Abstract

The invention discloses a starting control method for hydrogen fuel engines, which is characterized in that a camshaft fluted disc adopted in the method comprises two wide teeth and two narrow teeth, the two wide teeth are adjacently arranged, and the two narrow teeth are also adjacently arranged, and a camshaft angle corresponding to the sum of the width of each tooth and the width of a tooth gap is 90 degrees; when the rotating speed is less than 50 turns / minute, operations of hydrogen spraying and ignition setting and throttle operations are not performed; when the rotating speed is 50-150turns / minute, the operations of hydrogen spraying and ignition setting are still not performed, but when detecting that the rotating speed is greater than 50 turns / minute, the first eight turns of throttles of an engine are immediately controlled to be completely opened, and then closed; when the rotating speed is 150-400 turns / minute, the operations of hydrogen spraying and ignition setting are realized by using crankshaft signals; when the rotating speed is greater than 400 turns / minute, a crankshaft phase is determined according to the crankshaft signals, and then the operations of hydrogen spraying and ignition setting are performed according to the crankshaft phase; and when the rotating speed is greater than 1000 turns / minute, the starting operation is completed, and then the engineis in an idle state. By using the starting control method disclosed by the invention, the control accuracy of the first half phase of a starting operation can be ensured.

Description

technical field

[0001] The invention relates to the field of engine electronic control, in particular to a hydrogen engine startup control method based on section control. Background technique

[0002] Energy and environmental issues are two bottlenecks restricting the development of the automotive industry. Studies have shown that automobile exhaust has become a major cause of air pollution. The "2030 Vision Report on the Transition of the United States to a Hydrogen Economy" believes that oil resources may be exhausted in 25 to 30 years. Optimistically, after the middle of the 21st century, oil resources will also face depletion.

[0003] As a clean, efficient, safe and sustainable energy, hydrogen energy is regarded as the clean energy with the most development potential in this century. Hydrogen burns to produce water, no CO at all 2 and various pollutants, it is an ideal fuel for the engine. The use of hydrogen as engine fuel can solve the energy, environmental pol...
