Abstract: A sealing structure of a rotary valve in an internal combustion engine in which a recess is formed either at an opening portion of a rotary valve proper or at an opening portion of a combustion chamber in a housing and in which a seal member slidably fitted in the recess is resiliently pushed against the opposing part by means of a spring member. An annular resilient member is interposed between the lower surface of the seal member and the opposing bottom surface of the recess in such a manner that the two ends of the resilient member are respectively in contact with the surfaces of the seal member and the recess. Thereby, the contact pressure at the ends of the resilient member is increased by utilizing the gas pressure in the combustion chamber. Further, the pushing force of the seal member against the opposing part is increased, so as to enhance sealing efficiency.

Abstract: An auxiliary intake passage system for internal combustion engines having a main carburetor delivering a lean mixture to main combustion chambers through a main intake passage, and an auxiliary carburetor delivering a rich mixture to auxiliary combustion chamber through an auxiliary intake passage. The auxiliary intake passage system is comprised of an induction passage leading from the auxiliary carburetor to an auxiliary intake distribution chamber. A plurality of branch passages extend laterally from said auxiliary intake distribution chamber and lead to the auxiliary combustion chambers. The induction passage comprises a first portion of substantially uniform cross-sectional area connected to a second portion which is tapered and so formed that the internal wall of the tapered section is outside the axial projection of the internal wall of the first portion, thus minimizing resistance to fluid flow and improving fuel distribution and homogenation to each combustion chamber.

Abstract: An internal combustion engine has a main combustion chamber and an auxiliary combustion chamber associated with each piston and connected by a torch opening. A lean mixture is supplied to the main combustion chamber and a rich mixture is supplied to the auxiliary combustion chamber. After compression, ignition of the mixture in the auxiliary combustion chamber projects a flame through the torch opening to burn the lean mixture in the main combustion chamber. In order to prevent an over-rich mixture developing in the auxiliary combustion chamber upon rapid acceleration of the engine, correction devices and systems are employed to reduce the ratio of air intakes or to supply secondary air during such rapid acceleration. Such correction systems and devices may be rendered inoperative during initial startup of the engine.

Abstract: A three-valve stratified-charge internal combustion piston engine has an auxiliary combustion chamber connected to each main combustion chamber through a torch nozzle. A rich mixture is supplied to the auxiliary chamber and a lean mixture is supplied to the main chamber. A portion of the exhaust gases from the main chamber is recirculated through a control valve to mix with the rich mixture supplied to the auxiliary chamber. For loaded conditions of the engine, additional exhaust gases from the main chamber are recirculated through a control valve to mix with the lean mixture supplied to the main chamber. The control valves are automatically operated by means responsive to engine operating conditions.
