Cummins NH-220 Engine for ATS and ETS2 Many of my sources for technical details can be found in the 'docs' directory, however I also need to credit the YouTube videos from which I took sound files, as well as some web pages I found textual information on. 1. https://www.youtube.com/watch?v=TpfhFw0QopM&t=5m45s 1949 Kenworth - Pride of the Osborne Trucking Fleet This is the video that introduced me to this particular engine. I fell in love with startup and idle sounds and decided I had to have this engine in ATS and ETS2. The majority of the exterior engine sounds come from this video. 2. https://www.youtube.com/watch?v=AQoKzOyj1M0 220 Cummins backdrop manifold with straight pipe in a 1962 freightliner cabover The majority of the interior engine sounds come from this video. Finally, I borrowed the jake brake and the "no fuel" sounds from Kreichbaum's Cummins N14c. I couldn't find anything clean enough to use, and the N14 is from the same line of engines (just about 40 years later).
