Arrangement for heating the intake pipe of a spark-ignited internal combustion engine

摘要

An arrangement for heating the intake pipe of a spark-ignited internal combustion engine with electrical heating elements having a positive temperature coefficient. These heating elements are located on a heating plate which forms part of the intake pipe wall, and are held by a carrier member, rigidly fastened to these elements. This carrier member has several elastic plates, one for each heating element, connected to one central current contact surface. The carrier member is centered in the heating plate and is loaded by a compression spring which is centered in the cover of the housing of the arrangement.
