I have heard of problems with SVO on Lucas pump, but not biodiesel. The viscosity of the biodiesel should be fairly close to petrodiesel, thats the whole point of making it of course, so this is quite a sensitive pump (or management computer).
1) Is your biodiesel home brew? If so, have you re-processed it to check that you've had an almost complete conversion and that therefore viscosity is as close to petrodiesel as possible? 2) Have you tried preheating the biodiesel, even a simple glycol coolant heat exchanger might elevate the temp. of the biodiesel and reduce its viscosity Even something as simple as a fuel line of copper wound around a section of upper rad hose ,and insulated, might do it. Perhaps the Peugeot already has a fuel preheater, but even so, it might be worth trying another just to thin the bio out a bit, after you have confirmed that it is bio from a virtually complete conversion. 3) Run a blend is always an option. B20, or B50. --- Ed B. www.biofuels.ca ----- Original Message ----- From: "Stephen Gerry" <[EMAIL PROTECTED]> To: <biofuel@yahoogroups.com> Sent: Friday, August 17, 2001 8:22 AM Subject: [biofuel] Lucas diesel pumps > My colleague is running a 1997 Peugeot 406 and the pump appears to be intolerant of Bio. It would appear that if you run with 100% Bio then the viscosity is higher and the rotary control (managed by the engine management system) situated within the diesel pump couldn't compensate. This leads to the engine running poorly at tick over and can cut out. This problem may be limited to only a few pumps say the Lucas technical people as pumps found in the Ford Transit have rotary controls and management systems that can cope with a wider viscosity range and they recalibrate themselves "on the fly" > > Lucas say that the only way to prove this is by removing the pump and running tests on this particular unit which will prove very expensive.
