    摘要： An internal combustion engine includes a pre-chamber. In another aspect, pressure within a pre-chamber is equal to or greater than pressure within a main combustion chamber at least prior to ignition in the main combustion chamber. A further aspect provides a supplemental piston creating pressure and supplying a fuel-air mixture into a pre-chamber, and a spark or glow plug has an end located within the pre-chamber for ignition of the mixture therein. In yet another aspect, internal combustion engine control software automatically controls pressure within a turbulent jet ignition pre-chamber, controls a valve-actuator to admit a fuel-air charge into the pre-chamber, and causes an ignitor to initiate combustion in the pressurized pre-chamber. This also permits the rate of combustion to be controlled in the primary chamber regardless of the air-fuel ratio or the diluent fraction in the main chamber. Another aspect employs a pre-chamber purge pump with separate air and fuel injection. Moreover, an additional aspect separately supplies unmixed air and fuel into a turbulent jet ignition pre-chamber through a dual-mode, single injector unit.

    摘要： A jet ignition internal combustion engine of the type provided with separate induction passages for lean and rich air-fuel mixtures wherein the main inlet valve mounts a cup like member forming an auxiliary ignition chamber within the main combustion chamber. The rich mixture is supplied to the auxiliary chamber through the hollow stem of the main inlet valve, flow being controlled by a small auxiliary valve within the main valve and actuated by the same valve gear. Openings in the wall of the valve-carried ignition chamber connect with spark ignition means and with the main combustion chamber to provide for spark ignition of the rich ignition chamber mixture and resultant jet ignition of the lean mixture in the main combustion chamber.

    摘要： An internal combustion engine with an auxiliary combustion chamber is provided with a main combustion chamber for the combustion of an air-fuel mixture, an auxiliary combustion chamber communicating with the main combustion chamber through a passage, such that the ignition of an air-fuel mixture in the auxiliary combustion chamber induces ignition and combustion of the air-fuel mixture in the main combustion chamber, and an intake valve provided in the auxiliary combustion chamber for opening and closing a passage which leads to a fuel supply means. The engine further includes an intake valve lifter having a piston member which is associated with the intake valve and a cylinder member in which such piston member moves, a fluid pressure supply device driven in synchronism with the rotation of the engine to supply a fluid pressure, and a fluid pressure supply passage for feeding the fluid pressure which is supplied by the fluid pressure supply device to the intake valve lifter. Accordingly, the control of the opening and closing operations of the intake valve of the auxiliary combustion chamber can be performed in accordance with any driving conditions by feeding the fluid pressure supplied by the fluid pressure supply device to the intake valve lifter through the fluid pressure supply passage and moving the piston member in synchronism with the rotation of the internal combustion engine.
