We broke a pick-up on the Ducati.
Lusiu To understand it, the pick-up is the part that detects the exact point where the rotation of the crankshaft on which the spark must jump. It is that black piece attached to a cable is loose. There is another set to cover housing.
Both pick-ups must be fixed to the top, located at a separation of 90 ยบ. With the top mounted, a piece that rotates with the crankshaft passes the pick-up and "excited" for it to send a signal to the switch box and connect it to ground the coil high to jump the spark the corresponding cylinder. This piece is attached to the crankshaft. Is that subject to a cylindrical piece with a flange hipertuerca on its perimeter.
means that if the cylinders are located at 90 degrees, the spark on both cylinders have to jump to 90 degrees of rotation Unlike crankshaft, so the pick-ups are at 90 degrees from each other.
As the shot is the crankshaft, it is understood that the spark will jump into each cylinder for each revolution of the crankshaft. thus, the spark when the piston is in its TDC (actually before, this is the spark advance), whether in the working stroke (with the mix compressed and closed valves) or not (in the transfer, with both valves open).
Then we have one in two sparks is useless, but it is mounted. On a Guzzi, for example, the seizure of power in him is not crank, but in the camshaft, so that only the spark when needed. But that is another story.
To which we.
The lucky pick-up passed away, and therefore only funiconaba a cylinder. And we have not been able to find a replacement. So we decided to mount a full electronic ignition, fabirc by Sachse-Electronics .
The operating principle is the same, but more modern.
First you install a plaque with the sensors (pick-ups) where the old were mounted on the top of the crankcase.
then removed the ring signal on the crankshaft ...
... and put a new cap that comes with the kit.
In this cap is screwed on its perimeter a ring that has two magnets on the perimeter. The ring is fixed to the cap by three small screws.
But all is not so simple. No better place in any position. This must be done so that the ignition timing is perfectly us.
have to adjust to the spark (with the engine off) when the horizontal cylinder is in its PMS. The system has a LED warns you that. When the LED is off, is when the spark jumps. Thus, by rotating, we can regulate it just right.
The system works like this: the first magnet passes through the detector plate, and turn on the light. The second magnet passes the sensor and turns off the light. That must be the PMS of the cylinder. With the second cylinder the same: there is a second detector which is located 90 degrees crankshaft rotation after the first.
The fuck is that to turn the disk is removing the cover, rotate, fit the lid and check again. But that are things .... Taglioni
order to "play" with the power and progress, we have had to ys brico mount ...
Above all, to detect where is the deadlock, and see that right in the PMS LED goes out (the spark).
Simple but effective.
pick.ups The signals are sent to a "black box" that is the true soul of power.
Once the engine running, the box is responsible for making, depending on engine speed, the spark to jump a number of degrees before the piston reaches its TDC (for each cylinder independently). That is, the spark advance. Thus, when the first magnet passes the detector, some time before it reaches TDC, the "black box" you know when you will have to jump the spark. Therefore suspect that the second magnet is mounted only for the purpose of regulating the system, that is, to put the little light and pointing out that this must be the PMS.
But there's more. Progress as on any bike of that size that boasts, is variable. That is, as the speed increases, the more it progresses on. It should be.
Not content with this, the "black box" offers the possibility to choose from nine power curves (power curves not, as I have heard some pellet) different.
come here and work the test driver to go testing curves and detect if there is any improvement or not the engine operation.
