Pulse-R Gas Engine #01

Dedicated Gas Engine....why?

LPG, CNG, Bio-gas and even hydrogen are all fuels ideally suited to the Pulse-R concept.
These fuels tend to have a higher effective octane rating than gasoline, they burn slower and have a higher threshold against undesirable pre-ignition and detonation. These uncontrolled ignition phenomena are often referred to as pinking or pinging.

To exploit, for best efficiency, the beneficial octane characteristics of gas fuels an engine needs to run at a higher compression ratio or with some level of supercharged forced induction. In a conventional engine this requires the addition of an expensive compressor or, to achieve high compression, a restrictive inlet and exhaust valve configuration where the valves need to close when the piston is near TDC to prevent contact between piston and valves. This is why all high output diesel engines use superchargers or turbochargers.
Our innovation overcomes these issues on both counts by allowing a free breathing very high compression engine that incorporates an element of 'self-supercharging' by using gas momentum dynamics and reflected pressure pulses to force charge the inlet air.

This is why our prototype Pulse-R gas engine delivers over 35% more torque at 1500-3500 rpm than the market leading direct injection diesel engine upon which it is based.
