Compressed air powered motor vehicle

A compressed air powered motor vehicle, comprising:

• an engine including an intake and an exhaust pipe, said engine being configured for operating on compressed air received in said intake and expelling exhaust air through said exhaust pipe;
• a compressed air storage container in fluid communication with said intake of said engine;
• at least one compression mechanism configured for compressing the exhaust air, each said compression mechanism including:
• a substantially hollow cylinder having at least two inlets in fluid communication with said exhaust pipe of said engine, each said inlet including a first check valve allowing passage of the exhaust air into said cylinder while preventing passage of the exhaust air out of said cylinder, said cylinder also having at least two outlets in fluid communication with said compressed air storage container, each said outlet including a second check valve allowing passage of the compressed air out of said cylinder while preventing passage of the compressed air into said cylinder;
• a piston slidably disposed within said cylinder, said piston forming a substantially airtight seal with said cylinder, said piston having a first side and a second side, said cylinder and said first side of said piston defining a first chamber, said cylinder and said second side of said piston defining a second chamber, each said chamber being associated with at least one said inlet and at least one said outlet;
• and
• a rod extending axially from said cylinder, said rod having a first end attached to said first side of said piston and a second end disposed outside said cylinder, said rod being slidable relative to said cylinder;
• a rocker arm having a first end, a second end and a pivot point disposed between said first end and said second end, said first end of said rocker arm being attached to said second end of said rod of a first said compression mechanism, said rocker arm being configured for pivotal oscillation about said pivot point, thereby reciprocating said rod and said piston within said cylinder;
• and
• a cam coupled with one of said first end and said second end of said rocker arm, said cam being configured for pivotal oscillation of said rocker arm.
