Latest Patents

One of Abe's latest patents is for a camshaft designed for engines. This invention features an improved and simplified outboard motor construction, wherein the cooling and exhaust systems are formed with a minimum number of components and sealing joints. It incorporates a non-metallic camshaft, which reduces both cost and weight without sacrificing durability. The exhaust system includes an elongated expansion chamber formed in the drive shaft housing. Additionally, the drive shaft housing has a cylindrical section that is journaled within a swivel bracket for steering movement. The volume between the external portion of the drive shaft housing and the internal portion of the swivel bracket forms a second expansion chamber, which is utilized for low-speed above-water exhaust gas discharge. The flow of cooling water to and from the engine is controlled to ensure that the exhaust gas interchange area between the power head and the drive shaft housing is well-cooled, along with the oil reservoir for the engine and the oil returned to it.

Another significant patent is for a marine propulsion engine. This invention includes embodiments of outboard motors that have separate electrical generators driven by the engine output shaft from the magneto generator. The protective cowling and engine induction system are configured to prevent air flowing to the induction system from crossing over the electrical power generator, thus protecting it from corrosion caused by water in the air inducted to the engine.
