Abstract
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 that is optimized for hybrid vehicle applications. The project combines the capabilities of a number of partners (Jaguar Land Rover, BorgWarner, 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/liter power rating through the novel application of a combination of new technologies. The baseline 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. A concept study has been undertaken and detailed combustion Computational Fluid Dynamics (CFD) models have been developed to enable the optimization of the combustion system layout of the engine. Gas-dynamic simulations have been used to configure the revised high and low pressure Exhaust Gas Recirculation (EGR) circuits and the new boosting system, both provided by BorgWarner. The HyPACE boosting system utilizes a BorgWarner 48V eTurbo™, featuring a high temperature capability Variable Geometry Turbine (VGT), which enables the ability to both provide electrical assistance, to improve dynamic response when required, as well as being able to utilize excess 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 characterize the capability to generate electricity through the recovery of waste exhaust gas energy using this system.
