Abstract

PURPOSE: To reduce emission of NOx without deteriorating fuel economy, by providing an exhaust gas recycling passage interconnecting an exhaust gas passage to a combustion chamber and also providing this exhaust gas recycling passage with an exhaust gas recycling valve (EGR valve).
CONSTITUTION: Valve timing of an intake valve 11 is variably controlled by a 3-dimensional cam 13, which is to shift in the axial direction of a cam shaft, through hydraulic cylinder, etc. depending on load. The 3 dimensional cam 13 is designed capable of controlling valve timing of an EGR valve varialy. This EGR valve 14 is installed between a combustion chamber 15 and an exhaust gas recycling passage 16 so that timing and volume of the exhaust gas returning flow are controlled. An EGR passage 16 has such a function as to allow a part of the exhaust gas to return directly to the combustion chamber 15 by utilizing pressure difference between negative pressure Fa in the cylinder, which generates in the cource of air-intaking stroke after closing of an intake valve 11, and exhausting pressure Fb.
