Said equipment includes the following several portions: internal combustion engine intake pipe, internal combustion engine control device, internal combustion engine intake manifold, hydrogen gas injection duct and non-return valve assembly, internal combustion engine cylinder head and internal combustion engine intake valve. Said invention also provides its working principle and concrete operation method.
Description
Technical field
Hydrogen Energy is considered to the desirable alternative energy source of future transportation transportation, has efficient height, zero feature of polluting.Using hydrogen in traditional Vehicular internal combustion engine, is the effective way that a Hydrogen Energy is utilized.
Background technique
Hydrogen fuel injection method and device are one of key problem in technology of hydrogen-fueled internal combustion engine (being called for short the combustion hydrogen internal combustion engine).The injection of hydrogen fuel is divided into two kinds of main types: to the engine charge pipe inspection with to the engine air in-cylinder injection.The present invention is a kind of injection method and device that is applied to intake manifold injection type hydrogen fuel.
Summary of the invention
The present invention proposes a kind of be used to fire hydrogen internal combustion engine suction tude hydrogen fuel injection method and device, and this method and apparatus is applicable to that all are the internal-combustion engine that fuel adopts suction tude hydrogen spray regime with hydrogen.Enforcement of the present invention can solve the tempering problem of suction tude hydrogen injection.
By the hydrogen of snifting valve ejection via a conduit that is installed on the band safety check on the inlet manifold of IC engine to spraying near the position of air-intake of combustion engine gate seat, its advantage is:
The shortest path that enters cylinder is arranged when 1, making hydrogen injection, and then it is the least possible to remain in the hydrogen of suction tude;
2, safety check can will remain in hydrogen in the jet pipe and be retained in the jet pipe and isolate with intake duct when jet finish.
Thus, can stop the generation of suction tude tempering, the difficult problem that the suction tude tempering when solving hydrogen-fueled internal combustion engine employing intake manifold injection mode is blown out.
Description of drawings
Structure of the present invention is provided by the following drawings and example:
Fig. 1 hydrogen injection guidance system schematic representation
Fig. 2 hydrogen injection conduit and safety check assembly decomposing schematic representation
1, intake lines of combustion engines 2, hydrogen injection conduit and safety check assembly 3, cylinder head of internal combustion engine 4, internal combustion engine intake valve 5, hydrogen injection conduit 6, pipe joint 7, gas-tpe fitting 8, pump check valve ball 9, check-valve spring 10, check-valve nozzle
Embodiment
As shown in Figure 1, 2, the present invention includes hydrogen injection conduit and the safety check assembly that is installed on the suction tude.This assembly is by forming with lower member: hydrogen injection conduit 5, pipe joint 6, gas-tpe fitting 7, pump check valve ball 8, check-valve spring 9, check-valve nozzle 10.
The hydrogen that comes from the hydrogen snifting valve ejection of engine controlling unit control, link to each other with gas-tpe fitting 7 via one section pipeline and to enter hydrogen injection conduit 5, be applied to pressure on the pump check valve ball 8 owing to be higher than check-valve spring 9 from the Hydrogen Vapor Pressure of snifting valve, pump check valve ball overcomes the sealed seat surface that spring force leaves the hydrogen injection conduit, and hydrogen then sprays to the suction port at suction valve cone place by check-valve nozzle 10.Closing the hydrogen snifting valve when engine controlling unit stops when jet, Hydrogen Vapor Pressure in the injection catheter sharply descends, pump check valve ball revert to the injection catheter sealed seat surface under the effect of check-valve spring power, stop remaining hydrogen to enter intake duct, and then the hydrogen tempering can not take place in suction tude.
Claims (3)
1, a kind of internal combustion engine hydrogen fuel injection method and device comprise the hydrogen injection conduit and the safety check assembly (2) that are installed on the intake lines of combustion engines.This assembly is by hydrogen injection conduit (5), pipe joint (6), gas-tpe fitting (7), pump check valve ball (8), check-valve spring (9), check-valve nozzle (10).
2, hydrogen fuel injection method according to claim 1 and device, it is characterized in that injection catheter and safety check assembly are installed in suction tude near air-intake of combustion engine gate seat place, enter cylinder of internal-combustion engine after making hydrogen in suction tude, experience the shortest path, and then almost do not have hydrogen to remain in the suction tude.
3, hydrogen fuel injection method according to claim 1 and device, it is characterized in that pump check valve ball (8) is in and the normally closed position of injection catheter (5) under check-valve spring (9) effect, hydrogen circulation path between blocking-up injection catheter (5) and check-valve nozzle (10) is to guarantee that residuing in this hydrogen injection valve to the hydrogen in the injection catheter (5) when the hydrogen injection valve of being controlled by combustion engine control cuts out can not enter intake lines of combustion engines.
