The purpose of this study was to substantially analyze the relation between the success factors of quality management and performance. For this purpose, the success factors of quality management - CEO's leadership, customer-centeredness, process management, training, full participation of employees, and relationship with vendors - were identified as independent variables and performance was identified as dependent variable to substantially analyze the automotive parts industry. In result, the findings can be summarized into the following: First, for the relation between the success factors of quality management and financial performance, CEO's leadership, customer-centeredness, training, and full participation of employees were statistically significant, but process management and relationship with vendors were not statistically significant. Second, for the relation between the success factors of quality management and non-financial performance, CEO's leadership, customer-centeredness, full participation of employees, and relationship with vendors were statistically significant, but process management and training were not statistically significant. Third, it was also found that, among the success factors of quality management, CEO's leadership, customer-centeredness, full participation of employee should be considered more than any other variables to achieve performance. Based on the above findings, it was concluded that 'CEO's leadership' and 'customer-centeredness' had an influence on both financial and non-financial performances and were relatively more influential than other individual factors.

Corporate governance and innovation have been a hot topic in recent boardroom talks, whether in the trade or manufacturing industries. Governance innovations are highly significant for the survival of the motor vehicle industry like Honda, Nissan, New General Motors, and Toyota. The study chooses the motor vehicle industry which crosses the age of a century and sufficient corroborative support exists with the perspective of distinctive objectives. Using the population of all the automobile companies listed on the Pakistan stock exchange (PSX), we distill automobile companies to evaluate the firm performance using the panel data regression approach. The results show that there is a significant relationship between gender diversity, audit committees, and firm performance. Further, board size also has a positive impact on firm performance. We identify that the governance mechanism of firms found in default of the frequency of audit committee meetings. By considering results, only limited knowledge of finance directors and also very few numbers of female directors are on the board. Empirical findings of this work might be useful for policymakers in attempting to draft a corporate governance framework better able to monitor the financial performance of firms through female directors and also serve as a catalyst for the regulators of electric vehicles.

The automotive industry as the major industry of the nation has affected both society and economy since the automobile was invented, and the main technique that help to performance improvement of the automobile has been developed. But, the painting technique lags behind the main technique of the automobile because that was neglected. Specially, we can say that in case of the painting technique of the automobile of our nation is so weak situation. After we changed the injecting pressure, the composition ratio (paint, hardener, thinner) and the injecting flow rate from spray-gun by PDPA, we studied the character of the injecting velocity and droplet size, and found the fittest condition. So, we got the following result to help mending paint technique of automobile surface. We could know the following fact from the experiment result. When it does mending paint of automobile, there is most suitable that to inject the paint as injecting pressure 200∼300 kPa and to inject the ratio of paint 10 : 1 : 1 when the fluid adjective knob valve spay-gun is open full.

ISO9000 set of standards has been widely applied in Iranian Automotive manufacturing industry. Regarding the effects of TQM and ISO9000 set of standards various studies have been conducted and different quantitative conclusions have been made. Due to lack of quantitative information, in many of the cases, using qualitative information becomes the best option. The qualitative nature of data in such cases, requires qualitative analysis methods that might lead to some challenging computational issues. This paper examines the impact of ISO9000: 2000 certification and its perceived benefits for an automotive manufacturing company. Using an empirical approach, the paper seeks to ascertain if certification has indeed improved the performance of the company. Our null hypothesis rotates around the effect of ISO9000: 2000 on the 4W's of an enterprise. To carry out the research, first we developed a couple of questionnaires including all criteria of ISO9000 and 4W's. Second, the questionnaires were discussed with two researchers knowledgeable in the field, and then submitted to the quality practitioners and executives of Iran Khodro Enterprise-a leading company in Iranian automotive manufacturing industry. Finally the null hypothesis was tested and the technology improvement dimensions were ranked through nonparametric tests. The results illustrated a reasonable cause and effect relationship, suggesting that ISO9000: 2000 has positive effect on the 4W's of company result. In this work we investigate the effect as technology improvement viz., the improvement of techno-ware, human-ware, info-ware, and organ-ware.

For the environment protection, carbon dioxide as a natural refrigerant has been studied to use in an automotive air conditioning system. Hence, a numerical model has been developed to describe the evaporation phenomena of carbon dioxide flowing through very small diameter tubes. The two dimensional low-Reynolds $k-{\varepsilon}$ model was used to predict the flow phenomena of carbon dioxide in the two phase during its evaporation. Furthermore, the results obtained from the model were compared with the experiments for the validation. The heat transfer coefficient is lower, as the tube inner diameter becomes smaller. However, the amount of heat absorbed by a unit mass of carbon dioxide is greater due to more surface area. Therefore, the small diameter tube has advantage in terms of compact design of evaporator. When the inlet condition of pressure and temperature is low, the heat transfer coefficient is slightly high at the same size of tube because of the thermal properties of carbon dioxide.

As DDI or GDI engine discharges very low heat due to its high thermal efficiency, the heat source is not enough for heating the passenger compartment in cold climate condition. To remedy the heating problem, the conventional HFC-134a automotive air-conditioning system has been attempted to run as a heat pump mode. Futhermore, an auxiliary electric heater of new type was equipped to the heat pump air-conditioning loop as a new approach. Hence, a proto-type heat pump air conditioner has been made and tested to investigate the feasibility of the HFC-134a automobile air-conditioning system that could be worked as a heat pump. The experiment results showed that the sufficient heating capacity could be obtained by adding a heat pump with an new electric type auxiliary heater into the conventional heat core in low temperature condition.
