Enerpulse believes that the Grail engine design will be a paradigm shift in how future vehicles use spark ignited fuel. As such we have partnered with Grail Engine Technologies in their effort to reduce our dependence on foreign oil while at the same time reducing greenhouse gasses. We congradulate the Grail team and recognize the significance of their efforts.

Grail Engine Technologies is able to accomplish a level of combustion with Pulstar plugs that no spark plug can match.

The difference is the internal capacitor (pulse circuit).

Pulse plugs may look similar to spark plugs on the outside, but inside the technological advances of Pulstar are evident. Pulse plugs feature a unique capacitor-based circuit that captures energy normally wasted by spark plugs and generates a spark with 10 times greater energy than any spark plug.s
