描述
窜气是指从发动机燃烧室中逸出到曲轴箱的气体。 这些气体必须在进气歧管中再循环,避免对发动机造成过压损坏。 当气体到达进气歧管,气体发生膨胀,气体中的水分会结冰,从而损坏涡轮增压器。 窜气加热器可为

Blow-By Heater  
Features  
Self regulated PTC heating elements  
Wide power range available  
Choice of connectors and terminals  
Benefits  
Robust construction makes this heater well suited to  
harsh environments  
PTC self regulates the power absorption in function of  
flow and temperature of the Blow-by gases  
No external thermostat needed due to low power  
consumption  
General Description  
Applications  
Blow-by gases escape from the combustion chamber of the  
engine and reach the crankcase. These gases must be re-  
circulated in the intake manifold to avoid overpressure  
damages to the engine. When the gases reach the intake  
manifold they expand and the moisture contained within them  
can become ice, damaging the turbocharger.  
All diesel and gasoline engines  
The Blow-by Heater keeps these gases warm and prevents  
ice formation.  
Operation  
Basic Principle  
When the vehicle ECU detects the risk of ice formation, the Blow-by Heater is switched on by an external relay or power  
switch. The Blow-by Heater warms the re-circulated crankcase gases, which avoids the risk of damages to the compressor.  
Packaging Options  
Custom packaging can be provided to meet any need, please contact Littelfuse Engineering fordetails.
