  • Internal Combustion Engines
  • Catalyst Heating
  • Cold Start

The world is undergoing strong environmental challenges that force automobile manufacturers to take immediate action to reduce the amount of greenhouse gas emissions in addition to the health threatening pollutants. With that in mind, regulations on vehicle emissions are continuously updated. One such example is the current EURO 6 regulation, which will soon be updated to the EURO 7. These new demands require research and development of cleaner internal combustion engines (ICE), as this technology will still be present both in pure ICE automobiles and hybrid ones in the near future.

In real-world driving cycles, a large source of pollutant emissions happens on the cold start phase. These operating points are characterized by lower coolant and oil temperatures which lead to imperfect fuel-air mixing and combustion processes. It is also in this stage that exhaust catalytic converters are heated to their operating temperatures, an operation that requires unorthodox combustion strategies. Within this context, cold start operating points taking into account catalyst heating strategies are researched.

Additionally, the experiments are carried in a quasi-full metal single-cylinder engine with endoscopic access and minimal optical invasion. Compared to fully optically accessible engines, this allows for longer operating times and a closer geometry to real production engines.

With the fast development of the world, it is important to further understand the complex engine flow and combustion phenomena. Through the above-mentioned tools and context, it is possible to achieve such objectives and consequently pave the way to a sustainable future.
