1、该机采用重庆康明斯符合非道路机械国II排放发动机，输出扭矩大，油耗低，使用可靠，节能环保。
2、采用单级单相三元件液力变矩器，不停车换挡，提高作业效率。
3、采用上海芬创空气滤清器及预滤器装置；延长发动机寿命，增大保养间隔时间。
4、发动机消音器取消引射装置，增大排气通径，减少了排气压力，进而减少了燃油消耗。
5、液压滤清器增加报警装置，及时提醒用户清理滤芯或更换液压油。
6、空调冷却器布置在发动机罩的下方，可以借助发动机冷却气流进行冷却，增加了冷却效果。
7、油、水等日常保养点人性化布置，检查维修方便。
8、整机采用先进的液力传动，液压操纵技术，结构合理，操纵轻便灵活，质量可靠。
1、The YD320 crawler bulldozer is equipped with Chongqing Cummins engine which conforms to National II emission standard for road machinery, and features large output torque, low fuel consumption, energy efficient, and environmental friendliness.
2、Equipped with a single-stage, single-phase, and three-element hydraulic torque converter, the equipment can achieve gear shifting without stopping. This largely increases operation efficiency.
3、The Shanghai Fenchuang air filter and prefilter effectively extends the engine's service life, and increases the maintenance interval.
4、The engine muffler which eliminates the design of ejector is provided with increased exhaust path, and reduced exhaust pressure. This helps reduce fuel consumption.
5、The alarming device for the hydraulic filter can timely remind users to clean the filter or exchange the hydraulic oil.
6、Positioned below the engine hood, the air conditioner condenser provides the air conditioner with increased cooling effect, as it can make use of the engine's cooling air.
7、The crawler bulldozer features convenient maintenance, due to its user-friendly designed oil level and water level check system, as well as other parts needing daily maintenance.
8、The equipment adopts advanced hydraulic transmission and hydraulic control technologies. With rational structure, it is flexible in control.
