ABSTRACT LOW TEMPERATURE STARTING SYSTEM FOR INTERNAL COMBUSTION ENGINES The system is based on incorporating a start preturbine (80) capable of injecting pressurised air in the inlet manifold (10) of the motor (2). The preturbine (80) is driven by air supplied by a storage reservoir (68) and starts operating after an air starter motor (46) has been actuated. Operation is continued until, as a result of the ignition of the fuel, the engine (2) attains a high speed, after which the starter motor (46) and the preturbine (80) are disengaged, whereby the engine decelerates. When the engine reaches a preset low speed, the preturbine (80) is reengaged and stages of operation of the preturbine (80) coinciding with engine acceleration alternate with inoperative stages coinciding with engine deceleration until an engine speed above the low speed is maintained. A electronic sequencer (90) controls the successive operations. Figure 1.
