FIELD: emergency start of internal combustion engine in case of failure of rotational speed sensor.
SUBSTANCE: Specification describes method of starting the internal combustion engine equipped with starter and rotational speed sensor whose output signal is proportional to rotational speed of internal combustion engine shaft. Provision is also made for measuring the onboard voltage of automobile power supply system for change (3) of voltage of storage battery during and after start of internal combustion engine. In the course of starting (1) the internal combustion engine with starter in operation, angular position of crankshaft is determined by change (3) in storage battery voltage.
EFFECT: possibility of determination of angular position of crankshaft in case of failure of rotational speed sensor by analyzing the storage battery voltage at starting the engine by means of starter.
