PTL carried out concept studies for in-wheel motor architecture and supported broader electrical systems development for electric-drive applications. The work required consideration of packaging, electromagnetics, thermal management and control electronics from the start rather than optimisation in isolation.
PTL has developed a selection of hydraulically controlled variable valve actuation systems, including fast-acting valvetrains, combining dynamic modelling, rig-based validation and specialist component development. The work supports advanced engine programmes where standard valve mechanisms cannot deliver the required flexibility or control authority.
PTL supported the design, software development, procurement and testing of a screw pump system for multiphase fluid applications in high-temperature, high-pressure down-well environments. These are conditions where conventional assumptions and standard testing approaches are often no longer valid.
PTL led the design of the drivetrain and cranktrain of a 75 kW thermal-output industrial heat pump, where the drivetrain operates within a pressurised helium environment. This application required novel engineering solutions well outside conventional reciprocating machinery approaches.
PTL supported the development of an ultra-high-pressure diesel injection system using a multi-domain approach combining hydro-mechanical system modelling, CFD, FEA and rig testing.
PTL carried out a thermal assessment of an experimental diesel injector concept in which the specific geometry exposed a much larger surface area to combustion gases than a conventional design. That exposure created an inherent heat management risk that needed to be quantified before the concept could progress.
PTL supported Southwest Research Institute (SwRI) in developing a range of single-cylinder engine (SCE) research platforms, covering both light/medium-duty and heavy-duty applications. These have been used for internal research and development, consortium projects, and third-party customers programmes, including gasoline, diesel and Hydrogen.
PTL supported Southwest Research Institute in developing a dynamic bearing test rig capable of recreating crankshaft bearing loads on a crank-angle basis, generating the fast-changing, high-magnitude load profiles needed for credible bearing and lubrication validation.
PTL led an eBike development programme built around proprietary CVT technology. The core challenge was not whether the hardware could be made to function, but whether it could be made to feel natural, with a consistent pedalling response across different riders, riding styles and terrain conditions.
PTL carried out an evaluation of a vehicle cooling-system to help a customer understand how the circuit and subcomponents were behaving, identify where the deficiencies sat, and to determine which changes would make a practical difference.
