51651.全球汽车感应式无线充电系统市场报告（2014-2018年）
[汽车制造业,电气机械和器材制造业,电力、热力、燃气及水生产和供应业] [2015-01-12]
Electric vehicles are gaining importance because of the rising global fuel prices and the alarming levels of air pollution. There is widespread concern over the negative effects of global warming. In such a scenario, the rapid adoption of electric vehicles is seen as the most viable solution. Earlier, the time taken to charge electric vehicles was one of the major concerns, but with the advent of wireless inductive charging, this issue has been resolved. Inductive wireless charging is considered as a major breakthrough because it has made the use of plugs and cords redundant. Inductive charging takes place when an electromagnetic field transfers energy between two coils.

51654.全球婴儿汽车座椅市场报告（2015-2019年）
[汽车制造业] [2015-01-05]
Baby car seats ensure the safety of babies during travel. There are different types of baby car seats depending on the weight and age of a child. The seat increases the safety of a baby in case of accidents and is made of foam padding, fabric covers, and a harness. It should be at the correct angle so the baby's head does not fall forward. It should not be used for more than 6 years, and should be periodically examined by the manufacturers.

51656.全球汽车机油滤清器市场报告（2015-2019年）
[专用设备制造业,汽车制造业,仪器仪表制造业] [2015-01-04]
An automotive oil filter is a device designed to remove impurities and undesired components from circulating engine oil in a vehicle. Engine oil lubricates engines, and it needs to be freed from particles that may increase friction against piston movement and reduce engine efficiency. Canister-type filters are the most commonly used automotive oil filters.

51657.全球汽车HVAC市场报告（2015-2019年）
[汽车制造业] [2015-01-04]
HVAC is the technology used to provide heating, ventilation, and air conditioning to maintain good air quality and deliver thermal comfort through adequate ventilation inside vehicles. The main principles behind the operation of an HVAC unit are conduction and convention. Heat is transferred from a low-temperature region to high-temperature region inside the vehicle because of pressure difference.

51658.全球汽车废气再循环EGR系统市场报告（2015-2019年）
[计算机、通信和其他电子设备制造业,仪器仪表制造业,汽车制造业,信息传输、软件和信息技术服务业,专用设备制造业] [2015-01-04]
An EGR system helps recirculate gases from the exhaust system in an automotive engine. The EGR system valve opens when it encounters pressure from a vehicle's exhaust and sends back the exhaust gas into the combustion chamber. The primary function of an EGR system is to reduce the combustion temperature of the fuel in an automotive engine, and thus reduce production of NOx during engine operation. In gasoline engines, the EGR system also reduces fuel consumption by de-throttling the engine at partial load. At present, the adoption of EGR systems has increased because of stringent government regulations regarding the emission of harmful gases, such as NOx, and PM.

51660.基于小波包和BP神经网络的柴油机故障分析
[汽车制造业] [2014-12-29]
随着人们对柴油机动力性、经济性要求的不断提高,现代柴油机结构日趋复杂,对其故障诊断要求也越来越高。本文通过WP7柴油机台架试验,模拟供油提前角、供油量、气门间隙以及喷油压力异常四种故障,采集振动信号,利用小波包技术对各种故障振动信号特征参数变化规律进行了分析,比较了各频率对故障信息敏感度的影响,进而利用MATLAB建立BP神经网络,对提取的信号特征进行训练与测试,并进行验证,实现了对柴油机的故障诊断。
