天然气汽车使用中存在的问题及对策

Problem and Countermeasure of Natural Gas Vehicle in Use

阐述了天然气汽车功率下降和早期磨损的原因。介绍了提高天然气汽车功率的措施，即提高发动机的充气系数，适当提高发动机的压缩比及使用专用天然气汽车发动机润滑油。试验表明，使用专用发动机润滑油对提高发动机功率和防止早期磨损具有显著效果。

The causes involved in power decrease and early wear of natural gas vehicle are described in this paper.The measures to increase power of natural gas vehicle,i.e. increasing the air charge coefficient of engine,increasing accordingly the engine compression ratio,using a special engine lubrication oil of natural gas vehicle are described as well.It is shown by test that using a special engine lubrication oil has its significant effect to increase engine power and prevent engine from early wearing.
