Natural gas spark ignition engine efficiency and NOx emission improvement using extreme exhaust gas recirculation enabled by partial reforming

Instead of developing as a sphere, as in simulations, the kernel develops with a toroidal shape, then with a third-lobe structure, without relaxing toward a spherical shape even

Indeed, on top of using a low-pressure EGR circuit configuration (which substantially increases the transport lag compared to high-pressure configuration studied in Stotsky

Considering that the trapped mass is not a direct experimental observation, but results from an a posteriori analysis of individual experimental cycles that introduces

band structure. Emission from deeper lying core levels represents still another area for which the ARCIS can have special utility since the initial energy window for the

Abstract.- Preliminary measurements are reported of precision Dielectric Constant Gas Thermometry using helium between 4 and 27 K.. Values are given for the third density

for any compact ^-dimensional Riemannian manifold M where A runs over all open subsets with not more than half of the total volume, and it is known from geometric measure theory that

The object of this note is to explain how the theorem of Tate may be treated by means of normalized solution
