New Bosch tech makes diesel engines far less polluting German engineering firm Bosch has developed technology that uses currently available hardware to drastically bring down nitrous oxide (NOx) emission in diesel cars. The sales of diesel cars have tumbled in the recent months as regulators aim to lower the output of NOx; the gas is harmful to humans and is associated with respiratory problems in urban environments. Bosch claims that it has developed a solution that not only reduces NOx output in diesel engines but practically eliminates it so it falls to a point that’s almost a tenth of the next-generation limits. “We call our system active thermal management because it keeps the most important part of the diesel exhaust, the exhaust gas recirculation (EGR) system, running at its optimal temperature,” Bosch diesel division development boss Michael Krüger told our sister publication Autocar UK. EGRs work best when they are heated by waste gases to more than 200degC, but Krü...

The Countries With The Highest Density Of Industrial Robots  Across the world, the pace of industrial automation is steadily accelerating. According to  the International Federation of Robotics , there were 66 installed industrial robots per 10,000 employees globally in 2015 and that increased to 74 in 2016. Broken down by region, average robot density in Europe is 99 units per 10,000 workers, while's it's 84 in the Americas and 63 in Asia. Even though China has recorded the most dynamic development of robot density in recent years, South Korea has the highest level of density of any country on the planet. In 2016, South Korea had 631 industrial robots per 10,000 employees and that's primarily due to the continued installation of high volume robots in the electronics and manufacturing sectors. Singapore comes second with 488 robots per 10,000 employees, 90 percent of which are installed in its electronics industry. In Germany and Japan, two countries renowned for th...

Scientists find use of fly ash in mosquito control Fly ash, a harmful byproduct of coal-based power generation, has found a new use - mosquito control. Scientists at Vector Control Research Centre (VCRC) of the Indian Council of Medical Research (ICMR) and Pondicherry University have successfully used fly ash as a carrier for  Bacillus Thuringiensis Israelensis  (Bti), a bio-pesticide used for killing larvae of many insects. The results of the study have been published in  Indian Journal of Medical Research . The researchers have found Bti formulation containing fly ash as carrier and 1 per cent carboxymethyl cellulose as additive to be effective against mosquito larvae. Bti is mainly derived from microbial cultures and is known to produce proteins that act against pests of agriculture and medical importance. Its use against mosquitoes responsible for transmitting malaria, dengue, yellow fever and filariasis has picked a great deal in recent years. It is consi...

a subsidiary of Hyundai Motor Group that manufactures automotive parts in South Korea, has opened a 3D printing lab, the Design Model Workshop, which has the capacity to 3D print customized vehicle parts. It is South Korea’s first design research facility launched by an automotive component supplier. Prototyping 3D printed parts on clay models The workshop is the result of a $2.8 million investment from Hyundai Mobis. The lab occupies 430 square meters at Hyundai’s Mabuk Technical Center, in Yongin, South Korea. The facility is equipped with a powder 3D printer, as well as a range of cutting-edge design machines, including a clay model processing machine, which is capable of creating full-size clay vehicles. The clay model processing machine takes three weeks to produce a full-size car model, accurate to 0.05mm. This is a subtractive process, where a robot arm cuts into a block of clay before color and texture are added, creating a model visually identical to the actual car to ...

Boeing and Rolls-Royce have invested £26.5 million (approx. $37.6 million) in  Reaction Engines Limited , a UK-based aerospace company working on the  3D printing enabled SABRE engine  and future  hypersonic travel . Capable of Mach 5.4 and Mach 25 speeds, the Synergetic Air-Breathing Rocket Engine (SABRE) travels at 5.4 and 25 times the speed of sound, making military response or long-haul flights a breeze. Steve Nordlund, Vice President of Boeing investment arm HorizonX comments, “We continue to connect capabilities around the globe with our investment in Reaction Engines, which is our first in a UK-based company,” “AS REACTION ENGINES UNLOCKS ADVANCED PROPULSION THAT COULD CHANGE THE FUTURE OF AIR AND SPACE TRAVEL, WE EXPECT TO LEVERAGE THEIR REVOLUTIONARY TECHNOLOGY TO SUPPORT BOEING’S PURSUIT OF HYPERSONIC FLIGHT.” A $142 million project Reaction Engines was formed in 1989 “to design and develop the technologies needed for a new class of inn...

World's one of the biggest engine :- Shipping goods from China to the U.S. is big business. And when we say big, we're talking 1,300-foot-long ships that weigh 170,974 tons. The cargo ships in question can carry 11,000 20-foot shipping containers at a breakneck speed of 31 knots.  That's a lot more oomph than the typical 20-knot cruiser, and the reason for the extra push is the world's largest  diesel  engine. The 109,000-horsepower Wärtsilä-Sulzer RTA96-C, which first set sail in the Emma Mærsk in 2006, weighs in at a rotund 2,300 tons, and it's 44-feet tall and 90-feet long. In other words, the TRA96 is the height of a four-story building, and longer than a Christmas Eve line at Sam's Club. Within that massive exterior rests 14 cylinders that each consume 6.5-ounces of diesel fuel every cycle. And, if you like torque, there's enough twist to rip an M1 tank to shreds, though the massive mill churns at only 102 rpm.  That's a lot of motor to ponde...
