Abstract: PURPOSE:To lower the specific fuel consumption of an internal-combustion engine, by employing such an arrangement that power is produced in an air feeding pump driven by an engine and the power is transmitted to the engine at the time of partial-load operation of the engine including racing operation of the same. CONSTITUTION:An engine of this invention comprises a pump 2 driven by the engine via a power transmitting means such as chain. Air drawn from an intake passage 9 along with rotation of the pump 2 is supplied to the engine via discharge passages 10, 11. Here, the suction volume of the engine per one turn is made equal to the discharge volume of the pump 2 so that the engine is not supercharged. Further, arrangement is such that a slit 8 of a rotor 3 is communicated with an intake passage 11 and communication between the starting point 14 of the intake passage 10 and a work chamber 7 of the pump 2 is borken when the volume of the work chamber 7 is changed from maximum to minimum at the time of racing operation of the engine when a throttle valve 13 is closed completely.

Abstract: PURPOSE:To reduce the loss of fresh air considerably in the middle speed region by forming an auxiliary chamber which is conducted through a throttle valve to the crank chamber thereby performing good scavenging function in the high speed region of engine. CONSTITUTION:Upon closing of a scavenge path 4 in the lifting process of a piston 1, the suction gas is sucked into the crank chamber 3 while upon transfer to the lowering process the suction gas sucked into the crank chamber 3 is compressed while being throttled by a throttle valve 9 and flowed into an auxiliary chamber 8. Assuming the pressure in the crank chamber 3 when the scavenging path 4 will be opened is P, it will be higher as the engine speed region is higher. In the low engine region, the pressure P is low to reduce the injection speed of the fresh air to be injected from the scavenge path 4 thus to perform the scavange function gradually and to reduce the pass through loss of the fresh air considerably.

Abstract: PURPOSE:To decrease the total height of a carburetor, by heightening the mixture concentration of the carburetor in the starting and cold running of an engine without using a choke valve. CONSTITUTION:Sucked air sent from a pump 22 has its pressure regulated to a prescribed level by a constant pressure valve 23 and then jets out at a high speed through an orifice 30 and an ejecting section 31 so that intense negative pressure is caused at a pressure drop section 32. Since the negative pressure in a pressure introducing chamber 21 is made more intense than conventional cases and a sucked air flow rate detector 6 heightens the degree of opening of a Venturi valve 4, the effective cross-sectional area of a fuel jet 9 is made larger than the conventional cases so that the mixture concentration of a carburetor is increased in the starting and cold running of an engine. The high speed of the flow jetting from the ejecting section 31 is controlled by the orifice 30 and a regulating rod 29 depending on the temperature of the engine.

Abstract: PURPOSE:To prevent any reflux starting from a working chamber into a suction passage by ejecting a high speed stream during an interval from proximity of a time at which capacity of the working chamber in a suction stroke is maximum, to proximity of a time at which communication between the working chamber and the suction passage is shut off. CONSTITUTION:In a high load range, a pump throttle valve 12 and closing valve 16 are fully opened, while a pump passage 11 is opened by a suction cut-off valve 13 for a certain duration within an interval from proximity of the time when the capacity of a working chamber 3 in a suction stroke is maximum, namely, when a piston reaches a bottom dead center, to proximity of the time when communication between the working chamber 3 and the suction passage 6 is shut off, namely, when a suction valve 4 is closed. The suction air fed under pressure from a pump 10 is thus ejected at a high velocity from a nozzle 15.

Abstract: PURPOSE:To stably rotate an engine, by providing a control valve in an intake discharge passage communicating an intake passage and a working chamber. CONSTITUTION:When a throttle valve 8 is opened from a minimum opening position to an optional opening theta, negative pressure in a small Venturi 9 is temporarily decreased, and a control valve 13 is placed in a fully opened condition. In this way, an intake air quantity charged in a work chamber 4 is increased, then if speed of an engine is increased while an intake quantity is increased, the negative pressure in the small Venturi 9 is increased, consequently the control valve 13 is turned in the direction of opening, and the speed of the engine in accordance with an opening of the throttle valve is obtained. When the throttle valve 8 is maintained to the opening theta, if the speed of the engine is increased by some cause, the negative pressure in the small Venturi 9 is increased, consequently the opening of the control valve 13 is increased, and if the speed tends to decrease, the opening of the control valve 13 is decreased, and the engine is intended to be in a stable speed.

Abstract: PURPOSE:To reduce heat capacity in a combustion chamber, by reducing density of a charge air to be supplied to an engine under greatly low load including an idling condition, and thereby reducing weight of the charge air to be filled in a cylinder. CONSTITUTION:Under greatly low load including an idling condition, an openable valve 13 is fully closed. A charge air is fully supplied through a passage 8 on a pump suction side into one operation chamber 7 from its minimum volume condition to its maximum volume condition. In such a course as from a medium volume condition to the minimum volume condition of the operation chamber 7, the operation chamber 7 starts to be communicated with a passage 10 on a pump dischrage side to supply the charge air in the operation chamber 7 to the engine. On the other hand, in such a course as from the maximum volume condition to the medium volume condition of another operation chamber 7, the charge air is returned through a return passage 11 to the passage 8 on the pump suction side. From near a position where the return passage 11 is closed, the operation chamber 7 starts to be communicated with the passage 10 on the pump discharge side.
