In this article,with the voltage between the probes of a spark plug,ionization currents with different knock intensities of the engine are measured successfully in the experiments on a DA462-A four-cylinder gasoline engine.According to the character of the ionization current four indexes are chosen to analysis the obtained data.It is clear that the resultants by the calculation of ionic current are different with different knock intensities of the engine.

通过在火花塞电极两端加偏置电压的方法，在DA462-A型4缸汽油机的台架试验中，成功地检测出汽油机在不同爆震强度时的离子电流信号，并根据离子电流信号的特征选用了4种爆震强度评价指标，经分析计算表明各工况爆震强度的合理递进顺序。

As a result, by merely replacing the gasoline injector with natural gas injector, a large volume of natural gas is injected on the intake valve and then reflected, which makes the fuel concentration and pressure field in the intake manifold after the natural gas injection for the natural gas engine differ greatly from those for gasoline engine.

结果表明，若仅把MPI汽油机的喷油器用天然气喷射阀更换，大量的天然气喷到进气阀后反射，造成天然气发动机进气岐管内的燃料浓度场、压力场与MPI汽油机明显不同；并且进气阀被打开后，先期吸入气缸的天然气在纵向滚流的作用下被挤向进气阀底部下方，与后期吸入气缸的空气形成明显的分层充气构造。

Based 188F gasoline engine heat load studies, the research unit based on Using AutoCAD software for the design cylinder sleeve, and then use the software PRO-E 3D modeling, and the calculated and experimental analysis to determine the reference cylinder heat transfer across borders, reuse finite element analysis software ANSYS right cylinder mathematical analysis, systematically on the finite element method in 188F cylinder gasoline engine design of the application, in-depth study of the thermal load on the performance and reliability, as relates to structural strength, stiffness, temperature and so on.

本文以188F汽油机热负荷为研究对象，在研究整机的基础上，利用AUTOCAD软件进行汽缸套的设计，然后用PRO-E软件进行三维建模，并通过计算解析和实验参考确定了气缸套各处的传热边界条件，再利用有限元分析软件ANSYS对气缸套进行数学分析，系统地探讨了有限元法在188F汽油机缸套设计中的应用，深入研究了其热负荷对性能和可靠性的影响，内容涉及到结构强度、刚度、温度场等方面。

The result shows that under the engine condition of high speed and high load,an enough amount of secondary air greatly reduces the emission concentrations of CO and HC,and under the engine condition of med.

在车用汽油机排气中CO和HC生成与热反应净化机理研究的基础上，通过试验探讨了二次空气对提高车用汽油机排气热反应净化效果的影响。

The test shows when the gasoline engine parameters remain unchanged, the higher volume grade of alcohol, the stronger the engine power will have; the larger fuel consumption, the lower gasoline engine NOx and CO will discharge.

结果表明，在保持汽油机参数不变的前提下，随着乙醇的体积分数的增大，汽油机的动力性提高，燃油消耗量增加，CO和NO的排放量降低，但乙醇的体积分数大于40%时HC的排放量增加明显。

However, the difference with the gasoline engine is that: gasoline engine is ignited, diesel engine is a compression ignition.

但与汽油机的不同之处在于：汽油机是点燃，柴油机是压燃。
