Abstract:
1. An engine comprising: at least two high pressure pistons movable within respective high pressure cylinders and at least one low pressure piston movable within a low pressure cylinder; a first linkage mechanism coupling the low pressure piston to a crankshaft includes a first toggle link, and a second linkage mechanism coupling at least one of the high pressure pistons to the crankshaft includes a second toggle link; wherein the first toggle link is adapted to move from a straight position in a first direction towards the crankshaft to a first knuckled position and then to move through the straight position in a second direction opposite the first direction to a second knuckled position and back to the straight position for every one revolution of the crankshaft, the straight position of the first toggle link corresponds to a top dead centre position of the low pressure piston within the low pressure cylinder; wherein the second toggle link is adapted to move from a straight position to a knuckled position and back to the straight position for every one revolution of the crankshaft, the straight position of the second toggle link corresponds to a top dead centre position of the high pressure piston within the high pressure cylinder; and wherein the low pressure piston moves through twice the number of strokes moved through by each of the high pressure pistons in the same period of time.
