Abstract: A low-pressure loop EGR device for an engine with a supercharger, EGR passage, and EGR valve. An ECU controls the EGR valve to fully close, the intake valve to fully open, and the throttle valve to open at a sonic opening degree during deceleration and fuel cut-off. The ECU obtains an actual opening degree of the throttle valve based on the detected intake amount and a predetermined reference formula of valve passing flow rate. The ECU performs correction control of the throttle valve based on a throttle opening degree correction value learned from a difference of the actual opening degree and the predetermined opening degree. The ECU obtains an actual opening degree of the intake valve similarly to the above, and performs correction control of the intake valve based on an intake opening degree correction value learned by the difference between the actual opening degree and the predetermined opening degree.

Abstract: It is a challenge to reduce unburned hydrocarbon emissions for gaseous fuelled engines, especially at low engine load conditions, to meet demanding emission regulation targets. A method for reducing unburned hydrocarbon emissions in a lean-burn internal combustion engine that is fuelled with a gaseous fuel comprises adjusting the timing for closing of an intake valve as a function of engine operating conditions by one of advancing timing for closing of the intake valve and closing the intake valve earlier during an intake stroke; and retarding timing for closing of the intake valve and closing the intake valve later during a compression stroke. The volumetric efficiency of the internal combustion engine is reduced and unburned hydrocarbon emissions are maintained below a predetermined level.
