Abstract:

Currently, the most important objective in designing automobiles is to focus on environment-friendly and safety performance aspects. For the environment-friendly aspect, the issues relate to the shift towards lightweight automobile production, for improving fuel-efficiency and reducing exhaust fumes. However, in contrast, the issues of the safety performance such as crash safety, comfort level and muti-functional programs demand increase of automobile’s weight. Therefore, the design of automobile should be inclined towards the safety aspects, but at the same time, it also should consider reducing the structural weight of an automobile. In this study, for lightweight design of side member, CFRP side member was manufactured from CFRP unidirectional prepreg sheet. The stacking condition related to the energy absorption of composite materials, is being considered as an issue for the structural efficiency. Therefore, the axial collapse tests were performed with change of the stacking condition, such as fiber orientation angle and interlaminar number. The collapse modes and energy absorption characteristics were analyzed according to fiber orientation angle and interlaminar number.

Abstract:

With the growth of the economy, the number of automobiles on the road is fast growing, resulting in substantial environmental pollution from exhaust gas emissions. In the automobile factory, some improvements have been achieved by constructing devices to degrade automobile exhaust. However, although most of the vehicle exhaust emissions have met the national standards, the exhaust gas is superimposed at the same time period due to the increasing traffic volume, making the exhaust emissions seriously reduce the air quality. Therefore, the scholars in the road field began to study new road materials to degrade vehicle exhaust, which has gradually become one of the effective ways to reduce automobile exhaust. Photocatalyst materials have been widely concerned because of their ability to oxidize harmful gases by solar photocatalysis. Yet, the effect has been not satisfactory because of the small light response range of photocatalyst material, which restricts the catalytic effect. In this study, this paper attempts to use Fe3+ to modify the TiO2, which is one of the main photocatalytic materials, to expand the range of light reaction band and to improve the degradation effect of automobile exhaust. The degradation effects of ordinary TiO2 and modified TiO2 on automobile exhaust were compared by test system in the laboratory. The results show that the modified TiO2 can effectively improve the performance of vehicle exhaust degradation. Moreover, the molecular dynamics method was used to establish the channel model of TiO2, and the dynamic process of automobile exhaust diffusion and absorption was simulated. The diffusion law and adsorption process of different types of automobile exhaust gas such as NO, CO, and CO2 in the TiO2 channel were analyzed from the molecular scale through the radial concentration distribution and adsorption energy.

Abstract:

With the rapid development of China's economy and society, the domestic demand for automobiles is growing explosively. At the same time, the dependence of China's crude oil on foreign countries exceeds 65%. This is a great hidden danger to the sustainable development of China's economy and energy security. Automobile consumes a large amount of petroleum resources, and automobile exhaust is one of the main factors causing environmental pollution. In view of the dual pressure of energy saving and emission reduction, methanol has been favored by many researchers for its many advantages (such as cleanliness, environmental protection, renewable and high accessibility). In this paper, the resource extensibility of methanol, the physicochemical properties of methanol, the application characteristics of methanol in internal combustion engine and the comparison of the combustion performance of methanol with traditional fuels are summarized and analyzed.

Abstract:

In accordance with globalization, privatization etc., India is the 5th largest auto market in the world. Along with that, India ranks 3rd in carbon emission as per the data of 2020 proving, the total CO2 emission has been increased to 988.6 tonnes per year. Hence, there is a tremendous increase in air pollution. In some cities, 80% of air pollution is from automobile exhaust. Although coming is an era of e-mobility, the immediate transformation from internal combustion engine to electric vehicle seems to be hectic. This is because of many factors such as expense, charging facility, power etc. Analyzing the difficulty in the rapid face change, suitable techniques can be introduced which can purify and reduce the automobile exhaust minimizing the amount of harmful chemicals in it. The chemicals coming after EGR (Exhaust Gas Re-circulation) include CO2, SO2, NO2, CO and hydrocarbons which could generate particulate matter. These contaminants are a threat to the living beings as well as the archaeological monuments. There exists another fact that the arrival of the vehicle scrappage policy may be an unfortunate hit for the owners having vehicles older than 20 years. Due to the harmful exhaust gas, these are to be scrapped even though they have high performance at the scrapping time. Hence, this project discusses various techniques which can be employed to absorb the hazardous pollutants from the exhaust gas before releasing to the atmosphere. The project explains the various experimental methods including catalysis, honeycomb filtering, UV method etc., resulting in the design of an efficient tail gas purification system in a moving vehicle. Hence, through proper research if the project gives a good result in the purification process, this might be an excellent solution for the above addressed problems.

Abstract:

Increasing automobile emission is becoming a major problem to our environment. The available solutions like catalytic convertors, exhaust gas recirculation are costly and energy intensive. This paper examines the viability of the wet scrubber technology to reduce pollutants in the exhaust gas of the engine. This technology is already being used to reduce pollutants in static applications but not in the automobile sector. It passes the exhaust through a suitable solvent which dissolves some of the pollutants. But the problem in using these scrubbers for automobile emission control is their large size and requirement of external source of energy. In this paper a method to modify the wet scrubber technology to suit the automobile industry has been discussed and its effectiveness has been studied. This paper focuses on proving that the wet scrubber technology can be effectively used for treating automobile exhaust gas. It has been experimentally confirmed that the amount of pollutants in the exhaust could be reduced by 10% by using a wet scrubber.

Abstract:

Automobile exhaust pollution is a serious problem that restricts urban development, and it poses a serious threat to people’s lives and health and even the climate. At present, the treatment of automobile exhaust has attracted people’s attention, and numerous works have been focused on it thereafter. The purpose of the present study is to drive TiO2 nanoparticles application into pavement, and the study present an experimental investigation of performances and automobile exhaust purification of asphalt and its mixture modified by nano-TiO2. In this work, a series of rheometer properties and pavement performances were studied, including penetration, softening point, ductility, DSR and BBR for asphalt binder, conventional pavement performances, and creep test for asphalt mixture. Moreover, the photocatalytic degradation test of automobile exhaust was conducted to assess degradation of TiO2 nanoparticles in the asphalt mixture on automobile exhaust. Results indicate that the TiO2 nanoparticle was beneficial to increase the viscosity and reduce the temperature sensitivity, which would enhance its high-temperature stabilization capability of asphalt. Meanwhile, nano-TiO2 can significantly enhance the rheometer properties of asphalt and its capacity of high-temperature antirutting, and its low-temperature performance could also comply with the specification. Besides, the incorporation of nano-TiO2 in mixtures could effectively enhance the antirutting and anticracking as well as water stabilization. Moreover, the nano-TiO2-modified asphalt mixture possesses a positive impact on photocatalytic degradation of CH and NOx, which could provide a reference for the treatment of automobile exhaust. The photocatalytic degradation effect of asphalt mixtures modified by nano-TiO2 on NOx is significantly better than that of CH.

Abstract:

Currently operation of cars in large cities in winter is the most unfavorable from the point of view of the risk of blocking the exhaust system by condensate accumulated in it. Frequent starts during relatively short period of time, or the cycle of start-up – short run – and subsequent long-term parking at low temperatures are dangerous because the exhaust system does not have time to warm up and remove the accumulated condensate. Daily operation in such modes contributes to rapid accumulation of condensate, and subsequent long-term parking at ambient temperatures below 0˚C are equally dangerous because, depending on the design features of the exhaust system elements, condensation may occur and freeze in the exhaust system, icing can occur inside it or at its exit, causing inability to start the engine. Given that most of the territory of Russia is located in the areas of moderate and cold climate, the relevance of studies, aimed at identifying the patterns of condensate formation and accumulation in the exhaust system, at adjusting on this basis the frequency of condensate removal from the exhaust system, as well as at optimizing the design parameters of the exhaust systems, is quite evident. The objectives of this study were: to identify the features of changes in temperature of the elements of the exhaust system when the automobile engine warms up at low ambient temperature, the effect of various modes of the heater operation on the temperature of the elements of the exhaust system, as well as the features of the temperature change of individual elements of the exhaust system depending on time for various ambient temperatures. To achieve those objectives a series of experiments has been conducted to study the process of starting the «cold» engine, and of its warming up in idle mode. The found dependencies can be used to develop methodology to adjust the recommended periodicity of warming up of the exhaust system, as well as a model of a device that will ensure the absence of condensate in exhaust systems during the operation of cars in large cities during winter period.

Abstract:

This paper analyses the correlation between automobile exhaust, PM2.5, and air pollution to explore the rate of contribution of automobile exhaust to PM2.5 pollution and the effect of government regulation on automobile exhaust gas. The results show that the atmosphere is hazy and that car exhaust is the main cause of PM2.5 pollution. This paper divides the governance strategy into two methods: reducing the number of motor vehicles and reducing the emissions capacity of motor vehicles. It also analyses the effects of congestion control on public car travel and establishes a dynamic game model. To strengthen the influence of supervision on enterprises with regard to purifying devices and restrictions, this study also creates a “prisoner’s dilemma” model. The final results of the study show that restriction measures can effectively relieve road pressure. Additionally, congestion costs can alleviate environmental pressure, but it is difficult to determine the costs, and the difficulty of implementation increases. Increasing enterprises’ installation of purifying devices is not advisable or desirable in the short term. Finally, the paper offers some suggestions for the maintenance of the atmospheric environment and the management of automobile exhaust: (1) improve the national green transport system and environmental protection awareness; (2) advocate public transport as a mode of travel; and (3) reduce the use of buses and popularize new energy vehicles.

Abstract:

With the increase of car ownership, mobile pollution has become an important source of air pollution, which makes it more difficult for China to control air pollution. In order to control mobile pollution from automobile exhaust, China has taken a series of comprehensive measures. The paper studies the emission reduction effect from the perspective of flow pollution and stock pollution. First of all, the paper uses the actual emission data of motor vehicles to study the emission reduction effect by gasoline and diesel vehicles. The results show that: (1) Fuel price, fuel tax (except diesel), and emission and gasoline standards have an emission reduction effect on gasoline vehicle exhaust control, while the restriction has no effect. (2) In gasoline cars, the emission reduction effect in the Middle East is more significant than in the West, and the effect in the West is better than that in the Middle East. (3) As for diesel vehicles, the effect of policy in the West is superior to the East. Further, the east is better than in the middle. Secondly, based on the actual emission data of Chinese motor vehicles, the paper simulates the change value of stock pollution from automobile exhaust under different policies, and concludes that the economic effect of policy depends on the ecological absorption rate and discount rate. When the net discount value NPV is positive, the government should do its best to interfere with the emission of automobile exhaust. When the net discount value NPV is negative, the government doesn’t have to interfere with the emission of automobile exhaust.

Abstract:

In order to gradually reduce automobile exhaust pollution and improve fuel quality, the NOx sensor, which can be monitored in real time in an automobile engine’s electronic control system, has become an indispensable part of the automobile lean burn system. In these types of NOx sensors, Au-doped platinum electrodes have received great attention due to their selectivity towards NO. However, the reaction process of NO gas on the Au-doped platinum electrode in the sensor and the possible regulation mechanism is still unclear. In this paper, the density functional theory (DFT) was used to analyze the effect of Au-doped Pt electrodes on the performance of nitrogen oxide sensors in automobiles. Firstly, the adsorption energies of NO molecules on pure Pt and Au/Pt surfaces were compared. The adsorption and dissociation of NO on Pt substrates doped with Au monomers, dimers, and trimers were investigated. These results showed that Au can effectively weaken the adsorption energy of NO molecules on a Pt surface. It was noted that with the increase in the number of Au atoms on the surface of Pt(111), the adsorption capacity of NO molecules on the alloy surface becomes weaker. When observing the transition state of NO decomposition on three different alloy surfaces, the study showed that the activation energy and reaction heat of NO dissociation increased. It further showed that doping with Au increased the activation energy of NO decomposition, thereby effectively inhibiting the decomposition of NO.

Abstract:

Automobile exhaust emissions are the main source of pollution at present, and Three-Way catalytic converter (TWC), as the main mean of automobile exhaust purification, can effectively control the negative impact posed by automobile exhaust. However, there are still some problems that can be improved in the current TWC, such as catalyst sintering and low temperature catalytic efficiency. As an advanced catalytic field, it has a good effect on CO governance in TWC. This paper mainly studies how single-atom catalysis catalyzes CO in TWC based on related literature researches and analyzes the mechanisms and experimental data from other teams. The preparation method of SAC will also be introduced. It is concluded that SAC has a good effect on CO catalysis in TWC, and it can also improve the existing problems in TWC. Different supports also have different mechanisms for CO oxidation. In the future, if SAC can be applied in TWC, all aspects will be significantly improved.

Abstract:

Vehicle exhaust seriously pollutes urban air and harms human health. Photocatalytic technology can effectively degrade automobile exhaust. This work prepared g-C3N4/CeO2 photocatalytic material by constructing heterojunctions. Four kinds of g-C3N4/CeO2 composite photocatalytic materials with different mass ratios were prepared. An indoor exhaust gas purification test was carried out under natural light and ultraviolet light irradiations. The optimum mass ratio of g-C3N4 material and CeO2 material was determined by evaluating the exhaust gas degradation effective. Moreover, the structure and morphology of the g-C3N4/CeO2 composite were investigated with microscopic characterization experiments (including XRD, TG-DSC, FT-IR, UV-Vis, SEM and XPS). The results obtained were that the optimum mass ratio of g-C3N4 material to CeO2 material was 0.75. The degradation efficiencies under ultraviolet irradiation in 60 min for HC, CO, CO2, NOX were 7.59%, 12.10%, 8.25% and 36.82%, respectively. Under visible light conditions, the degradation efficiency in 60 min for HC, CO, CO2 and NOX were 15.88%, 16.22%, 10.45% and 40.58%, respectively. This work is useful for purifying automobile exhaust in the future.
