Augmentation technologies in Automobiles

Due to excess use of non-renewable resource which are reducing day by day have presented a requirement to provide excellent fuel efficiency and superb performance automobile. There are few technologies which are used by the automobile manufacturers. We all are very aware about their names but let's see the technologies behind them.

I-VTEC (intelligent variable valve timing and lift electronic control)



I-VTEC is the latest modern technology in VTEC development, which combines the features of VTEC and VTC (variable timing control). Due to this combination fuel economy, ample torque, and clean emissions can be obtained. A VTEC controls the intake valve timing and lift , where as the VTC controls the valve overlap timing. In I-VTEC, I stands for intelligent where it can control both, camshaft duration and valve lift, not only change the valve timing for the exhaust and induction strokes.
Currently Honda has adopted I-VTEC in its large capacity four cylinder petrol engines, increasing the fuel efficiency of the vehicle, clear emissions, reducing weight, higher output, increased torque and improving driving comfort with lots of other benefits. This technology was introduced by Honda in 2002 Honda CR-V.

iSmart

 Hero splendor has showcased iSmart model which features i3S (intelligent start stop system). Increasing the fuel efficiency of the vehicle.
In this system if the engine is idling for more then 30 seconds then the engine will switch off the ignition. Including when the engine is in neutral condition put on halt for more then 5 seconds then it shuts off and come back to life while applying the clutch.hence a huge amout of fuel is saved in increases its fuel efficiency. This system is beneficial in the traffic conditions also tagged by the compny as “ fill it, shut it, forget it.”

DTSI (Digital Twin Spark Ignition System)
As we know that an ideal combustion is not possible in any engine. However we can improve its performance by making the combustion of fuel as fast as possible. This is done by using two spark plugs located at opposite ends of combustion chamber. This two spark plus spark alternatively, increasing the area covered by the flame and burning the fuel instantaneously. This is beneficial for our fuel efficiency. It is a digital system static spark advance and moving parts which can wear. The simulation is controlled by digital electronic control box which handles valce timing and fuel injectiom.
It provides many advantages as fuel efficiency, proper combustion, less vibration and noise,more power, long life, no over heating, increase the thermal efficiency of engine, better starting in all weather conditions, instantaneous burning of fuels. In india this technology is adopted by Bajaj, currently used in  platina, xcd125, 135, discover 150,pulsar135, 150, 180, 200 etc.

Stay tuned for more such interesting stuffs!!

Faster than the Fastest production car of the world

Image
One thing about which almost every sports car freak is crazy is their mind-blowing speed. It doesn't matter if you could ever achieve that speed on road or not but you'd always desire to boast those numbers among your friends and groups. So fellas, what do you think? Which car should be the fastest car?  Well, you might be thinking about the  Bugatti Veyron Super-sport or the newly unveiled Chiron. But actually, it's not the case. T hey hold the record of the fastest production car according to the Guinness Book of World Records officially but the “ Hennessey Venom GT ” by Hennessey Performance Engineering is unofficially the fastest car at a whopping speed of “270.49 MPH”. Yeah you read it right. It's 435.11 km/h. To make a claim for Guinness Record for fastest production car the company has to at least make 30 cars, while the company has decided to make only 29 cars which is a bit funny. And this company does not make the whole car, they just tune the engine and...

Muscle Cars - The raw and untamed beasts

Image
Almost every youth on the planet loves speed, obviously after the “Fast & Furious” and “Need for Speed” movies. But when it comes to defining the Muscle car, the things get a bit complicated. As the name suggests, the built up of this automobile is taken care, not only from within but also from the exterior parts. As per American norms, a muscle car can be defined as a two door; rear wheel drive, mid-size cars with powerful engines. These cars are considered as high-performance vehicles compared to other normal ones. Comparison between a muscle car and a sports car:- ·         Engine :- A muscle car uses a V8 engine while an engine of a sports car may be small but is quick. Thus the engine of muscle car is powerful while the same of sports car is quick ·         Bodies :- The muscle cars are made up with lots of curves while a sports car is built with an aim of reducing the force that is appl...

Hydrogen Fuel - The Fuel of the Future

Image
                                                                               As we often hear in our day to day lives, the availability of fuels is decreasing day by day and the biggest concern in automobile is pollution due to these fuels, so the new idea and search comes for zero pollution as well as the better availability, renewability and efficiency too. Although, many researches are going on for the alternate fuels but one of the most promising fuel source is Hydrogen which can produce an abundant amount of energy and that too with zero emissions. Hydrogen may seem to be very abundant but pure hydrogen is not naturally available on earth in large quantity. So, electrolysis and steam-methane reforming processes are methods to produce hydrogen. In electrolysis, the electri...
