The main objective of WP1 is to set a frame for the overall project, in terms of fuel consumption and pollutants emissions targets, technical developments needed to reach them, and performance assessment. To achieve this goal, the five sub-objectives are as follows:

• Update and confirm development targets in terms of fuel consumption and emissions.
• Define representative use cases and KPIs for evaluating hybrid strategy and RDE.
• Define generic hybrid strategy.
• Define raw engine-out emissions limit and requirements for after-treatment system.
• Final assessment of emissions performance under considerations of RDE.

The first objective of WP2 is to develop a gasoline diluted engine concept achieving a maximal brake thermal efficiency of 47% and an optimised trade-off between efficiency and pollutant emissions in real driving conditions according to KPIs defined in WP1. All the main features of this engine will be optimized: dual dilution approach (air and EGR) and turbocharging,
innovative charge motion, ignition, injection, valvetrain. The second objective is to procure all the parts necessary to build up the engine and to proceed with a motored break-in phase before delivering the engine to WP4.

The goal of WP3 is twofold. It will develop a full exhaust after-treatment system (EATS) to demonstrate a real-world environmental impact by complying with pollutant emissions levels defined for the European Commission Horizon Prize for cleanest engine of the future and those anticipated for the Euro 7 regulations. The after-treatment system will be designed to suit the project’s gasoline lean burn hybrid application. To achieve this, it must work at stoichiometric conditions, particularly for cold start and hybrid stop/start operations. It must deliver NOx conversion in lean conditions and achieve good non-regulated gaseous and PN down to 10 nm. At the outset of the project function, components, volume, layout and sensors of the exhaust after-treatment system will be developed. Also, a waste heat recovery system (WHRS) will be developed and manufactured to contribute to fuel consumption and pollutants emission reduction. Two devices will be investigated: (i) the exhaust heat recovery system (EHRS) whose function is the engine and cabin fast warm-up through the heat transfer from exhaust gas to engine cooling circuit, and (ii) the thermoelectric generator (TEG) that provides both engine fast warm-up through the heat transfer from exhaust gas to engine cooling circuit and electric energy generation for the auxiliaries. The most suitable and advantageous system will be installed on-board for vehicle demonstrator.

The first objective of WP4 is to develop the engine and after-treatment control functions to manage the new technologies identified in WP2 and WP3. The second objective is to evaluate the multi-cylinder engine performance in terms of efficiency and pollutant emissions after a first optimisation of the settings in steady state conditions. The target is to achieve 47% maximal brake thermal efficiency and to demonstrate engine-out emissions suitable with respect to the Grant Agreement No. 101006841 12 expected tailpipe emissions thresholds as defined in the European Commission Horizon Prize for cleanest engine of the future. Control functionalities will be developed for the Dual Diluted Combustion Approach engine (air and EGR), as well as for high pressure injection, ignition, valve-train, electrified turbocharging and EATS. The control functional validation will be performed at the test bench, before proceeding with the pre-calibration and the thermodynamic assessment in steady-state conditions.

The objectives of WP5 are, first of all, the integration of ICE & AFT, and their installation into the vehicle demonstrator for the fine-tuning calibration, then the energy management related through SW integration and calibration, and finally the HVEC HW & SW adaptation for the drivetrain. This WP will lead to the final Engine Controls calibration by performing the optimised representative worst case RDE in chassis dyno, driving additional RDE cycles and eventually performing climatic chambers tests. The same vehicle will be later released with the corresponding calibration for independent testing.

The overall objective of WP 6 is to foster communication and dissemination of the results of the PHOENICE project. Activities are continuously carried out during the project. The following issues will be addressed:

• To validate a master plan for the dissemination of project results to be used during the project.
• To perform the dissemination tasks according to the Communication and Dissemination Master Plan (CDMP).
• To deliver a data management plan (DMP).
• To participate and coordinate activities with other similar H2020 projects as well as relevant networks at European level.
• To update the market analysis and the regulatory and standardisation framework in view of defining a tailored business plan for every partner.

The objectives of WP7 are to:

• Ensure overall coordination and communication and timely fulfilment of contractual obligation towards the European Commission (including to receive and to distribute EC funding).
• Follow up on the state of PHOENICE deliverables, milestones, and reports achievements.
• Take care of financial, budget, time planning, and grant agreement matters.
• Promote and follow up PHOENICE internal communication.
• Review the quality of the project deliverables.
• Validate that the objectives and tasks are fulfilled in a timely and cost-effective way.
• Assist all partners in the realisation of their contractual commitments.
