Abstract: As the core power device of explosion-proof trackless rubber-tyred vehicle vehicle, the performance of explosion-proof diesel engine determines the dynamic performance and emission performance of the vehicle. The advanced explosion-proof electronic fuel system of the explosion-proof electronic control diesel engine can realize precise timing quantitative injection, the maximum injection pressure can reach 130 MPa. Integrated with the methane sensor, surface temperature sensor and other coal mine special requirements, reduce the diesel engine electrical protection system, reduce the complexity of the machine. To meet the requirements of coal mine explosion-proof, the emission performance of explosion-proof diesel engine is greatly improved to ensure the safe and clean production environment of coal mine.
