1.发动机水温应保持在85-95℃。这段水温热效率最高,耗油量最小。2.避免发动机空转或怠速动转。如停车5分钟以上应熄火。3.尽量在满负荷状态下工作。如负荷不足,应采用高档小油门运转。避免超负荷作业。4.排气管不要任意接长或改变方向,以免增加排气阻力。5.杜绝燃油滴漏,定期对发动机测试耗油 1. Engine water temperature should be maintained at 85-95 ℃. This section of the highest thermal efficiency of water, fuel consumption minimum. 2. Avoid engine idling or idling. Such as parking for more than 5 minutes should be turned off. 3. Try to work at full capacity. Such as lack of load, should be high-end small throttle operation. Avoid overload work. 4. Exhaust pipe do not pick any length or change direction, so as not to increase the exhaust resistance. 5. To eliminate fuel drip, fuel consumption on a regular basis for the engine test
