- the edge distance D between the following edge 42 of the leading pole piece 36 and the following Edge 46 of the core at 44 is approximately 6.25 mm at 8000 rpm.
- the Walbro module MA-12 is started on an electrically Thread cutter motor manufactured by John Deere Consumer Products Inc., Charlotte, North Carolina, US used, but has not yet been used manually started manual starter motor used.
- the internal combustion engine 10 a housing part 50 which on the frame 11 above the Rotor 20 is attached.
- the housing part 50 has one Installation device 52.
- the mounting device 52 has one Recess 54, which allows the connecting element 40, to get through the housing part 50.
- the mounting device 52 also carries the starter disk 24 rotatably.
- the starting system also has a spring-receiver assembly 56 which between the starter disk 24 and the housing part 50 is inserted.
- the spring-transducer assembly 56 tensions the Starter disk 24 in a starting position based on the Housing part 50 before.
- the starter disk 24 has one Starter rope or actuator notch 58 and one Starter pawl tooth 60 on.
- the actuator 26 is around the starter disk 24 in the actuating means notch 58 wound and extends from a recess (not shown) in the housing part 50, where it is attached to a pull handle (not shown) is attached.
- the actuator notch 58 has an outer diameter E and an inner diameter F. In In a preferred embodiment, the diameter is E. about 8.57 cm (3.375 inches) and the diameter F about 6.35 cm (2.5 inch). In comparison, the diameter E is only about 6.6 cm (2.6 inch) and the diameter F only about 3.81 cm (1.5 inch) in a known prior art Starter disc. Therefore, the starter plate 24 has one Actuator notch 58 with an enlarged diameter based on the state of the art.
- actuating means notch 58 is intended to include a outer diameter or circumference of the actuating means notch 58 is understood to be greater than 6.86 cm (2.7 inches).
- the Starter pawl teeth 60 are adapted to selectively in spring-loaded starter pawls to engage the rotor 20. Such a rotor 20 is described in US 5,600,195 which are hereby incorporated by reference in their entirety is. If the pull handle (not shown) by a Operator is pulled to the engine 10 to start, this pulls on the actuating means 26. Since the Actuating means 26 is attached to the starter disk 24, the starter washer 24 on the mounting device 52 turned.
- the actuator notch 58 with enlarged diameter reduces the effort of one Operator essential if this is the actuating means 26 pulls to start the engine 10 since the Starter disk 24 with a larger diameter a larger one provides mechanical advantage to the Internal combustion engine 10 to rotate as to the state of the Technology-related starter disc with a smaller diameter.
- Starter disk 24 with a larger diameter there is a problem with using one Starter disk 24 with a larger diameter.
- a Starter disc 24 with a larger diameter will if on a state of the art Internal combustion engine is used, the internal combustion engine is not turn fast enough to cause a usual to turn State of the art pull start ignition module ignites, and as a result, the internal combustion engine will not start. Self if such a manual, belonging to the prior art Pull start ignition module would ignite at low speed, would almost certainly be a big setback occur.
- the ignition module 22, which is adapted thereto is the spark plug 18 at low rotor speeds, such as 400-700 RPM, and which has an ignition delay has low engine speeds to prevent kickback.
- the ignition module 22 alone does not do much at, the starting ability of the engine 10 to improve. Instead, it is the combination of the ignition module 22 with the starter disk 24 with an enlarged diameter, which the starting of the engine 10 essential improved.
- the combination allows that when pulling the Actuating means 26 for starting the internal combustion engine 10 less force is used.
- the combination allows that the actuating means 26 at a lower speed is pulled as in the prior art to the Start internal combustion engine 10.
- the combination causes that pulling the actuating means 26 for Operator feels softer and practically none Has setback.
- TDC top dead center
- the actuation means 26 can only be pulled at about 1.8288 m / s (6 ft / sec) to the Starting engine 10.
- an outer diameter of the actuating means notch of about 6.6 cm (2.6 inch) and a starting speed of about 640 rpm which is necessary to start the internal combustion engine must be Actuators pulled at approximately 2.2128 m / s (7.26 ft / sec) become. Therefore, the actuator 26 with the present invention above 0,3048 m (1 foot) per second pulled more slowly to the engine 10 too start than in the prior art.
- FIG. 4 there is shown a graph of the output of the ignition module 22 with respect to the starting speed of the rotor 20 for both the output voltage OC in kilovolts represented by the line G and a secondary output via a 0 , 5 M ⁇ load, represented by the line H from test measurements.
- the keyway 32 on the rotor 20 can be displaced.
- the keyway angle B (see FIG. 2) is approximately 35 degrees. With reference also to the test results from FIG. 5 for the ignition setting of such a prior art rotor, this is shown in line I when the distance is ignited at 10 kV.
- line J has a rotor with a keyway angle B of approximately 42 degrees.
- the ignition delay is much lower at low speed, creating a Low speed kickback is reduced, and a lower ignition delay or an advance at high Speed is achieved.
- the rotor 20 with the keyway angle B of 42 degrees allows the rotor and ignition module setting to be one comparable ignition timing of 0 degrees at 7000 rpm and about -8 degrees at 500 rpm related to the 0 degrees at 7000 rpm too to have.
- the state of the art as shown in line K has 0 degrees at 7000 rpm and about 0 degrees at about 600 rpm based on the 0 degrees at 7000 rpm.
- the ignition module 22 allows a slower hand start and it is indifferent how slowly the actuating means 26 is pulled, no Setback possible.
- the ignition module 22 may have an ignition delay of about 8 degrees at the minimum cranking speed of the rotor 20 Make available.
