Lubricant quality levels low speed high load, high speed and high load conditions using CE grade diesel oil lubrication; turbocharged diesel engine should be used in CD and above; CF-4 for high-speed, heavy-duty, long-term operation of the diesel engine reducer Fans of spare parts, especially for highway driving. Effectively prevent the piston ring wear, oil thickening; selection CG-4 diesel fuel oil sulfur content is less than 0.05%; greater fuel injection pressure, higher operating temperatures bimetallic piston engines, diesel oil selected CH-4; containing " low temperature exhaust gas recirculation "system of engine deceleration oil seal parts, requires selection CI-4 diesel engine oil. Compared to the high-level and low-level oil, anti-oxidation, and other aspects of clean dispersion capability are significantly improved. In addition, the valve train wear protection, anti-grease, to prevent clogging of the filter, lubricant loss and low temperature pumpability, etc. have been significantly optimized. At present, three countries with the requirements of environmental protection, the promotion of four countries, each engine manufacturer introduced a high-quality engine (electric engine), the oil level is also a corresponding increase in the use of gear bearing spare parts, CD level already eliminated, CF, CH-class mainstream. According to China's national conditions, such as severe overloading of vehicles, poor road conditions, the driver low degree of specialization, the sulfur content of diesel fuel instability and other adverse factors, resulting in engine overhaul in advance. We should use high quality level of oil. Siemens Mechanical Drive Systems (Tianjin) Co., Ltd. formerly Flender Power Transmission (Tianjin) Co., Ltd.
