The injection/ignition system on the 2387 JTD 150 CV version of the Lancia Thesis is managed by the Bosch EDC 15C- 7-2.2 direct injection control unit with a variable geometry turbocharger, intercooler and common rail type electronic engine management system.The injection control unit controls the injectors and, manages their opening through the engine load (air flow rate, engine temperature).The control unit also controls the low pressure supply pump for supplying the circuit.The high pressure pump, on the other hand, is controlled by a pressure regulator operated by the control unit on the basis of the engine parameters.Its main features are:
availability of high pressure (up to 1350 bars)
possibility of modulating pressures between 150 bars up to a maximum service pressure of 1350 bars, regardless of engine speed and load
ability to work at high engine rpms (up to 6000 rpm)
injection control precision (injection advance and duration)
reduction in fuel consumption
reduction in emissions.
Main system functions are essentially as follows:
fuel temperature control
engine coolant temperature control
control of amount of fuel injected
Idle speed check
Fuel cut-off during over-run
cylinder balance check when idling
control of anti-judder function
exhaust fume control during acceleration
exhaust gas recirculation control (E.G.R.)
maximum torque limit control
maximum speed limit control
control of glow plugs
control of climate control system activation (where fitted)
