一、冷车启动对油耗及磨损的影响为了降低发动机冷启动时的耗油和磨损,启动前要预热升温(用90～95℃热水经自制三通管直接灌入气缸体水套中,使其完全充满后再流入散热器,灌排数次,使温度达到30～40℃以上)和冷摇慢转(旋转曲轴10～20转,使机油变稀泵入各润滑面,以减少启动时的磨擦阻力),并怠速运转至发动 First, the impact of cold start on fuel consumption and wear To reduce fuel consumption and wear when the engine starts cold, warm-up before the start of warming (with 90 ~ 95 ℃ hot water through the homemade tee directly into the cylinder body water jacket , So that it is completely full and then into the radiator, irrigation and drainage several times, the temperature reached 30 ~ 40 ℃ above) and cold slow rotation (rotating crankshaft 10 to 20 rpm, the oil thinning into the lubrication surface to reduce Friction resistance when starting), and idling to start
