摘要： An air/fuel mixture is ignited in an internal combustion engine by receiving the air/fuel mixture as an incoming air/fuel mixture flow from a main combustion chamber of the internal combustion engine into an enclosure adjacent the main combustion chamber. The enclosure defines a first chamber enclosing first and second ignition bodies and the enclosure defines a second chamber adjacent the first chamber and connected to the first chamber via a passage. A portion of the air/fuel mixture received in the enclosure is directed toward an ignition gap between the first and second ignition bodies and another portion is directed into the second chamber. The air/fuel mixture is then ignited in the ignition gap, and flame from combustion in the first chamber is ejected into the main combustion chamber. Then, flame from combustion in the second chamber is ejected into the main combustion chamber.

摘要： The present disclosure relates to a method for operating an internal combustion engine operating at least partly on gaseous fuel. The internal combustion engine has a main combustion chamber (8) and a pre-combustion chamber assembly (20) with a pre-combustion chamber (36), a gaseous fuel supply channel (46) for supplying gaseous fuel into the pre-combustion chamber (36), and an ignition fuel injector (34) for supplying ignition fuel into the pre-combustion chamber (36). The method may comprise supplying a predefined amount of gaseous fuel into the pre-combustion chamber (36) via the gaseous fuel supply channel (46) for enriching the pre-combustion chamber (36) with gaseous fuel at times between about 210° crankangle before the top dead center and about 180° crankangle after the top dead center, and supplying a predefined amount of liquid ignition fuel into the gaseous fuel enriched pre-combustion chamber (36) via the at least one liquid ignition fuel injector (34).

摘要： This auxiliary chamber type engine is provided with a cylinder, a cylinder head disposed on the top part of the cylinder, and a piston which is arranged to reciprocate inside the cylinder and which defines a main combustion chamber between the cylinder head. The cylinder head contains an auxiliary combustion chamber forming part which defines an auxiliary combustion chamber that communicates through the main combustion chamber and an injection hole. The auxiliary combustion chamber contains: a first passage part which is cylindrical and which extends upward from the injection hole; a second passage part which extends upward from the first passage part and which has a cross-sectional area that becomes larger as the part extends upward; and a cylindrical space part which extends upward from the second passage part and in which is arranged an ignition plug. Assuming that a straight line comprising an axis of the first passage part and an extended line of the axis is a straight line L, a center O of a cross-section perpendicular to a line L is eccentric to the straight line L.

摘要： A system for igniting a mixture in an internal combustion engine includes an elongate plug body generally residing around a center longitudinal axis and adapted to couple to the internal combustion engine. The system also includes a first ignition body residing about an end of the plug body and a second ignition body adjacent the first ignition body to define a flame kernel initiation gap between the second ignition body and the first ignition body. The system also includes a transversely extending cap at the end of the plug body that is longitudinally spaced from the plug body by a support comprising a leg that is radially offset from the center longitudinal axis, the support defining a peripheral opening around a perimeter of the cap where a total radially-facing area of the support is less than a total area of the peripheral opening.

摘要： A process (800) is provided for improving combustion control and fuel efficiency in rotary and reciprocating IC engines by enabling leaner combustion at higher compression ratios using less heat for ignition. Embodiments employ secondary chambers (32) of minimal total volume within a cylinder periphery (36). These chambers (32) communicate with a main chamber (34) via conduits (42) and enable a radical ignition ("RI") species generation and supply process that starts in earlier cycles to be augmented and used in later cycles. Measures regulate the RI species generated and provided to the main chamber (34). These species alter dominant chain-initiation reactions of the combustion ignition mechanism. Also employed when preferable are fluids of higher heat of vaporization and volatility but lower ignitability than the fuel. This process improves combustion in radical ignition engines and radical augmented spark and compression ignition engines.
