Libertine FPE

What if the world’s cheapest engine was the cleanest?

Libertine FPE is a low cost power source that uses proven technologies and low cost manufacturing methods to deliver unrivalled efficiency, cost and reliability.

This changes everything.

Libertine FPE allows small renewable power producers to create more power and waste less heat

Libertine FPE is a sub 100kWe generator that can deliver around 50% electrical efficiency, offering scale generator economics at smaller biogas sites. The engine can optimise its compression ratio and valve timing according to the feed biogas methane composition, and runs an over-expansion cycle which further enhances efficiency whilst making the engine very quiet.

Libertine FPE provides lightweight, mobile power for consumer, industrial and other applications

Libertine FPE is a simple, reliable and portable power generator that can be scaled from 10kWe down to a 1kWe device around the size of a shoebox. A 2kWe Libertine FPE generator could fit into a backpack, weigh less than 15Kg and run at full load for four hours a day for a week on just 10Kg of diesel fuel. This format is considerably quieter than conventional generator technology due to the engine’s over-expanded exhaust stroke.

Libertine FPE will reduce the cost of low emission vehicles in developed and emerging markets

Libertine FPE is a low cost, modular automotive engine for range extended electric vehicles and low cost hybrids. Its combustion cycle and unique scavenging geometry make this an exceptionally clean engine with very low levels of tailpipe emissions. In its flex-fuel variant, the compression ratio is continuously optimised for hydrous ethanol, gasoline or anything in between, converting ethanol’s higher octane rating into increased power and efficiency.
