Toyota R&D team improves free piston linear generators

Unlike a traditional ICE, which propels a drive shaft, a free piston engine linear generator (FPEG) is designed to generate electricity directly. Magnets attached to the piston move within a linear coil, converting kinetic energy to electrical energy. A team from Toyota Central R&D Labs presented a prototype FPEG to the SAE in 2014. Now… Read more »

UK startup improves free piston linear technology, generating power with no drive shaft

A free piston linear power generator (FPEG), which uses combustion to generate electricity directly, using no drive shaft, could provide an EV range extender that’s far smaller and more efficient than a legacy ICE. Several research groups, including a Toyota R&D team, are investigating this intriguing technology. UK startup Libertine LPE has developed an FPEG… Read more »

Toyota developing free-piston engine linear generator for electric drive vehicles

A team at Toyota Central R&D Labs is developing a prototype Free Piston Engine Linear Generator (FPEG), which they described at the recent SAE 2014 World Congress in Detroit. Unlike a traditional ICE, which propels a drive shaft, the FPEG is designed to generate electricity directly. It consists of a two-stroke combustion chamber, a linear… Read more »
