Embodiment Construction

[0027] The present invention will be further described below in conjunction with accompanying drawing:

[0028] Such as figure 1 As shown, in this embodiment, a device for realizing rapid start and stop of ignition-type internal combustion engines with hydrogen gas retains the original flywheel 1, starter gear 2, starter control relay 3, original machine electronic control unit 5, and ignition module on the internal combustion engine. 7. On the basis of the spark plug 8 and the fuel nozzle 9 of the original machine, a hydrogen supply device and an electronic control unit 4 are installed;

[0029]The hydrogen supply device includes a hydrogen bottle 6 , a hydrogen nozzle 10 , a hydrogen pressure regulator 11 and a hydrogen pressure sensor 12 . The hydrogen cylinder 6 is connected to the hydrogen gas nozzle 10 through the hydrogen gas supply pipeline, the hydrogen gas nozzle 10 is installed on the intake manifold of each cylinder of the internal combustion engine, the hydrogen ...

Abstract

The invention provides a device utilizing hydrogen gas to realize quick start and stop of an ignition internal-combustion engine and a control method thereof and particularly relates to control of combustion and quick start and stop of an internal-combustion engine. A hydrogen gas supply device and an electronic control unit are additionally arranged on the basis of reserving all parts of the internal-combustion engine body. The electronic control unit can judge and control stop and running of the internal-combustion engine according to revolution speed of the internal-combustion engine, automobile speed and position of a throttle valve to reduce idling running time of the internal-combustion engine greatly so that waste of energy of the internal-combustion engine during idling and harmful emission are reduced. Besides, since pure hydrogen gas is used as fuel to start the internal-combustion engine quickly, the start time is shortened, and fuel consumption and harmful emission of the internal-combustion engine during starting are decreased.

Description

technical field [0001] The invention provides a device and a control method for realizing quick start and stop of an ignition type internal combustion engine by using hydrogen, and the specific content relates to the control of combustion, quick start and stop of the internal combustion engine. Background technique [0002] When the internal combustion engine is idling, it does not output useful work to drive the vehicle forward. When the road is congested or waiting for traffic lights, the driver will control the vehicle to stop. If the engine is not turned off at this time, the internal combustion engine running at idle speed will still consume fuel, resulting in waste of fuel and pollution of the environment. [0003] In view of the above problems, the BSG technology currently used can automatically stop the operation of the internal combustion engine in the parking state, and use the starter motor to quickly drag the engine to a higher speed when the driver steps on the ...
