Syngas in Internal Combustion Engines

Syngas in Internal Combustion Engines 

automobiles, tractors, generators

Lets go through the basic operation of a gasification system for an internal combustion engine. Syngas can be created by any gasifier of your choice; for a passenger vehicle, one would typically use an imbert style gasifier.

In a normal imbert gasifier, the fuel is loaded into a bunker section which may feed the fuel by gravity or, alternatively, deliver it to the gasifier with a feed system (such as an auger). The gas exiting the gasifier may immediately enter a cyclone filter. This a very effective way to eliminate large particulates. Gas cooling removes moisture from the gas by condensation, and gas temperatures below 100 degrees Fahrenheit are important for adequate engine performance. Also, cooler gases mix more readily with outside air which is important when you need to adjust the fuel-air mixture.

Gas filtering is vital to protect your engine. Some filters clean hot gas, while others clean the gas after it has cooled. There can be single or multiple stages but when it comes to gas filtering, cost and simplicity are very important. Some common filters use hay or wood chips as the filter material. The syngas is usually pulled out of the gasifier and through the system by the engine's own vacuum. This vacuum provides the negative pressure for the gasifier's inlet air.

Before the syngas line reaches the engine, it is mixed with outside air to obtain the correct fuel air ratio. Typically, the optimal ratio is about 50:50. This mixture is closely regulated by the operator to maintain an ideal ratio of combustible gasses to outside air, as a mixture too rich or too lean will in either case stall the engine. Some of the more modern systems adjust the fuel air mixture automatically with a control system, typically using an oxygen sensor. After it is mixed, the gas/air combination enters the engine and is ignited by the spark plugs just as gasoline vapors would be. Usually the ignition timing of the engine is advanced to take advantage of the higher octane fuel. Engines running on syngas have a reduced power output compared to gasoline by about 30-50%. This reduced power can be avoided and power can even be gained through the used of forced induction methods like turbocharging and supercharging.

Site Map

By putting all of your content into nested categories you can give users and search engines access to everything using a menu.


  • Joomla!
    • Extensions

      The Joomla! content management system lets you create webpages of various types using extensions. There are 5 basic types of extensions: components, modules, templates, languages, and plugins. Your website includes the extensions you need to create a basic website in English, but thousands of additional extensions of all types are available. The Joomla! Extensions Directory is the largest directory of Joomla! extensions.

      • Components

        Component ImageComponents are larger extensions that produce the major content for your site. Each component has one or more "views" that control how content is displayed.In the Joomla! administrator there are additional extensions such as Menus, Redirection, and the extension managers.

      • Modules

        Media ImageModules are small blocks of content that can be displayed in positions on a web page. The menus on this site are displayed in modules. The core of Joomla! includes 17 separate modules ranging from login to search to random images. Each module has a name that starts mod_ but when it displays it has a title. In the descriptions in this section, the titles are the same as the names.

        • Content Modules

          Content modules display article and other information from the content component.

        • User Modules

          User modules interact with the user system, allowing users to login, showing who is logged in, and showing the most recently registered users.

        • Display Modules

          These modules display information from components other than content and user. These include weblinks, news feeds and the media manager.

        • Utility Modules

          Utility modules provide useful functionality such as search, syndication, and statistics.

        • Navigation Modules

          Navigation modules help your visitors move through your site and find what they need.

          Menus provide your site with structure and help your visitors navigate your site.  Although they are all based on the same menu module, the variety of ways menus are used in the sample data show how flexible this module is.

          A menu can range from extremely simple (for example the top menu or the menu for the Australian Parks sample site) to extremely complex (for example the About Joomla! menu with its many levels). They can also be used for other types of presentation such as the site map linked from the "This Site" menu.

          Breadcrumbs provide users with information about where they are in a site.

      • Templates

        Media ImageTemplates give your site its look and feel. They determine layout, colors, type faces, graphics and other aspects of design that make your site unique. Your installation of Joomla comes prepackaged with three front end templates and two backend templates. Help

      • Plugins

        Plugin ImagePlugins are small task oriented extensions that enhance the Joomla! framework. Some are associated with particular extensions and others, such as editors, are used across all of Joomla!. Most beginning users do not need to change any of the plugins that install with Joomla!. Help

  • Park Site
    • Park Blog

      Here is where I will blog all about the parks of Australia.

      You can make a blog on your website by creating a category to write you blog posts in (this one is called Park Blog). Each blog post will be an article in that category. If you make a category blog menu link with 1 column it will look like this page, if you display the category description (this part) displayed.

      To enhance your blog you may want to add  extensions for comments, interacting with social network sites, tagging, and keeping in contact with your readers.   You will also enable the syndication that is included in Joomla! (in the Integration Options set Show Feed Link to Show an make sure to display the syndication module on the page).

    • Photo Gallery

      These are my photos from parks I have visited (I didn't take them, they are all from Wikimedia Commons).

      This shows you how to make a simple image gallery using articles in com_content.

      In each article put a thumbnail image before a "readmore" and the full size image after it. Set the article to Show Intro Text: Hide.

  • Fruit Shop Site
    • Growers

      We search the whole countryside for the best fruit growers.

      You can let each supplier have a page that he or she can edit. To see this in action you will need to create a users who is in the suppliers group.  
      Create one page in the growers category for that user and make that supplier the author of the page.  That user will be able to edit his or her page.

      This illustrates the use of the Edit Own permission.
