DMCI ENGINE MANAGEMENT SYSTEM
схема управления двигателем DAF XF 105, обвязка и датчики топливной системы
The DMCI electronic unit needs different input signals to control engine and vehicle functions and various components are activated by output signals. Input signals The most important input signals are: - clutch proximity switch (E575) - service brake (G469) - accelerator pedal sensor (F672) - neutral position switch (F593/F599) - oil level sensor (F673) - 2nd coolant temperature sensor (F743) - coolant temperature sensor (F566) - air inlet boost pressure and temperature sensor (F649) - engine oil pressure and temperature sensor (F744) - fuel pressure and temperature sensor (F713) - crankshaft sensor (F552) - camshaft sensor (F558) - electronically controlled fan clutch (B335) - glow relay (G014)
Output signals After processing of the input signals, output signals control the following components: - electronically controlled fan clutch (B335) - red warning VIC-2 (D310) - waste gate valve (B368) - starter motor (B010) - exhaust brake valve (B192) - DEB solenoid valves (B411 to B416) - glow relay (G014) - pump units (B131 to B136) - injectors (B421 to B426)
The DMCI communicates with the various other electronic systems in the vehicle via the CAN network.
ELECTRICAL SYSTEM The electronic unit is the central control device of the DMCI engine management system. The functions can be split into engine functions and vehicle functions. Note: Functions may be optional or may depend on the vehicle configuration. Engine functions: - system status - CAN controls - pre-glowing and after-glowing - control of fuel supply - cylinder detection and synchronisation - fuel injection when starting - injection timing control - idling control - turbocharger pressure control - smoke limitation - full-load limiting and engine protection functions - engine brake control - fan clutch control Vehicle functions: - Cruise control - downhill speed control - vehicle speed limiting prescribed by law - variable vehicle speed limiting - vehicle speed limiting for special applications - engine speed control - CAN controls остальной материал по ремонту DAF DAF 95 XF электрическая схема |
