چکیده
Commercial vehicles require fast aftertreatment heat-up to move the SCR catalyst into most efficient temperature range meet upcoming NO X regulations while minimizing CO 2 . One solution this challenge is add a fuel burner upstream of con`ventional heavy-duty diesel system. The focus paper optimize based thermal management approach. objective included complying with CARB’s 2027 low emissions standards for on-road heavy duty engines. This was accomplished by pairing system cylinder de-activation on engine and/or light-off sub-system. A demonstrated using an aged targeted emission levels various controls. baseline layer controls includes deactivation raise exhaust more than 100°C in combination elevated idle speed increase mass flowrate through operating burner, and (during cold start) allows heat up small fraction time today’s systems. Performance quantified over FTP, hot load cycle (LLC) U.S. beverage cycle. improvement reduction savings these cycles are highlighted.

BURNER TECHNOLOGY FOR SINGLE DIGIT NOx EMISSIONS IN BOILER APPLICATIONS
The local air quality districts in the Los Angeles area were the first to implement restrictions to require that NOx emissions on natural gas fired boilers be reduced to single digit levels. Now additional states are being required to develop State Implementation Plans (SIPs) to address bringing into compliance the areas that do not meet the ozone standards set forth in the Clean Air Act Amendm...
متن کاملFixpoint Computation: Leaking Gas Burner
Real-time distributed system speciication and veriication in asynchronous propositional temporal logic. Let A be the integrator system deened in Figure 5. We use the xpoint computation procedure to prove that the formula y 60 ! 20t y is an invariant of A. It follows that the gas burner leaks at most one twentieth of the time in any interval of at least 60 seconds. Let R i = hpc = 1 ^ t = 0 ^ x ...
متن کاملExperimental and numerical investigations in the near-burner region of a versatile multi-fuel burner
An experimental and numerical investigation on the effect of swirl on the motion of coal particles in the near-burner region of a versatile multi-fuel swirl-stabilised laboratory burner of total thermal input of 100kW, has been performed. The burner was designed as a scale model of a lOMW coal burner operating in a cement rotary kiln, produces flames of different aerodynamic characteristics, an...
متن کاملRayleigh Scattering Temperature Measurements in a Swirl Stabilized Burner Original Citation Rayleigh Scattering Temperature Measurements in a Swirl Stabilized Burner
Rayleigh scattering temperature measurements were obtained in a turbulent reactive swirling coaxial jet discharged from a swirl-stabilized burner along the jet-flame centerline. They are reported up to 10 fuel nozzle diameters downstream of the burner exit at a Reynolds number of 29000. The effect of swirl numbers (S=0.3, 0.58, 1.07) on the temperature fields, the power spectral density of temp...
