Powertrain Systems for a Sustainable Future Conference 2023
About the Conference
The Powertrain Systems for a Sustainable Future Conference will provide a key forum for all vehicle, engine and powertrain development engineers and researchers to share their work and learn about the latest development and technological trends taking place.
The conference is organised and managed by the Institution of Mechanical Engineers. The conference runs 29 November 2023 - 30 November 2023. Ricardo's Dr Richard Osborne will be presenting a paper on the Development of a Direct-Injection Heavy-Duty Hydrogen Engine on 30 November.
Hydrogen-fuelled internal combustion engines (ICEs) offer a zero-carbon fuel option for many applications. As part of the global effort to study hydrogen ICEs Ricardo has developed single-cylinder and multi-cylinder heavy-duty engines.
The engines are representative of a 13 litre Euro VI heavy-duty production application converted to run on hydrogen fuel with limited changes. The engine is fitted with direct hydrogen injectors which enable flexible injection strategies and reduce hydrogen in the intake system. Steady-state testing was carried out over an array of speed and load points covering a typical heavy-duty drive-cycle area.
Engine test results are presented and analysed in this paper. The combustion system can run to values exceeding lambda 5 and 40% exhaust gas recirculation (EGR) can be tolerated. The impact of lambda, EGR, injection and ignition timing variations are presented and demonstrate how the system responds to the corresponding changes in specific heat capacity, mixture preparation, and combustion phasing.
Ricardo's Dr Richard Osborne will be presenting this paper on 30 November 2023 14:50 GMT. Click here to book tickets.
