Monoblock internal combustion engine with air compressor components

A monoblock engine and gas compressor combination comprising:

• an internal combustion engine having;
• a plurality of cylinders;
• a rotating crankshaft;
• and
• a plurality of connecting rods engaged to said crankshaft, one each reciprocatingly disposed within a corresponding one of said plurality of cylinders,
• wherein at least one of said plurality of cylinders is a power cylinder having a power piston connected to one of said plurality of connecting rods and reciprocatingly disposed within said power cylinder;
• a gas compressor having;
• a number of compressor cylinders, each disposed in communication with a corresponding one of said plurality of engine cylinders other than said at least one power cylinder;
• a number of compressor piston assemblies each reciprocatingly disposed within a corresponding one of said number of compressor cylinders;
• and
• manifold means for introducing a gas into said number of compressor cylinders and for maintaining the gas pressure within said compressor cylinders at above atmospheric pressure;
• means for connecting each of said number of compressor piston assemblies to a corresponding one of said plurality of connecting rods, said means including a piston pin rotatably disposed between said connecting rod and said compressor piston;
• wherein said power piston has a first weight and and each of said number of compressor piston assemblies has a second weight greater than said first weight;
• and
• further wherein said second weight of each of said compressor piston assemblies includes a piston having a piston area A, and its minimum weight exceeds P*A and is determined from the following equation-
• W=(2.84*10.sup.-5 *n.sup.2 *r(COS(r)+(r/L)*COS(2r)))
• where P is the gas pressure into said corresponding one of said number of compressor cylinders, n is the rotational speed of said crankshaft at the gas pressure P (in rpm), r is the radius of a crankarm of said crankshaft, L is the length of said connecting rod, and r is an angle of said crankshaft relative to the top dead center position of said connecting rod.
