L? VEHICLE INJECTION SYSTEM FOR MOTOR VEHICLES? IS IT ESSENTIAL FOR THE NEW EMISSION CEILINGS TO BE REACHED AND FOR THIS TO BE DEVELOPED AS FUEL INJECTORS WITH ALWAYS IP PERFORMANCE? HIGH AS A CONSEQUENCE, ARE THE CURRENT PRODUCTION PROCESSES RELATED TO THE GENERATION OF THE SPRAY AND THE CURRENT SYSTEM OF THE CHARACTERISATION OF THE PERFORMANCE OF THE INJECTORS, NOT PI, AN INNOVATION? SUFFICIENTLY ACCURATE TO ACHIEVE AND MEASURE THE KEY CHARACTERISTICS INFLUENCING THE EMISSIONS. QUALITY? SPRAYS? IS IT CLOSELY LINKED TO THE DRILLING OF THE SITES AND THE CURRENT TECHNOLOGY OF ELECTRODISCHARGE? SHOULD I BE REPLACED BY A PROCESS TO PI? HIGH PRECISION AND FLESISITILIT?: LASER DRILLING. IS IT ALSO NECESSARY TO REMOVE THE LIMITS OF THE CURRENT MEASUREMENT SYSTEMS? FLUID SUPPLIED AND JET CHARACTERISATION THROUGH THE DEVELOPMENT OF INNOVATIVE HIGH-AUTOMATION SYSTEMS THAT CAN APPRECIATE TODAY NON-MEASURABLE PHYSICAL PHENOMENA. AND? THEREFORE REQUIRED
