Product Design Group -PD/PV/AM PD-EA R&D Apr 21, 2017 Cummins Internal Use Only

Agenda Highlights of 2016 2017 Focus Support Needed Cummins Internal Use Only

Highlights of 2016 –Class 1 VPI 2) New head design with optimized air intake port, water jacket to improve performance with enhanced ALD 1) Overhead Camshaft and integrated brake system to have higher brake performance 9) Integrate mature Cardinal Fuel system 3) Integrated block/GSH design to make lower weight through ALD 8) Single/Optimized Rear gear train for better NVH 6) Lower CH / Steel Piston, low friction power transfer design to keep higher efficiency/robustness 4) Through joint ALD to optimize liner, head gasket design to improve liner distortion/stress and sealing performance 5) New simplified FEAD to easy cooling package int. 7) New cooling system/jacket design optimization to achieve lowest pressure drop Cummins Confidential

Highlights of 2016 –ALD and ESW Team capability growth, 2 ESW owners /34 ESW specialists development /key systems and components development(Crankshaft/Con-rod and bearing/EAT/IAT/Block and head resource/Gear train/iBrake and Valve train, … ) GT-ValveTrain analysis G13_Crankshaft analysis(AVL Excite) Lower CH Piston with enough structural strength Analysis DOE to optimize head structure (cooling system) Cummins Confidential

2017 PD Team Focus Continue to prioritize resource to support NS6 projects (G13/New ISZ/New B&D&L, ISF series…) Leverage the key tools/processes to improve delivery quality with timely manner (KAF/iDFMEA/CPM/Design Review/VPI, …) Team & peoples development, SME/ESW Owner and Specialists by challenge assignments, tech-sharing and training (TWE/Rotation) Enhance analysis capability development (ALD) in some key areas, bearing, crankshaft, power cylinder, gear and iBrake. NVH analysis and experimental capability development for NS6 projects DVP&R consolidation and optimization by ALD and NUD focus, creatively apply ESWs to fit-for-market verification and validation (sufficient V&V with less resource and as earlier) Improve concept design quality by prioritizing quality resource (specialist involvement) Keep team be safe, safety tour regularly based (Weekly or Bi-weekly) Cummins Confidential

Key Projects of 2017 Dabai (ISF4.5 NS5) -M4 ~M5 (SOP) Scope/requirements change, multi-applications (Truck with PEMs/Bus/Coach/Refrigerator) ISM Block and Head resource for global market -~ M2~ M3 … M5 (SOP) Critical to XCEC and JEP First time to EA R&D, well developed with global involvement and collaborations New ISZ NS6 - ~ M2~ M3 Over 200 new parts, over 15 full HCs design engineers + 10 analysis HCs involvement Optimum Block/Head/Crankshaft/Con-rod & bearing/Gear train/OH Cam with Cap/iBrake/Valve Train, etc. Hanover & RIO (G13 & G12 NS6) - ~ M2~ M3 Upgrade from ISG12, 1) Better performance than ISG12; 2) Mitigate baseline issues Crankshaft and bearing /block, liner deformation, lube/cooling system, etc. New NS6 products, New L/B6/D7 and New F series -M0 ~ M1~ M2 Global technical collaborations (UK, US, Indian, Brazil) Global market (different OEMs and applications) Oncoming projects … Off-highway Tier IV /Marine inland, etc. -in Q3/Q4 VPCR/CR/CPS/JVs & Support … - Common support work Cummins Internal Use Only

Continuous Improvement Productivity Deliver high quality results with timely manner by using limit resource Process & Tool People Keep learning Commitment Responsive Compliance Creative Effectiveness Cummins Internal Use Only

Support Needed More close collaboration between technical function and CE function Work as a team as early as possible (VOC/VPP/TP …) Help to shorten the distance between the development person and the customers & end users Design review involvements Get to know more each other Cross-functional technical sharing Provide training to each other Cummins Internal Use Only
