Fuel Consumption and Emissions Reductions of Hybrid Electric Regional‐Haul Trucks Equipped with a High‐Pressure Direct Injection Natural Gas Engine in Real‐World Driving Conditions

Energy Technology, Volume 14, Issue 4, April 2026.
Integrating powertrain electrification with efficient engines using low‐carbon fuels like natural gas (NG) improves energy conversion efficiency and mitigates greenhouse gas (GHG) emissions in heavy‐duty (HD) trucks. High‐pressure direct injection (HPDI) NG engines, using less than 5% diesel (energy basis) as pilot fuel, offer diesel‐like efficiency ...
