The first documented use of a spark plug in an internal combustion engine was attributed to the Belgian Engineer Jean Joseph Étienne Lenoir in 1859. Lenoir is known for developing the first internal combustion engine, which burned a mixture of coal gas and air. The air-fuel mixture it aspirated was ignited by a "jumping spark" ignition system, which he patented in 1860. Lenoir’s ignition system created sparks by using high voltage electricity to jump an air gap. This was accomplished by sending mechanically generated low voltage pulses through a type of electrical transformer known as a Ruhmkorff coil. The coil would transform the low voltage pulses into lower current, high voltage pulses, suitable for spark generation.  Reliably igniting over 20 million combustion cycles while surviving exposure to the extreme temperatures and pressures of ignited fuel would prove to be a formidable challenge. All spark plugs are fundamentally composed of two elec

If we use cell phone at petrol station its radiation can make any spark in some machine of the patrol station.And a little spark can make a big explosion.So,Better stay away from it because It is better to safe than sorry

    This is brand new car of modern age which TATA motors had introduced in Geneva Motor Show. Combining a lithium ion phosphate battery and an on-board petrol engine generator for recharging on the move, the Tata Megapixel offers a range of up to 900 km (with a single tank of fuel), path-breaking CO2 emission of just 22 gm / km and fuel economy of 100 km / liter (under battery only power).

The project aims to herald a new age of relaxed driving A convoy of self-driven cars has completed a 200km (125-mile) journey on a Spanish motorway, in the first public test of such vehicles. The cars were wirelessly linked to each other and "mimicked" a lead vehicle, driven by a professional driver. The so-called road train has been developed by Volvo. The firm is confident that they will be widely available in future. The project aims to herald a new age of relaxed driving. According to Volvo, drivers "can now work on their laptops, read a book or sit back and enjoy a relaxed lunch" while driving. The road train test was carried out as part of a European Commission research project known as Sartre - Safe Road Trains for the Environment. The convoy comprised three cars and one lorry. Special features "Driving among other road-users is a great milestone in our project. It was truly thril

Audi, the company that brought you hybrid-diesel racecars, has an intriguing two-wheel concept vehicle: an ultra-light carbon fiber electric bicycle that has WiFi built in, can hit 50 mph, and even has a Segway-like mode that lets it run on just its back wheel (apparently clever computers and gyroscopes will keep you balanced). Audi unveiled it at the 2012 Wörthersee Tour in Austria — and the e-bike itself is also called Wörthersee (which happens to be a beautiful lake in Austria). The carbon fiber frame weighs just 3.53 pounds (1.6kg) — but with a 2.3kW electric motor and lithium ion battery the bike’s total weight is 24lbs (11kg). It’s pegged as a high-performance bike for trick cycling, including the ability to ride on its back wheel alone in two of the five modes: Pure, Pedelec, eGrip, Power Wheelie, and Balanced Wheelie. Audi says the e-bike travels up to 31 mph on the electric motor, and up to 51 mph when the rider pedals as well. The battery can be charged i

If your car is going to hit bumps in the road, it might as well get a little power. At SUNY Stony Brook, mechanical engineering professor Lei Zuo invented a shock absorber that converts the kinetic energy from vibrations into electricity. Electric and hybrid cars already convert the kinetic energy from braking in to electricity that's used to recharge the car's battery. But in those cases, the energy that's captured is the regular, predictable motion of braking. Zuo took that idea a step further, and designed a system of gears that collects the energy of irregular motion to ultimately produce electricity. He calls the device a mechanical motion rectifier, or MMR. "While working on vibration energy harvesting at large scale, I was thinking what is the fundamental challenge? What makes this different from the wind energy technology?" He told Discovery News. "It is the irregular velocity-alternating motion. Then we came up this MMR idea, to

It was possible because the Navy has opened a new Laboratory for Autonomous Systems Research (LASR) on the grounds of the Naval Research Laboratory, just across the Anacostia River from downtown. "This really is a one-of-a-kind laboratory that we expect will provide future sailors and Marines with better tools to do their jobs," Rear Adm. Matthew Klunder, chief of Naval Research, told reporters after the tour of LASR. "Under this one roof are all the environments our sailors and Marines could face," Klunder said. Klunder noted that the improved autonomous systems that will come out of the new facility fit nicely with the new national strategic directive that focuses the U.S. military's efforts on the Asia-Pacific region and the "anti-access, area-denial threat." Although the admiral did not say it, that A2AD threat is poised primarily by China, although Iran is attempting to achieve similar capabilities in the Persian Gul

Honda Motorcycle and Scooter India has launched the new daily commuter bike, Honda Dream Yuga at the Auto Expo. The bike is powered by a 110cc engine. It offers excellent mileage of 72 kmph. The bike will be available in May 2012. The bike will be available in three variants, kick/drum/spoke, kick/drum/alloy and self/drum/alloy. With the Dream Yuga 110, Honda has jumped into the budget end of the 110cc motorcycle spectrum. The bike looks quite similar to Honda’s 125cc commuter, the Shine and will come in five colour options. Specification: Engine: 4 stroke , Air cooled SI engine Displacement: 109cc Power: 9 bhp at 8000 rpm Torque: 9 Nm at 6000 rpm Gears: 4 speed , 1Dn , 4Up Battery: 12V maintenance free Tough frame Wheels: Spoked/Alloy Brake: Front Disc , Rear Drum Tyres: Tubeless tyres with optional Tuff up tubes Weight: 108 Kilograms Fuel Capacity: 9 liters Price: between Rs 40000 – Rs 45000
