(APP): National University of Science and technology ( NUST) Saturday introduced first hybrid scooter and motorcycle which will be fuel efficient and low in pollution. Besides this, the students of NUST have also introduced first hybrid car in Pakistan which does not produce much pollution and consumes minimal fuel; and its different propulsion systems have either common parts or systems. This technology is called the hybrid car technology where the cars have a rechargeable energy storage system (RESS) found in the vehicle, along with some fuel propulsion source. Spokesman NUST, Irshad Rao said “No matter, the prices of gasoline and fuel keep on increasing, hybrid technology will enable everyone to afford car”.
Moreover when such cars cruise, or move on a small thrust, the combustion engine generates energy with the running of a second electric motor.
This is done to either recharge the battery or to provide energy to the motor for driving the car. This is unlike the conventional electrical cars where they charge their battery through external sources like the grid.
Today, most of the hybrid cars run on either gasoline or diesel as their main energy source while there are some cases where other fuels like ethanol or plant based oils are used too.
There are also some cars that use hydrogen fuel. Sometimes, hybrid cars are also referred to the cars that are flexible-fuel vehicles where they run on a combination of different fuels like gasoline and ethanol alcohol fuel.
With this, a lot of gas fuel is saved which is of course, beneficial to the car buyer.
Spokesman NUST said “ With the passage of time, hybrid cars will become popular and the manufacturers will working on more means to make the car more feasible to the prospective car buyer”.
With hybrid car technology, the motion of the car is designed in such a way that the engines in these cars have a smaller size that is used when drifting and driving leisurely.
It is usually the battery source that provides the additional power like going uphill or accelerating whenever needed. To couple things, when the hybrid car is stopped, the hybrid fuel engine gets switched off to run off the electric motor.
Hybrid cars are built lighter and are designed more aerodynamically for better speed.
And its tyres are usually stiffer and have a higher inflation so that the drag of the car is reduced.
Spokesman NUST said,with hybrid car technology, a car becomes more efficient, adding though the rates of these cars may initially be a bit high.
He further said that a workhsop is established at NUST, which will soon start production of hybrid cars,motorcycles and scooters on larger scale.
