HyPACE – Hybrid Petrol Advanced Combustion Engine – Advanced Boosting System for Extended Stoichiometric Operation and Improved Dynamic Response 2019-01-0325

The HyPACE (Hybrid Petrol Advanced Combustion Engine) project is a part UK government funded research project established to develop a high thermal efficiency petrol engine optimised for hybrid vehicle applications. The project combines the capabilities of a number of partners (Jaguar Land Rover, Borg Warner, MAHLE Powertrain, Johnson Matthey, Cambustion and Oxford University) with the target of achieving a 10% vehicle fuel consumption reduction, whilst still achieving a 90 to 100 kW/litre power rating through the novel application of a combination of new technologies. The donor engine for the project was Jaguar Land Rover’s new Ingenium 4-cylinder petrol engine which includes an advanced continuously variable intake valve actuation mechanism. The new HyPACE boosting system utilises a Borg Warner 48V eTurbo™ featuring a variable geometry turbine which enables the capability to both provide electrical assistance, to improve dynamic response when required, as well as being able to utilise waste exhaust gas energy to generate electricity. This paper presents results from a testing programme which demonstrates the capability of the new boosting system to extend the stoichiometric operation of the engine. Results showing the improvement in dynamic response achievable with the 48V eTurbo™ are also presented, as well as results which characterise the capability to generate electricity through the recovery of waste exhaust gas energy using this system.
