Augmented Reality Windshields?

Augmented Reality Windshields?

Photo: Some rights reserved by dvanzuijlekom Imagine your car’s entire windshield working like Google Glass. Instead of peering through dust and grime to see the boring real world of traffic, you would see cars and key road features deeply integrated with data—colorfully highlighted and annotated for greater safety, convenience and enjoyment. Imagine the scenario: you’re driving along an unfamiliar road at night, and suddenly the car flashes up a warning directly in front of you on the road. It’s the same size, shape, and position as the deer lurking on the verge, allowing you to quickly identify the danger ahead … Continue reading

Most Drivers Don’t Use Car Tech?

Most Drivers Don’t Use Car Tech?

Photo: Some rights reserved by ** RCB ** The Los Angeles Times notes that 43 percent of people surveyed don’t use their cars’ voice recognition to call up things like GPS directions. Thirty-five percent never tried automatic parking, 32 percent avoided apps like Yelp, and 20 percent didn’t even use half of the tech features in their cars. (The survey asked about 33 tech features that seemed to be available in all respondents’ cars.) The report polled 4,200 people between April and June who had bought or leased cars no more than three months before taking the survey. Research … Continue reading

Radiators And What They Do

Radiators And What They Do

Photo: Some rights reserved by andrewasmith Radiators are heat exchangers used to transfer thermal energy from one medium to another for the purpose of cooling and heating. The majority of radiators are constructed to function in automobiles, buildings, and electronics. The radiator is always a source of heat to its environment, although this may be for either the purpose of heating this environment, or for cooling the fluid or coolant supplied to it, as for engine cooling. Despite the name, most radiators transfer the bulk of their heat via convection instead of thermal radiation (the main exception to this … Continue reading

Vehicle Wireless Fixes For High Tech Cars

Vehicle Wireless Fixes For High Tech Cars

Photo: Some rights reserved by Robert Scoble As cars increasingly resemble digital devices, a group of technology firms that can send wireless software updates to cars are in hot demand by carmakers scrambling to catch up to Tesla Motors (TSLA.O) in the arena of over-the-air updates, or OTAs. Interest in the technology, through which certain car functions can be upgraded much the same way as an iPhone, comes as Tesla is set to deliver an OTA for hands-free cruise control this month, allowing its electric Model S sedans to drive themselves on freeways. “Tesla has made great strides in … Continue reading

Cities Must Prepare For Self-Driving Cars

Cities Must Prepare For Self-Driving Cars

Photo: Some rights reserved by jaumescar The motoring industry has long bragged that the cars of the near future will be driverless, but it seems someone forgot to mention it to the world’s cities. For autonomous driving to become a reality, there’s an enormous amount of infrastructure (and legislation) that needs to be in place beforehand, but a new study’s revealed that 94 per cent of the world’s cities are failing to prepare. Change is coming fast. Seven auto manufacturers and technology companies including Cadillac, Tesla, Google, Volvo, Audi, Mercedes-Benz and Nissan have said they expect to bring driverless … Continue reading

What Is Coolant/Antifreeze?

What Is Coolant/Antifreeze?

Photo: Some rights reserved by lungstruck A coolant is a fluid which flows through or around a device to prevent the device from overheating, transferring the heat produced by the device to other devices that either use or dissipate it. An ideal coolant has high thermal capacity, low viscosity, is low-cost, non-toxic, chemically inert, and neither causes nor promotes corrosion of the cooling system. Some applications also require the coolant to be an electrical insulator. While the term coolant is commonly used in automotive and HVAC applications, in industrial processing heat transfer fluid is one technical term more often … Continue reading

More on Your Car’s Water Pump

Photo: Some rights reserved by Gh0stman The water pump in a car engine isn’t a complicated piece of machinery, despite its vital importance to the car’s ability to run efficiently without breaking down. Its role is to circulate water and coolant around the engine in order to keep its overall temperature, especially around the cylinder head and engine block, as low as possible when it is running. The higher the load on the engine, the more coolant will be circulated around it in order to deal with the greater levels of heat being produced. The pump circulates coolant via … Continue reading

Reminder of How Cooling Systems Work

Reminder of How Cooling Systems Work

Photo: Some rights reserved by 4eyesLouer Have you ever considered the thousands of times explosions occur in your engine? If you’re like most people, that thought never enters your mind. Every time a spark plug fires, the fuel and air mixture in that cylinder blows up. It happens hundreds of times per cylinder per minute. Can you imagine how much heat that generates? Those explosions are relatively small, but in sheer quantity they produce extreme heat. Consider an ambient air temperature of 70 degrees. If an engine is 70 degrees “cold,” how long after it’s started is the whole … Continue reading

Reminder On How Radiators Work

Photo: Some rights reserved by Sicnag Radiators are heat exchangers used for cooling internal combustion engines, mainly in automobiles but also in piston-engined aircraft, railway locomotives, motorcycles, stationary generating plant or any similar use of such an engine. Internal combustion engines are often cooled by circulating a liquid called engine coolant through the engine block, where it is heated, then through a radiator where it loses heat to the atmosphere, and then returned to the engine. Engine coolant is usually water-based, but may also be oil. It is common to employ a water pump to force the engine coolant … Continue reading
