Abstract: A protection device for preventing automobile engines from abnormal starts comprises automobile batteries (10), a start motor (20) and a control circuit (30) disposed therebetween. The control circuit (30) comprises a main control unit MCU1, a start switch (31), a start relay (321) and a power supply relay (322), the coil of the start relay (321) being connected to the automobile batteries (10) through the normally closed contact of the power supply relay (322). The start relay in the present invention is connected to the batteries rather than directly but through the normally closed contact of the power supply relay. In addition to being controlled by the main control unit, the start relay is also controlled by the power supply relay, thereby providing additional insurance and more effective protection so as to avoid the damage of the start motor due to erroneous actions.
