An oil reservoir chamber 22 in an engine E is formed into a tubular shape having annular corner portions 22a and 22b at opposite ends, and an oil slinger 25 is secured to a crankshaft 13 and has two splashing blades 25a and 25b with their tip ends being in proximity to the corner portions 22a and 22b, so that a lubricating oil in the oil reservoir chamber 22 is splashed by at least one of the two splashing blades 25a and 25b during rotation of the oil slinger 25 with any operative position of the engine E. Thus, a lubricating oil mist can be produced with any operative position of the engine E by the oil slinger of a simple structure including the two blades.

System for producing lubricating oil mist in engine

An air-cooled internal combustion engine has a cylinder block, a piston slidably disposed in a cylinder in the cylinder block, and a cylinder head mounted on the cylinder block and having a partly spherical combustion chamber aligned with the cylinder. An intake valve, an exhaust valve, and a spark plug which are mounted in the cylinder head are oriented radially outwardly from the axis of the cylinder and angularly spaced from each other by distances that are progressively increased in the direction along the axis of the cylinder. The intake valve, the exhaust valve, and the spark plug have respective central axes inclined at the same angle to the axis of the cylinder, and the intake valve, the exhaust valve, and the spark plug are angularly spaced at equal angular intervals as viewed along the axis of the cylinder.

Internal combustion engine

A fuel and lubricating oil mixing system designed primarily for two-cycle engines. Lubricating oil and fuel are stored in separate containers and mixed prior to entering the carburetor. Fuel flow is monitored by flow detector which relays information to a control unit. This unit in turn controls valves and pumps, mounted on both lubricating oil and fuel lines, in order to maintain a preferred mixture ratio regardless of engine speed or fuel flow rate. Such control ratio makes possible maximum convenience and performance with minimum engine wear.

Fuel mixing and supplying apparatus for internal combustion engines

An engine for a small vehicle of the two-stroke type having a separate balance chamber with a wall between the crankshaft chamber and the balance chamber. The balancer includes weights whose path of rotation are displaced to either side of the path of rotation of the crankweight. The intermediate wall between chambers includes three sections to accommodate the path of travel of the balancer weights to either side of the crank weights.

Balancer device for a reciprocating engine

A three-wheeled motor vehicle including one steerable front wheel, two rear wheels serving as driving wheels, a fuel tank disposed on an upper portion of a frame, a seat disposed behind the fuel tank, and an engine mounted below the fuel tank. The above engine is a water-cooled engine. A cylinder portion of the engine is disposed on the rear side in the longitudinal direction of a case portion of the engine which case portion underlies the cylinder portion, and a radiator is disposed within a space formed in front of the cylinder portion. By the above arrangement, a large space is ensured in front of the cylinder portion without the need to enlarge the longitudinal size of the three-wheeled motor vehicle, and cooling devices can be disposed within such space.
