According to it, "instead of looking only at tailpipe emissions, we need to conduct a full life cycle assessment of such solutions if we really want them to be sustainable. Doing otherwise is irresponsible and sooner rather than later reality will catch up," said the blogThe firm says that an e-REX equivalent to a traditional 2000cc engine weighs just 77 lbs .
This is made possible by an opposed-piston design with four pistons on each side for eight. The opposing pistons share a combustion chamber and are held together by fixed rods. These rods press on plates with an oscillating wave-like shape, allowing the rods to push and release the pistons in a smooth, synchronized action.
The engineering on e-REX also makes sure that the users are greeted with a smooth running motor as "moving parts do so reciprocally and in equilibrium at all times in all 3 planes, canceling out one another."applications that would combine the economy and low emissions of a cutting-edge four-stroke engine with the simplicity, versatility, and power of a two-stroke engine.
The team is "currently working with the CMT of the University of Valencia to develop the e-REX to satisfy EU7 European emissions standards when they are implemented in 2025." The team is also looking to make the e-REX the perfect greenIts size, weight, power capacity, and lack of vibration also make it ideal for powering both light/medium aircraft/drones or as an APU in bigger aircraft, eliminating the need for an additional turbine.
