Peugeot’s PureTech
Engine of the Year
Peugeot’s Turbo PureTech 3-cylinder petrol engine (110 hp and 130 hp) was named International Engine of the Year in the 1-litre to 1.4-litre category for the 4th year
in a row at the 20th International Engine of the Year Awards.
Groupe PSA has filed 210 patents for its family of 3-cylinder petrol engines.
Launched in 2017 on the new Peugeot 308, the new generation is now being deployed on Groupe PSA’s vehicles across some hundred applications in more than 70 countries. The engines comply with Euro 6d-TEMP and China 6b standards.
Citroen models available with the winning drivetrain include the new C3 hatch and the C4 Cactus.
The PureTech 3-cylinder engine is currently manufactured in France and China.
Production capacity is being doubled in the French plants in 2018, the plants in Tychy, Poland, and Szentgotthárd, Hungary, will also start producing the PureTech engine in 2019 and 2020, respectively.
Powertrain engineering consultancy Drive System Design (DSD) presented a paper detailing a novel technique to improve the thermal modelling of e-machines at the SIA Powertrain Conference in Rouen.
NEXCEL for oil management in
hybrid vehicles
Castrol innovation business NEXCEL has launched a development program to demonstrate the suitability of its active oil management system for new hybrid electric passenger vehicles.
Installation of its system, which enables 90-second spill-free oil changes and ease the used oil re-refinement process, is being carried out by Prodrive Advanced Technologies.
The engineering consultancy is taking NEXCEL’s conversion plans to physically demonstrate the packaging potential in a 2018 Toyota Prius Plug-in, which will showcase the sealed oil cell technology in the first Hybrid Electric application of its kind.
“Powertrain is evolving and the future of the Internal Combustion Engine (ICE) is bright, but active oil management can help further enhance emissions control and public perception of the ICE as part of an innovative hybrid electric vehicle powertrain,” NEXCEL sustainability director, John Ward-Zinski said.
By 2030, leading industry commentators believe that at least 75% of passenger cars will incorporate ICE as a form of motive power, with the majority of those being hybrid electric vehicles.
Hybrid powertrains pose a significant packaging challenge but Prodrive is demonstrating the system’s suitability for series production in current and next-generation vehicles.
The conversion requires room to be created for the sealed cell and dock, which in this project has resulted in the relocation of the Prius’ battery.
The traditional oil sump and filter, for example, will no longer be required so access for regular, routine servicing is no longer a key factor, and alters the requirements for ICE location and packaging. This is a perfect fit for the low maintenance, high efficiency image sought by vehicle manufacturers developing advanced hybrid passenger vehicles
New technique for thermal modelling of e-machines
The paper explained how credible results for heat transfer can be obtained in just one week, by using a combination of particle-based fluid modelling and steady state Finite Element (FE) thermal modelling.
The novel approach, based on the Moving Particle Simulation (MPS) method, is the result of collaboration between Drive System Design and simulation based engineering science consultant, EnginSoft.
It allows design iterations to be compared during the concept stage of a new e-machine, enabling enhanced optimisation for e-machines and integrated EV powertrains.

“It can take as little as a few days using modest computer hardware to simulate several seconds of real time data, compared to weeks if using finite volume CFD,” said Luca Martinelli, Design Engineer. “By combining the performance benefits of MPS with appropriate modelling simplifications, it is possible to use this method as an iterative design tool, rather than just for final validation.”
The paper, jointly authored by DSD and EnginSoft, described the growing importance of optimum e-machine cooling as power density increases and the e-machine is integrated into the powertrain.
