ABSTRACT:
A number of embodiments of induction systems for internal combustion engines that permit operation on the Miller cycle without introducing pumping losses or by substantially minimizing the pumping losses. Basically, the system provides a variable volume air chamber that supplies the major portion of the intake charge or all of the intake charge under low-speed, low-load conditions. Various valving and variable volume chamber constructions are illustrated. In addition, embodiments using air-assisted fuel injection are also disclosed.
