This plasma ignition system can increase engine efficiency by 20%
In 2019, we took a look at an interesting new advanced ignition system from Transient Plasma Systems. It replaces the conventional spark plugs in a vehicle's engine with an ignition module that uses very short duration (nanosecond) pulses of plasma to ignite the fuel/air mixture within the cylinder.
