A lubricating apparatus for an engine of vertical crankshaft type according to the present invention includes an oil pan arranged at a lower portion of a crank case for supporting a vertical crankshaft, and an oil tank having a volume larger than that of the oil pan arranged independently from the oil pan, and wherein an outlet of the oil tank is communicated with each of lubricating portions through the oil pan, an intake portion of the oil tank is communicated with the oil pan and the oil in the oil pan is fed into the oil tank by means of an appropriate oil feeding mechanism.

Lubricating apparatus for engines of vertical crankshaft type

A cam shaft for engine is constructed such that the cam shaft driven by a crankshaft is rotatably supported at both ends by respective journal bearing boxes. Either one of the journal bearing boxes is fed with pressure oil from an oil pump to cause the oil pressure gathered within the journal bearing box to act upon the end face of the cam shaft so that the cam shaft is normally biased in a constant axial direction.

Structure of cam shaft for engine

A suction air passage of the side-valve type of internal combustion engines is composed of a pipe-shaped portion which is integrated into the cylinder, for example by means of metal mold, and is opened at its outside, and a cover which is fixed to the pipe-shaped portion to close the opening thereof.

Suction air passage of internal combustion engine

A fuel supply system for a small engine including a constant level fuel chamber for receiving fuel from a fuel tank through a fuel drawing pipe to eject the fuel into a carburetor through a main nozzle after temporarily storing the fuel therein. A cover is provided to enclose the fuel drawing pipe and the constant level fuel chamber to separate the fuel drawing pipe and the constant level fuel chamber from a fuel storing section in the fuel tank, to enable fuel of a constant flow rate to be fed to the carburetor through the main nozzle irrespective of variations in the liquid level in the fuel storing section.

Fuel supply system for small engine

Engine noise attenuator for motor-propelled boats including a housing made of resilient material and having one end connected to the exhaust pipe and a perforated pipe disposed within the housing and supported by the housing wherein the perforated pipe is in communication with the exhaust pipe such that the perforations form a resonance chamber between the housing and the exhaust pipe.

Engine exhaust means for motor propelled boats

A motor-propelled boat comprising a boat hull, an internal combustion engine mounted on the boat hull through a resilient mounting and adpated to drive a propulsion unit, the engine including a body and exhaust unit connected with the body, the exhaust including a first pipe rigidly connected with the body and a second pipe connected with the first pipe through a resilient connecting unit, the second pipe being further supported through a resilient support by the body of the engine.

Vibration absorbed engine exhaust means for motor propelled boats

Power propelled boat including a boat hull and an engine for providing a propulsive force. The engine has one or more electric components such as ignition coils, voltage regulators and capacitor discharge ignition units which are housed in a casing mounted on the boat hull. The components are connected with functionally associated electric parts such as ignition plugs, generators and magnetos through wires which are connected with the components through a specially designed connector.

Power propelled boat with improved electrical connector

A magneto casing for an engine connected to an engine crankcase in liquidtight sealing relationship by means of an oil seal which permits small amounts of air to pass therethrough is formed therein with an air passage having mounted therein a filter which is repellent to water but permeable to air. When the internal pressure of the magneto casing undergoes changes due to variations in the pressure within the crankcase which occurs when the engine operates, only air is allowed to flow into and out of the magneto casing through the filter in the air passage and water is prevented from entering the magneto casing.
