CNG ENGINES

CNG ENGINES

ABSTRACT

             There is no mistaking the fact that alternative fuel sources such as CNG, LPG, hydrogen etc. could be principal fuels powering vehicles of our future. But due to number of safety aspects that were ignored.
              CNG fuel is stored in steel pressure cylinder with a carbon fibre wrap. To use CNG as a fuel, different CNG engines are used. A country can have cleaner environment with comprehensive use of CNG because they emit less nitrogen oxides or hydrocarbons, while new job opportunities and economy are other benefits of using CNG.
              CNG is abundantly available. It is not corrosive or toxic, also it is biologically inert and hence does not create any problem if exposed to lungs or skin. It is lighter than air so it rises up and dissipates into air.     
               We may never see a large percentage of CNG vehicles on the road but it is
one  alternatives to help reduce vehicle emissions.
                Thus CNG use can help in improving quality of life.

ROBONUT

ROBONUT

Abstract

The Robonaut project at the NASA Johnson Space Center is building a humanoid robot for use in space. This robot has a control architecture designed to support teleoperation and development of advanced intelligent control to automate complex tasks. This architecture is influenced by the architecture of human brains that embeds sequencing, safety, and control at a low level. The agent based methodology that allows for a peer to peer interaction between independent subelements is also used in this system. This architecture specifies elements called subautonomies that group together sequencing, safety, and control functions while allowing the elements to be networked similar to agents. This architecture provides a robust and safe environment for advanced humanoid intelligence research by providing low level functionality with system safety implicit in the design. The architecture has been implemented on the Robonaut using experience gained from another humanlike NASA robot project, the Dexterous Anthropomorphic Robotic Testbed. The Robonaut shows the capability of supporting complex orbital, planetary, and medical tasks.

V-TEC THE BOOSTING POWER

V-TEC THE BOOSTING POWER

Abstract

This is the Hondas revolutionary V-Tec system that includes variable valve lifting and in timing in order to optimize an engines performance at different speeds and also as per load condition .Now the Honda is promoting the evolution of its engine technology is to persue higher output through increased engine rpm. Already it has been evident in fomula-1 racing car. That technology but in improved form has been used by the Honda called as V-Tec.Various technical satisfaction are reflected in higher output realized through the acceptation of 3 & 4 valve engine.
