Internal combustion engines
The internal combustion engine laboratory presently includes:
A) A sound-proof test cell equipped with eddy current dynamometer, real time measurement instrumentation and flue gas conditioning. A new programmable system able to control both the engine and the dynamometer has been recently set up.
B) A gas emission measuring system for the analysis of exhaust gas composition. The instrumentation allows to record the concentration of total hydrocarbons (THC), nitric oxides (NO and NO2), carbon monoxide and dioxide, and oxygen at engine exhaust.
C) Two test benches without thermal and acoustic insulation equipped with Froude hydraulic brake dynamometers.
D) Three spark-ignition (SI) commercial engines (a 4-cylinders 1200cc car engine and two motorbike engines).
E) Discharge-flow test rig for the measurement of valve discharge flow coefficient.
