Lubrication Science and Engineering for Low-Carbon Engines

The transition to low-carbon transport demands innovative engineering solutions to enable sustainable powertrains. A full scholarship is available in the Faculty of Engineering and Physical Sciences, supported by BP Castrol and UKRI/EPSRC. The scholarship is open to UK applicants with a background in engineering or physical sciences and covers fees and maintenance. <br /> <br /> This fully funded PhD project combines fundamental tribology, lubricant chemistry, and real world engine engineering. The successful candidate will experimentally evaluate how alternative fuels interact with lubricants and engine surfaces and study their effects on friction and wear. The project will have access to state of the art experimental facilities and advanced surface and chemical characterisation techniques. Through close collaboration with BP Castrol, the PhD will deliver insights that directly support the design of durable, efficient, and sustainable engine lubrication technologies.<br /> <br /> This project is ideal for highly motivated graduates seeking a PhD that blends cutting edge research, hands on engineering experimentation and strong industrial engagement, while developing skills highly sought after in academia and advanced engineering industries.<br /> <br /> The project will be based across two Schools in the Faculty of Engineering and Physical Sciences: Mechanical Engineering and Chemical and Process Engineering.

<p>Low-carbon fuels such as methanol and ammonia are increasingly considered viable options for decarbonising internal combustion engines, particularly in large marine and heavy-duty applications. However, their adoption introduces new and largely unexplored challenges for engine lubrication systems, arising from fuel–lubricant interactions, contamination effects, and altered tribochemical processes. Lubricant degradation in the presence of these fuels can compromise frictional performance, accelerate wear of critical engine components, and reduce engine reliability and efficiency, posing risks to the durability and cost-effectiveness of future sustainable transport technologies.</p> <p>Methanol and ammonia can enter the lubrication systems through fuel dilution, blow-by gases, or incomplete combustion. Their presence induces chemical degradation of base oils and additives and promotes tribo-corrosion of steel surfaces. This project aims to study the effects of methanol- and ammonia-contaminated lubricants on the tribological performance of engine components. Through systematic experimental and analytical research, the project aims to develop a mechanistic model that links lubricant chemistry, fuel contamination, and tribofilm properties with friction performance and surface wear. <br /> Key objectives are:</p> <ul> <li>To experimentally assess the impact of methanol and ammonia contamination on lubricant degradation and tribological performance under representative engine conditions.</li> <li>To characterise the physical and chemical structure of tribofilms formed from contaminated lubricants to identify the friction and wear mechanisms. </li> <li>To formulate and evaluate lubricant additive strategies, in collaboration with Castrol, tailored for engines operating on methanol and ammonia fuels. </li> </ul> <p>The project includes opportunities for collaboration and industrial secondments with BP-Castrol.</p> <p>Further information about research within the School of Mechanical Engineering and the School of Chemical & Process Engineering can be found here:</p> <ul> <li><a href="https://eps.leeds.ac.uk/mechanical-engineering-research-degrees">School of Mechanical Engineering Research</a> </li> <li><a href="https://eps.leeds.ac.uk/mechanical-engineering-research-functional-surfaces">Institute of Functional Surfaces (iFS)</a> </li> <li><a href="https://eps.leeds.ac.uk/chemical-engineering-sustainable-systems-processes/doc/clean-combustion/page/4">School of Chemistry and Process Engineering</a> </li> </ul> <p style="margin-bottom:11px"><strong>Selection Process</strong></p> <ul> <li>All applications will be considered after the deadline.
