Impressive news from the new Prototype CNG category late yesterday afternoon: team Microjoule-La Joliverie pulled off a 2,521km/litre equivalent first attempt (imagine driving from Rotterdam to Palermo on one litre). New category, new benchmark. The first UrbanConcept challenge started this morning. First on track was Louis Delage School from France with their gasoline car, pulling …
Image Credit:www.globalspec.com Some common boiler problems are described below: Fires Cleanliness of the heat recovery surfaces after the boiler can often be judged by observing the gas pressure differential above and below. Any significant rise in this value should be attended to. Whilst good combustion conditions will minimise the risk, deposits allowed to accumulate …
Heat Treatment Process from Mohammud Hanif Dewan M.Phil.
Image Credit: www.riceweightloss.com Older loop scavenged engines may have a single injector mounted centrally in the cylinder head. Because the exhaust valve is in the centre of the cylinder head on modern uniflow scavenged engines the fuel valves (2 or 3) are arranged around the periphery of the head. The pressure at which the injector …
