Combustion Engine Laboratories at Applied Mechanics/CERC
The Combustion Division within the Department of Applied Mechanics hosts an extensive set of engine labs. It includes six well equipped test cells where the engines under investigation can range from small two-strokes to automobile engines and up to heavy duty truck engines. They include single cylinder research engines and more production-like multi-cylinder engines.
A brand new test cell for hybrid electric vehicles (the full vehicle) includes 2 wheel dynamometers (2 more can be added for 4 wheel drive vehicles), control systems, an advanced battery simulator, and emissions monitoring equipment.
The lab also includes a dedicated cell for studies of fuel sprays. Various kinds of fuel are investigated, from single component research fuels up to biofuel blends, gasoline, and Diesel fuel. Two spray chambers are used; one at moderate pressure and room temperature and one at high pressure and temperature in which spray combustion can also be studied.
Measurement instrumentation includes conventional equipment for engine tests (e.g. engine dynamometers, sensors, fuel and gas flows, emissions measurements, and data acquisition and processing) together with advanced optical and laser-based measurement equipment. Examples include a spectroscopic YAG/dye system with intensified cameras for imaging, a three-pulse ballistic imaging system for spray breakup, and high speed cameras for time-resolved imaging.
The Chalmers team includes research engineers and technicians, faculty, researchers, and PhD students performing various kinds of experiments. Such projects are usually conducted in collaboration with an internal group who develop CFD models of the process under study (spray breakup, combustion, turbulent combustion and so forth). The lab also collaborates with other Chalmers research groups related to alternative fuels, catalysis, and advanced controls.
