摘要： In a gas engine a passage (18) for supply of fuel gas to the pre-combustion chamber (12) is provided with a check valve (24) adapted to be opened by negative pressure in the pre-chamber (12). The check valve (24) comprises a valve body (135) on a valve stem (134) which is slidably fitted into valve guide means (132, 133) closed by a cylindrical cap (139). To improve the valve opening characteristics pressures across the valve body and stem are balanced by a connecting passage (50;60;70) between a lower space (138) in the valve guide means (133), which connects to the pre-chamber (12) only when the valve body (135) opens, and an upper space (130) in the cap (139). Further, to avoid contamination, the end (48,67,72) of the connecting passage (50,60,70) which opens into the upper space (130) is spaced from an end (143, 77) of a pipe (21) which supplies lubricating oil thereto.

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.
