Engine Research Lab

 

Our expertise

At the UNSW Engine Research Laboratory, we experimentally investigate internal combustion engine technologies, fuel injection and sprays, combustion regimes and alternative fuels. We are specialists in optical/laser-based imaging diagnostics that are used to show the inner workings of engines and to clarify flow fields, turbulence, mixing, reaction and pollutant formation processes occurring inside the cylinder of the engine. We also conduct systematic performance and emissions testing to optimise multiple operating parameters for efficiency improvement and emission reduction.

Research Areas

  • Fundamentals of engine combustion and pollutants formation

We clarify physical mechanism responsible for mixing and combustion processes in internal combustion engines. Advanced optical/laser-based imaging diagnostics are performed to obtain a detailed understanding of complex reaction and pollutants formation processes occuring inside the engine room. This scientific approach leads to the development of new combustion regimes such as gasoline compression ignition (GCI) and low-temperature-combustion (LTC) diesel that can achieve dramatic emissions reduction and efficiency gain.

  • Alternative fuels combustion

Through the laser-based diagnostics and parametric engine performance tests, we can assess how differently alternative fuels burn in an engine. More importantly, various fuel compositions enable us to study the molecular structure effect on emissions formation process. As there are an increasing number of fuel options available, increasing demands on combustion research are expected.

  • Fuel injection and spray

The fuel injection system is a key factor to optimise the engine-out emissions as well as the efficiency. Indeed, all of recent innovations made in internal combustion engines involved a new kind of fuel injection systems. We image the spray development and its interaction with the combustion chamber so that scientific background for the best performance of a particular design (or operating condition) can be provided.

  • Fluid mechanics in an engine

The internal combustion engine offers very challenging fluid mechanics problems due to its highly turbulent and transient nature. Accordingly, limited data is available especially for the interactions between in-cylinder flow structures and flames. We are experts in measuring flow fields and providing the physical interpretation of the observed emissions trends.
