Government launches BS-IV grade fuels

Government has formally launched Bharat Stage-IV (BS-IV) grade transportation fuel across the country to keep carbon emission in check. The launch came days after the Supreme Court banned sale and registration of BS-III vehicles from 1 April, 2017. It sets target of ushering in BS-VI fuel by April 2020 by skipping BS-V fuel. All state-run oil marketing companies will provide BS-IV-compliant fuel at their 53,500 retail fuel stations across the country. BS-IV fuels BS-IV fuels contain far less sulphur than BS-III fuel. Sulphur in fuel makes it dirtier and lowers the efficiency of catalytic converters, which control emissions.The BS-IV complaint vehicles release less pollutants Carbon Mono-oxide (CO), Hydrocarbon (HC), Oxides of Nitrogen (NOx), Sulphur (SOx) and particulate matter (PM) compared to BS III complaint vehicles. About Bharat stage emission standards BS emission standards are emission standards instituted by the Union Government to regulate output of air pollutants from i...

GE6757 Total Quality Management-Question and answer

DEPARTMENT OF MECHANICAL ENGINEERING QUESTION BANK NAME OF THE SUBJECT: TOTAL QUALITY MANAGEMENT YEAR / SEM: IV / VII UNIT- I INTRODUCTION PART – A (2 MARKS) 1. Define Total Quality? TQM is an enhancement to the traditional Way of doing business. It is the art of managing the whole to achieve excellence. It is defined both a philosophy and a set of guiding principles that represent the foundation of a continuously improving Organization. It is the application of quantitative methods and human resources to improve all the processes within an organization and exceed customer needs now and in the future. It integrates fundamental management techniques, existing improvement efforts, and technical tools under a disciplined approach. 2. Define Quality? Quality = Performance x Expectations 3. What are the Dimensions of Quality? •Features •Conformance •Reliability •Durability •Service •Response •Aesthetics •Reputation 4. Give the Basic ...
