engine endurance
engine life
Examples
- Reduce the wearing and tearing , save the maintenance cost , lengthen the life - span of the engine
减少磨损，节约维修费用，延长发动机寿命。 - They had only a lifetime of about 10 flying hours and production never reached the output necessary
其发动机寿命只有大约10个飞行小时，而且从未达到过。 - Standard test method for motor life evaluation of a canister , hand - held , stick , and utility type vacuum cleaner without a driven agitator
不带驱动搅拌装置的罐式手持通用真空吸尘器发动机寿命评定的试验方法 - Have excellent lubrication nature , form the lubricated membrane of the high strength in high speed operation , guarantee to lubricate the result , lengthen the life - span of the engine
具有优异的润滑性，在高速运行时形成高强度的润滑膜，确保润滑效果，延长发动机寿命。 - The disposal of the valves and intake manifold structure not only affect fresh air charge but airflow in the cylinder , which immediately affect combustion efficiency and the performance of dynamic , economic and emission . the structure of the air distributing institution has influence on charging efficiency and the noise of engine . the combustion chamber affects compression scale which has great influence on dynamical performance ; f / v which affects the exhaust of hc ; squash area and clearance which have great influence on the intensity of squash
气缸盖的气门排列方式与气道结构形式影响进气充量和气流在气缸内的运动，从而影响了燃烧效率，对整机的动力性、经济性以及排放都有直接的影响；配气机构的形式影响充气系数和整机噪声等；缸盖燃烧室决定了影响整机动力性能的压缩比，影响hc排放的f / v和对挤流起决定性作用的挤气面积以及挤气间隙，所以燃烧室对整机动力性、经济性、排放等都有重要的影响；气缸盖是整机热负荷与热应力最大的部件之一，热负荷过高将不利于发动机寿命以及可靠性的提高。
