good morning<\/p>\n

Today I am describing the new turbocharger adopted on the Fiat Tipo 1600 mjet with electric drive. It is a new Honeywell turbine model type GTD 1449VZ with variable geometry with Hella rod control unit.<\/span><\/p>\n

The main feature is the lack of a piping circuit and solenoid valves to control the variable geometry.<\/p>\n

We find an electric actuator with a control unit positioned on the turbine body. This system has an undoubted advantage in simplifying the system as the vacuum tubes and solenoid valve are eliminated. In the event of a failure, the Hella turbine and electric actuator assembly must be replaced. We assume that in the future it is likely that spare parts will be provided to carry out the overhaul.<\/p>\n

\"\"<\/p>\n

How does the system work in practice?<\/strong><\/p>\n

The engine control unit receives the boost pressure signal via the turbocharger pressure sensor, processes it and then checks the actual position of the variable vanes via a position sensor. At this point, to increase the turbo pressure, it sends an actuation command to move the turbine blades by means of a PWM-modulated electrical signal to the control unit located on the turbo.<\/p>\n

PWM control makes it possible to optimise the current consumption of the motor that moves the rod controlling the variable turbo geometry. compressor.<\/p>\n

\"\"\"\"<\/p>\n

The system is under direct control of the engine management ecu, and in the event of faults, a specific error code can be detected.<\/p>\n
