Design of Air Intelligent Air Intake and Fuel Constant Temperature System for the Explosion-Proof Diesel Engine

The usage rate of explosion proof diesel engine trackless rubber wheel vehicle is relatively high in coal mines in Shaanxi and Inner Mongolia region. However, in the cold winter, vehicles often fail to start when parked outdoors. Even if the vehicle is difficult to drive, the low temperature of the engine block can cause problems such as black smoke from explosion-proof diesel engines. Based on intelligent detection and electronic control technology, taking the ambient temperature of -25 °C in the northwest region as a design basis, an intelligent intake fuel constant temperature system for explosion-proof diesel engines was designed. The working principle of the system, the design and selection of each subsystem were described, and the intelligent control function of good cold start performance of flameproof diesel railless rubber tired vehicles was achieved, greatly improving the universality of the vehicle in cold working conditions and reducing the complexity of vehicle maintenance.
