2.1.3 Main Applications and Working Environment
4D24 & 4D24T series diesel engines can be applied for agriculture & garden fields, construction equipment, power generation, marine and industrial equipment.
Engine can work properly with ambient temperature of -30°C ~ 45°C, it prohibits from running under the environment of water leaching and fire. When the ambient temperature is below -30°C or higher than 50°C or altitude over 2000 meters(1000 meters for 4D24 naturally aspirated type), please consult with our technology or service department and take effective measures or use the special engine to ensure that the engine could work properly.
