Abstract
A multi-cylinder reciprocating piston internal combustion engine is divided into a working section and a compressor section, with the working section supporting the combustion function and the compressor dedicated solely to infusion of intake charge into the working section. In a preferred embodiment, the compressor employs a conjugate drive motion translator with cycle dynamics matched to optimize compressor function. This is characterized by a displacement of crankshaft orientation from 0 degrees at top piston position. The working portion employs a conjugate drive motion converter exhibiting cycle dynamics matched to either a two, four, or diesel engine power cycle.
Claims36
A reciprocating piston internal combustion engine having a plurality of cylinders for slideably receiving a corresponding plurality of mated pistons therein moving in synchronous reciprocation relative to the rotation of a crankshaft, comprising:
- (a) a shuttle having a slot therein affixed to a first of said plurality of pistons, one side of said slot being defined by a first trackable profile having a first circumferential length and an opposite side being defined by a second trackable profile having a second circumferential length, said slot receiving a crankpin of said crankshaft for interconverting between reciprocating motion of said first piston and rotary motion of said crankshaft, said interconverting characterized by an angular displacement of said crankshaft to an orientation other than 0 degrees at top piston position;
- (b) a pair of conjugate drivers rotatably mounted on said crankpin, one of said conjugate drivers having a first tracking profile with a third circumferential length, which is equal to said first circumferential length and the other of said conjugate drivers having a second tracking profile with a fourth circumferential length, which is equal to said second circumferential length;
- and
- (c) means for interconverting between reciprocating motion of the remainder of said plurality of pistons and rotary motion of said crankshaft, at least one of said plurality of cylinders dedicated to infusing an intake charge into at least one other of said plurality of cylinders, the at least one other of said plurality of cylinders capable of serving as a combustion chamber.
