The objective of this paper is to meet the requirements of higher torque values at all engine speeds. This can be achieved by varying the valve timing automatically using a new variable valve timing system (VVT), which gives continuously variable valve actuation at all engine speeds. A model engine is designed using dimensional analysis methods and then implemented to verify the proposed control system. Moreover, microcontroller and computeraided control systems are constructed and used to modify the variable valve timing control in the laboratory. In this paper, a mathematical model of variable valve timing is developed to obtain the best volumetric efficiency with optimum valve timing at different engine speeds. From this model, the look-up table is created at all ranges of the engine speed. A single cylinder engine is used to estimate engine performance characteristics for conventional camshaft. In addition, a model engine is designed and constructed to apply the Variable Valve Timing control system. The investigations show that the system is flexible throughout the entire range of operation speeds and is able to alter valve timing concerning both valve opening and closing. The ability of valve opening and closing can be realized with rates higher than these of the conventional timing mechanisms.
本文的目标是在所有发动机转速下满足更高扭矩值的要求。这可以通过使用一种新的可变气门正时系统(VVT)自动改变气门正时来实现,该系统可以在所有发动机转速下实现连续可变气门驱动。利用量纲分析方法设计了发动机模型,并对所提出的控制系统进行了验证。此外,构建了微控制器和计算机辅助控制系统,并在实验室中对可变气门正时控制进行了修改。本文建立了可变配气正时的数学模型,以在不同发动机转速下获得最佳配气正时的最佳容积效率。从这个模型,查找表是创建在所有范围的发动机转速。以单缸发动机为研究对象,对传统凸轮轴发动机的性能特性进行了评估。此外,还设计并构造了应用可变配气正时控制系统的发动机模型。调查表明,该系统在整个操作速度范围内都是灵活的,并且能够改变阀门开启和关闭的时间。与传统的定时机构相比,该机构能够以更高的速度实现阀门的开启和关闭。

Friction-Induced noise & vibration problem, such as Squeak & Rattle, belt noise and brake noise, has been one of most challenging technical problems faced by automotive industry. For instance, in North America, up to one 100 million dollars every year are spent on noise and vibration issues in warranty work of automotive brake systems [1,2]. The prediction and control of friction-induced noise and vibrations have been considered as an elusive problem. In this article, the friction-induced noise and vibration problem is reviewed by using brake noise as an example. The time-varying, strong nonlinear and stochastic nature of the problem is emphasized. The new perspective of diagnosis and prognosis are proposed to address this problem. The framework of diagnosis and prognosis could be developed by using nonlinear signal processing, phase space reconstruction, nonlinear stochastic system identification, and statistical pattern recognition, which effectively and efficiently helps identify system, validate numerical model, predict troublesome event occurrence and estimate uncertainty.
摩擦噪声与振动问题是汽车工业面临的最具挑战性的技术问题之一,如吱吱声、嘎嘎声、皮带噪声和刹车噪声。例如,在北美,在汽车制动系统的保修工作中,每年花费在噪声和振动问题上的费用高达1亿美元[1,2]。摩擦噪声和振动的预测与控制一直被认为是一个难以解决的问题。本文以制动噪声为例,综述了摩擦噪声与振动问题。强调了该问题的时变、强非线性和随机性质。为解决这一问题,本文提出了诊断和预后的新视角。将非线性信号处理、相空间重构、非线性随机系统辨识和统计模式识别等技术应用于系统的诊断与预测,可以有效地识别系统、验证数值模型、预测麻烦事件的发生和估计不确定性。

This paper discusses the design, modeling, and development of small motorcycle equipped with a HCCI engine in an series hybrid configuration. A mathematical model was developed using MATLAB/Simulink and used to size the powertrain components and to predict fuel economy. A conventional 125 cc spark ignition engine was modified to run in HCCI combustion mode and integrated into a prototype vehicle. Dual-fuel and external EGR strategies were used to upgrade the engine speed and torque capabilities of the engine to meet the requirements of the powertrain. An electrical generator, hub-motor, battery pack and other power electronics devices were used to form the electrical system for the vehicle. The advantages of the proposed design compared to the original motorcycle with SI engine and CVT transmission are: 1) a reduction in noxious emissions due to the HCCI combustion, and 2) higher fuel economy in city driving because of the HCCI engine and series hybrid powertrain. Fuel economy was measured by driving the motorcycle on a chassis dynamometer using a sequence of ECE-40 driving cycles. The overall fuel economy was measured to be 73.7km/L which represents a 139.3% increase in fuel economy over the baseline vehicle.
本文讨论了一种串联混合动力配置的HCCI发动机小型摩托车的设计、建模和开发。利用MATLAB/Simulink建立了数学模型,用于确定动力总成部件的尺寸和预测燃油经济性。将传统的125cc火花点火发动机改装为HCCI燃烧模式,并集成到原型车上。采用双燃料和外置EGR策略,提升发动机转速和扭矩能力,满足动力系统的要求。发电机、轮毂电机、电池组和其他电力电子设备被用来构成车辆的电气系统。与原来的SI发动机和CVT变速器的摩托车相比,该设计的优点是:1)减少了由于HCCI燃烧而产生的有害排放;2)由于HCCI发动机和串联混合动力系统,在城市驾驶中具有更高的燃油经济性。燃油经济性是通过在底盘测功机上使用ECE-40驾驶循环序列来测量的。总体燃油经济性为73.7km/L,与基准车辆相比,燃油经济性提高了139.3%。

There are three basic processes involved in sensor measurements. The senor “data acquisition” process is about converting the measured physical variables into the electrical quantities such as resistance, capacitance, or inductance through properties of special materials like a diaphragm or metallic wire. The sensor “data manipulation” process uses the converted electrical quantity to generate the corresponding electrical voltage (or current) for representing the sensor measurement. The final process is the sensor “data transmission” in which the sensor measurement represented by the output voltage (or current) is to be physically sent to the control room that might be away from the location of the senor measurement.
传感器测量有三个基本过程。传感器“数据采集”过程是将测量到的物理变量转换成电的量,如电阻,电容,或电感通过特殊材料的特性,如隔膜或金属线。传感器“数据操作”过程使用转换后的电量来产生相应的电压(或电流),以表示传感器的测量结果。最后一个过程是传感器“数据传输”,在这个过程中,由输出电压(或电流)表示的传感器测量值将被物理地发送到可能远离传感器测量位置的控制室。

Development and economic growth throughout the world will result in increased demand for energy. Currently almost 90% of the total world energy demand is met utilizing fossil fuels [1]. Petroleum and other liquid fuels include 37% of the total fossil reserves consumed for transportation and other industrial processes [1]. Emission of harmful gases in the form of nitrogen oxides, sulphur oxides and mercury are the major concerns from the combustion of conventional energy sources. In addition to these pollutants, huge amount of carbon dioxide is liberated into the atmosphere. Carbon dioxide is one of the green house gases which cause global warming. Though technology is being developed to sequester the CO2 from stationary power generating sources, it is difficult to implement such a technology in non-stationary automobile IC engines.
世界各地的发展和经济增长将导致对能源的需求增加。目前,全球近90%的能源需求是通过化石燃料来满足的[1]。石油和其他液体燃料占运输和其他工业过程消耗的化石总储量的37%[1]。氮氧化物、硫氧化物和汞等有害气体的排放是传统能源燃烧的主要问题。除了这些污染物,大量的二氧化碳被释放到大气中。二氧化碳是导致全球变暖的温室气体之一。虽然目前正在开发从固定发电源中隔离二氧化碳的技术,但在非固定的汽车IC发动机中实施这种技术是困难的。

The main aim of this paper is to study the potential impacts in hybrid and full electrical vehicles performance by utilising continuously variable transmissions. This is achieved by two stages. First, for Electrical Vehicles (EVs), modelling and analysing the powertrain of a generic electric vehicle is developed using Matlab/Simulink-QSS Toolkit, with and without a transmission system of varying levels of complexity. Predicted results are compared for a typical electrical vehicle in three cases: without a gearbox, with a Continuously Variable Transmission (CVT), and with a conventional stepped gearbox. Second, for Hybrid Electrical Vehicles (HEVs), a twin epicyclic power split transmission model is used. Computer programmes for the analysis of epicyclic transmission based on a matrix method are developed and used. Two vehicle models are built-up; namely: traditional ICE vehicle, and HEV with a twin epicyclic gearbox. Predictions for both stages are made over the New European Driving Cycle (NEDC).The simulations show that the twin epicyclic offers substantial improvements of reduction in energy consumption in HEVs. The results also show that it is possible to improve overall performance and energy consumption levels using a continuously variable ratio gearbox in EVs.
本文的主要目的是研究使用无级变速变速器对混合动力和全电动汽车性能的潜在影响。这是通过两个阶段实现的。首先,对于电动汽车(ev),使用Matlab/Simulink-QSS工具包对通用电动汽车的动力系统进行建模和分析,包括不同复杂程度的传动系统和不含传动系统。对一辆典型电动汽车的预测结果进行了三种情况的比较:无变速箱、无级变速器(CVT)和传统的阶梯变速箱。其次,对于混合动力汽车(hev),采用双周转功率分流传动模型。基于矩阵法的周转传动分析的计算机程序被开发和使用。构建了两种车型;即:传统的ICE车辆,以及带有双周转齿轮箱的HEV。这两个阶段的预测都是在新欧洲驾驶循环(NEDC)中进行的。仿真结果表明,双星环对混合动力汽车的节能效果有显著改善。结果还表明,在电动汽车中使用无级变速变速器可以提高整体性能和能耗水平。

This paper introduces a gearless hydraulic transmission system that provides an infinite speed ratio similar to a Continuous Variable Transmission (CVT) with energy storage capabilities. The transmission system is modeled in various operating conditions such as all-electric and gasoline configurations. A Rate Limited (RL) controller is designed to control the vehicle traction forces. A PI controller is designed to regulate the charge and discharge power through storage and range extender engine in different driving conditions. The results demonstrate high performance operation of the transmission system in standardized drive cycles. The results show that the control system provides a good speed-command tracking performance.

Alternative Fuels and Renewable Energy Strategies in the Energy Revolution 能源革命中的替代燃料和可再生能源战略
Pub Date : 2013-01-01 DOI: 10.4172/2167-7670.1000E113

The energy revolution advocates for gradual transition from fossil fuels to alternative or renewable forms of energy. The increased technological activities across the globe, the global nature of economy and increasing world population require proactive measures to meet the future world energy requirements. There is a wide spread concern for air quality and health issues associated with environmental pollution from automobiles. Every car on the road today outputs oxides of nitrogenNOx, carbon monoxide-CO, hydrocarbon-HC, particulate matter-Pm, oxides of sulfur-SOx and greenhouse gases-GHG into the atmosphere. Hydrocarbon and NOx in the presence of sunlight cause photochemical smog. While SOx and NOx in the presence of moisture form acids. All these environmental pollutants impact health, vegetation, acidicity of our surroundings and are a grave concern to the society.
能源革命倡导从化石燃料逐步过渡到替代或可再生能源形式。全球技术活动的增加、经济的全球化性质和世界人口的增加要求采取积极的措施来满足未来世界的能源需求。人们普遍关注与汽车造成的环境污染有关的空气质量和健康问题。如今,路上行驶的每辆汽车都向大气中排放氮氧化物(nox)、一氧化碳(co)、碳氢化合物(hc)、颗粒物(pm)、硫氧化物(sox)和温室气体(ghg)。碳氢化合物和氮氧化物在阳光下产生光化学烟雾。而SOx和NOx在水分存在下形成酸。所有这些环境污染物影响健康、植被、我们周围环境的酸度,是一个严重关注的社会问题。
