INTERNAL COMBUSTION ENGINE Russian patent published in 2003 - IPC

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: proposed engine with distributed injection of fuel contains intake branch pipe limited buy intake valve from side of combustion chamber and communicating through vacant end with space of receiver connected by intermediate pipe to space of chamber of air clearance equipment with air intake branch pipe. According to invention, dynamic lengths of intake branch pipe L₁ and air suction branch pipe L₃ are equal and are tuned to one and the same natural resonance mode of vibrations of air volume enclosed in space of corresponding branch pipes, and device to suppress suction noise is made in form of end 1/4 wave resonator built air suction branch pipe and arranged along axis of air suction branch pipe in its entry part. Open dynamic cut of resonator is located in middle of air suction branch pipe. Invention improved efficiency of suction noise damping. EFFECT: simplified design of system. 2 cl, 2 dwg
