| 1. | Study on combustion pressure oscillation in vehicle diesel engines
车用直喷式柴油机燃烧压力振荡控制的研究 |
| 2. | Maximum combustion pressure
最大燃烧压力 |
| 3. | Tests include sensitive test , test of emissions , oil consuming test , and combustion pressure curve test
试验包括敏感性试验、排放测试试验、油耗试验及燃烧压力曲线测试试验。 |
| 4. | Assume combustion pressure as pulse force , the kurtosisness of torsional vibration of diesel is steady when engine is " healthy "
在正常发火情况下，扭振信号的峭度不一定按照正态分布，但是对特定的柴油机装置是稳定的。 |
| 5. | The combustion pressures of each cylinder were measured continuously and simultaneously of the engine 492qc burning gasoline and cng
使用本采集系统，还连续采集了492qc发动机燃烧汽油和压缩天然气( cng )时不同工况的各缸压力。 |
| 6. | This idea rooted in the supposal that combustion pressure is a pulse force and the characters that wavform parameters are sensitive to pulse
这思路来源于将柴油机作功冲程的爆发力近似看成一个脉冲激励的假设，以及波形参数对脉冲激励敏感的特点。 |
| 7. | 3 . a method to convert the torsional vibration into individual cylinder combustion pressure using ims adaptive algorithm is putted forward . the position of misfire cylinder can pointed immediately using this method
熄火故障主要表现在作功冲程和正常情况不同，利用扭振信号辨识作功冲程压力大小，不仅能够诊断熄火缸的位置还能纵观各个气缸的作功情况。 |
| 8. | A parametric study of the effect of variation in injection timing is then carried out . both the simulation results and experimental data show that deferred injection timing leads to decreases in combustion pressure and nox concentration
模拟结果和实验结果都表明，推迟喷油，可以减少预混燃烧所占的比例，降低最大燃烧压力，从而减少直喷式柴油机的no _ x排放。 |
| 9. | And the heat of condensation phase reaction was determined by dsc experiment . the experimental results indicate that the formulae of high content fine ap and coated boron with 20 % ap is of a stable combustion in the air , while having a rate of 2 . 94 mm / s under the combustion pressure of 0 . 5 m pa
结果表明：调整ap级配使细粒ap含量增加和用20 ap包覆硼的配方，燃烧稳定，残杂分散性好，燃速在低压( 0 . 5mpa )下为2 . 94mm s 。 |
| 10. | The repeating experiments show this kind of emulsified diesel oil can reduce fuel consumption by at least 10 percent , smoke density and nox emission by more than 40 percent . and the exhaust temperature and the maximum combustion pressure also decrease . la addition , the experiments about emulsified heavy oil and emulsified mixture of heavy oil and diesel oil are done on 1135 diesel engine
经反复试验表明该型乳化油与0 ~ #柴油相比平均节油率不低于10 ，主要排放物nox 、碳烟降低40以上，同时排温和最高燃烧压力降低，另外，在1135柴油机上进行了乳化重油和乳化重油与柴油混合物的试验，结果表明燃油耗率和so _ 2排放均显著降低。 |
