Single-cylinder research engine for testing of unconventional combustion
Original language description
A base design of the scavenged pre-chamber has been finalized. The SI base variant of a single cylinder research engine was commissioned. All sensors and actuators were wired to the Engine Control Unit (ECU). Initial parameterization of the control algorithm was then performed. The research test procedures and outputs are fully compatible with the routines at the industrial partner. Base SI engine mapping was performed (petrol BA95). Two passive pre-chambers (P-C) were manufactured. A stainless steel one, able to withstand high thermal load. The second one was made of copper alloy (CuCr1Zr) with high thermal conductivity. Passive P-C with integrated temperature sensor was implemented in the original SI cylinder head and P-C engine mapping was carried out with petrol. Lean operation limits at low and high loads were mapped experimentally. CTU designed and manufactured new active pre-chamber. Škoda Auto designed, manufactured and assembled the completely new cylinder head for the active P-C. Activities closely related to 1-WP03-001.

Technical parameters
Bore / Stroke 1cyl x f74.5 / 84.9 mm, Compression ratio 11.6:1 – adjustable Maximum engine speed 6000 min-1, Maximum cylinder pressure 100 bar. Gradual improvement in environmental parameters will be controlled by accessibility of the carbonless fuel. The technical description is available under direct access to ISTA or via X Wiki at CTU in Prague as OntoDASY II at http://147.32.168.15:8080. X Wiki based OntoDASY II is better structured and contains all public opened enclosures. Ask access rights at Jan.Macek@fs.cvut.cz.
Economical parameters
Optimization of the functional sample will be realized in the near future. New multicylinder functional sample has to be designed, built and tested and implemented to the vehicle. Based on the vehicle test results the industial partner will decide the implementation in a serial production andapplication market. The university will exploit the results in the further research and education activities.
