Diesel motor air intake, with a heater, has a control to switch on the heater under idling and low loading conditions and when the particle filter is regenerated

摘要

#CMT# #/CMT# The diesel motor has a heater to heat the air drawn in through the air intake. The heater is switched on during idling (22), on starting, on a stoppage, during regeneration of a particle filter and when the motor torque (39) and speed (40) are below minimum threshold values. The heater is a heated flange. #CMT#USE : #/CMT# The system is for heating air drawn through the air intake to a diesel motor. #CMT#ADVANTAGE : #/CMT# The operation gives the diesel motor an efficient performance when idling and when under a low loading. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawings show a block diagram of the heater control function block and the time sequence of heater switching. 1 : function block 2 : characteristic field 3 : characteristic curve 22 : idling 39 : motor torque 40 : motor speed.
