Visibility through windscreen along with front lighting system is one of the most important elements of road safety. Windscreen also provides the good visibility to driver to drive safely during night time. As per the rule windscreen visual light transmission should be minimum 70%. Windshields are made-up of tinted glass which produces light transmission varying from 70% to 95%. Windscreen installation is various from vehicle to vehicle, the visual light transmittance at different installation angle and its effect to the visibility are not fully understood. Vehicle headlamps and front fog lamps are evaluated for the illumination without consideration of driver's visibility with the combination of wind screen and its installation angle. This paper describes the effect of different ranges of tinted wind shield glass on driver's visibility at various installation angle of windshield along with the headlamp illumination.

Natural Gas is one of the abundant fuel available on the earth and considered as a one of the cleanest fossil fuels. Most of the studies are conducted on CNG with different blends of hydrogen to improve the efficiency of engine and reduce the emission. However, components safety and its compatibility to these fuels were not studied in depth. Project was taken to understand material compatibility of CNG kit components and framing the National standards which can also be used for providing the inputs to international standards like ISO, ECE etc. Various components have been selected a sample base from CNG fuel kit for this study such as Refilling Valve, High Pressure Regulator and Gas Solenoid Valve, Rigid Pipe, low pressure flexible hose, etc. from renowned manufactures in the country and around the globe.

Fatigue design has to account for the scatter of component geometry, material behavior and loading. Scatter of the first two variables is mainly due to manufacturing and material sourcing. Loading on the other hand depends decisively on operating conditions and customer usage. Loading is certainly most difficult to determine. Tests on proving ground or even long-term real time measurements are used to obtain actual load time histories. Because of the costs of measurements and safety measure, real-time measurements are used exceptionally to gain changes in the usage profile. In this paper, an attempt has been made to find the difference in the extrapolated data to the actual data. A comparison has been made between the actual road distance of 2000 km to the extrapolated data of 100 km, 500 km and 1000 km to 2000 km. The front Axle channel is taken for the study.
