These days, developing a combustion engine is all about emissions. This means an ignition system should be able to ignite both lean and rich mixtures, as mixtures alternate to make catalyst convertors work. This requires larger gaps between the electrodes of a spark plug, to capture and ignite enough mixture to make it burn. The larger distance requires a higher voltage than used decades ago. Instead of 15.000 Volts, most systems now use 30.000 Volts.
An important demand of emission standards is that the emission levels are not allowed to deteriorate during the lifetime of the car. That means that wear-sensitive components, like breaker points, camshafts and distributer caps, had to be replaced by more reliable, stable systems. Nowadays, a motor management computer controls the low-tension ignition pulses. On most cars, the computer sends timed pulses sequentially to the individual coils, placed directly over the spark plug, thus eliminating the need for a high-tension cable. On other cars, each ignition coil operates two cylinders, firing both spark plugs simultaneously. That is not a problem, as one cylinder is still at the end of its exhaust stroke when the other is ready to fire.
Due to the high voltage of modern ignition systems, the quality of the components is more important than ever. The quality of seals, connectors and wires determines if the car stays trouble free over the years. That's why Nipparts only produces ignition parts that are as good as the products used by the car manufacturers themselves. Nipparts ignition parts are available for all Asian cars.
