Optimized high pressure internal combustion engines

摘要

An improved high pressure, high r.p.m. engine having a single cylinder with opposed pistons reciprocating in the cylinder and each piston being connected to dual connecting rods that are connected to counterrotating crankshafts, the cylinder having a central collar between the heads of the opposed pistons that form a specially configured combustion chamber for high turbulence mixture of air and fuel injected from a plurality of fuel injectors peripherally arranged around the cylinder, the pistons being operated with a cycle phase shift to prolong the period of peak compression and provide a double squish action for improved fuel air mixture, the air being supplied under high compression from a counterrotating turboblower assembly that is in part driven by the engine drive train and in part driven by the expansion gases of the combustion process, the engine being provided with specially designed high pressure pistons that have an axially symmetrical piston head and a spherical bearing mount to a wrist pin assembly having dual rolling wrist pins for eliminating side thrust of the piston head and maximizing the projected surface area for transmission of piston thrust forces from a piston head to the connecting rods and crankshafts.
