or surface ignition or hot-bulb. What we call em is not germane to the question I've been pondering.
Why were so many of this type of engine made around the Baltic and why were they also popular in Russia and Poland?
The generally offered explanation revolves around a perceived suitability for powering Baltic fishing boats. This may be so but I offer the following alternative:
- the most readily available fuel would surely have been Light Russian Crude (akin to diesel and sold as inter alia Russolene) which was presumably exported, initially in barrels, through Russia's all-year ports on the Baltic.
-but early full diesels were constructed on a scale unsuitable for smallish fishing vessels. Thus the compromise of 2T semi-diesel? Further East the Rumanian oil-fields began early and more readily produced a lighter fuel akin to paraffin and here the spark ignition paraffin engine seems to have dominated. Your thoughts??
