Benefits of technology

[0004]Removing the camshaft and valves would improve the four-stroke engine through a reduction in moving parts and through improved airflow, which would translate to better fuel economy and horsepower gains. A rotating shaft, timed just right, with a cross-hole through it, or multiple cross-holes, would allow airflow in or out without having the restrictive nature associated with present day design.

Problems solved by technology

Valves are very restrictive to linear airflow, and airflow has to bend to get around the intake valve to get into the combustion chamber.
In addition to valves often being a weak component of the internal combustion engine, the bending of this airflow around the intake and exhaust valves creates inefficiencies.

Embodiment Construction

[0028]FIG. 1 depicts a typical piston cylinder arrangement for a single- or dual-overhead cam arrangement whereby the valves permit entry and exit of air. In this arrangement, the valves are integral to the operation of this four-stroke engine. For the four-stroke engine, the first stroke is the piston moving in a downward motion, and the intake valve 110 of FIG. 1 is open to permit air entry. On the upward stroke of the piston, the valves are closed. On the third stroke, the piston is moving in the downward direction and, at the same time, the valves are still closed. Near the bottom of the power stroke, the exhaust valve 120 opens, allowing spent gases to exit during the fourth (exhaust) stroke. Typical single- or dual-overhead cam arrangements show a hemispherical chamber, cylinder, piston, connecting rod, and valve arrangement whereby an intake valve (left) and exhaust valve (right) introduce air into the engine and permit the exit of combustion byproducts. In this design, the s...

Abstract

In one embodiment, an improvement to a four-stroke engine having a single cylinder block arrangement including an engine block, timing gears, crankshaft and gear, timing belt/chain, intake port, exhaust port, and cylinder head arrangement includes a ported rotating shaft, the ported rotating shaft having a first port, the ported rotating shaft synchronized with the crankshaft, such that the first port periodically aligns with the intake port to allow for intake during the four-stroke cycle.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This Application claims the benefit of U.S. Provisional Patent Application No. 61 / 308,841 filed on Feb. 26, 2010, which is hereby incorporated by reference.BACKGROUND[0002]The internal combustion engine has remained mostly unchanged for the past 100 years with most advancements emanating from improvements in fuel injection (e.g., direct fuel injection), variable valve timing, camshaft design, and emissions controls. However, every four-stroke engine manufactured in the past 100 years is pretty much the same configuration. They all use crankshafts, connecting rods, pistons, and rings in the block area. There are slight variations in the head and intake area, but most use camshafts, valves, valve springs, retainers, etc. Some use lifters, pushrods, and rocker arms, some use followers, and some use the camshaft pushing right over the valve with a “bucket” on top of the valve. However, they all use camshafts and valves.[0003]Valves are very r...
