Driven by the desire to implement low-cost, high-efficiency NOx aftertreatment systems, such
as Three Way Catalysts (TWC) or Lean NOx Traps (LNT), a novel 6-Stroke engine cycle was …

Compression-ignition (CI) engines can produce higher thermal efficiency (TE) and thus
lower carbon dioxide (CO2) emissions than spark-ignition (SI) engines. Unfortunately, the …

This paper charts the development of three three-way catalyst (TWC) and four lean-NOx trap
(LNT) formulations in four vehicle systems over a four-year period. All LNTs were installed in …

Experimental investigations were conducted on a novel, Stoichiometric Compression
Ignition (SCI) combustion system designed to operate a diesel engine at stoichiometric …

Gasoline compression ignition (GCI) using a single gasoline-type fuel for direct/port injection
has been shown as a method to achieve low-temperature combustion with low engine-out …

Results from computational simulations of fuel economy and engine-out emissions are
presented for light-duty conventional and hybrid vehicles powered by conventional and high …

The recently concluded partnership for advancing combustion engines (PACE) was a US
Department of Energy consortium involving multiple national laboratories focused on …

In this experimental study, the Diesel fuel blends with different percentages of Ethanol and
Methanol with a constant percentage (5%) of n-Butanol were used. These percentages were …

The 2010 emission standards for heavy-duty engines have established a limit for oxides of
nitrogen (NOX) emissions of 0.20 g/bhp-hr, a 90 percent reduction from the previous …

Gasoline compression ignition (GCI) is a promising powertrain solution to simultaneously
address the increasingly stringent regulation of oxides of nitrogen (NOx) and a new focus on …
