Description

technical field [0001] The invention belongs to the technical field of automobiles, and specifically relates to an electronically controlled oxygenation device and an oxygenation method for optimizing engine plateau starting performance. Background technique [0002] Difficulty in cold starting is currently the most serious engineering problem that plagues the application of engines. In the western region of my country, due to the high altitude, low air pressure and low air density, it is difficult or even impossible to start the construction machinery and vehicle engines used in this area. The situation of starting is more serious, thereby serious situations such as " lying down " or traffic interruption occur. [0003] It is difficult for the engine to start cold on a plateau. In addition to being affected by common factors such as low intake air temperature, low fuel temperature, and low engine coolant temperature, the engine starts at low temperature. Another main reason ...
