Engine manufacturers typically rate their engines fuel consumption by the lower heating values since the exhaust is never condensed in the engine, and doing this allows them to publish more attractive numbers than are used in conventional power plant terms. The conventional power industry had used HHV (high heat value) exclusively for decades, even though virtually all of these plants did not condense exhaust either. American consumers should be aware that the co… WebPrecio del GNV – Gas Natural Vehicular en el Perú – Nivel Nacional (Actualizado hoy, Martes, 11 de abril del 2024) A continuación presentamos la información detallada y …
