2753450 - Introduction - ENGINE

CURRENT DEVELOPMENTS

These engines are fitted with ''Magneti Marelli Common Rail' high pressure electronic injection systems for fast diesel engines totally managed by a Multijet MJD 6JF electronic control unit.

PERFORMANCE

This engine is able to provide the following performance:

  • maximum power 51 kW - 69 BHP EC at 4000 rpm;
  • maximum torque 145 Nm CEE at 1500 rpm.

DEVICES ADOPTED

These engines are fitted with the following emissions control devices:

  • exhaust system with oxidising catalytic converter;
  • E.G.R. exhaust gas recirculation system with heat exchanger;
  • crankcase vapour/gas recirculation system.

STRUCTURE

The unit comprises the engine and all the systems required for its operation:

  • fuel system;
  • air turbocharging system;
  • engine cooling system;
  • exhaust system with catalytic converter;
  • oil vapour recirculation system;
  • E.G.R. exhaust gas recirculation system with heat exchanger;
The operation of these systems is optimized by an electronic control system governed by a control unit. An understanding of the operating logic of the control unit gives an overall picture of the entire GROUP 10 system  Characteristic of working principle 1060  DIESEL FUEL INJECTION.
