Analysis of Cycle-to-cycle Variations in Large Diesel and Dual Fuel Engines Based on an Instrumented Fuel Injection System

Analysis of Cycle-to-cycle Variations in Large Diesel and Dual Fuel Engines Based on an Instrumented Fuel Injection System

  • Target:

Diesel fuel injectors play a central role in the performance and robustness of large diesel and dual fuel engines. Instrumentation of such injectors has the potential to reveal detailed insights into the fuel injection process and related combustion phenomena inside the engine.

The target of this thesis is to obtain a detailed understanding of correlations between cycle-to-cycle variations in the fuel injection process and cycle-to-cycle variations in the corresponding combustion process. Recent tests on a medium-speed single-cylinder research engine at the Large Engines Competence Center (LEC) serve as a measurement database for analysis. The tests were run in both diesel and dual fuel operation and involved a specially instrumented prototype fuel injector.

  • Tasks:
  • Familiarization with engine and injection technology and corresponding measurement
    technology and measurement parameters
  • Preprocessing of engine and injection system measurement data
  • Investigation of the interrelationship between the injection system and combustion process cycle-to-cycle variations in both diesel and dual fuel operation through explorative data analysis
  • Composition of the master’s thesis
  • Prerequisites: Programming skills in Python and/or R; experience in data analysis
  • Earliest possible start date: Immediately
  • Duration: Approximately 6 months
