Description - DIESEL ENGINES ELECTRONIC MANAGEMENT - Fiat DOBLO 1.9 JTD 8V da 12/03
An electronic management system supervises and governs all engine parameters. It optimises performance and fuel consumption by responding in real time to different service conditions.The Diesel engine is fitted with a COMMON RAIL UNIJET injection system. This uses high injection pressure controlled electronically. Fuel delivery, termed a pilot injection, is optimised by the electronic control unit via the injector and not managed by the pump.
Functional description - DIESEL ENGINES ELECTRONIC MANAGEMENT - Fiat DOBLO 1.9 JTD 8V da 12/03
Engine control unit M10 monitors and controls the electronic injection system. The supply for the engine control unit M10 is controlled by the ignition (15/54) at pin 58 by the line protected by fuse F16 of the engine compartment junction unit B01 .
