We have now managed to establish a diesel saving of around 50% which is still quite a lot shy of the predicted 80%. In order to improve this further we have begun increasing the diameter of the pipe from the tank to the engine. Currently the pipe diameter is fairly narrow and I think the flow is being choked which limits the mass flow rate of the gas to the engine. We have tried applying pressure to the gas which does improve the mass flow rate and reduces the consumption rate however this is still limited by the narrow pipe (think of sucking a drink through a very thin straw). We have begun to install a larger pipe to the tank which will hope fully yield some good results in the coming week. Testing is getting a bit frustrating as well as we have to wait 2-3 days before there is enough high quality gas to use enough for one hours worth of testing!

We spent last weekend visiting a hill station called Mahableshwar about 130km away. Was nice to get a change of scenery although it was very cloudy and he views were mainly white outs! Visited Pune on Sunday and indulged in buying some cheap Levis and even sampled the delights of McDonalds! Also had a tour around placed called the Osho Ashram which is marketed as a plush meditation centre but is rumoured to be one big (and expensive) orgy! Mandatory HIV test on entry! Spent this weekend in Phaltan as we worked Saturday but we’re planning to visit some impressive caves next weekend near a city called Aurangabad in the North of the state.
