With intake or exhaust (or both) valve deactivation in place, inactive cylinders are prevented from pumping air through the engine, which enables effective use of three-way catalyst technology. With combustion occurring preferentially in this regime, the engine combustion system can potentially be optimized to match this operating area.

liter, naturally-aspirated, in-line four-cylinder direct-injection Isuzu diesel engine. However, there is an increase in NO 2 in the exhaust gas. Resources. Combustion characteristics are also analyzed to relate to the changes in particulate and NO x. —Tsang et al. The team conducted experiments on a 4.3-liter,

They found that the level of emissions of regulated and unregulated pollutants in diesel exhaust depends on fuel, load, engine calibration, and exhaust aftertreatment technology. Information pertaining to these emissions in diesel engine exhaust is much less complete than that for the regulated pollutants. —Chin et al.

Its basic operating mechanism is to apply combinations of very early or late injection timing, high injection pressure, low compression ratio, and high exhaust gas recirculation (EGR) levels to achieve a separation between the end of injection and the start of combustion, so that a premixed charge can be achieved before ignition occurs.
