Abstract
Abstract An induction system and control method for an internal combustion engine that will improve running under low speed, low load conditions by increasing turbulence in the combustion chamber through the use of a control valve positioned in the induction system for the engine. Under high speed, high load conditions, the control valve is held in an open position and thus, the engine is capable of obtaining high output since there is no restriction to the intake air flow. In addition, transient conditions of the engine, such as variations in idle speed, variations in the amount of EGR, changes in speed, such as acceleration or deceleration, starting and warmup, are compensated for by positioning the throttle control valve to obtain optimum performance, and in some instances, the amount of fuel supplied to the engine is also varied so as to improve exhaust emission control and reduce fuel consumption.
