Abstract

An apparatus for heating liquid cooled engines, comprising an engine heater tube (8) adapted to be connected to a low level cooling water passageway (2) of an engine block (3), for instance between cut off ends of a hose (9) or a tube belonging to the cooling system of the engine, inside which engine heater tube (8) there is mounted an electric resistance heater element (10) formed as a sling and connected to an electric output, and through which cooling water is introduced in the engine block (3), and in which means (4, 5, 6, 7) are provided for connecting the engine heater element to an electric source of current, which is an accumulator battery (13) adapted to be charged by the engine itself, and in which the apparatus comprises a thermostat (4) which is connected to the battery (13) for disconnecting the supply of current to the engine heater element (10) when the cooling water adjacent said element (10) has reached a predetermined temperature, further a timer (6) for adjustably setting the start/stop position at certain predetermined periods of time and/or setting of a predetermined operation time, and a voltage guard (5) which is connected parallely to the timer (6) and the thermostat (4) for disconnecting the entire apparatus when the voltage over the battery poles is below a predetermined value.
