Optimized heavy-duty CI engine fueled with DME delivers diesel performance, significantly reduces engine-out emissions

Green Car Congress

With the most recent design, an increase of the efficiency level of around 1–2 percent-points can be expected. The engine was also equipped with an electrically driven volumetric pump in the exhaust gas recirculation (EGR) path which gives the freedom to set any desired EGR rate, independently from the pressure ratios across the turbocharger.

Rolls-Royce successfully tests 12-cylinder mtu engine with pure hydrogen

Green Car Congress

Rolls-Royce has conducted successful tests of a 12-cylinder gas variant of the mtu Series 4000 L64 engine running on 100% hydrogen fuel. For several months, the mtu gas engine has been undergoing bench testing and continuous improvement in terms of efficiency, performance, emissions and combustion using 100% hydrogen as fuel.

IAV develops new close-coupled diesel exhaust gas aftertreatment system for improved emissions reduction

Green Car Congress

IAV has developed a particularly closed-coupled diesel exhaust gas aftertreatment (EAT) system. A key contribution to this performance must come from the exhaust gas aftertreatment system—across the entire speed and load range. This way, exhaust gas flows through DOC and SCRF before it enters the turbine.

Amminex City-SCR upgrade delivers gaseous ammonia for improved SCR conversion of NOx; avoiding high off-cycle emissions

Green Car Congress

Studies have found that despite meeting more stringent regulatory standards for exhaust emissions during type approval, many vehicles equipped with selective catalytic reduction (SCR) systems have significantly elevated emissions of NO x during in-use driving—particularly when operating in urban traffic. —Lowell and Kamakaté.
