So ,the temperature is quite essential for an engine to produce power .No engines can work well without suitable operating temperatures .If the engine runs too hot ,it may suffer form pre-ignition,while the air-fuel change is ignited prematurely from excessive combustion chamber temperature.Viscosity of the oil circulating in an over heating engine is reduced.Hot oil also forms varnish and carbon deposits may be drawn into the combustion chamber where it increases HC emission.This also causes poor performance and premature wear ,and may even result in engine damage.What is more,the behavior of the metals at excessively high temperature also differs from that at normal temperatures and can produce a condition in which the metal deforms slowly and continuously at a constant stress,If the engine runs too cold, the fuel will not vaporize properly.If liquid fuel reachees the cylinders,it will reduce lubrication by washing the oil from the cylinder walls and diluting the engin oil.This causes a loss ofperformance, an inrease in HC emissions, and premature engine wear.

所以，温度是很有必要的引擎来产生电力，没有引擎，可以工作，如果没有合适的操作温度，如果发动机运行太热，它可能遭受的形式预点火，而空气燃料的改变是点火过早过量燃烧室temperature.viscosity的石油流通的过度加热发动机是reduced.hot油价也构成了清漆和碳存款可能会被拖入燃烧室而增加hc的emission.this也造成业绩不佳和过早磨损，甚至可能导致发动机damage.what更重要的是，行为的研究金属在过高的温度也有不同，在正常温度下，可以达到的一个条件，其中金属变形速度缓慢，不断在恒应力，如果发动机运行太冷了，燃料价格将不会汽化properly.if液体燃料reachees气瓶，将减少润滑洗油从气缸壁和稀释器oil.this造成损失ofperformance ， inrease在hc排放，发动机过早磨损。

研究结果显示，透过政府之补贴可提高公车业者使用燃料电池公车之意愿，至2021年左右，燃料电池公车相对於燃油公车已具有相当程度之竞争力；此外，公车业者未来使用量愈多，空气污染之减量成效愈彰，能源节约效益亦随之愈大；在多次绩效补贴方面，补贴额逐年减少，且越晚采用补贴次数越少，至2021年左右，因燃料电池公车系统之总成本低於燃油公车系统总成本，故自该年起可停止实施绩效补贴；在外部成本改善之效益方面，改善空气污染之绩效补贴初期较不具效益，但透过政府部门相关之补贴机制，其成本效益将逐渐彰显。

The results indicated that BaCe0.8Ho0.2O(subscript 3-α) sinters are of single-phase structures of orthorhombic perovskite.
