Abstract:
1. An engine, comprising: an engine block having a hole formed therein; a piston carried within said engine block and dimensioned for reciprocal motion within said hole of said engine block, said piston having a piston head and a rod extending therefrom, said rod having a first end attached to said piston head and an opposing second end; a rocker arm having a fulcrum defining a first portion and an opposing second portion, said first and said second portions being pivotable about said fulcrum, said rocker arm having a pivot hole formed at said fulcrum, said first portion having a first end, said second portion having a second end, said first end of said first portion having a hole formed therein; a pivot pin carried in said pivot hole in said rocker arm and attached to said engine block so that said rocker arm can pivot with respect to said engine block about said pivot pin; an eccentric dimensioned to fit in said hole of said first end of said first portion of said rocker arm, said eccentric rotating about an axis, said second end of said piston rod being attached to said eccentric at a location spaced apart from said axis of said eccentric so that, as said piston rod reciprocates, said second end of said piston rod rotates about said axis of said eccentric and causes said rocker arm to pivot about said pivot pin; a connecting link having a first end and an opposing second end, said first end being connected to said second portion of said rocker arm, said connecting link reciprocating when said rocker arm pivots about said pivot pin in response to reciprocal motion of said piston rod; and a crankshaft having a counterweight and a crank arm, said crank arm being attached to said second end of said connecting link so that when said connecting link reciprocates, said connecting link rotates said crankshaft.
