The outstanding quality of this system are obvious. Not so much increased the service 'side of the electrode' (in practice it does not burn), and and also the central electrode and the insulator could be made more durable. Not allowed to introduce such a system ignition problems with supply and distribution of electric charge. The next step was improving geometry, lateral and central electrode spark a simple system. If caught in any directory as an example of large companies, then it is possible to find any methods to improve 10-20 spark formation. Form the central electrode and the most radical change example of this model is probably Rapidfire firm Delphi. On the surface of its central rod made of ribs 12 with sharp edges.
On the edges of such a candle descends at least easier than with conventional smooth cylindrical surface of the central electrode. This allows, on the one hand, the lower the threshold of ignition, and on the other – to make it safer and more stable when idling or starting. Vendors Car notice that it is the most dangerous of these regimes in the perception of the likely customers of all cars. Rapidfire Manufacturers estimate that its system compared to the 'factory' spark auto permits by 18% to increase the response reaction accelerator, a 27% stability of idling and a 2% fuel savings, but for what it's anything out there (they) Ford or Chevrolet. No one measured the improvements in the engine car of the average Russian.
