  "text": "The in-service family may be defined by basic design parameters which shall be common to vehicles within the family. Accordingly, vehicle types may be considered as belonging to the same in-service family if they have in common, or within the stated tolerances, the following parameters:\n2.4.1. combustion process (two stroke, four stroke, rotary);\n2.4.2. number of cylinders;\n2.4.3. configuration of the cylinder block (in-line, V, radial, horizontally opposed, other. The inclination or orientation of the cylinders is not a criteria);\n2.4.4. method of engine fuelling (e.g. indirect or direct injection);\n2.4.5. type of cooling system (air, water, oil);\n2.4.6. method of aspiration (naturally aspirated, pressure charged);\n2.4.7. fuel for which the engine is designed (petrol, diesel, NG, LPG, etc.). Bi fuelled vehicles may be grouped with dedicated fuel vehicles providing one of the fuels is common;\n2.4.8. type of catalytic converter (three-way catalyst, lean NO x trap, SCR, lean NO x catalyst or other(s));\n2.4.9. type of particulate trap (with or without);\n2.4.10. exhaust gas recirculation (with or without, cooled or non-cooled); and\n2.4.11. engine cylinder capacity of the largest engine within the family minus 30 %.",
