Diesel fuel preheater for vehicle engine

摘要

The preheater uses a resistance ceramic component (1) with a positive-temperature coefficient. This PTC component is arranged between contact elements (2) made of conducting material e.g. Al or Al alloy with Mg and/or Si. Each provide a contact plate (6), and, at right angles to this in the longitudinal direction, have ribs (4) arranged to obtain a large heat-exchanging area and are elastically pressed in the direction of the PTC component.
