内燃機関
Document Type and Number:
Japanese Patent JP5765921
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an internal combustion engine capable of contributing to improvement of various kinds of performance such as output performance, fuel economy performance and exhaust performance by improving combustion with a simple constitution and at low cost to reduce load to a post-treatment system.SOLUTION: This internal combustion engine 1 controls at least one of an excess air ratio, an EGR rate and a residual gas rate so that an oxygen molar fraction of intake air (new air (outside air) and EGR gas, etc.) led to the inside of a combustion chamber 5 is a target oxygen molar fraction. The excess air ratio is controlled by changing intake charging efficiency by controlling valve opening and closing characteristics by a variable valve mechanism (VVA mechanism 200).
