方牌®机油滤清器的设计理念“方牌”机油滤清器的产品设计是基于“滤清器应该用来防止各种有害杂质从而达到保护发动机远离磨损的要求”这一理念展开的。衡量这一效果的最佳工具就是“单次通过率”和“多次通过率”的试验。同时,整体设计的原则还必须体现较高的过滤效率和较长的使用寿命之间的平衡。 Our design of an oil filter is based on the premise that the filter is present to remove harmful particles and thus protect the engine from wear. To measure this property single pass efficiency or multipass tests are the best tools. The total design, however, must balance high efficiency with long life. 单次或多次通过率指标的提升可以有效减少引擎磨损。相对于一个过滤能力只针对40微米颗粒的滤清器,可过滤30微米颗粒的滤清器可减少引擎磨损高达50%。同样的,一个15微米过滤效果的滤清器可减少引擎磨损达70%。 “Abrasive engine wear can be substantially reduced with an increase in filter SPE(MP). Compared to a 40 micron filter, engine wear was reduced by 50% with 30 micron filtration.” (98% point) “Likewise, wear was reduced by 70% with 15 micron filtration.” (SAE TPS 881825 p5 -David R. Staley, GeneralMotors Corp. 1988)
机油滤清器的理想更换间隔–FRAM的工程师们建议您每行驶5,000英里(或7,000公里)的时候,同时更换您爱车的机油和机油滤清器。 –如果车辆是带涡轮增压的发动机或者常常在严苛的工作条件下运行,应适当增加更换频次。 –您也可以参照车辆制造商的建议确定更换间隔。 |
