    摘要: The invention relates to a method and an apparatus for reducing to a minimum the predominant full load noise of port-controlled, two-stroke internal combustion engines by constructing the lower suction port boundary and the lower piston boundary, so that there is a gradual port opening during the upward movement of the piston and a gradual port closing during its downward stroke.

    摘要: Several embodiments of fuel injection controls for two-cycle crankcase compression internal combustion engines. In each embodiment, the fuel injection is controlled by measuring the amount of air inducted through measurement of the pressure generated in the crankcase. In each embodiment, abnormal pressure variations in the crankcase not due to the amount of air inducted are eliminated by measuring the pressures at predetermined crankshaft angles. In some embodiments, this is done through the use of a valving arrangement and in other embodiments, this is done electronically.

    摘要: The invention relates to a method and to a port-controlled two-stroke internal combustion engine in which the cross-sections of the intake and outlet are so constructed in the direction of the longitudinal axis of the cylinder that in the case of an upward or downward movement of the piston, the noise-generating intake and outlet pressure gradients and amplitudes are reduced by the gradual opening of the particular intake and outlet, the piston lower edge and intakes having special constructions.

    摘要: A coal dust combustion motor comprises a piston reciprocatable in a cylinder and connected at one end by a connecting rod to a crankshaft of the motor for rotating the crankshaft during reciprocation of the piston along a sucton and a compression stroke. A cylinder space is defined between the other end of the piston and a facing end wall of the cylinder. A whirling chamber communicates in the region of the cylinder end wall with the cylinder space and a mixture of coal dust and air is blown at a pressure of about 5-7 bar into the whirling chamber during the compression stroke of the piston at a time at which the pressure in the cylinder space is greater than that in the whirling chamber to prevent penetration of coal dust into the cylinder.

    摘要: An air and fuel induction system for a two cycle engine having two adjacent horizontal cylinders positioned aligned one above the other and each having a separate closed crankcase includes a single horizontally positioned carburetor having a single metering system for supplying an air and fuel mixture to both cylinders. An induction passageway for each cylinder connects between the carburetor and each crankcase. Each induction passageway has an opening at about the same elevation and each opening has about the same cross sectional area. A reed valve is positioned adjacent the carburetor throat and at the entrance to each of the induction passageways. The reed valve includes at least one flat reed positioned directly across and closing the opening to each of the induction passageways.

    摘要: A two-cycle engine (10) has an idle fuel system which admits fuel-air mixture into the transfer passages (22). Heated air is supplied to the idle mixing passage (42) by a serpentine air passage (45), while fuel from the carburetor float bowl (33) is supplied through a needle valve (50). A reed valve (43) admits the idle mixture to the transfer passage (22).
