Patent Searching and Data


Title:
HALF CYCLE ECCENTRIC CRANK-SHAFTED ENGINE
Document Type and Number:
WIPO Patent Application WO/2010/151415
Kind Code:
A3
Abstract:
An internal combustion engine 100 having a piston 104 reciprocating in a cylinder 102 between TDC and BDC positions to influence a drive shaft 110. The drive shaft 110 is associated with an expandable piston rod extension 140 which in turn attaches to a piston rod 116 to connect the piston 104 with the drive shaft 110. The piston rod extension's 140 length may increase and decrease in accordance with the angular position of the drive shaft 110. The increasing and decreasing length is governed by a guide pin 146 which travels within a channel 148 formed by a portion of the engine block 100a, 100b. Increasing the length of the piston rod extension 140 during the power phase of the engine 100 increases the available torque of the engine 100 without any alteration of the displacement. The assembly may also include a counterweight 126, which itself may travel along an eccentric path generally equal and opposite to the eccentric path along which the piston rod extension guide 146 travels.
