ENGINE (VERSIONS) Russian patent published in 2011 - IPC F02B39/16 

FIELD: engines and pumps.

SUBSTANCE: engine ensures the possibility of constant determination of the number of revolutions of supercharger with reduced computational load of engine control module (ECM). Engine (1) is equipped with base component (8) of engine, which consists of many cylinders and supercharger (7), angular sensor (4) of crankshaft, turbosensor (5) that determines rotation of supercharger (7) as pulse signals, amplifier (11) that divides pulse signals into arbitrary division factor and calculates divided pulse signals, and ECM (10) that evaluates the state of surging of supercharger (7); at that, ECM (10) sets the specified position of piston of each cylinder as to angle of rotation of crankshaft of engine base component (8) to time tag of the beginning of counting of divided pulse signals, supplies divided pulse signals counted from time tag of the beginning of the counting to the number of the specified revolutions as the first output signal, and evaluates that if difference between the first output signals in each cylinder is more than the specified value, supercharger (7) is in surging state.

EFFECT: determining the number of revolutions of supercharger with reduced computational load.
