- the turn-on speed of the rotor for the discharge is between about 400-700 rpm with a typical rise time of about 3 milliseconds.
- 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 about 6.25 mm at 8000 rpm.
- the Walbro module MA-12 is powered by an electric Motor of a thread cutter, manufactured by John Deere Consumer Products Inc., Charlotte, North Carolina, US used, but not yet on a manual only started hand-cranked engine used.
- the engine 10 has a housing part 50, which on the frame 11 above the Rotor 20 is mounted.
- the housing part 50 has a Mounting device 52 on.
- the mounting device 52 has a Recess 54, which allows the connecting member 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, the between the starter disk 24 and the housing part 50 is inserted.
- the spring-picker assembly 56 biases the Starter disk 24 in a starting position relative to the Housing part 50 before.
- the starter disk 24 has a Starter cable or Betuschistskarkerbe 58 and a Starter left locking tooth 60 on.
- the actuating means 26 is around the starter disk 24 in the actuator groove 58 wound and extends from a recess (not shown) in the housing part 50, where it on a pull handle (not shown) is mounted.
- the actuating means 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 inches). In comparison, the diameter E is only about 6.6 cm (2.6 inches) and the diameter F is only about 3,81 cm (1.5 inches) in a known belonging to the prior art Starting pulley. Therefore, the starter disk 24 has a Actuator notch 58 with an enlarged diameter based on the prior art.
- Actuator notch with enlarged diameter is intended to be that including a outer diameter or circumference of the actuating means notch 58 which is larger than 6,86 cm (2,7 inches).
- the Starting link locking teeth 60 are adapted to be selectively in spring-loaded starter latches on the rotor 20 engage. 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 internal combustion engine 10th to start, this pulls on the actuating means 26. Since the Actuator 26 is attached to the starter disk 24, the starter disk 24 is on the mounting device 52nd turned.
- the starter left-hand locking teeth 60 are starting to jolt engage the rotor 20, the rotor 20 with the Starter disk 24 is rotated (at least until the engine 10 starts and starters jerk by centrifugal force moved outside).
- the actuating means notch 58 with increased 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 enlarged diameter larger mechanical advantage provides to the To rotate internal combustion engine 10, as with the state of the Titan belonging smaller diameter starter disk.
- starter disk 24 with a larger diameter there is a problem with using a Starter disk 24 with a larger diameter.
- a Starter disk 24 with a larger diameter if They belong to a state of the art Internal combustion engine is used, the internal combustion engine is not turn fast enough to cause a usual to The prior art Anlagenstartzündmodul ignites, and As a result, the engine will not start. Even if such belongs to the prior art, manual Train start ignition module would ignite at low speed, would almost certainly be a big setback occur.
- the ignition module 22, which adapted thereto is the spark plug 18 at low rotor speeds, such as 400-700 rpm, to ignite, and which one ignition delay at low speeds to prevent a setback.
- the use of the ignition module 22 alone does not contribute much in, the starting capability of the internal combustion engine 10 to improve. Instead, it is the combination of the ignition module 22 with the larger diameter starter disk 24, which the starting of the internal combustion engine 10 substantially improved.
- the combination allows dragging the Actuating means 26 for starting the internal combustion engine 10th less force is spent.
- the combination allows that the actuating means 26 at a lower speed is drawn, as in the prior art, to the To start combustion engine 10.
- the combination causes the pulling of the actuating means 26 for the Operator feels softer and virtually none Setback.
- the ignition module has 22 two desirable features. For one thing, it will be one Ignition voltage that is high enough to the spark plug 18th to ignite when the rotor 20 with a relatively small Speed (about 500 rpm) turns. Second, the Ignition module 22 an ignition delay at low speed (about 8 degrees at 500 rpm), which is the spark plug 18 closer to the top dead center (TDC) ignites; thereby the setback is minimized.
- the two features mentioned above make use of a starter disk 24 with a larger diameter possible.
- the actuating means 26 can only be pulled with about 1.8288 m / s (6 ft / sec) to the To start combustion engine 10.
- an outer diameter of the actuating means notch of about 6.6 cm (2.6 inches) and a starting speed of about 640 rpm, which is necessary to start the engine, that must Actuator pulled at about 7.2128 m / s (7.26 ft / sec) become. Therefore, the actuating means 26 with the present invention over 0.3048 m (1 foot) per second be pulled slower to the internal combustion engine 10 to start, as in the prior art.
- FIG. 4 there is shown a graph of the output of the ignition module 22 relative to the starting speed of the rotor 20, for both the output voltage OC in kilovolts represented by the line G and a slave output over a zero , 5 M ⁇ load, represented by the line H from test measurements.
- the keyway 32 can be offset on the rotor 20.
- the keyway angle B (see FIG. 2) is about 35 degrees. Referring also to the test results of Fig. 5 for ignition timing of such a prior art rotor, this is shown in line I at the ignition of the 10 kV spacing.
- the ignition delay is at low speed much larger, creating a Backlash at low speed is reduced, and a lower ignition delay or a lead at high Speed is achieved.
- the rotor 20 with the keyway angle B of 42 degrees allows the rotor and ignition module setting, a comparable ignition timing of 0 degrees at 7000rpm and about -8 degrees at 500rpm relative to 0 degrees at 7000rpm to have.
- the state of the art, as shown in line K, is 0 degrees at 7000 rpm and about 0 degrees at about 600 rpm based on the 0 degree at 7000 rpm.
- the ignition module 22nd allows a slower handstart and it is, indifferent how slowly the actuator 26 is pulled, no Setback possible.
- the ignition module 22 an ignition delay of about 8 degrees at the minimum starting speed of the rotor 20 to Make available.
