farewell to points and condensor

Electronic ignition for all types of mopeds. These turned replace the points and condensors. Due to the variety of brands of magnetic flywheels and engine turns, we have different colors for better equipment and more simple setup, without altering the position of the original ignition plate. CDI units 1 – 7 have two parts (coil and CDI) included in this list as separate items all with the same 2013 CDI box

CDI with out sensor

The acronym means CDI Capacitive Discharge Ignition.
As its name implies, uses a capacitor that is charged with a given voltage and discharged on the winding high at the time required for the motor.
The sensor consists of power without a supply roll, a CDI (black box) and a high coil.
Turning the flywheel coil generates AC power which sends the CDI.
The Commission charges the capacitor with the positive half-cycles of alternating current and the negative discharge, therefore each complete cycle of alternating current results in a firing spark plug.
Fliers who work with this system consist of 4 magnets and generate 2 sinusoids per turn, so for this reason the sensor ignition system produce 2 sparks per revolution, one in PMS and another in PMI.
To achieve the right setting combines cutting flywheel key, position and polarity of the magnets, the position of the supply roll with the advance degrees required by the motor.
Due to the characteristics of the CDI are always fixed point at which they are used for 2-stroke engines and low displacements that do not require an advance curve complex.

CDI with sensor

The acronym means CDI Capacitive Discharge Ignition.

As its name implies, uses a capacitor that is charged with a given voltage and discharged on the winding high at the time required for the motor.

The ignition coil sensor consists of a supply, a CDI (black box), a sensor and a high coil.

Turning the flywheel coil generates AC power which sends the CDI.

The Commission charges the capacitor with the positive half-cycles of alternating current and maintains the current stored until it gets a pulse from the sensor. With this pulse triggers the capacitor on the coil current high generating a spark at the plug.

There are two basic types of sensors, one that sits inside the flywheel with an iron core and magnetic field takes the wheel to generate the pulses and the other is located outside the steering wheel and magnetic core is excited by a cam attached to the steering wheel to go near it generates the necessary pulse.
These CDI fixed point used in 2-stroke engines or some low displacement 4-stroke engines because other require an advance curve depending on the RPM for better performance.

voltage regulators

One of the easiest circuits to produce light on a motorcycle or moped is to connect the output of a generator coil (located inside the flywheel) the source of light through a light switch.

This coil generates AC with a frequency and voltage proportional to engine RPM.

Normally with a 4-pole flywheel generates two cycles per revolution.

If we apply a focus directly to the output of the coil will have two problems:

1 – At low RPM will have very little power and therefore our light is very low (this can be noted on mopeds when adjusting)

2 – At high RPM the coil will generate more voltage than necessary thus burn the lamp.

The first problem we can not give solution because we do not have the necessary power.

In the second case, were designed surge protectors whose function is to remove the positive and negative peaks in excess of 6 or 12 volt as appropriate.

These teams do not rectify the current, but the alternates kept stable.

Have two connections, one positive and one negative, and are applied in parallel with lighting coil.
Physically can have one or more terminals may have two positive and one negative, one positive and one mass cabinet or other combination, but always connected to the coil positive and negative light to the chassis.

we now have a nice supply of the pietcard CDI conversion sets. these CDIs are what they call sensor-less CDI. you use them with your stock points stater plate and flywheel! crazy, right? and don’t forget about all the pietcard CDI boxes we have as well. you can use these on all kinds of mopeds. + some more pietcard surprises to come.

here’s some info about the sensor-less CDI from pietcard

here’s how pietcard CDIs are made in the pietcard factory. looks pretty advanced!

Pietcard Electronics SRL Argentina is a company founded in 1990 and based in the city of Pilar, in the center of the province of Santa Fe. Proven track record guarantees the highest performance in its extensive line of products geared especially to the manufacturing of electronic ignition and voltage regulators. With excellent levels of performance, functionality and security, this being a certified ISO 9001 company, with scope to: Design, Development, Manufacture, Sale & Service of Electronic Equipment for Mopeds!

 



digital direct

you might have seen the new digital direct CDI from MVT. you might have got one already. here’s a little info, you can read about the improvements made with digital CDI over the previous analog versions.

about the digital direct compared to a analogic
the base is the same only the management of the timing is different
the analogic is manage with a curve produce by electronic composant
it’s not possible to modified it .
the digital curve is manage by a eprom mono curve it means a small computer
design by the racing service it’s integrate inside the best timing at
every 100 rpm for a model of engine.

the analogic variation give a better result of engine power than a fix ignition
and the digital give the best power and torque with the same engine .
