LPG ( Liquefied Petroleum Gas ) is predominantly propane with iso-butane and n-butane. It has one major advantage over CNG, the tanks do not have to be high pressure, and the fuel is stored as a liquid. The fuel offers most of the environmental benefits of CNG, including high octane - which means higher compression, more efficient, engines can be used. Approximately 20-25% more fuel than gasoline is required, unless the engine is optimised ( CR 12:1 ) for LPG, in which case there is no decrease in power or any significant increase in fuel consumption T.i. ja palielina dzineeja kompresijas pakaapi(CR -compression ratio), tad gaazi peec apjoma teeree tik pat cik benziinu? Ir kas taads dariits vai zinaams praksee? Nebuutu galiigi iipashu probleemu, ja nu vieniigi benziinu vajadzeetu kaut kaadu saciikshu variantu, toties tikai ljoooti nedaudz - iedarbinaashanai un varbuut apstaajoties, bet varbuut vispaar iztikt bez. Vienmeer esmu briiniijies, kaapeec gaaze ar augstaaku siltumspeeju nenodroshina taadu pat l/100km nobraucienu!
