Abstract
Opposed piston two-stroke engine, due to its characteristics of fast expansion, high power density and indicate efficiency, and dynamic balancing, attracts many researchers’ attention. In order to explore its combustion performance, a novel test platform consisting of a drive system and combustion control system is proposed in this paper. The drive system mainly contains a 75-kW induction motor, a synchronous gearbox, and two crankshaft mechanisms. The displacement of the piston and chamber pressure is acquired and used to control combustion parameters. Using this mechanical device, the rotary motion can be converted to the opposite movement of the two pistons precisely. All the designed functions of the platform are verified by the combustion experiments of an opposed-piston two-stroke prototype. Furthermore, the experimental data is used to verify a one-dimension simulation model to evaluate the combustion characteristics of the prototype.
