INTERNAL COMBUSTION ENGINE

摘要

Internal combustion engine. A mineral oil (as defined)is vaporized in an electrically heated heat exchanger, the vaporized oil being added to each combustible charge supplied to the cylinders of a multi-cylinder internal combustion engine. The heat exchanger can be (a) a helically wound tube whose convolutions extend around the whole or a part of the length of at least one electrical heating element, or (b) at least one helically wound electrical heating element whose convolutions extend around the whole or a part of the length of a straight tube. The oil enters the tube either under the influence of gravity or from the output side of a pump. The arrangement includes a thermostat for temperature control and a cut-out for battery disconnection when the oil level reaches a predetermined minimum. The wiring is such that the engine must be running for the heating element(s) to be heated.
