Walmart Trials Opposed-Piston Diesel Engine in Heavy-Duty Trucks

Walmart has started testing a new opposed-piston diesel engine in its heavy-duty truck fleet, aiming to cut emissions to near-zero levels without sacrificing performance. This engine design, which uses two pistons per cylinder moving toward each other, promises better fuel efficiency and lower emissions compared to conventional diesel engines.

The move is part of Walmart’s broader sustainability efforts, as the retail giant looks to reduce its carbon footprint in logistics. While electric trucks are gaining attention, diesel remains crucial for long-haul routes, and innovations like this could bridge the gap until zero-emission technologies mature.
