Apparatus and method for controlling internal combustion engine with hydrogen fuel

Abstract

The invention relates to a method for controlling feeding fuel to the inlet pipe of hydrogen motor and relative device, which can apply variable combustion engine with hydrogen fuel and it can apply electric control on the hydrogen ejection time and ejection period. The invention comprises a group of sensors to supply the information of hydrogen feeding system and the motor; a group of valves and pipeline to supply hydrogen resource; a electric control unit as the control center of said device; a hydrogen ejection system formed by a hydrogen stable-pressure rail, a hydrogen ejection valve, and hydrogen guide nozzle for guiding the hydrogen ejected from hydrogen ejection valve to nearest inlet valve; a electric air-saving gate on the inlet pipe of motor, a waste gas recycle valve between the inlet pipe and outlet pipe; and a hydrogen safety release valve on the crank box of motor. The invention ejects the hydrogen at the position which is nearest to the motor inlet valve into burning room, to reduce the backfire possibility of inlet pipe, reduce the discharge of NOx and control early-burning.

Description

technical field [0001] The invention relates to a control method and device for a hydrogen-fueled internal-combustion engine applied to a hydrogen-fueled internal-combustion engine (hydrogen engine for short). During the working process of a hydrogen engine, whether hydrogen is injected into the intake manifold or directly injected into the cylinder, the hydrogen fuel requires a special injection device to inject the gas into the intake port or the combustion chamber in the cylinder and use electronic control to make the engine work normally. run. Therefore, according to actual needs, a hydrogen fuel injection and control device for hydrogen engines is designed. Background technique [0002] With the continuous depletion of oil resources, rising oil prices, and continuous upgrading of emission regulations, in order to completely liberate from the dual pressures of environmental protection and energy crises, the search for alternative energy sources has always been concerned...

Problems solved by technology

Although the fuel cell has the advantages of high power, high efficiency and no pollution, its development cost and product price are quite expensive, its driving range and life are limited, and there is still a considerable distance from large-scale industrial applications.
