These represent the new generation of small spark ignition system. The systems are unique, revolutionary, extremely small and light, using electronic capacity discharge method for spark generation. The system can be used for engines from 0.9 (1.5cc) and upwards, 1 or 2 cylinders, two or fourstroke engines, even for motor cycle and car engines. in the case of a 4 cylinder engine a second spark ignition system is added or a distributor for multicylinder engines is used.
The Runtronic spark ignition system is provided with an electronic advance and retard circuit for rpm
controlled ignition timing. The system generates three sparks in two degrees of crankshaft rotation up to
4000rpm and then single spark thereafter which makes the engine easy to hand start. The engine will not
kick-back, since the ignition point is automatically retarded at start.
No mechanical advance and retard device is needed. Total advance and retard range is up to 30 degrees stepless variable.
Current drain is very low
-at rest 15mA, 5V supply
-at 12,000 rpm 260mA, 5V supply
The very low standby current will not drain batteries if left on by mistake.
- more than 60,000
By converting larger gasoline engines, equipped with magneto ignition systems, you can obtain:
- a smooth running engine
- higher top end rpm
- lower and more reliable idling
- easier hand starting
- considerable weight saving
Runtronic spark ignition systems have been designed to be extremely rugged and vibration proof. The electronics unit has a built-in sparkcoil for single or dual output. The unit is fully encapsulated (potted).
The power and the sensor leads are connected to a special connection PC board, mounted to metal studs in the electronic unit by means of 3 screws. Those mounting screws also serve as connectors to the circuits in the electronic unit. The spark plug cap and the spark plug cable are screened for minimum interference. Screened sparkplug caps for standard size sparkplugs are available.
Changing the Runtronic system to dual output is easily done without any soldering.
The Runtronic ignition system, using 2.4 - 4.8V power, gives sufficent spark energy for engines with a 1/4" - 32 or 10 - 14mm spark plug. The power supply can be either dry cells or nickel metal hydride. The total weight, including power supply, can be as low as 75-85 grams(2.602 oz). The power supply is connected by means of a regular 3 pin ON /OFF receiver type switch harness. Normal power supply is 5V (nicad) but the system will accept any supply voltage between 2.5 - 6V. All Runtronic systems are provided with reverse polarity protection.
