The Webinar: Homogeneous vs Stratified Fuel Injection brought by Jérôme Carpentier as presenter to break down the real-world differences in how modern gasoline direct injection engines get the job done.

The session dove straight into the core of GDI engine operation, comparing stoichiometric homogeneous mixtures that deliver reliable performance and clean three-way catalyst efficiency with lean homogeneous setups that cut pumping losses and fuel use but risk knock and slower burn. The real game-changer came with lean stratified mode, where precise late-injection timing creates a concentrated fuel cloud near the plug for ultra-lean running—think 30-40% better fuel economy at idle and light loads. Presenters stressed how these strategies tackle emissions regs head-on while demanding smart airflow control, piston design, and EGR use to keep everything stable and clean. It all ties back to why shops and schools need equipment that shows these modes in action—students and techs walk away understanding exactly how today’s engines squeeze every drop of efficiency without guessing at fault codes or carbon issues.
