The H-engine—basically two separate engines housed within the same engine block—comprises two switchable parallel piston banks, independently fueled by gasoline and CNG. Startup Eco-Motive has developed what it calls the first dual-fuel “H” engine; it recently received a patent (# 8807098 ) on the design.

UK-based Libertine FPE has built a demonstration prototype of its linear electrical machine for what it is calling “Digital Piston Motion Control” in free piston engine applications. This technology will allow researchers to develop future combustion engines free from the piston motion constraints dictated by the crankshaft.
