Current History

Weslake have recently developed an Opposed Piston Uniflow powertrain that can operate on low fire risk bio and heavy fuels. It has excellent fuel efficiency and a good power to weight ratio.​
The engine has immediate applications in both Marine and Aerospace propulsion, also future applications as a range extender Auxiliary Power Unit for Urban Air Mobility also lightweight portable generators and pumps for disaster relief.​
Due to the limitation of battery storage capacity, electrification for marine and aerospace applications are limited. There is a very strong market requirement for ‘heavy oil’ fueled marine and aviation propulsion for the foreseeable future.​
