cylinder head with a verdampfungselement in a luftansaugkanal

摘要

A cylinder head of an internal-combustion enbgine with at least one inlet valve and a fuel injection in an air-intake channel has an evaporation element intended for improving the fuel/air mixture formation projecting into the air-intake channel. The evaporation element has high thermal conductivity in a partition wall between the inlet-valve channels in multi-valve engines and makes direct thermal contact between the air-intake channel and the main combustion space. The heating of the mixture mass located in the air-intake channel is thus self-regulated by the combustion heat in the main combustion space. The installation avoids the hitherto necessary resistance heating constituting a drain on the power supply and improves the heating regulation of the mixture mass.
