The jumping off point for the\u00a0<a href=\"https:\/\/www.hydrogenfuelnews.com\/hydrogen-cars-bmw-zipse\/8555643\/\">H2 drivetrain<\/a>\u00a0was the digital data set for its gasoline-powered counterpart. This was used as a benchmark that must be matched as a minimum by the H2 version.\n\nModifications to the conventional internal combustion engine included a higher compression ratio and combustion alternations to make it appropriate for H2 gas. It also includes a newly designed\u00a0<a href=\"https:\/\/hydrogen-central.com\/porsche-hydrogen-engine-beats-v8s-topauto\/\">turbocharging system<\/a>.\n\nTo be able to achieve clean\u00a0<a href=\"https:\/\/www.hydrogenfuelnews.com\/hydrogen-combustion-engine-toyota-2\/8556753\/\">H2 combustion<\/a>, the turbochargers are required to offer about twice the air mass as is needed in a comparable gasoline-powered model. That said, the design was also required to compensate for lower gas temperatures with the alternative fuel, as this could cause a lack of propulsion energy.\n\nTraditional turbochargers don\u2019t have the capacity to resolve that issue, therefore Porsche Engineering was required to develop alternatives. In fact, they came up with four new turbocharging concepts.\n\nEach of the alternative systems consisted of a number of electrically supported turbochargers. Additional control valves were added some within their electrically powered compressors and their air systems. Each of the alternative configurations had its own advantages and disadvantages according to the automaker. The best option has a heavy dependence on the hydrogen engine\u2019s use. Back-to-back compressors were an important part of the design that rivalled the gasoline-powered model.\n\n\u201cThe special feature of this design is the coaxial arrangement of two compressor stages, which are driven by the turbine or the supporting electric motor using a common shaft,\u201d said a statement issued by\u00a0<a href=\"https:\/\/en.wikipedia.org\/wiki\/Porsche\">Porsche<\/a>. \u201cThe process air flows through the first compressor, is cooled in the intercooler, and then recompressed in the second stage.\u201d\n\nThis allowed the hydrogen engine to achieve a 440kW maximum output as well as a top speed of 261km\/h, aligning well with gasoline powered V8 engines.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"<p>Porsche hydrogen
