FIELD: internal combustion engines.
SUBSTANCE: invention can be used in internal combustion engines. Dual turbocharger system contains first bypass valve (202A), containing valve (206A) of the first bypass valve, second bypass valve (202B), containing valve (206B) of the second bypass valve and an actuator bypass valve. Bypass valve actuator is connected to each of valves (206A), (206B) of the first and second bypass valves to change the opening degree of valve (206A) of the first bypass valve and valve (206B) of the second bypass valve according to the required supercharging. Valve (206A) of the first bypass valve is connected to the actuator of the bypass valve through first washer (220A) through first lever mechanism (222A). Valve (206B) of the second bypass valve is connected to the actuator of the bypass valve via second washer (220B) through second lever mechanism (222B). First and second washers (220A) and (220B) are located inside tank (216). Tank (216) is designed the way the increased pressure of the fluid supplied to the reservoir pushes first and second washers (220A) and (220B) outward, reducing corresponding valve lifts (206A) of the first bypass valve and valve (206B) of the second bypass valve. Reduced fluid pressure supplied to tank (216) brings first and second washers (220A) and (220B) closer to each other, increasing corresponding valve lifts (206A) of first bypass valve and valve (206B) of the second bypass valve. Dual turbocharger system variant and method for a dual turbocharger system is disclosed.
EFFECT: technical result is to improve the accuracy of the boost pressure supplied to each bank of cylinders.
