India is densely populated and has high solar insolation, which varies from 4 to 7 kWh/ (m2.day) with about 1500-2000 sunshine hours per year. Transportation sector is a major source for global carbon emissions and also contributes to air quality concerns, particularly in urban areas. In view of above, development of a passenger solar electric hybrid vehicle program has been initiated. The team is currently working towards the development of a solar passenger electric hybrid vehicle with an aim to reduce environmental pollutants by incorporating innovative energy efficient green technologies. The broad objectives of this project will be to Reduce dependency on fossil fuels, to preserve environment through sustainable mobility solutions, and To penetrate Solar Hybrid Vehicle technology in the Indian Market at an affordable cost.

With more stringent emission norm coming in future, add more pressure on IC engine to improve fuel efficiency for survival in next few decades. In gasoline SI (spark ignition) engine, valve events have major influence on fuel economy, performance and exhaust emissions. Optimization of valve event demands for extensive simulation and testing to achieve balance between conflicting requirement of low end torque, maximum power output, part load fuel consumption and emission performance. Balance between these requirements will become more critical when designing low cost valve train without VVT (Variable valve timing) to reduce overall cost of engine. Higher CR (Compression ratio) is an important low cost measure to achieve higher thermal efficiency but creates issue of knocking thereby limiting low speed high load performance. The effective CR reduction by means of late intake valve closing (LIVC) is one way to achieve higher expansion ratio while keeping high geometric CR.
