125000242 - INTRODUCTION - ENGINE

SPECIFICATIONS

TYPE

Current developments

These engines are fitte with ''''Bosch Common Rail EDC-16C8 high pressure electronic injection systems for fast diesel engines totally managed by an electronic control unit.

SPECIFIC FEATURES OF THE SYSTEM

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.

COMPOSITION

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;
• anti-shake switch-off system.

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 INJECTION SYSTEM.
