Hi Henri and Colleagues, Henri, you advise us of the engine details, but what is to be your application?
My installation plans to turbo charge a 350 chev engine c/w positive displacement pump for the gasifier It would appear from making such an effort, that you do seek performance, and I can offer a few comments that might be of interest for further development if you have the capability. In April 2004, my associates of that time in Winnipeg were rebuilding Chev 502 "Crate Engines" to maximize their design for producer gas. One of the team specialized in tuning these engines for racing purposes, and he was set up with all new Dyno equipment for the project. Apart from all the polishing of ports, new pistons, etc, the emphasis was on the cam shafts, and these were re-made and tested intensively making them the most expensive cam shafts in N.America, according to the guy who was paying the bills! There were six of these engines built, and before anyone asks, I have no idea where they went to, due to the security breach and loss of integrity to the whole project. I did however see them working up on the dyno, and all I can say is that I have never seen so much grunt come out of an engine on producer gas before at 3,200 RPM. As interesting as this may be, all the other issues of exhaust emissions,etc, were not addressed, but only one factor made it possible to really allow this type of test. Engines can perform outstandingly on producer gas, if purpose built. The engine performance though, can only be attained if the gas making process can meet the engine demand for gas without changing it's basic standard gas analysis. In the Winnipeg project, the Mk2 Mega Class gasifier was able to make enough gas to supply nine of these engines flat out, so testing one at a time placed no stress on the gas supply. >From a practical perspective which applies to most of us working with producer >gas, we are surrounded with perfectly good engines that run well for most >applications on producer gas. We as individuals with specialist capability, >can modify and rebuild any of these engines that push normal performance >boundaries, just the same as for liquid fuels.
