Deutz Diesel Engines have been around since 1864 and this video is one of the best I've seen on animatiing the diesel engine 4 stroke principle. (god bless computer technology!)
The double overhead cam engineering shown in the video shows stroke by stroke what goes on in a internal combustion diesel engine. The main advantage using overhead cam technology is less moving parts, mainly... no pushrods
Mind you the timing chain and cam gears would have to be rock solid with the extra duties. When you think about it the size and length of the chain would be an advantage since there would be a larger surface in length to distribute overall wear and load.
Note the chain tensioner device on the side. I'm not sure how it monitors and adjusts the chain tension but definitely required.
Here's A Timeline on the Deutz Diesel Engine History
1864: N.A. Otto & Cie. is founded in Cologne, Germany.
1869: The company is renamed Langen, Otto & Roosen.
1872: Company is transformed into a public share company and is renamed Gasmotoren-Fabrik Deutz AG.
1921: Cooperation with Motorenfabrik Oberursel starts and name is changed to Motorenfabrik Deutz AG.
1930: Company merges with Maschinenbauanstalt Humboldt AG and Motorenfabrik Oberursel to become Humboldt-Deutzmotoren AG.
1938: The company is integrated into Peter Klöckner's conglomerate and renamed Klöckner-Humboldt-Deutz AG (KHD).
1953: KHD becomes independent again.
1992: KHD AG is transformed into a management holding company.
1997: The company is renamed Deutz AG.
Company Overview:
Deutz AG is one of Germany's leading manufacturers of diesel and gas engines for the global market. The Deutz product range includes liquid and air-cooled high-speed diesel and gas engines with a performance of four to 7.4 kilowatts (kW) which are used in cars, tractors, ships, turbines, compressors, and pumps, to name but a few. Deutz is the main supplier of diesel engines for Swedish auto maker Volvo AB.
The company's industrial plant business division is organized under the umbrella of KHD Humboldt Wedag and builds industrial plants for the cement, mining, and aluminum industry. Deutz has sales and service offices all around the world. Deutsche Bank owns a 25 percent share in Deutz, while Volvo holds a ten percent stake.
That's quite a history on a diesel engine that's been around for so long and really accentuates German technology.
