Abstract
Abstract An improved two-cycle Diesel internal combustion engine is provided, whereby the intake and exhaust port passages are modified to provide greater circulation of the combustible fluids and air during the intake and exhaust cycles of the Diesel engine, respectively. The intake passages are so located in each piston and each cylinder to provide communication thereinbetween during the intake cycle with the piston at the bottom of its stroke which effects the exhaust cycle simultaneously substantially similar to a normal two-cycle operation. The intake passages in each cylinder communicate with intake passages in each piston which are connected to an intake flume port located epicentrically in the upper portions of each piston. The movement of the combustible fluids and the evacuation air is directed from the intake flume port and deflected off a conical protrusion in the upper surface of the cylinder, in order to promote circulation of the combustible fluids and the evacuation air, respectively.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
251 words
An improvement to an internal combustion engine having at least one cylinder and piston, including intake passages, and exhaust passages for the transformation of combustible fluids and input gas into released energy and evacuated exhaust fluids, wherein the improvement comprises: (a) an exterior cylindrical surface of said piston having a plurality of intake ports therein; (b) an exterior compression surface of said piston having means for projecting new input gas in a direction orthogonal to said exterior compression surface, and further having a recessed area to cooperate with said projecting means to enhance compression within the cylinder, said projecting means comprising a flume port for controlled projecting of the new input gas; (c) an interior compression surface of said cylinder for deflecting the new input gas convexly within the bore of said cylinder, said interior compression surface having a combustible fluid injection port therein and said exterior compression surface extending on upward stroke to a point where said flume port is physically apart from association with said interior compression surface; and (d) an interior cylindrical surface of said cylinder having a plurality of intake outlets and a plurality of exhaust ports, said exhaust ports closer to said interior compression surface than said intake outlets and said intake ports of said exterior cylindrical surfaces of said piston, said intake outlets and said intake ports communicating during the intake-exhaust cycle whereby the input gas is rapidly introduced and forcefully injected as a flume into the cylinder to flush and evacuate the exhaust fluids.
Claim 2
Dependent Claim
251 words
An improvement to an internal combustion engine having at least one cylinder and piston, including intake passages, and exhaust passages for the transformation of combustible fluids and input gas into released energy and evacuated exhaust fluids, wherein the improvement comprises: (a) an exterior cylindrical surface of said piston having a plurality of intake ports therein; (b) an exterior compression surface of said piston having means for projecting new input gas in a direction orthogonal to said exterior compression surface, and further having a recessed area to cooperate with said projecting means to enhance compression within the cylinder, said projecting means comprising a flume port for controlled projecting of the new input gas; (c) an interior compression surface of said cylinder for deflecting the new input gas convexly within the bore of said cylinder, said interior compression surface having a combustible fluid injection port therein and said exterior compression surface extending on upward stroke to a point where said flume port is physically apart from association with said interior compression surface; and (d) an interior cylindrical surface of said cylinder having a plurality of intake outlets and a plurality of exhaust ports, said exhaust ports closer to said interior compression surface than said intake outlets and said intake ports of said exterior cylindrical surfaces of said piston, said intake outlets and said intake ports communicating during the intake-exhaust cycle whereby the input gas is rapidly introduced and forcefully injected as a flume into the cylinder to flush and evacuate the exhaust fluids.
Claim 3
Dependent Claim
37 words
An improved internal combustion engine according to claim 1 wherein the interior compression surface of each cylinder includes means in conjunction with the surface for deflecting the new input gas convexly within the bore of said cylinder.
Claim 4
Dependent Claim
41 words
An improvement to an internal combustion engine according to claim 1 wherein the exhaust ports are positioned so as to be uncovered by the piston before the intake ports as the piston moves in its downward stroke during the combustion cycle.
Claim 5
Dependent Claim
65 words
An improvement to an internal combustion engine according to claim 3 wherein each said intake port has a tangentially converging slot and said exterior compression surface has an intake flume port concentrically adjacent to said input gas projecting means and vertically communicating with said tangentially converging slots, whereby the input air is directed into the bore of the cylinder orthogonally to said exterior compression surface.
Claim 6
Dependent Claim
43 words
An improvement to an internal combustion engine according to claim 3 wherein each said intake port is channeled substantially adjacent to said exterior compression surface whereby the input air is directed into the bore of the cylinder orthogonally to said exterior compression surface.
