启动发动机

This paper presents a new model describing the autoignition of pilot diesel in the mixture of methane with air for dual fuel engines.

预测发动机的燃烧启动和敲缸都需要研究发动机的着火过程以及开发发动机的着火模型。

In the early days of cars, you actually had to crank the engine with a little handle. Now the cranking motor or starter is just powerful enough to start the engine turning.

以前的汽车需使摇柄才能使发动机启动，现在启动机或点火机已足以使发动机启动了。

At first, with the low-frequency data measured, three of the LRE fault detection systems for the real-time condition are proposed using the nonlinear identification technology of the BP neural network, the state estimation technology of the dynamic neural network, and the pattern recognition technology of the fuzzy hypersphere neural network. The learning algorithms of the BP and dynamic neural network are researched at the same time. Furthermore, while the engine operation is divided into the start and steady-state processes, the real time ability, the response time, the accuracy, the robustness, the sensitivity and the monitoring parameter optimization are studied. In the test data analyses of the YF-75 engine, the detection system correctly carried out for all normal tests, and in the three abnormal tests the engine faults were accurately forecasted.

首先，基于低频测量数据，采用BP神经网络的非线性辨识技术、动态神经网络的状态估计技术及模糊超球神经网络的模式识别技术，提出了三种发动机故障实时检测系统；同时研究了BP神经网络和动态神经网络的学习算法；另外还把发动机工作分为启动过程和稳态过程，分别讨论了神经网络故障检测系统的实时性、及时性、准确性、鲁棒性、敏感性及参数优化问题；在YF-75发动机试车数据分析中，不仅全部正确地监测了正常试车过程，而且准确地预报了三次异常试车中的发动机故障。

These results clearly justifies that in combustor, the injector location and its conditions have no effect on the flowfield structure but have strong effect on the combustion efficiency, and that inside the engine, undesirable injector conditions can result in the engine thermal choked and unstart.

第五章计算了含横向喷流的二维燃烧室和一种简化一体化超燃冲压发动机流场，发现在燃烧室中喷口位置及喷射条件对流场的结构影响不大，但对燃烧效率却有较大的影响；而在发动机内部，不适当的喷射条件，有可能引起发动机的&热壅塞&，使发动机无法启动。

Analysts believe that the signs may be in the description, some of China's economic growth is beginning to re-start the engine.

分析家认为，迹象表明可能会在描述中，一些中国的经济增长已开始重新启动发动机。

Failure phenomenon: mechanic report: a 125-type scooters (GY6 engines), it is difficult to start the engine cold, start to work within a few minutes after the operation is not smooth, but the engine JJM1 Pressure Gauge Valve thermal working well, start easily.

故障现象：修理工反映：一辆125型踏板车（GY6发动机），发动机冷态很难启动，启动后开始工作的几分钟内运转不平稳，但发动机热态工作良好、启动容易。

Use methods: This product is used with special cleaning equipment (3405). Start engine and link vacuum pipes.

使用方法：将本品配合清洗设备（3405），启动发动机，连接真空管。

Remove the air filter, start the engine, in the idle state, the amount of spray holes within the carburetor, pipes, valves.

卸下空气滤清器，启动发动机，在怠速状态下喷洗化油器内各量孔、喉管、阀片。

Troubleshooting: According to the mechanic to reflect the phenomenon of the car and the car carburetor set JJM8 Pressure Gauge Valve the "automatic start-enriched electric device" the characteristics of analysis, the causes of the car is cold engine starts automatically when the electric-type plus thick needle device can not be opened, so that combustible mixture can not add thick, can not meet the needs of the engine cold start.

故障分析与排除：根据修理工反映该车的现象与该车化油器上设置有&电热式自动启动加浓装置&的特点分析认为，该车故障的原因是发动机冷态时电热式自动启动加浓装置的针阀不能开启，使可燃混合气不能加浓，不能适应发动机冷态启动需要。
