Abstract: The present invention provides a device for controlling the air/fuel mixture ratio during the starting period for an outboard motor. Specifically, a positive temperature coefficient (PTC) heater controls a fuel flow regulating valve at an engine's charge forming device. A multipolar generator is used as an exclusive power source for the PTC heater. The arrangement of the invention has a relatively simple construction and can be used with propulsion units which do not have batteries.

Abstract: An intake system for an internal combustion engine having an air/fuel ration control device for closing the vent on a float chamber. The increased pressure within the float chamber from the incoming fuel enrichens the air/fuel mixture to the engine. The vent closure is effected by a valve controller responsive to intake vacuum. The controller is activated by vacuum experienced during engine braking. A bistarter choke system is disclosed including means for disabling the air/fuel ratio control device using either a switching apparatus or the higher pressures within the choke mechanism.

Abstract: An improved two-barrel, multi-fuel carburetor. The carburetor comprises a main body portion in which the main fuel bowl is positioned and an auxiliary body portion in which an auxiliary fuel bowl is positioned. All of the fuel and air passages extending between the main and auxiliary body portions extend through faces of the respective body portions that are in facing engagement when the auxiliary body portion is affixed to the main body portion so as to eliminate the necessity for external plumbing. Also, an improved arrangement is provided for preventing the discharge of fuel from the auxiliary fuel discharge under some engine running conditions. The carburetor also employs a simplified accelerating pump discharge that uses only a single accelerating pump discharge tube that extends completely through one of the induction passages and which terminates in the other induction passage and has discharge ports in both induction passages.

Abstract: An apparatus for enriching an air-fuel mixture supplied by a carburetor upon starting operation of an internal combustion engine comprises a fuel quantity increasing passage which is operative independent of main fuel supply system. The passage has an inlet communicated to a fuel supply source and an outlet opened at a location downstream of a throttle valve. The amount of fuel ejected from the outlet of the passage is controlled by a control signal which represents a product of a value variable in dependence on a suction vacuum, the rotational frequency of the engine and a value variable in dependence on the temperature of engine cooling water.
