Plug-in hydrogen hybrid fuel vehicle

Abstract

The invention provides a plug-in hydrogen hybrid fuel vehicle, and in particular, relates to a technology of fuel control of an internal combustion engine and vehicle-carried hydrogen production. The system is added with a set of hydrogen production, storage and supply system and a hydrogen system electric control unit on the basis of retaining all parts of an internal combustion engine body. The hydrogen system electric control unit can detect a voltage state of a generator and information of an external charge pile when the pressure of a hydrogen storage system is low; the external charge pile is preferentially selected to drive a vehicle-mounted hydrogen producer to produce hydrogen; when no external charge pile is provided, the generator can produce the hydrogen along with the vehicle; and the hydrogen storage system automatically stops production of the hydrogen when reaching designed pressure. In addition, the system can realize three fuel supply modes of pure hydrogen, other pure fuels and mixed hydrogen through controlling spraying pulse widths of hydrogen and other fuel nozzles; and the hydrogen ratio in the hydrogen mixing mode can be adjusted to realize efficient and clean operation of the whole vehicle.

Description

technical field [0001] The invention provides a device and method for a plug-in hydrogen hybrid fuel vehicle, and the specific content relates to the technology of internal combustion engine fuel control and hydrogen on-vehicle production. Background technique [0002] Traditional vehicles powered by gasoline engines and other engines generally have problems of high fuel consumption and harmful emissions. Therefore, energy saving and emission reduction have become an important direction of automobile development. One of the important reasons for the high fuel consumption and high emissions of traditional fossil fuel engines is that the single combustion and physicochemical properties of the fuel itself are difficult to adapt to the complex and changeable engine operating conditions. Compared with fossil fuels such as gasoline, hydrogen has the characteristics of low ignition energy, fast flame propagation, wide lean burn limit and no carbon in molecular structure. This enab...
