\"The measurement process of compressed natural gas.\" (CNG) vehicle, designed to supply fleets of vehicles with identical fuel tanks.The quantity of CNG is supplied to the tanks can be set almost exactly without the use of flow meter.Is a standardized initial volume based on ambient ...
In order to eliminate the speed fluctuation of the compressed natural gas(CNG)/diesel dual fuel engine in the switch process from pure oil condition to dual fuel condition, the software algorithm was improved to realize the smooth transition with little change on the control system hardware. Based...

Upgrading is the process ofremoving carbon dioxideand other impurities from biogas and compressing it. It producesbiomethane– ahighly sought after product. It is sold asRenewableCNG(Compressed Natural Gas – a substitute for Liquefied Natural Gas)as a vehicle fuel, orinjected into the regional nat...
However, upscaling the batch process to semi-continuous operation mimics the full-scale operational conditions and provides a better picture of the process's feasibility and scalability. Moreover, the insight on different scenarios of biogas upgrading to bio-compressed natural gas (BioCNG), energy ...
The liner of a CNG pressure vessel is manufactured by a DDI (deep drawing and ironing) process for the cylinder part, which is a continuous process that includes a drawing process to reduce the diameter of the billet and a subsequent ironing process to reduce the thickness of the billet. A...
is dominantly used as a compressed natural gas (CNG) fuel, and the corresponding limit of O 2 content in the product gas is lower than 0.5 vol.% [17]. O 2 content determines the air–fuel ratio of the com- bustion process. If O ...

of liquefaction, the latent duty is reduced, improving the efficiency of the liquefaction cycle. LNG achieves a higher reduction in volume than compressed natural gas (CNG) so that the energy density of LNG is about 2.4 times greater than that of CNG and about 60% of that of diesel fuel....
(k) passing the compressed first vapor stream of step (f) through a second heat exchanger to still further cool the first vapor stream; (l) expanding the vapor stream of step (g) to decrease the pressure and to reduce the temperature; ...
