Tata Motors displayed Tata Pixel, new city car concept for Europe at the 81st Geneva Motor Show. Based on the Tata Nano, the Tata Pixel -Tata’s four seater small car concept is just over three metres in length.

Speaking on the occasion, Mr. Carl-Peter Forster, Managing Director and Group CEO of Tata Motors, said, “Tata Motors holds true to its belief that there is an opportunity in Europe for a city car, which is optimal in space, manoeuvrability and environment-friendliness. The Tata Pixel is a reflection of Tata Motors’ idea of what such a car should be.”

Tata Pixel is powered by A 1.2 litre three-cylinder turbocharged diesel engine which gives lively performance. The engine is a low-friction design, featuring variable coolant and oil pump and rapid warm-up technologies.

Tata Pixel returns European combined cycle (NEDC) fuel economy of 3.4 l/100km and CO2 emissions of just 89g/km.

Tata Motors is also displaying the Tata Indica Vista Electric Vehicle at the Motor Show’s Green Pavillion. The Tata Indica Vista EV will be made available to fleet customers this summer in the UK. The four-seater family car has a predicted range of up to 160 km.

The company’s displays also include the Tata Aria, the first Indian four-wheel drive crossover, which was launched in India recently to rave reviews, the Tata Indigo Manza, among India’s best selling sedans scheduled for launch this year in select countries, and the Tata Indica Vista, a top selling hatch already launched in select geographies. In Europe, the Indica Vista has already been introduced in Poland and Italy, and is planned for launch in Spain. The Tata Aria too will be launched, further enhancing the company’s portfolio in these markets.

Safest Vehicle to Drive on Snowy Roads

Posted by bates70 on November 22, 2010

Safety drive on slippery roads in snow, a four wheel driven car is the most suitable as all the wheels give it power and grip on the road. If you are planning to buy a new car for you, Audi, Mercedes, Volvo, Subaru should be the top choices for driving in snow.
Your wallet may not permit you to go for these expensive cars, you have Ford 500 sedan as an alternative. Ford 500 sedan has both options of either a two wheel or four wheel drives. Freestyle is another recommended car from Ford. It looks like a blend of a station wagon and a minivan.
You may not admire a Ford; then choose from over 50 models of cars having four wheel drives, which include, Acura RL, Dodge Magnum, Cadillac STS, or an Acura RL. It is most important to maintain the car’s radial ply tires in top condition during winter. Regardless of power of an engine, the car will not grip the road in snow if the tires are bad. A regular check up of tires is essential after each drive. The tread on tire should be minimum 1/16 inch for safe driving. This can be approximately checked by inserting a penny in the groove. You should ensure the correct tire pressure which should be checked sporadically. The tires should be interchanged in rotation.
A next best category of cars to drive in snow is with front wheel drive. This is the most common power drive system on cars of different makes. Generally, preferred makes are Dodge, Plymouth Ford, Pontiac, Chevy and so on.
If you want to comprehend the reason for a front wheel driven car being better than that driven with rear wheels, remember: in a front wheel drive the car is pulled. Most the weight of the car is distributed over front wheels. Pulling of the car requires less power, and it moves straight forward, particularly when there is snow or ice is frozen on the road. When the front wheel pulls the car, it can be controlled easily. If the car skids, driver can immediately control it by letting off the accelerator and by steering to escape slip or a twist.

Vehicle is best in snow

Posted by bates70 on November 20, 2010

It is claimed that a four-wheel drive vehicle is best in snow, but I don’t agree. I have on more than one occasion heard owners of SUV’s complaining that they had been driving their vehicle in four-wheel drive and they still crashed in the snow.

What people don’t understand is that driving in four-wheel drive doesn’t mean you should be driving without the obvious caution. Ice and snow will still affect an SUV, it’s just that with four wheel drive, you can get yourself out of a snow drift, or that ditch you’ve just slid into.

You should treat driving in snow with caution, and be aware what is happening on the road. Don’t drive too fast, as you will be unable to control the car if your tyres lose grip. Slow down for any corners, and keep a good distance from the car in front. You might be managing driving in the snow well, but is the person in front coping.

The last heavy snow we had in Scotland, I was driving a front wheel drive estate car. I drove the twelve miles to work one Sunday, and had no control problems at all, because I drove to the road conditions. My problems started once I reached town, when I had the extra hazard of the other drivers. Most of whom either drove too cautiously, or with dangerous over-confidence because their cars were four-wheel drive.

For a driver to manage to safely drive their car through snow, you must make a few preparations. Make sure your tyres are not worn, as a worn tread reduces a tyre’s grip with the road quite dramatically. Take a blanket, and a spade with you; even the best all-terrain vehicle can get stuck. Most importantly of all, take your time, and don’t try to push the speed up when it’s obvious the conditions are not good enough. I know it’s a corny line, but it’s best to take your time and arrive safely, than not at all.

Brake Light Flasher

Posted by bates70 on October 30, 2010

I saw the F1 race and it was raining, I was very interested in the rear brake lights of the cars are race. Cool out!. when the brake lights with F1 style can be applied in my car. The things that really gets other driver attention when i stepped on the brakes. But government regulations prohibit the obtaining flashing brake lights because they endanger other drivers.
The solution is a circuit that will flash the brake lights for a short time when I press and hold brake. After several flashes, the light would stay on continuously, until I released the brakes. The short burst of flashes certainly gets the other drivers attention. Short duration flashes solve the problem of annoying people behind you. I get an electronic scheme on radio shack. With this electronic scheme of government regulatory issues resolved and the purpose of getting attention from other drivers behind you still achieved.

Automotive Brake Light Flasher

Parts List:
IC1 = CD4093UBE, CMOS (4093B)
Q1 = 2N2222
Q2 = TIP117

R1,R6 = 50K trimpot
R2,R5,R7,R9 = 10K
R3 = 100K
R4 = 47K
R8 = 2K7

C1 = 33uF, 25V
C2 = 3.3uF, 25V

PCB flashing brake lights

Circuit Description :
The schematic shows the circuit for the brake light control. It consists of four sections that are un-powered when the brakes are off. When the brakes
are applied, +12VDC (13.8V) is connected to the circuit (point A). The circuit then controls the voltage to the brake light. When the brakes are
released, the +12VDC is removed, and the circuit and brake light are no longer powered.
The first section provides a pulse delay to allow the brake light to pulse for only a short period of time. R1, R2, R3, C1, and IC1a form a
half-monostable inverter. When the brakes are applied, C1 is charged through R1 and R2. When the voltage across R3 reaches the trigger level of C1
the output at pin 3 goes from +12 volts to zero (point B). Trimpot R1 allows the pulse delay time to be adjusted.
Resistor R3 provides a discharge path for capacitor C1 after the power to the circuit is removed (via the brake switch wire). What this means is that
there is no delay for the brake light to come on in between brakes, the flasher works as it should all the time. You can press the brake pedal as fast as
you can and as often as you can, the flasher will work fine every time
The second section provides the pulse rate for the brake light. R4, R5, R6, C2, IC1c, and IC1d, form a free-running astable oscillator. When the brakes
are applied, the circuit is powered and starts oscillation. The pulse rate is determined by the time constant of resistors R5 + R6 and capacitor C2.
Trimmer R6 allows the pulse rate to be adjusted to your personal liking. The pulse rate output is taken from pin 11 of IC1d (point C).
The third section combines the pulse rate signal and the pulse delay signal. IC1b ‘NANDS’ the two signals to produce a series of pulses followed by a
constant high level (point D). This will form the On-Off sequence of the brake light.
The forth section is the driver that controls the output to the brake light bulb. Resistors R7, R8, R9, and transistor Q1 form an inverting amplifier. This
drives the pull-up power transistor, Q2. The brake light will light as Q2’s collector is pulled to +12VDC (point E). The return path to ground is the
chassis or frame. The negative of the battery is connected here also.

Installation :
Installation all depends on your bike’s wiring system but most of them are all the same. Look for the wire coming from your handbrake and footbrake,
mostly combined into a single wire underneath your seat. Cut this wire and mount the flasher unit in between these two wires. One end that goes to
your brake switches is the +12V and goes to point ‘A’. The other end connects to point ‘E’. One wire more to connect and that’s the negative or ground
wire, that one connects simply to your bike’s chassis. In short, cut your brakelight wire and connect this circuit in between.

This design works much better and more reliable then the 555 timer design of the same, elsewhere listed on the circuits page. The 4093 design does
away with the delay. There is no delay for the brake light to come on between quick brake pedal presses and the circuit overall works fantastic and
very reliable.
For the TIP117 (Q2) I used a replacement type made by NTE Electronics, the NTE262. Works great. But a TIP125 or TIP127 will also work.
For the capacitors I used Tantalum types because I had them in stock, but they are not as reliable as standard electrolytic caps.

Indonesia Hybrid & Electric Cars

Hybrid Cars and Electric Cars Made by LIPI Bandung Ready to Mass Production

Eco Products Fair 2010 Internatisional Exhibition in Jakarta Convention Centre (JCC), Senayan which ended on Sunday yesterday (03/07/2010) share followed by LIPI (Indonesian Institute of Sciences). On occasion this time LIPI had two electric cars engineered by son of the nation under the Electric Power Research Center And Mekatronik.

Two of these cars is the Toyota Kijang Super, produced the 90’s as “the 1st Electric Car Conversion”, and a small hatchback “Elecric the 1st Hybrid Vehicle”. “Both engineered LIPI researchers. Kijang is a plug-in electric cars and the little car is hybrid, ” commentary by Indonesian Institute of Sciences Public Relation.
Both use the electric engine as a driving force. An electric motor type 3-Phase Motor Inducton become the main energy producers. What distinguishes, as a source of Toyota Kijang Super energy derived from electricity 220V. It can plug in directly into electricity at home.
Electricity 220V then stored in the battery pack-Deep Cycle SLA volt/220Ah and 72 Ampere 72V/25A charger. If the battery is fully charged condition could use the road 75 kilometers, continued the man from Bandung. Toyota Kijang has an energy 52 dk and 156 Nm of torque is calculated by the rear wheel dynamometer.
Different with a black mini cars. The car actually was built from scratch has an electric engine with a hybrid concept. With electric motor and gasoline engine there is. “But the car still running with 100 percent electric. 160cc Generator is used only to fill the batteries.
We’ve patented a technology that we make in this car. And this car exhibited here is to find investors it is our goal. Who knew there was going to use and produce it.

LIPI claims to have spent Rp. 200 million for research hybridnya car and Rp 150 million for electric cars. And after mass-produced price can be reduced. Maybe Rp. 50 millions, or even cheaper when its production capacity a lot.
