PART: 1 As "Petroleum" was "found" about ~150 years ago, one of the first uses was to distil "lamp kerosene" for lighting. ~100 years ago they started to distil "motor kerosene", a distil fraction about 110 - 130ˇ Celsius. This was before the Diesel motor had spread into larger acceptance around the world. (And the patents of Rudolf Diesel and MAN had "run out"). Lamp kerosene is a few fractions higher, and does not include but very little aromatic components, to be able to use it indoors. Motor kerosene, on the other hand includes far more aromatics and light volatiles, which can be recognised by its "sweet-sour" smell, when burned in an Otto motor. Until the '50ies, motor kerosene had its natural low "octane" value, and did not allow higher compression ratios than ~5:1. Compare Fordson tractors' 4,5:1 as well as boat motors. "Modern" motor kerosene was "beefed up" with "lead" (MBTE?), and allowed a compression ratio of ~7,5 : 1. One cannot start an Otto motor on motor kerosene, unless the motor is at least 60ˇ Celsius. A cold motor has to be run warm on gasoline (petrol), before turning to kerosene. Motor kerosene has NOTHING to do with ANY grade of DIESEL FUELS ! (The nearest comparison would be aeronautic kerosene !) Despite this, some taxi drivers used to mix ~15-25% motor kerosene in their diesel fuel in the winter back in the '50ies and '60ies, before the WINTER GRADES where developed. But this was just an attempt to handle the PARAFFIN FALLOUTS, which stopped the fuel flow by clogging the lines and filters! The winter grades are deprived of sublimating paraffin, so the clogging is not a problem any more, to about -35ˇCelsius, (POLAR GRADE goes still further). Now, about car use: In Finland it was allowed, for a brief period, between ~February and 30.6.1982, for a private person to re-register gasoline driven cars to be driven on motor kerosene (paraffin). At that time, two car factories did market motor kerosene driven cars in Finland. (Saab and Talbot). The "monopolistic" law protecting these factories, was "turned over" in the beginning of the year 1982, but the parliament re-wrote the law again in May, coming in force from 1.7.1982. Both these commercial car models for kerosene, had their intake air pre-heated by a motor coolant heating element (heating battery, like the heating element for the passenger cabin). The kerosene was also pre-heated by a small heat exchanger from the hot motor coolant. These cars had a compression ratio of ~7,5:1. This had the consequence, that the intake-air could never come over ~80ˇ Celsius! That in turn, led to inadequate nebulisation and "gasification" by the carburettor. Behind them the exhaust was usually light bluish, with the typical smell. NEXT PART: My own solutions.
