FIELD: engines and pumps.
SUBSTANCE: distributing sensor of gasoline engines operating on gasoline and gaseous types of fuel includes housing, two Hall sensors (1, 2), screen (3) with slots (according to the number of cylinders), centrifugal and vacuum automatic devices to change the ignition advance angle (IAA), rotor (4), cover (5), relay (7), and microchip (8). One Hall sensor (1) has the possibility of generating the spark formation signals corresponding to optimum IAA at the engine operating on gasoline. The other Hall sensor (2) has the possibility of generating the spark formation signals corresponding to optimum IAA at the engine operating on gaseous types of fuel. Hall sensors are connected to microchip through the relay with possibility of disconnecting the first sensor (1) when the other one (2) is actuated. The second Hall sensor (2) can be located on the housing through (180 - α/2)° from the first one (1) in rotation direction of the screen. Where αº - is difference between optimum IAA at operation of the engine on gasoline and on gaseous types of fuel.
EFFECT: providing automatic correction of optimum IAA at engine operation on gasoline and on gaseous types of fuel, reducing the fuel flow rate, intensity of wear and content of hazardous substances in waste gas.
