google driver less car


 The Google driver less car is a project by  google that involves developing technology for autonomous car. The software powering Google's cars is called Google Chauffeur. Lettering on the side of each car identifies it as a "self-driving car." The project is currently being led by Google engineer sebastian thrun director of the  SAILand co-inventor of google street view Thrun's team at Stanford created the robotic vehicle stanley which won the 2005 darpa grand challengr and its US$2 million prize from the united states department of defense The team developing the system consisted of 15 engineers working for Google, including Chris Urmson, Mike Montemerlo, and Anthony Levandowski who had worked on the  darpa grand and urban challenges
The U.S. state of nevada passed a law on June 29, 2011 permitting the operation of autonomous cars in Nevada. Google had been lobbying for robotic car laws. The Nevada law went into effect on March 1, 2012, and the nevada department of motor vehicles issued the first license for an autonomous car in May 2013. The license was issued to a Toyota Prius modified with Google's experimental driverless technology. As of April 2013, Florida became the second state to allow the testing of autonomous cars on public roads. California became the third state to legalize the use of self-driven cars for testing purposes as of September 2012 when Governor Jerry Brown signed the bill into law at Google HQ in Mountain View.

Electric pump

In many modern cars the fuel pump is usually electric and located inside the fuel tank. The pump creates positive pressure in the fuel lines, pushing the gasoline to the engine. The higher gasoline pressure raises the boiling point. Placing the pump in the tank puts the component least likely to handle gasoline vapor well (the pump itself) farthest from the engine, submersed in cool liquid. Another benefit to placing the pump inside the tank is that it is less likely to start a fire. Though electrical components (such as a fuel pump) can spark and ignite fuel vapors, liquid fuel will not explode and therefore submerging the pump in the tank is one of the safest places to put it. In most cars, the fuel pump delivers a constant flow of gasoline to the engine; fuel not used is returned to the tank. This further reduces the chance of the fuel boiling, since it is never kept close to the hot engine for too long.
The ignition switch does not carry the power to the fuel pump; instead, it activates a relay which will handle the higher current load. It is common for the fuel pump relay to become oxidized and cease functioning; this is much more common than the actual fuel pump failing. Modern engines utilize solid-state control which allows the fuel pressure to be controlled via pulse-width modulation of the pump voltage. This increases the life of the pump, allows a smaller and lighter device to be used, and reduces electrical load.
Cars with electronic fuel injection have an (ECU) and this may be programmed with safety logic that will shut the electric fuel pump off, even if the engine is running. In the event of a collision this will prevent fuel leaking from any ruptured fuel line. Additionally, cars may have aninertia switch (usually located underneath the front passenger seat) that is "tripped" in the event of an impact, or a roll-over valve that will shut off the fuel pump in case the car rolls over.
Some ECUs may also be programmed to shut off the fuel pump if they detect low or zero oil pressure, for instance if the engine has suffered a terminal failure (with the subsequent risk of fire in the engine compartment).
The fuel sending unit assembly may be a combination of the electric fuel pump, the filter, the strainer, and the electronic device used to measure the amount of fuel in the tank via a float attached to a sensor which sends data to the dash-mounted fuel gauge. The fuel pump by itself is a relatively inexpensive part. But a mechanic at a garage might have a preference to install the entire unit assembly.

Editorial Review of the New Hyundai Eon Magna +

Currently Hyundai is India's second largest manufacturer of cars and with the kind of new vehicles it has been rolling out, there is every possibility that their market share will soon be inching closer to that of Maruti. The new Eon for example is the perfect weapon with which the Korean giant will easily destroy the market share that the Alto enjoys.

Price is always the most important thing in the Indian market and the Eon plays this card perfectly well. Priced from Rs 2.69 lakh for the base version, it does provide  you awesome value for money. Even the top end model that comes with A/C, power steering, front power windows, integrated audio system and driver's air-bag sets you back by just Rs 3.71 lakh! And this pricing doesnt really come at the cost of the overall package for the Eon not looks the best in segment, it also has a class leading cabin with best quality and space.

On the engine front, the Eon might get a small 814cc engine but it has enough power to make it a good car for city. The icing on the cake is the best in class fuel economy!  The Eon surely looks all set to rival the Alto to be India's largest selling car soon
