a fuel injection amount, and controls an exhaust amount to be exhausted from the engine to the outside of a system depending on a heat quantity difference ΔH between the steady cylinder supply heat quantity Hst and the actual cylinder supply heat quantity H. Preferably, it sets a target EGR rate or a target supercharging pressure so that the exhaust amount is smaller as the heat quantity difference ΔH is greater.
