The emergence of recent trends takes place in automotive industry on regular basis. A research has been conducted which primarily focus on advanced energy storage systems and electric propulsion, alternative and engine fuels, vehicular communication systems, intelligent transportation, vehicle chassis systems, autonomous vehicles, and vehicle safety.
Most of the automotive industries or companies are focusing on the improvement of engine efficiency and fuel economy. It includes down-speeding, down-sizing, boosting and direct fuel injection. It also made their focus on transmission improvement, accessory load reduction through management of energy of different other vehicle components, hybridization, new battery chemistry, improvement in battery management systems and power electronics.
Some of the recent trends include:
This technology has been designed so that it can meet life, performance and different warranty goals for batteries and their management and monitoring systems. The companies understand various operational limits that is affecting the life through extensive modeling and testing with the development of sophisticated algorithms so that it can track and predict various parameters.
For the expansion of battery operating range, continuous experiments are performed that includes the designing and testing of new batteries chemistries and subsystems.
Turbocharging and downsizing
For downsizing an internal combustion engine, the two main befits includes mechanical and thermodynamic. The operations of the engine will move towards higher loads where the efficiency of engine becomes higher. It has been found that downsized engines are much lighter than conventional engines. It results in the reduction of vehicle mass and improvement of vehicle fuel consumption.
Advanced combustion modes
For increasing the efficiency of internal combustion engines, advanced combustion modes are developed on regular basis. One of these modes are known as HCCI, that is a mixture of homogenized air, combustion products and fuel from previous cycle that is auto-ignited by compression. It aims ta the combination of gasoline combustion process and modern diesel which states low emissions and high efficiency.
Other research in trends has been conducted which recover the energy through coolant and exhaust gas systems. It is also using innovative waste heat that helps in the recovery of devices. These type of systems helps in the conversion of thermal energy into electrical or mechanical, which further increases overall efficiency of the vehicle.
