Abstract
PURPOSE: To improve intake efficiency and reduce fuel consumption and HC emissions, by applying a pump, which supplies air or a thin mixture under pressure, and another pump, which supplies a thick mixture of theoretical concentration or more under pressure, to an engine so that the top dead centers of these pumps do not coincide with each other as to time.
CONSTITUTION: A mixture of theoretical concentration or a thick mixture through a bore 35 and a check valve 31 and air or a thin mixture through a bore 36 and a check valve 32 are sucked into chambers M, A in which negative pressure is caused by pistons 37, 38 moving toward the bottom dead centers. Since the phase of the piston 38 precedes that of the other piston 37, the thin mixure first opens a valve 28 and then and proceeds and raises its pressure in a scavenged gas confluence chamber 5 whose exhaust port 3 is closed. The thick mixture first enters into a combustion cylinder 2 in which the pressure is reduced due to the discharge of exhaust gas through an exhaust port 4. At that time, the thin mixture performs scanvenging. After that, the thick mixture enters into the combustion cylinder. Efficient scavenging is thus enabled.
