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 .

 



more more atomic!

hey! more new items from san jose moped parts entrepreneurs, atomic. see these new spark plug wires n boots. vintage cloth covered wires in a rainbow of colors! black wires! clear wires!! non-resistor type, read all about it below. + the shielded wires are back too!

atomic non-resistor spark plug wire.

the basic function of a spark plug wire is to conduct spark energy from the ignition source to the spark plugs. the more efficient the wire, the more spark energy is transferred to the spark plug. removing the resistance increases potential ignition coil output, increasing combustion efficiency that is often realized as quicker starts, smoother idle, better throttle response and greater fuel economy. also, a spark plug with a brilliant spark will foul less often.

non-resistor spark plug wires are perfect for contact point ignition systems. most spark plug boots have a built in resistor and a screw type connection where corrosion will occur. all these points are possible places for failure. atomic non-resistor spark plug wires have a clear path, sending the juice from the coil straight to your spark plug, creating a stronger spark.

misconceptions:

“hey, I heard too hot a spark burns holes in pistons?” – not true. ¬†improper fuel mixture and/or incorrect ignition timing can cause this, not a strong spark. by assuring a good spark reaches the cylinder, a proper burn of the fuel mixture can take place. the longer the spark is present, the larger the portion of the swirling mixture is ignited which allows more complete combustion. this inevitably gives you the most from the fuel entering the engine.

atomic shielded non-resistor spark plug wire

shielded non-resistor spark plug wires offer the strongest possible spark. resistive technology is used to reduce RFI-related malfunctions. CDI boxes are mounted close to the ignition coils, and therefore need RFI protection. shielding the ignition wire contains the electrical field within the shielding, thereby eliminating RFI interference and also creating an intense spark. for CDI ignition systems, use a resistor spark plug along with this wire to reduce electrical “backlash”, which may cause interfere with the CDI. this will keep your CDI happy while maintaining the strongest possible spark. contact point ignition systems do not require, and will perform best using this shielded non-resistor spark plug wire without a resistor spark plug. a plug with a brilliant spark will foul less often.
