Abstract:
A large fraction of diesel engine tailpipe NOx emissions are emitted before the aftertreatment components reach effective operating temperatures. As a result, it is essential to develop technologies to accelerate initial aftertreatment system warm-up. This study investigates the use of early exhaust valve opening (EEVO) and its combination with negative valve overlap to achieve internal exhaust gas recirculation (iEGR), for aftertreatment thermal management, both at steady state loaded idle operation and over a heavy-duty federal test procedure (HD-FTP) drive cycle. The results demonstrate tha

Abstract:
The competition to deliver fuel efficient and environmentally friendly vehicles is driving the automotive industry to consider even more complex powertrain systems. Adequate performance of these new highly interactive systems can no longer be obtained through traditional approaches, which are intensive in hardware use and final control software calibration.

Abstract:
The consumption of fossil and especially alternative fuels from renewable sources is supposed to rise in the future. Biofuels as well as fossil fuels often contain alkali and alkaline earth metal impurities that are potential poisons for automotive exhaust catalysts. The impact of these contaminations on the long-time performance of the exhaust aftertreatment system is a major concern. However, engine test bench studies consume considerable amounts of fuel, manpower and time. The purpose of this research project was to examine whether accelerated engine tests can be achieved by a modified dies

Abstract:
Highly transient engine-out emissions imply significant challenges for the optimization and control of automotive aftertreatment systems, motivating studies of the effects of flow pulsations on the system behavior. In this work, an axisymmetric aftertreatment system with a first-order reaction in the monolith section is chosen to demonstrate the role of pulsations on the time-averaged conversion at the exit. Reactive computational fluid dynamics simulations under transient conditions are performed by applying the SST k-ω turbulence model along with a reactant species balance equation and a por

Abstract:
Garrett Automotive Group is developing an exhaust aftertreatment system aimed at particulate emissions reduction from commercial diesel engines. The system uses a ceramic wall flow filter to trap the particulates, and regeneration is effected by raising gas temperature by throttling the exhaust downstream of the turbocharger. Lab testing at steady conditions demonstrated good performance with both catalyzed and uncatalyzed traps. Road testing shows the regeneration must be accomplished under severe transient conditions created by the normal vehicle operating modes. Primary efforts are to accom

Abstract:
Aftertreatment thermal management is critical for regulating emissions in modern diesel engines. Elevated engine-out temperatures and mass flows are effective at increasing the temperature of an aftertreatment system to enable efficient emission reduction. In this effort, experiments and analysis demonstrated that increasing the idle speed, while maintaining the same idle load, enables improved aftertreatment “warm-up” performance with engine-out NOx and particulate matter levels no higher than a state-of-the-art thermal calibration at conventional idle operation (800 rpm and 1.3 bar brake mea

Performance tests were conducted on a low-emission combustor, which has a pre-vaporization–premixing lean combustion system and is designed for a 100 kW automotive ceramic gas turbine. The results of steady-state combustion tests performed at an inlet temperature of 1000–1200 K and pressure of 0.1–0.34 MPa indicate that the combustor would meet Japan’s emission standards for gasoline engine passenger cars without using an aftertreatment system. Flashback was suppressed by controlling the mixture velocity and air ratios. Strength tests conducted on rings and bars cut from the actual ceramic par

Abstract:
Automotive diesel engines, thanks to their high efficiency, play a key role in the future global CO2 emission reduction. However, the upcoming tighter regulations with the aim of reduction of the harmful pollutant emissions require the adoption of more complex after-treatment systems, where the integration between different components is mandatory in order to minimize the overall drawbacks and maximize the system efficiency. In particular, in this work a Diesel Particulate Filter (DPF) and a Diesel Oxidation Catalyst (DOC) were experimentally and numerically investigated, considering both the
