Done - finally!
posted on June 1st, 2012

I can’t believe it. I've finally finished the last work on my book – proofreading the index layout! Yayayay!! Years ago, I remember Aisha Tyler telling me that writing a book was like a homework assignment that never ends. Somehow I just finished never-ending-homework-assignment #4, and it feels really, really good. And getting emails like this makes all the long hours worthwhile:

"I just wanted to let you know that your books have strongly impacted my life. I started struggling in math in pre-algebra in 7th grade and was about to have to take algebra readiness for 8th but my parents said that if I read Kiss My Math over that summer then they would recommend me for algebra. Of course I did and made it into algebra extremely confident, having learned so much from just your book. Unfortunately, I didn’t have a very good teacher for algebra and struggled even more, so I read Hot X: Algebra Exposed. I can’t even explain how many ‘light bulbs’ went off in my head after reading that book. So much stuff that wasn’t even taught to me in class just made perfect sense in your words. The way you just ‘clicks’. I am so confident in myself now - thanks to you. Even with the things you write that aren’t about math...they just make me feel like a better person. You are my number one role model and I would not be where I am now in math without you. You’ve helped me so much. Thank you Danica! You rock! I can’t wait until your geometry book comes out!"


Oh Lucy, and all “my” girls reading my books - if I can help to make learning more fun and productive, instilling a sense of self-confidence and pride in tackling challenges - whether they be something like writing a math book or even dealing with something difficult in your personal life - then I’m a happy gal. xoxo

The common rail system prototype was developed in the late 1960s by Robert Huber of Switzerland and the technology further developed by Dr. Marco Ganser at the Swiss Federal Institute of Technology in Zurich, later of Ganser-Hydromag AG (est.1995) in Ober?geri.
The first successful usage in a production vehicle began in Japan by the mid-1990s. Dr. Shohei Itoh and Masahiko Miyaki of the Denso Corporation, a Japanese automotive parts manufacturer, developed the Common Rail fuel system for heavy duty vehicles and turned it into practical use on their ECD-U2 common-rail system mounted on the Hino Rising Ranger truck and sold for general use in 1995.[3] Denso claims the first commercial high pressure common rail system in 1995.[4]
Modern common rail systems, whilst working on the same principle sensor are governed by an engine control unit (ECU) which opens each injector electronically rather than mechanically. This was extensively prototyped in the 1990s with collaboration between Magneti Marelli,Centro Ricerche Fiat and Elasis. After research and development by the Fiat Group, the design was acquired by the German companyRobert Bosch GmbH for completion of development and refinement for mass-production Common Rail Nozzle . In hindsight, the sale appeared to be a tactical error for Fiat, as the new technology proved to be highly profitable. The Common Rail Injector Valve had little choice but to sell, however, as it was in a poor financial state at the time and lacked the resources to complete development on its own.[5] In 1997 they extended its use for passenger cars Common Rail Injector . The first passenger car that used the common rail system was the 1997 model Alfa Romeo 156 2.4 JTD,[6] and later on that same year Mercedes-Benz C 220 CDI.Common Rail Shim & Gasket kit have been used in marine and locomotive applications for some time. The Cooper-Bessemer GN-8 (circa 1942) is an example of a hydraulically operated common rail diesel engine, also known as a modified common rail.
