Claim Text:
1. A PD-ICE, comprising: a. a housing structure having a flow suction port, a flow discharge port, and a cavity; b. a positive displacement driving piston reciprocally mounted inside said housing cavity and driven through a reciprocating motion within said housing cavity by combustion of fuel; and c. a shunt pulsation trap apparatus comprising a trap chamber positioned adjacent to said housing cavity, at least one pulsation dampening device positioned within said trap chamber, at least one trap inlet branching off from said cavity before said discharge port and into said pulsation trap chamber upstream of the pulsation dampening device, and at least one trap outlet downstream of the pulsation dampening device and communicating said pulsation trap chamber with said discharge port; and d. wherein in operation said PD-ICE achieves reduced pulsation and NVH, reduced exhaust size and weight, and improved fuel efficiency.
