Abstract: A choke valve is controlled finely suited to the running state of an engine. A throttle valve 8 and a choke valve 9 are provided in series on an intake pipe 6, and the opening degree of the choke valve 9 is controlled by a stepping motor. The choke valve opening degree upon start of engine (start opening degree) is determined depending on the engine temperature. The stepping motor 11 is initialized at the fully closed side of the choke valve 9 when the power source for starting the engine is turned on. The start opening degree of the choke valve is judged to be closer to the fully closed side or fully opened side, and the stepping motor 11 is initialized at the fully closed side if judged to be close to the fully closed side, and at the fully opened side if at the fully opened side.

Abstract: A carburetor arrangement is provided for an internal combustion engine that is to be started with a pull cord. A fuel channel that is connected with a fuel-filled storage space opens into and supplies fuel to an intake channel portion as a function of the underpressure in the intake channel portion. The underpressure in the intake channel portion is increased during the start-up process via a start-up mechanism. To keep the engine ready to run with the start-up mechanism engaged, a control valve is disposed between the storage space and where the fuel channel opens into the intake channel portion. The control valve is opened or closed by a control unit as a function of the speed of the internal combustion engine.

Abstract: An automatic priming system for internal combustion engines, which is operable at engine cranking speeds and which is automatically disabled at engine running speeds. The automatic priming system is driven by pressure fluctuations within the engine crankcase which are caused by reciprocation of the piston. At engine cranking speeds, fluid communication between the engine crankcase and a chamber is substantially equalized, such that positive pressure pulses from the crankcase air space pass from the chamber through a check valve to the carburetor for priming. At engine running speeds, communication between the crankcase air space and the chamber is restricted such that the pressure within the chamber is below atmospheric, positive pressure pulses are not present within the chamber, and the priming function is automatically disabled.

Abstract: An automatic choke for a small internal combustion engine uses an air vane responsive to an air flow created by a radial fan to position the choke valve during engine starting. A return spring or gravity may be used to reset the automatic choke after the engine has been stopped. The automatic choke includes a thermally-responsive device that keeps the choke at least partially open during hot restarts of the engine.

Abstract: The invention is directed to a start-assist device on a membrane carburetor of an internal combustion engine in a motor-driven chain saw which is to be started manually. The carburetor includes a control chamber delimited by a control membrane. The control chamber is supplied with fuel from a fuel tank via control valve. The control valve is opened by the control membrane when the underpressure builds up in the control chamber so that fuel flows in. This fuel is supplied to the air-inducting intake channel via an idle nozzle and a main nozzle. The fuel feed system further has an outlet for vapor bubbles or the like. A pump which is driven indirectly from the start operation is provided and has a suction connection connected to the outlet in order to ensure, with few start attempts, a reliable start of the engine independently of the temperature state of the engine and other influences.

Abstract: An automatic starting arrangement for a hand-started internal combustion engine is disclosed. Internal combustion engines of this type have a choke flap and a throttle flap positioned one behind the other in the air-intake channel. In order to ensure a reliable starting of the engine independently of manual positioning activities, the invention provides that in the start position the choke flap is coupled with the throttle flap in a position-dependent manner and the choke flap holds the throttle flap in a position between the full-throttle position and the idle position. The choke flap is brought into an at-rest position via an actuating device which is actuable in dependence upon the operating condition of the engine. The choke flap is decoupled from the throttle flap in the at-rest position.

Abstract: In automatically stopping and restarting an engine on the basis of the operating conditions of various parts in a vehicle, the automatic engine stop and restart are effected by cutting off a fuel system, but not cutting off an iginition system. More specifically, a fuel control valve is provided in a path for feeding fuel to a slow port, and this control valve is closed on condition that at least the vehicle speed is in the state of zero and other conditions of allowing the automatic engine stop and restart are not met. An ignition signal taken from the energized ignition system is used to ensure that the engine is not started when it is already running.

Abstract: An engine comprises a combustion chamber and interior walls which define a fuel induction passage having a fuel outlet port communicating with the combustion chamber. A first fuel delivery system introduces fuel from a fuel source into the combustion chamber. A second fuel delivery system includes a nozzle which extends into the fuel induction passage adjacent to the fuel outlet port and is selectively operable by means of an associated valve mechanism for introducing fuel from the source directly into the combustion chamber through the nozzle in addition to the fuel which is introduced into the combustion chamber by the first fuel delivery system.
