Electric, solar-powered, hydrogen, and other alternate fuel vehicles are the wave of the future, but for now most automobiles run on gasoline, which they burn in an internal combustion engine to convert into motion. For combustion to take place, a spark is needed to ignite the fuel mixture in the engine. The vehicle’s ignition system is designed so that a 12-volt battery can generate the very high voltage required to create such a discharge. The heart of this system is a device called an ignition coil.

This ignition coil is a pulse-type transformer. Like other transformers, it consists, in part, of two coils of wire, as shown in the diagram at right. These are both wrapped around the same iron core. Because this is a step-up transformer, the secondary coil has far more turns of wire than the primary coil, which is wrapped around the secondary. In fact, the secondary coil has several thousand turns of thin wire, whereas the primary coil has just a few hundred. In your car, this allows some 40,000 volts of current to be generated by a modest battery.

In a car’s ignition system, direct current (DC) is used (provided by the battery), because the idea is not to create steady, continuous induction, but one single, dramatic induction from a sudden collapse of a magnetic field. As current flows to the primary coil, an increasingly large magnetic field builds up around it as well as around the secondary coil housed inside. When this current is stopped, the field suddenly collapses, and this rapid change induces a surge of current in the secondary coil, which streams out the high voltage Output Terminal and is enough to jump the Spark Gap in the circuit. This spark then ignites the fuel mixture and gets the motor running.

There is just one problem with this scenario. The collapsing field also induces a lesser surge (back EMF) in the primary coil, creating a second, unwanted surge of electricity traveling back through one of the primary terminals toward the switch. To keep that surge from reaching the switch (and creating a damaging spark across those points), a Capacitor is inserted in the circuit. This capacitor – called a condenser in auto ignition systems – safely absorbs the back emf.

Hyper Force System (a.k.a. HFS or X-Power in Japan) is Sun Automobile's new high-efficiency ignition tuning and strengthening system. It focuses on direct ignition engines and is available in 4 and 6 cylinder versions. Check out its ever-expanding Vehicle Application Guide (lower right corner of this table) as we can get you ANY model that is listed in there, including Toyota Prius.

Description:

  1. Benefits:
    • Increased Engine Response
    • Improved Fuel Efficiency
    • Increased Horse Power and Torque
    • Reliable ignition spark throughout the entire rev range
    • Reduced emissions / stabilized idling
  2. Problems associated with ignition coils and the capability of the Hyper Force System:
    • A normal ignition coil inherently generates back electromotive force (*back EMF) during operation. This back EMF negatively affects the ignition device inside the coil, decreases plug voltage, and negatively affects plug efficiency. With this problem, voltage not only becomes unstable but also produces ignition time lag in the next ignition cycle. HYPER FORCE SYSTEM works by absorbing all back EMF, which aids to improve plug voltage and promote complete combustion by producing 100% coil efficiency. Furthermore, HYPER FORCE SYSTEM eliminates any ignition performance loss due to decreased electrical current under heavy throttle.
    • Since ignition efficiency over the entire rev range improves, available torque and acceleration response improves; this efficiency enhancement also contributes to better fuel efficiency and a reduction of harmful emissions.
  3. Included Components:
      Main Unit(1), Mounting Bracket(Set), Zip Ties(3), Double-sided Tape(1)
  4. Specifications:
    • Simple connection between ignition coil and stock harness with a vehicle-specific harness adapter (sold separately).
    • Mounting brackets, double sided tape, and all other necessary hardware included for a direct fit to your vehicle.
    • Intermittent LED on unit to signal operating status.
  5. Coil Image Figure (Reference)
      The 12V voltage which flows from the primary coil is boosted to approximately 15,000 - 20,000 volts at the secondary coil, and then ignites the plug. Since the electrical energy of the secondary coil is directly influenced by the energy of the primary coil, maintaining a stable supply of electric power to the primary coil is ideal.

      Transistor: The switch that receives the signal of ignition from the ECU. Adjusting to ignition timing, it turns ON/OFF.
      D1(Diode): The one-way circuit that prevents the transistor from being damaged by back electromotive force.
