<p>A protection system for a diesel engine of battery-less operation comprises a normally unenergized solenoid valve (104) for fuel flow shutoff; a current generator (3) able to provide sufficient current for energizing said solenoid valve down to below a certain predetermined engine r.p.m.; a decompression device (8) which comes automatically into operation at a rotational speed at least equal to said predetermined engine r.p.m.; and a control centre for receiving signals from at least one transducer for an engine operating parameter, for comparing said signal with a limiting alarm signal, and for energizing said solenoid valve with a predetermined delay. <IMAGE></p> |
