Abstract: An air cleaner system that potentially reduces debris entering a prime mover (e.g., engine) during removal/replacement of an air cleaner. In one embodiment, the engine includes a shroud defining an air cleaner compartment. The engine further includes a tubular air feed port defining a combustion air intake. The air feed port terminates at an end face located at or within the air cleaner compartment, and a lower portion of the end face is notched relative to other portions of the end face. In other embodiments, an engine oil drain system is provided that selectively positions a distal end of an oil drain tube at a drain position located away from the engine. The oil drain tube may also be repositioned to a stored position, wherein the distal end of the drain tube attaches to a nipple connected to either an engine housing or surrounding structure.

Abstract: An internal combustion cylinder head is comprised of a housing formed from three sections horizontally divided along the axis of two parallel horizontal gear shafts and a horizontal parallel camshaft located above them. The valve stems pass between the gear shafts and the valve faces are located below the gear shafts. Meshing the gear shafts together and driving them from the crankshaft form the gear compressor. Internal combustion passages are formed in the housing between the air compressor and an exhaust valve. The compressor is divided into four pumps, two outer oil pumps and two middle air pumps that pump air into the combustion passages. Two internal air intake passages surround the housing enclosing the air compressor and serve to cool the cylinder head as air is drawn through them into the air compressor. When the engine is started the fuel and air pumped into the cylinder head is compressed and ignited in the combustion passages located in the cylinder head between the compressor and central exhaust valve. Compressing and igniting the fuel charge in passages in the cylinder head instead of in the cylinder allows the engine to achieve two-cycle operation. Continually forcing air into these passages increases power.
