Abstract: The invention relates to a combustion engine with fuel injection system, having at least one cylinder with an air inlet passage, into which passage opens a fuel spray valve which is connected to a fuel pipe with pump. Disposed in the fuel pipe or on the spray valve is a fuel heating element with which the infed fuel can come into direct contact.

Abstract: A thermostat comprises a bimetal switch element reacting upon changes in temperatures which on one of its ends is fastened to a frame and on its other end is provided with an electric contact adapted to engage a fixed contact provided on the frame. The frame comprises two mutually parallel sheet-like metallic contact carriers forming a base unit, through which two parallel pins are extending for connection of both contact carriers and on which pins the contact carrierrs, with a tight fit, are slidable to and fro relative to one another while being held in permanent mutually parallel relation during the sliding. The parallel pins in the thermostat are formed of a ceramic material of positive temperature coefficient of resistivity which serve to electrically space the two metallic contact carriers while also serving as a self-regulating external heating means for the thermostat.

Abstract: A thermostat comprising a bimetal switch element reacting at selected temperatures which on one of its ends is fastened on a frame and on the other end is provided with an electric contact adapted to engage a fixed contact provided on the frame, said frame comprising two mutually parallel sheet-like metallic contact carriers forming a base unit, through which two parallel ceramic pins are extending for insulating connection of the two contact carriers and on which pins the contact carriers, with a tight fit, are slidable to and fro relative to one another and are maintained permanently mutually parallel during such mounting, each of said contact carriers having an aperture for lateral exposing of nearly the complete bimetal switch element.
