    摘要： A reciprocating impact tool such as a rammer or a breaker is provided with a lubricating oil supply system that supplies lubricating oil to a fuel supply line of the tool's two-cycle engine, thereby eliminating the need to premix the fuel and oil. The oil is supplied at a rate that varies with the speed of the reciprocating member of the tool, thereby assuring that the fuel and oil are mixed in the proper proportions. The oil pump delivers oil to the fuel supply line well-upstream of the engine's carburetor or other fuel supply device, thereby taking advantage of movement and vibration of the reciprocating member to assure that the delivered oil is thoroughly mixed with the fuel in the fuel line before the mixture is inducted into the engine's combustion chamber, leading to complete atomization of the oil and resultant benefits, including improved lubrication and complete combustion of the oil. The invention requires no modifications to the existing engine crankcase design because the oil supply system's pump is coupled to and driven by the reciprocating member's drive train as opposed to the engine.

    摘要： A lubricating-oil supply system for a two-stroke cycle engine, comprises an oil pump supplying lubricating oil from an oil tank to various areas of said engine. Said oil pump is electrically drivable by an electromagnetic solenoid. A control unit is adapted to electrically control this electromagnetic solenoid according to the operating state of the engine. This electromagnetic solenoid and said oil pump are enclosed within one case and that between one end of said case and said electromagnetic solenoid there is provided a spacer means for holding said electromagnetic solenoid in a certain distance to the first end.

    摘要： The present invention relates to a two-stroke engine and more specifically to an improved direct lubricating system of same. Moreover, it refers to a method of improving direct lubrication of a piston along a piston sliding surface (inner wall) of a cylinder by means of adding fuel to the oil directly supplied to the inner wall of the cylinder in order to dilute the oil reducing its viscosity in order to prevent carbon particles from adhering to the surface of the piston. In this way reliable lubrication of the piston can be improved keeping the piston clean.
