CONTROLLER OF INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a controller of an internal combustion engine capable of estimating atmospheric pressure in various operation states.SOLUTION: A compressor 24a of a turbocharger 24, when an intake air amount passing through an air cleaner 22 is equal to or less than a threshold Qaccording to an engine rotational speed Ne, in order to supercharge air, feeds compressed air to an engine 30 to enhance heat efficiency of the engine 30. A throttle valve 28 is arranged in an intake pipe 21, and controls an intake air amount Q. An atmospheric pressure is estimated based on a pressure P in an intake passage positioned between the compressor and the throttle valve.SELECTED DRAWING: Figure 3
