Claim:
1. A linear combustion engine comprising: three cylinders, a first cylinder is a combustion cylinder having a wall, a head attached at the combustion cylinder first end and a distal end of the combustion cylinder being is attached to a body, with a combustion chamber beneath the head, where; a second cylinder is an air cylinder that is a main shaft with one end located interiorly to the combustion cylinder and a distal end of the main shaft located interiorly of a third cylinder, having a wall and both ends defined by attached opposing pistons and is further defined as a rack, the third cylinder is a oil cylinder having a wall and is open at the oil cylinder top end and closed at the oil cylinder distal end by a base of the engine, where the oil cylinder is defined as one unit with the base of the engine; and having three acting pistons, where a first piston is a combustion piston that has at least one provision in the combustion piston head is an air jacket that is a through opening to the air cylinder, and is located in the combustion cylinder beneath the head having the combustion chamber above the combustion piston; and a second piston is a stationary piston that extends from the base of the engine through the center of the oil cylinder where the stationary piston is also one unit with the base, and the stationary piston head is located within the air cylinder and is defined by having a through air hole with one opening in the stationary piston head and an other opening where the stationary piston is one with the base open to outside air; and a third piston is an oiling piston that is attached to the distal end of the main shaft and is located within the oil cylinder and is opposing the combustion piston, where the oiling piston has two provisions in the oiling piston head, further defined as oil outlets; and having at least one spring that is used as an energy storing device where the energy created by combustion is stored on the spring and the spring is held until energy is required; and having a controlled exhaust valve that does not open immediately after combustion but opens only as the spring is released to preform work.
