Automobiles: What will happen if we press electric start button in running engine condition of a bike..?



Question by Ram: 

What happens if we pressed an electric start button for a vehicle which is already started?
I pressed my bikes electric start button while riding my bike....!! does it harms bike??

Best Answer by Harish Jharia: Chosen by Asker

Electric start system has an electric motor that turns the engine shaft at a rate of RPM (revolution per minute) sufficient for starting the engine of your bike. 

In fact electric start is a substitute to mechanical start feature known as 'Kick'...
If you push the electric start button / key in running engine... it will result in a condition similar to that you push the kick in the same condition...

Practically it will not harm the vehicle... nevertheless, it is not desirable and you should not do it intentionally...

Sky-Rocketing Petrol Prices In India Reaching The All-Time High At Rs 77.54 Per Litre

Serpentine queues at petrol pumps on the eve of petrol price hike 

© Harish Jharia 

Finance and economics are the subjects that I usually do not understand. I always avoided trying to understand how the foreign exchange rates between Indian Rupee and US Dollar are specified. Frequently increasing petrol prices are also similar calculations that I always avoided to learn or even understand. 

Nevertheless, the recent price rise of Rs 7 plus made me motivated to learn some basic idea about the pricing of petrol in India. I learnt it by a simple comparison between the petrol prices in Ashburn, VA, USA and that in Indian cities like Delhi, Kolkata and Chennai. 

To my utter surprise, I found that the price per litre of this essential commodity in the United States continues to be around  $ 0.9854 unit currency of the US; whereas, the price of the same commodity in India is far more than Rs 70 unit currency of India.  The ratio of  0.9854 : 70 does not deserve any comparison.

My study goes as follows…

Ashburn, VA, USA Gas price $ 3.73 per gallon 
@ US price, the rate per litre would be $ 0.9854 
The price of 1 litre of petrol in US would have been Rs 54.197
Rate per Litre: India (Delhi) price in Rs 73.14 – US price in Rs 54.197 = Difference in Rs 18.943

New Delhi, Delhi, India Gas price Rs 73.14 per litre 
@ India price, the rate per gallon would be Rs 276.835
The price of 1 gallon of petrol in US would have been Rs 205.15
Rate per Gallon: India (Delhi) price in Rs 276.835 – US price in Rs 205.15 = Difference in Rs 71.685

Conversion rates: 
1 Gallon = 3.785 Litre
Rs 55 = 1 US Dollar 
-----------------------------------------------------------------------
Reference: VirginiaGasPrices.com… 
URL: http://www.virginiagasprices.com/index.aspx?area=Ashburn
-----------------------------------------------------------------------

The above calculation shows that even if we convert US Dollars @ Rs 55 the difference between the prices of 1 litre of petrol in US and Delhi, India is definitely Rs 19/- approx. This difference in Kolkata and Chennai, India would be Rs 23.343.

But, this is not the real difference; the real difference is rather between US Unit Currency 0.9854 and India Unit currency 77.54 = Unit currency 76.5546. We should rather think practical and accept the fact that the difference in the prices of petrol between US and India is of 76.60 unit currency per litre. 

We should review the basic economic policies followed in respect of petrol prices; because, petrol is the life line, in real sense, of any modern country. If we look at the government taxation for petrol in India, we will find that it is almost 100% of the basic price of Rs 42.57 at which the Indian Government supply petrol to the dealers. Against this basic price the taxation, including the dealer’s profit, comes out to be Rs 34.97. Please see the break-up in the successive lines. 

It is reported that the approximate breakup of the pricing of petrol in Kolkata and Chennai, India is as follows:
  
Basic Price of Petrol - Rs 42.57
42% Government taxes – Rs 33.47
Dealers profit of Rs 1.50 
-------------------------------------------------------------------------------
Total Price of Petrol - Rs  77.54 (Kolkata and Chennai, India)
--------------------------------------------------------------------------------

Conclusion:

It is evidently clear that the sky-rocking prices of petrol in India are basically due to the arbitrary imposition of taxes on this essential commodity. Being one of the most essential commodities, petrol should have been considered for special consideration by the government at the time of imposing taxes. Petrol should not be used as a revenue generating commodity. 

In spite of the above fact the Indian government has decontrolled petrol and left the commodity to the petroleum companies to market it at their convenience. Nevertheless, the government has not reduces the taxes on the same and continued to be a silent spectator watching Rs 42.57 worth of petrol being sold at an unbelievable price of Rs 77.54 per litre. 

I appeal to the Government of India and to all the State Governments in India to reduce taxes on petrol in order to bring it to a price less than Rs 50/- per litre.

Design Development for Automobiles: Develop Corner-Lights on Cars for Safe Night-Driving At Turnings under Poor Visibility


                      
© Harish Jharia

Driving cars in India is a real troublesome job because of the bad condition of roads, crowded traffic, inadequate street lighting and poor traffic sense among drivers and pedestrians. It becomes dangerous and even fatal when we need to drive in pitch dark nights in a congested locality and turn the car at 90 degree angles.

Deficiency in the Present Design:

On turnings at right or left in pitch-dark nights we need to almost stop the car at the turnings because our headlights illuminate the road straight in the front. We are not able to see the road, beyond the turning, where we are about to turn. There are possibilities of some pedestrian walking on the dark road. There might also be a bicycle rider or a rickshaw moving on the dark road. There might be anything beyond our imagination and something against which you may bang your car if you keep driving carelessly.

Design Development Suggestion:

I think we should have some additional corner lights at both the right and left front corners in addition to the present headlights. Corner-lights may have specifications approximately as suggested in the following points, subject to suitability to the overall design of the automobile:
  1. The corner-lights may be installed as parts of the headlights or be installed separately at the outer sides of the headlights or right under them.
  2. The corner-lights may also be installed in place of the fog-lights, replacing them.
  3. The axis of the corner-lights may be kept somewhere between 15 to 30 degrees outwards from that of the respective headlights.
  4. The luminosity of corner-lights should be sufficient to illuminate about 25 feet in the direction of its axis.
  5. The reflector of corner-lights may be designed in order to achieve its requirements
  6. The corner-lights are also required to be at the ‘low beam’ angle
  7. In standing position and during straight driving the corner-lights will remain switched-off.
  8. While turning the vehicle at right or left, the respective corner-light may be operated with the help of the side-indicator lever.
  9. The particular corner-light will be turned-on when the side-indicator lever is turned towards that side.
  10. Eventually, the side-indicator and the respective corner-light will glow together.

Alternate designs already in vogue:

               Xenon Adaptive Headlight

An alternate system called Adaptive headlights is already being used on some specific models of super-luxury cars like BMW and Audi. Nevertheless, their technology is too advanced for Indian cars manufacturers to adapt and exorbitantly expensive for the customers to afford.

What are Acoustic Noise Barriers?

Noise barriers are solid obstructions built between the roads and the residential houses along highways. They do not completely block noises; nevertheless, they reduce overall noise levels. Ideal noise barriers may reduce noise levels by 5 to 10 decibels (dB), reducing the loudness of traffic noise by almost half. For example, a barrier designed for a 10-dB reduction can reduce sound level of a typical tractor trailer equivalent to an automobile like car or SUV.

Acoustic noise barriers are made of different materials viz cement, wood or specific synthetic materials. Their thickness (usually 6-8 in) and height (usually 15 ft) are designed according to the traffic and geo-environmental conditions.

Review Automobiles: Ford Fiesta 1.6 Duratec EXI (Limited Edition*)


          Ford Fiesta 1600cc Petrol (Limited Edition)


© Harish Jharia                                                              

Ford Fiesta 1.6 Duratec EXI (Limited Edition*) is a 4-Door Sedan huge luxury car with all the modern facilities supported with the latest state of the art technology. It is the most dependable car I have ever seen in my life. I am using the limited edition of Ford Fiesta 1600cc for the last more than a year and have faced no problems what-so-ever. 

I would like to mention here that my car met an accident when another car hit at it head-on at the co-drivers door. Yet, the co-driver sitting on his seat at the front, escaped unhurt. The side beams and the inner strong framework on its body withstood the impact and the car became as good as a new-one after repairs in the Ford service center at Noida, Delhi. 

Distance to empty (DTE) display Tachometer: 
It was amazing for me to find digital display of the distance that could be driven with the petrol filled in the fuel tank of the car. When for the first filling I went to the petrol pump (gas filling station) I had a real surprise on watching "Kilometers left for the petrol pump" displayed on the dash board. 

Ford Fiesta 1600cc has a newly designed Power Control Module PCM for improved refinement, lower fuel consumption and reduced emissions, in spite of the huge size of 1600cc engine. 

The more stunning feature on this American Sedan is Generic Electronic Module GEC that is an on-board computer that controls engine diagnostics. Nevertheless, you will have a lot of limitations for getting it repaired. You will have to contact the ford service center for repairs rather than showing it to some roadside motor mechanic or small automobile workshops.  

Key Factors:

The combination of the following four key factors makes Ford Fiestas drive-dynamics the leader in its segment:
  1. Handling- You will find cornering ability, predictability and straight running of the car.
  2. Steering- Simply on holding the steering you will enjoy the feel, response and precision. A small turning radius of 4.9 meters helps in maneuverability in tight traffic conditions specifically found in Indian roads.
  3. Ride quality- Enjoy the quiet interiors with no vibrations, no harshness and body motion of the car (petrol model).
  4. Directional stability and car control during braking- The 4 channel Anti Lock Braking System (ABS) with EBD further complements this element of the Fiesta. this will provide added safety and reliability while applying breaks on muddy ground under heavy rains.

Car Driving Maintenance and Repair: How to Start Car with a Weak Battery?

© Harish Jharia

Driving car is a passion rather than a basic requirement of our daily life. When we board a car, we would always like to be on the driver’s seat, as occupying the drivers seat is a real pleasure in our life. We dream about a life where our first desire would to be an owner of a car. Car gives us comfort, luxury and status in the eyes of the onlookers.

We approach our car press button on the remote occupy the driver’s seat and drive away to our destination. We need not wait for the bus. We do not make ourselves a part of the crowd rushing to occupy a seat in local trains and metros. We feel ourselves the luckiest family having a prize possession that is a Car.

In spite of all the above we sometimes become targets of peculiar gaze of the onlookers when our car breaks down or we become a traffic-stopper and vehicles on our rear blare and honk on us. We sometimes land in a trouble because of minor faults in our car or due to our poor expertise in driving.

Let us discuss a common problem that we face with our cars and the probable ways to address it without taking help of some trained Motor Mechanic:

 Jump-start a car with the help of other car 

If our car battery is older than 18 months then its capacity for recharging and in turn providing adequate power supply to the self-starter to start the car, is considerably reduced. In such cases, the automobile workshops advise us to replace the battery with new ones. Yet, during the intervening periods, we need to know the ways to start the car.

We face similar problem when we keep our car unused for prolonged periods and the battery is discharged on its own.

1.    Push Start: 

There are two ways to start a car with a weak battery. The first one is our age-old system of ‘Push Start’. The user’s guide provided by the car-manufacturers along with the vehicles do not recommend this way of starting the car. Yet, we have to resort to this way if the car stops in a remote place where there is no other way to move vehicle and reach out for a safer place.

First, make adequate arrangements for moving the car manually. Here are the ways to move the car manually for ‘push start’. Place your car on a down gradient and let the car roll down for picking-up adequate speed for moving it in 2nd gear. The other way is to take help of someone to push the car from the rear for achieving a desired speed.

Now, before moving the car you need to occupy driver’s seat and take the following actions in proper sequence:

Move the gear lever to ‘2nd gear’; press the clutch paddle full; press the accelerator a little; insert the ignition key and twist it to ‘switch-on’ position; Now ask someone to push the car as described in the proceeding paragraph. Wait for the car to achieve the desired speed.  Then release the clutch until the engine starts. Your car engine will start running.

Push the clutch again and bring the gear lever to ‘neutral gear’.  Now either you run the engine in idle condition or else drive away to your destination.

2. Jump Start: 

The recommended way to start a car is by ‘jump start’ system. For this you need to have a well-charged battery or else you may use any other battery fitted on a car.  Now you need to have a pair of two-meter long thick electric cables strong enough to withstand 30amp load. There should be crocodile clips properly attached to both the ends of the cables.  Patented ready-made ‘Jump Start’ cables are also available in the market and it is advisable to have one pair of cables in our car for crisis management.


Foreign Resized

The ‘Jump Start’ procedure is simple. Bring the other car near to your car; connect the red cable to the Positive Ports (marked +) of batteries of both the cars; connect the black cable to Negative Ports (marked -) of both the batteries. By doing this you have connected the well-charged battery of the other car to your car. In other words, you are now using the battery of the other car for your own car.

Now occupy the driver’s seat; bring the gear lever to ‘neutral gear’; push clutch paddle full; insert ignition key in its slot and start your car as usual. For keeping the engine running apply hand break; let the car be in ‘neutral gear’; let the ignition key remain in its slot; open the window glass of driver’s door and come out of your car leaving the engine in ‘idle running’.

Remove the cables and keep them in your trunk. Shift the other car to its original place. Now you should drive away for recharging your car battery. Go for a long drive at least for 5 – 10 km possibly at lower gears and essentially without putting-on your AC.

In this way your battery will be recharged for your normal use.  In some types of batteries, you need to check the acid-level in the battery. If the level has gone down you may pour some distilled water by opening the caps with the help of a coin.

In general, Battery-life is specified between 18 – 24 months if your battery has crossed its 18-month life, then you have to be vigilant about your battery, as it would not recharge well and supply inadequate power output required by the self-starter to start your car-engine. Eventually, you should change the battery at right time. There are good exchange-offers in the market, so that you may exchange your old battery with a new one at a lower rate even before it is completely drained-out.
