Dieselveg - ATG Veg Kit Demo Rig

11/12/05

We now have a Demonstration Rig set up in our Workshop to show visiting customers how the ATG 2 tank system works. The kit rules are simple - start from cold on Diesel - once engine is up to normal temperature (or above 70degC) switch to Vegetable Oil - run as normal - when vehicle is to be parked up switch back to Diesel approx 2 minutes before stopping engine, the engine is then ready to start from cold on Diesel. Feedback has been very positive and most people say it shows the operation even better than the test engine. We use coloured water for a very effective, safe display. You can see at the top we have used a real injection pump and injectors and used transparent tubing on the "high pressure" lines so you can see the flow, of course these are normally solid steel lines. To the right the blue main vegetable oil filter constitutes the existing vehicle filter, apart from the tanks and ignition switch the rest of the components are supplied with the kit (for kit reference see P120801 12v 8mm with WT01 heat exchanger)

Demo Rig photo left showing Diesel mode (red), photo right showing when on Vegetable Oil (green). We simulate engine running by switching ignition on and an electrical pump starts, we have a "throttle" control valve at the rear to simulate engine consumption, we collect this in a hidden separate tank so we can speed up the demonstration, switchover to Vegetable Oil results in a visible gradual mix of colours until all green - Vegetable Oil is visible, If ignition is switched off whilst still switched to Vegetable Oil then the warning buzzer sounds for 2 seconds, switching back to diesel operates quick purge timer and there is a very fast transition back to red - Diesel.

Here's a couple of photos indicating the construction, planning makes perfect!

Test rig marked up and ready for component installation, parts fitting in progress

Even more impressive in the flesh, come and see for yourself.
