Abstract

The invention comprises a gaseous fuel injector (10) for supplying gaseous fuel to a gaseous fuel combustion engine. The gaseous fuel injector (10) comprises an injector housing (12) adapted to receive an injector assembly (28) and supply gaseous fuel thereto. The injector housing (12) has an inlet at a first end, a nozzle (20, 20') with an outlet (14) at a second open end (26, 26') and a chamber(16) between the inlet and the outlet (14). The injector housing (12) comprises an ignition arrangement at the second open end (26, 26'). The invention also extends to a gaseous fuel combustion enginecomprising a gaseous fuel injector (10) and an ignition arrangement according to the invention.

Description

technical field [0001] The present invention generally relates to the field of gaseous fuel injectors. In particular, but not exclusively, the present invention relates to improved ignition arrangements for gaseous fuel injectors in gaseous fuel combustion engines. Background technique [0002] Gas fuel combustion engines use gaseous fuels such as compressed natural gas (GNG) or liquefied natural gas (LNG). These engines require gaseous fuel injectors to supply a calculated amount of gas to the combustion chamber of the engine for ignition. [0003] A gaseous fuel injector includes a nozzle with a valve at an outlet end. In what is known as spark ignition port injection (SI-PI) gas fueled engines, gas is supplied into the inlet manifold and from there, valves control the flow of gas into the combustion chamber for ignition by means of an ignition source. This mechanism is usually obtained by modifying an existing gasoline engine which has proven to be inefficient. The ig...
