Building an engine that is truly sustainable.
E2 is developing a pressure-pulse impulse turbine architecture for high-power mobility, using controlled gas pulses to generate shaft power without a conventional piston engine layout.
Make heavy mobility sustainable without sacrificing power.
We are building a compact pressure-pulse engine platform for sectors where range, payload, duty cycle and infrastructure make simple electrification difficult.
A new combustion-to-shaft architecture.
Instead of using combustion pressure to drive pistons, E2 directs short-duration pressure pulses onto an impulse rotor. The goal is a smaller, mechanically direct, fuel-flexible power system for high-duty-cycle applications.
Long-term design target relative to legacy combustion architectures, subject to prototype validation.
Compact pistonless architecture designed around rotor power extraction and fewer reciprocating parts.
A fuel-flexible engine that can cater to future fuels for a sustainable future without the need for expensive retrofitting.
Propane-air testing
Validate combustion-driven pressure pulses and thermal loading in a controlled prototype.
Hydrogen pathway
Develop clean-fuel compatibility after the core mechanical architecture is measured.
Engine integration
To perform and validate the complete engine architecture working in heavy-duty vehicle duty cycles.
