Abstract

The invention discloses a novel engine system and an injection pulse width correction method. The novel engine system comprises a cylinder body, an electronic control unit and a supply system, wherein the supply system is connected to the cylinder body, and the electronic control unit is respectively connected to the cylinder body and the supply system; the supply system comprises a fuel tank, a fuel system and a hydrogen production system, one end of the fuel system and one end of the hydrogen production system are connected to the fuel tank, and the other end of the fuel system and the other end of the hydrogen production system are connected to the cylinder body; and the cylinder body is provided with a gas inlet end and a gas outlet end, and the gas inlet end and the gas outlet end are respectively connected to the cylinder body. By adopting the technical scheme, the supply system comprises the fuel tank, the fuel system and the hydrogen production system, one end of the fuel system and one end of the hydrogen production system are respectively connected to the fuel tank, and the other end of the fuel system and the other end of the hydrogen production system are respectively connected to the cylinder body, so that the pulse width can be adjusted in real time, the engine thermal efficiency is improved, the cold start characteristic is improved, and the combustion effect is improved.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an engine system and an injection pulse width correction method. Background technique [0002] The shortage of petroleum resources is a major issue facing the sustainable development of my country's economy today. The fuel for automobiles in my country is mainly gasoline and petroleum. The proportion of fuel oil is increasing day by day, the shortage of oil resources in my country and the air pollution caused by automobile exhaust are also becoming more and more prominent; there are also methanol engines, but the lower limit of ignition of methanol engines is high, the steam pressure is low, the cold start performance is poor, and there are problems such as formaldehyde and unburned methanol. unconventional emissions. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a novel engine system and injection pulse width correc...
