Citroen: Bosch HDI EDC 15 C2 Injection System and Particle Filter PDF.
The aim of this brochure is to define the composition and operation of a BOSCH EDC 15 C2 HDI diesel engine management system, combined with a particle filter system, in relation to the DW12 Diesel engine.This device consists of an ECU which analyses the information from the various sensors, and then operates the injectors at the correct moment. It also controls a pressure regulator, the exhaust gas recycling electrovalve and the turbocharging pressure modulating electrovalve.
The following subjects are dealt with in this document:
General details and system presentation,
Description and operation of the components of the various functions, or the functions themselves,
Description of the operating phases:
– of the injection system,
– of the particle filter system.
Notes on maintenance,
The electrical circuit.
