GEN HELP

[NorthernRaider]

A good diesel gennie CAN if cared for have a service lifetime rated in decades, but most ( not all) petrol gennies lives are rated in hundreds of hours. A diesel cos of the torque created and simple ignition system can generate peak power at as little as 1400 to 1800 rpm, thus the oil gets an easier life and the heavy cast of the block gets a softer ride. But petrol gennies have to be revved to get decent enough torque to turn a brushless or coreless alternator and that isften 45000, to 6000 rpm and sadly petrol engines wear quicker.

At ICI we used to hae a handfull of single cyl and twin cyl lister diesels connected to pumps or alternators for mobile site maintenence, apparently they were originally cobbled together by the lads just after WW2. They got oil changes every six weeks and just went on and on and on.
