A study by researchers at The Hong Kong Polytechnic University and Tianjin University has found that the use of fumigation ethanol in a 4-cylinder diesel decreases NO x , smoke and particulate mass and number concentrations. In addition, the diesel fuel used in previous research has a high sulfur content of 0.25% by weight.

It is generally agreed that very high injection pressures are needed to improve engine thermal efficiency fuel economy, lower heat rejection, and to minimize exhaust aftertreatment complexity and costs. Millions of this type of injector have been used since the mid 1990s by Navistar, Ford, Caterpillar, and Isuzu.).

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.

Furthermore, and in relation to exhaust emission requirements, the manufacturers agreed to recommend the introduction of legislative requirements regarding market fuels, in order to ensure that the appropriate, high-quality fossil and renewable fuels are globally available for today’s vehicle technologies.
