Abrégé

An internal combustion engine, primarily for use in motor vehicles, with improved torque and thermal efficiency. The engine comprises at least one piston configured to move within a piston cylinder throughout a piston stroke; a rotatable crankshaft; and a piston to crankshaft linkage comprising: a piston connecting rod pivotally connected at one end to the piston at a piston pin; and a crankshaft connecting rod pivotally connected at one end to the piston connecting rod at a connecting rod joint and pivotally connected at another end to the crankshaft wherein the internal combustion engine also comprises a control arm configured to direct movement of the connecting rod joint to alter an effective length of the piston to crankshaft linkage as the piston to crankshaft linkage is moved via rotation of the crankshaft to form a working crank angle when the piston is at its top dead centre position for a predetermined angle of rotation of the crankshaft.

Abrégé

An internal combustion engine which produces improved torque and efficiency. The engine comprises a piston; a rotatable crankshaft comprising a crankshaft cam surface; a piston connecting rod pivotally connected to the piston; a crankshaft timing rod pivotally connected to the piston connecting rod at a conrod joint and to the crankshaft; a rocker arm configured to contact the crankshaft cam surface during its rotation cycle and to the conrod joint to move same to form a working crank angle between the piston connecting rod and the crankshaft timing rod; a slipper plate positioned substantially inline between the connecting rod joint and the crankshaft offset pivot point to better manage the angle of connecting rod portions whilst they are rising and falling from the motion of the crankshaft rotation wherein the position of the slipper plate can be pivoted during use to provide for alteration of the stroke of the piston.

Abrégé

An internal combustion engine which produces improved torque over known engines. The engine comprises a piston configured to move within a piston cylinder throughout a stroke cycle; a rotatable crankshaft comprising a crankshaft cam surface; a piston connecting rod pivotally connected to the piston; a crankshaft timing rod pivotally connected to the piston connecting rod at a conrod joint and to the crankshaft; a rocker arm configured to contact the crankshaft cam surface during its rotation cycle and to the conrod joint to move same 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 and at its position of maximum displacement within the piston cylinder to slow the travel of the piston through the TDC and maximum displacement positions during the piston stroke for a predetermined angle of rotation of the crankshaft.
