FRANKFURT, - "results for saving of 10 % obtained through tests on a system of direct injection gasoline engine equipped with a turbocharger," said Mixell. Added, when this Federal-Mogul continues to develop the ACIS for coil engine with plug-ins or coil directly over the spark plug.
Spark plug developed by Federal-Mogul is - one of the largest automotive component manufacturers in the world - very interesting. Look at the picture, is very different than with conventional spark plugs are in use today. Design or construction of the electrodes like a star. The result, sparks produced is also different, spreads in all directions.
Federal-Mogul as an inventor - is still being developed - called the spark plug with ACIS, stands for Advanced Corona Ignition System. Yes, the ignition system of a sophisticated ring, or corona.
More and Save Money
Spark plugs which had been exhibited at the 2011 Frankfurt Motor Show, is claimed could radically alter the performance of the engine, ie fuel consumption becomes more efficient 10 percent. "Enhancement of that size is not obtainable by conventional spark plug," explained President and CEO, Federal-Mogul, Jose Maria Alapont about the greatness of ACIS.
Described, the conventional spark plug works with memercikan sparks (to burn a mixture of air and fuel that has been compressed) from a single point. After that, the burning of pushing the piston travels down to the point of death (TMB) in step effort.
In ACIS, ciptratan sparks generated greater. Because sparks occur around the peak of the spark plug electrodes to form a ring. The result, ionization or combustion takes place more quickly and efficiently.
Amazingly, directly occur on a broader scope. Consequently the next, with "plasma" is extremely high, air and fuel mixture will be more easily burned. In fact, the combustion process with a mixture of Miski can be done more easily, including exhaust gas re-burn recycled (EGR).
Fast and Steady
Sparks in the form of corona or ring occurred within ACIS faster (shorter) but steady. According Kristapher Mixell, Powertrain Energy Director of Federal-Mogul, a conventional spark plugs it took two or three milliseconds to produce a spark while the ACIS only about 100-200 microseconds.
Ring of sparks could be designed, for example, had a diameter of 30 or 40 mm. With this addition, the combustion can be initiated throughout the combustion chamber. "This opens up new possibilities, the shape of the combustion chamber so more efficiently," continued Mixell.
Prevent Detonation
ACIS is also claimed to reduce detonation, ie a mixture of symptoms due to the temperature of burning their own fuel and air mixture of high (up) when compressed.
Detonation occurred before ignition. These symptoms occur because of the pressure waves from two separate sources of combustion, and detonation is triggered by a sparkplug pembakran. When both combustion "collision" appears a loud explosion.
In ACIS, it can be prevented because sparks occurred very rapidly and within the scope of a large room. Pembakran can be controlled.
High Compression
It is said, ACIS allows the compression ratio is made higher. Eg 14:1 on the engines without a turbocharger. As for the engine with the turbo, can be 12:1. Because the system is able to prevent the occurrence of detonation. With inipula, erosion of the electrodes can be reduced a result, the spark plug service life is also longer.
