Internal combustion engine , improvements in design and efficiency

摘要

The converting of linear motion into rotational energy when using the cylinders and pistons of an internal combustion engine without the use of a crankshaft.;The replacement with dual high lead cam-screws and dual cam-followers allows for the efficient use of a complete combustion stroke without the resistance from the crankshaft at top dead center, and a greatly reduced resistance for the return stroke as there is no crankshaft turning resistance at the outer limit of the piston stroke.

主权项

1. A horizontally opposed engine that uses a stepped piston assembly in which two stepped pistons are connected via a central shaft device comprising: a central shaft that is free to rotate at its central axis at all times, and translates linear motion into rotational energy by an overrunning clutch transitorily fixing a position of one half of the central shaft followed by the transfer of energy to dual cam-followers acting on dual spiral high lead slotted cam screws that permit a thick-wall tube to rotate; which then creates a toothed gear wheel on its axis to transmit its rotation to a transmission; whereupon the overrunning clutch releases its fixation; wherein the stepped piston is two pistons in one disposed in different sized cylinders having their own intake and exhaust valves and spark plugs.
