Abstract
The invention relates to a piston internal combustion engine, which finds an application in transportation technology. The engine has pistons with two opposing heads (1), which move in two pairs of cylinders (2, 3). Each pair of cylinders (2, 3) are opposite to one axis. To the cylinders (2) are mounted exhaust valves (5), and to the cylinders (3) are provided intake valves (4). In the cylinders (2), the operating strokes and discharge are performed, and in the other cylinders (3), takes place the intake and compression of the main part of the intake volume to combustion chambers (6), from which the gases enter the cylinders (2) for operating strokes and discharge.
Hybrid split-cycle air engine, comprising: a crankshaft rotatable about a crankshaft, a compression piston slidably received within a compression cylinder and operatively connected to the crankshaft, intake valve, expansion piston, crossover passage, air tank and method.
