(liquefied natural gas) in a large based-load plant near gas reservoir. The liquefaction of natural gas is different in thermodynamic structure from that of other cryogenic gases, such as air (nitrogen and oxygen), hydrogen, or helium[1,2], as illustrated inFig. 1. In general, a ...
2,3 The locally moist and warm atmosphere within the turbulent gas cloud allows the contained droplets to evade evaporation for much longer than occurs with isolated droplets. Under these conditions, the lifetime of a droplet could be considerably extended by a factor of up to 1000, from a ...

Most newEGR systemstend to use an electronic EGR valve to manage recirculation of exhaust gas. The EGR valve is closed when the engine is idling while there is no EGR flow into the manifold. When the engine becomes warm but still under load, the EGR valve starts to open. As the load ...
propulsion engine and contributes to faster catalyst warm-up. Fuel-fired air heaters are classically used in the cabs of commercial vehicles as preheaters during waiting and rest periods and night stops. This is confirmed by measurements of air temperatures at the air intake of a small van in ...
