Biology, Pathobiology and Gene Therapy of CNG Channel-Related Retinopathies

Biomedicines, 2023
The visual process begins with the absorption of photons by photopigments of cone and rod photoreceptors in the retina. In this process, the signal is first amplified by a cyclic guanosine monophosphate (cGMP)-based signaling cascade and then converted ...

Comparative assessment of the performance and combustion attributes of a free piston linear generator fuelled with CNG and CNG-CO2

Case Studies in Thermal Engineering, 2022
A free-piston linear generator (FPLG) is an energy conversion device that can generate electrical energy utilizing different types of fuel. Natural gas fields with high carbon dioxide (CO2) content are being simulated for study, knowing that the presence

An Experimental Study on the Performance and Emission of the diesel/CNG Dual-Fuel Combustion Mode in a Stationary CI Engine

Energies, 2019
One of the possibilities to reduce diesel fuel consumption and at the same time reduce the emission of diesel engines, is the use of alternative gaseous fuels, so far most commonly used to power spark ignition engines.

Evaluation of real-world emissions of China V heavy-duty vehicles fueled by diesel, CNG and LNG on various road types.

Chemosphere, 2022
Natural gas has been widely considered as an alternative fuel to diesel on heavy-duty vehicles (HDVs). To evaluate the real-world emissions, 19 diesel HDVs, 3 CNG HDVs and 9 LNG HDVs were tested using portable emission measurement system on urban ...

Spark ignition engine performance, standard emissions and particulates using GDI, PFI-CNG and DI-CNG systems

Fuel, 2021
Gaseous fuels, e.g., natural gas, biogas, have several advantages over liquid fuels owing to their favorable physical and chemical properties, e.g., lower carbon numbers in the fuel composition and no issues regarding fuel evaporation.
