Abstract

595493 Disclosed is an internal combustion engine to increase the dwell period of the piston at TDC to improve the efficiency and operating characteristics of the engine. The engine comprises a piston configured to move within a piston cylinder throughout a stroke cycle and a rotatable crankshaft comprising a crankshaft cam surface. A connecting rod assembly comprises a piston connecting rod pivotally connected at one end to the piston and a crankshaft timing rod pivotally connected at one end to the piston connecting rod at a conrod joint and at another end to the crankshaft. A rocker arm is configured to contact the profile of the crankshaft cam surface during its rotation cycle at one end and is pivotally connected to the rocker arm connecting rod, which is in turn pivotally connected to the conrod joint. The rocker arm and rocker arm connecting rod are together configured to move the conrod joint as the rocker arm is moved on the crankshaft cam surface to form a working crank angle between the piston connecting rod and the crankshaft timing rod when the piston is at its top dead centre (TDC) position. At its position of maximum displacement within the piston cylinder during a piston stroke cycle, the travel of the piston is slowed through the TDC position and the position of maximum displacement during the piston stroke for a predetermined angle of rotation of the crankshaft.
