The rapid compression machine designed and constructed at Warsaw University of Technology creates high pressure and temperature at the end of compression stroke, leading to mixture autoignition with the possibility of the process visualization. The unique feature of the machine is the possibility ofstudyingignitionand combustion processessimilar to those existing in the engines with gas fuel injecteddirectlyto combustion chamber. The adequate characteristics of piston movement is achieved by conventional crank mechanism, however the required acceleration is introduced by the combustion of fuel-oxygen mixture under the piston. Calculationsand preliminary tests have shownthat the method is capable to achieve piston accelerations equivalentto engine rotational speedof 5000 rpm. The test chamber is equipped with pressure transducer that together with electronic piston movement transducer enables for registration of pressure profile with respect to crack angle. The light signal from the flame in the chamber is transmitted by the light pipe to phototransistor. All signals are collected by computerdata acquisition system. The preliminary study of autoignition of hydrogen-oxygen mixture was performed with the use ofthis apparatus and the results are discussed.
