Transient Plasma Systems has developed a nano-pulse plasma ignition system for the fuel-air mixture inside the cylinder, which can improve engine efficiency by 10-20%..
In a conventional four-stroke gasoline internal combustion engine, the blow is generated by a spark plug that ignites the air / fuel mixture. Although this spark lasts for a few milliseconds, and the control process is now electronically controlled rather than mechanically controlled, the principle remains the same as in 1910 when Cadillac added it to its engines.
Pulse energy technology company TPS is working to commercialize new solutions for civilian vehicles. The developers propose to completely abandon the existing concept and ignite the combustible mixture inside the internal combustion engine cylinder using plasma pulses lasting several nanoseconds.
HOW IT WORKS: Internal Combustion Engine
They have a much higher peak power than a conventional spark, but because of their short duration, the ignition actually is quite low energy. This allows for better and more stable fuel combustion at a high compression ratio. and lower temperatures, therefore, improving the efficiency of the engine, which produces less nitric oxide.
The TPS developers say that the use of the new system can increase the thermal efficiency of the internal combustion engine by 20%, and in the most efficient options today, such as at Toyota Prius (with an efficiency factor of about 41%), by 10% to 45% – the level of ignition systems of Formula 1 engines. The technology is fully compatible with various types of equipment, so engineers do not need to change the design to use it.
The company plans to work directly with leading car manufacturers. The cost of the new system has not yet been disclosed, but TPS officials say the benefits of fuel savings will outweigh the additional costs and will delight both suppliers and users..
Cars are now rapidly changing and will change more in the next decade than in the last century.
