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. 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 igniter 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.

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.
摘要翻译： 内燃机包括预燃室。 在另一方面，至少在主燃烧室内点燃之前，预燃室内的压力等于或大于主燃烧室内的压力。 另一方面提供了一种补充活塞，其产生压力并将燃料 - 空气混合物供应到预燃室中，并且火花塞或电热塞具有位于预燃室内的端部，用于在其中点燃混合物。 在另一方面，内燃机控制软件自动控制湍流喷射点火预燃室内的压力，控制阀致动器以允许燃料 - 空气装料进入预燃室，并使点火器在加压 预制室。 这也允许在主室中控制燃烧速率，而不管主室中的空燃比或稀释剂馏分如何。 另一方面采用具有单独的空气和燃料喷射的预室清洗泵。 此外，附加方面通过双模式单个喷射器单元将未混合的空气和燃料独立供应到湍流喷射点火预燃室中。
