Exhaust and aftertreatment on the Achates ULNOx heavy-duty opposed-piston diesel

Green Car Congress

opposed-piston (OP) heavy-duty diesel engine achieved Ultralow NO x (ULNO x ) performance results. A key element of the achievement is the low engine-out NO x from the opposed-piston engine, which reduced the requirements for the aftertreatment system (ATS). Earlier post.) The OP engine operates at nearly ideal temperature range.

Use of a Low-Cost Electric Supercharger Could Significantly Reduce Smoke from Turbocharged Diesel Engines

Green Car Congress

It is commercializing three initial products: Variable Torque Enhancement System, VTES, an electric supercharging system; SpeedStart12, an integrated belt-driven starter generator system; and TIGERS, an exhaust turbine-driven generator system. It can also help minimize the need for expensive exhaust after-treatment. Click to enlarge.

IPG to demo Flameless Ceramic Turbine for clean, off-grid power in EV charging

Green Car Congress

But, in many high-use areas and remote locations, upgrading grid connections to meet future charging demand is not practical or commercially viable. Low-cost ceramics enable temperatures beyond the limitations of metals to deliver fuel efficiencies of power plants in small-scale distributed power.
