As regards the company and its products:

• Overview of CAP background and activities. CAP provides both retrofit systems to customers directly as well as works with OEMs.
• Retrofit system is called ‘Genesis’: average gas substitution is ~50-60%
• OEM Dual-Fuel system interacts with the engine management software. Average gas substitution is ~70-90%
• Motivation principally is economics and providing ~30% fuel savings to customer (0.15 pence per mile in the UK case)

As regards the company position in relation to the future UN regulatory framework:

• Need for a UN Regulation: Lack of regulations leads to uncertainty that is usually exploited by unethical and un-regulated companies. Without a regulation quality control also can be a problem
• Retrofit HDDF should be considered within R115 with fair and logical test protocols and limits;
• Which Euro classes?: The interest will tend to focus on Euro III to Euro V diesel vehicles;
• Which HDDF types?: Retrofit HDDF will be type 1b and, in the majority of the cases, 2b; Type 1a and 3 make no economic sense;
• Emission limits: For regulated emissions the original limits can be applied, for GHG’s the mother engine can be used as reference;
• Test protocol: it should be kept to the steady-state 13-mode ESC/WHSC. Retrofit system suppliers generally cannot afford the level of complexity necessary to develop systems for the ETC/WHTC;
• In general, D-F not part of the UK policy framework for carbon reduction;
• ‘Light touch’ regulatory approach ‘appreciated’.
