GoKawiilNissan details third-generation e-POWER engine with STARC combustion tech
Nissan has outlined technical details of its new ZR15DDTe engine for third-generation e-POWER vehicles, built around a proprietary combustion concept called STARC paired with a large turbocharger. The design uses cold spray technology to shape intake ports and a specially contoured piston crown to control airflow toward the spark plug, aiming to stabilize combustion even at high exhaust gas recirculation rates.
GoKawiil's interpretation of the reporting above, not reported fact.
Improved combustion stability and thermal efficiency could translate into better fuel economy and power output for Nissan's hybrid lineup, which relies on e-POWER as its core electrification strategy rather than plug-in or full EV architectures in many markets. The emphasis on turbocharging alongside efficiency gains suggests Nissan is trying to close the gap between hybrid efficiency and higher performance expectations from consumers.
- Nissan's ZR15DDTe engine introduces the STARC combustion concept for third-gen e-POWER vehicles.
- Cold spray technology and reshaped intake ports/piston crowns aim to improve airflow and ignition stability.
- A large turbocharger is used to boost both output and thermal efficiency.
