Embodiment Construction

[0012] Refer below figure 1 with 2 The invention is described in more detail.

[0013] figure 1 is a schematic block diagram of an internal combustion engine 10 comprising a main combustion chamber 11 and a pre-chamber 12 according to the invention. Fuel and combustion air or a mixture of fuel and combustion air enters in the direction of arrows 13 and 14 into the main combustion chamber 11 of the internal combustion engine 10 , which is preferably formed as a compression ignition gas engine. Fuel combustion takes place in the main combustion chamber 11 , exhaust gases being discharged from the main combustion chamber 11 in the direction of the arrow 15 .

[0014] Fuel is likewise introduced into the prechamber 12 in the direction of the arrow 16 . The pre-chamber 12 is connected to the main combustion chamber 11 via a vent 17 or a ventilation pipe, wherein the corresponding medium is exchanged between the main combustion chamber 11 and the pre-chamber 12 in the direction ...

Abstract

The invention provides an internal-combustion engine and an injection device, relates to the internal-combustion engine, especially a fuel gas engine, which comprises a main burning room (11) and at least one pre-burn room (12) connected to the main burning room (11). Wherein, the ejector (19) of pre-burn room can eject fuel gas to the pre-burn room (12); the ejector (19) comprises a nozzle pin valve (20) which can close or open the eject nozzle (23). With said invention, the nozzle pin valve (20) can be directly operated by the controllable magnet (25), while the magnet (25) is powered, the magnet will release the eject nozzle (23) to overcome the close force of spring element (24) to adsorb the eject pin valve (20); and while the magnet (25) is not powered, the spring element (24) seals the eject nozzle (23), will press the eject pin valve (20) on the eject nozzle (23).

Description

technical field [0001] The invention relates to an internal combustion engine, in particular a gas engine. Background technique [0002] Compression-ignition internal combustion engines, such as gas engines, have a main combustion chamber into which fuel and combustion air or a fuel / combustion air mixture are drawn in, where the fuel is combusted and exhaust gases exit the main combustion chamber. At least one pre-chamber is connected to the main combustion chamber through vents or ducts. Fuel is injected into the or each pre-chamber by means of at least one injection device corresponding to the corresponding pre-chamber, wherein the or each injection device respectively has an operable injector needle valve according to its respective The position closes or opens the injection port of each injection device. Such internal combustion engines are known from DE 44 19 429 C2 and DE 196 21 297 C1. [0003] According to the prior art, the injector needles of injection systems a...
