first_imgWhy does your hatchback, sedan or SUV give you a mileage different from what the car manufacturer claims under test conditions?This question made a Mizoram University professor and a research scholar invent a measuring device that yields a near-accurate mileage of a car per litre of fuel. Theirs is one of 25 patents applied for by teachers and research scholars of the university at Tanhril, about 15 km from State capital Aizawl.“Accurate knowledge of automobile mileage is crucial as it is an important performance index parameter of a vehicle during on-road operation. But the mileage achieved by a vehicle during actual road transport applications generally deviates from the manufacturer specifications under controlled conditions for a few driving cycles,” Hranghmingthanga, a professor in Mizoram University’s Department of Physics, told The Hindu.He and research scholar L. Lalnunthari worked on a mechanism that, unlike laboratory measurement, took into account factors such as road condition, driving style, traffic congestion, fuel quality used, gradients, and load on the vehicle.The inexpensive device entailing a digital multimeter, a pipe, and a calibrated fuel container was tested on an 800 cc petrol hatchback under conditions experienced by drivers on the road. “The margin of error in measuring the accurate mileage in kilometres per litre was 10%,” said Mr. Hranghmingthanga said.The device can be used for measurement when the car is stationary. “We can do the reading before starting the engine and after the ignition is switched off at the end of a trip,” said Ms. Lalnunthari.The duo declined to get into the details of their invention expected to be elaborated upon in a science journal soon. “It would suffice to say that it is intended to help vehicle manufacturers give the true average mileage and possibly work on more fuel-efficient engines,” said Mr. Hranghmingthanga.“Our university has had a tremendous year with applications filed for 25 patents by various departments. We have also attracted projects worth more than ₹40 lakh, and our aim is to be a topper among higher education institutes in the country,” said Mizoram University Vice-Chancellor K.R.S. Sambasiva Rao said.last_img read more


first_imgAll India Congress Committee’s Punjab in-charge Asha Kumari on Tuesday sought a report from the party’s State unit over the face-off between Chief Minister Amarinder Singh and his Cabinet colleague Navjot Singh Sidhu. Mr. Sidhu is under fire from his own party leaders after during electioneering he questioned as to why no FIR was lodged against the Badals for the desecration of religious texts in 2015. “We seek a report on every event, and in this issue too a report has been sought from the PCC,” Ms. Kumari said. She said the State party chief Sunil Jakhar, who is seeking re-election from Gurdaspur, will give the report once he is free from the election process after the declaration of the results.Captain Amarinder on Sunday had accused Mr. Sidhu of “damaging” the party in the State and suggested that he wanted to be the CM himself.Support for CM Meanwhile, more party leaders came out in support of the Chief Minister. “Amarinder Singh is an undisputed leader of Punjab. There are many facets to his personality,” said former Union Minister and party leader Manish Tewari. He praised Capt. Amarinder as a “protector of Punjab’s waters”, a writer, an able administrator who has a mass appeal. Jails Minister Sukhjinder Singh Randhawa also hit out at the Local Bodies Minister, saying, “Making such a statement during elections meant directly helping the Badals.” He added that Mr. Sidhu should know that it was Amarinder Singh who fought against the Badals and ensured the Congress victory in the 2017 Assembly polls. “In the 2017 Assembly polls, the Congress came to power in Punjab with an overwhelming majority as people voted in Amarinder Singh’s name. The party high command is with the Chief Minister. Our party has never tolerated indiscipline,” Mr. Randhawa said.Mr. Randhawa also alleged that when Mr. Sidhu’s wife, Navjot Kaur, was a BJP MLA, she never spoke on the desecration issue.‘Unease in ranks’ Union Minister of State for Housing and Urban Affairs Hardeep Singh Puri, who is the BJP’s Lok Sabha candidate from Amritsar, took a jibe at the Congress, saying, “All along the campaign, one could sense unease in their ranks.” “Now the cat is out of the bag,” he tweeted.last_img read more
