Ready to ShipDifferent types of Hitachi ignition systems are as follows:
Conventional Ignition System
The Hitachi conventional ignition system uses a battery, an ignition coil, a distributor, and a set of spark plugs to generate the required high voltage. The system can be called a battery ignition system. It generates a high voltage from the low voltage of the battery. The system uses an ignition coil to step up the battery's 12-volt power to a 45,000-volt output. The coil has two wire windings, a primary and secondary. The 12-volt battery current flows in the primary winding while the secondary supplies high-voltage pulses to the spark plugs. The ignition coil is located between the distributor and the spark plugs. The coil's output is connected to the center terminal of the distributor. The coil generates a spark when the current is cut off suddenly. The distributor routes the high-voltage current from the ignition coil to the correct cylinder at the right time. It uses a rotor arm that spins inside the distributor case, connecting the ignition coil to the individual spark plug terminals through carbon tracks. The distributor also houses the ignition points and a capacitor. The mechanical action of the cam opens the ignition points at a predetermined gap. The capacitor discharges through the points when they open, producing a spark. The condenser improves the spark by stopping arcing between the points. The ignition points, capacitor, and cam are the key mechanical components of the distributor.
Electronic Ignition System
The Hitachi electronic ignition system is a type of ignition system that uses electronic components to control the ignition timing and spark generation. The key components of an electronic ignition system include an ignition coil, an ignition module or control unit, and a distributor with electronic sensors. The ignition coil in the electronic ignition system is similar to that in the conventional system. It converts the low voltage from the battery into a high-voltage signal for the spark plugs. The ignition module or control unit is responsible for controlling the ignition timing based on various engine parameters. It receives signals from sensors, such as the crankshaft or camshaft position, and determines the optimal timing for spark generation. The distributor in an electronic ignition system is equipped with electronic sensors, such as Hall effect or inductive sensors. These sensors detect the position of the rotor or the crankshaft/camshaft and send signals to the ignition module. The ignition module then processes the signals and controls the ignition timing through the ignition coil, ensuring precise timing and reliable spark generation.
Distributor-less Ignition System
The Hitachi distributor-less ignition system is an advanced ignition system that eliminates the need for a distributor. Instead, it uses multiple ignition coils and individual control of the spark plugs. The key components of a distributor-less ignition system include multiple ignition coils, an engine control unit (ECU) or ignition control module, and individual spark plug connections. In a distributor-less ignition system, multiple ignition coils are used, usually two or four coils, depending on the engine configuration. Each coil is responsible for generating sparks for multiple cylinders. The ignition control module receives signals from various sensors, such as the crankshaft and camshaft position sensors, and controls the ignition timing for each cylinder. The module precisely controls the timing of the spark generation based on real-time engine parameters, ensuring optimal combustion and efficiency. The ECU also communicates with other engine management systems, such as fuel injection, to synchronize ignition timing with fuel delivery for improved performance and emissions control.
