AI Technical Summary
Technical Problem
Existing parking heaters cannot automatically adjust the fuel injection amount according to the external environment, resulting in incomplete fuel combustion and increased pollutant emissions.
Method used
By installing an oxygen sensor and a solenoid valve in the parking heater, the oxygen sensor detects the excess air coefficient and environmental parameters, and controls the opening of the solenoid valve to dynamically adjust the fuel injection quantity, thereby achieving adaptive control of the fuel injection quantity.
Benefits of technology
It improves fuel combustion efficiency, reduces pollutant emissions, and ensures the efficient operation of the parking heater under different environmental conditions.

Abstract
This invention discloses a control method, apparatus, device, and storage medium for a parking heater. The control method includes: acquiring altitude, ambient temperature, and excess air coefficient; controlling the opening of a solenoid valve based on altitude and ambient temperature to control fuel injection quantity when the oxygen sensor is disabled; and controlling the opening of the solenoid valve based on the excess air coefficient to control fuel injection quantity when the oxygen sensor is enabled. The technical solution of this invention dynamically adjusts the fuel injection flow rate in the parking heater through a controller, controlling the solenoid valve opening based on altitude and ambient temperature when the oxygen sensor is disabled, and controlling the solenoid valve opening based on the excess air coefficient when the oxygen sensor is enabled. This improves the accuracy of adaptive fuel control in the parking heater, ensures combustion efficiency, and reduces pollutant emissions.
