Abstract (en)
[origin: EP0032880A2] A preheating device for preliminary heating the liquid of the cooling circuit of a motor-vehicle engine comprising a heater (10) formed by a massive metallic cylindrical body (14) having an axial through cavity (20) adapted to be connected to the cooling circuit of the engine and two axial bores (22) each containing an armored heating resistor (24), an electric pump (12), and an electric feeding circuit (50, 51, 52, 54) for connecting the device to an electrical source disposed outside the motor-vehicle. The electric circuit comprises a switch controlled by a programmable timer (54).
