Abstract
An efficient and powerful engine is obtained by incorporating within an engine housing at least one cylinder which is rotatable along the inner circumferential surface of the housing. The cylinder is mounted to a crank case. A piston rod extends from the piston and is moveable longitudinally within the cylinder. The piston rod in turn is connected to a crankshaft. Thus, when the engine is powered, both the cylinder and the crankshaft can rotate, either in the same direction or in opposite directions. An exhaust opening is provided at a location substantially at the top portion of the cylinder. A corresponding exhaust port is provided in the housing, so that when the cylinder is rotated to the particular location along the housing, its exhaust opening comes into alignment with the exhaust port of the housing so that the exhaust gases resulting from the combustion in the cylinder are evacuated directly outside of the housing. A gear mechanism converts the rotational movement of either the cylinder, the crankshaft, or a combination of both, to drive the vehicle, or power generating device, to which the engine is adapted.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
