New Freightliner Argosy

have you seen new actros have adjustable front grille vents


for better cooling of engine during summer

better heating during cold weather and also euro 6 engine try to raise engine temp as fastest as possible to get better emision ....thats why we see some solution with exhaust brake during heatings

also for better aerodynamics ....

 

Volvo trucks got this system in 90-s with D12A. When you release park brake, exaust flap opens

 

If and when I move to Canada I know what truck to buy.

 

They still have it. Scania had it already in the 80s, maybe even earlier.

 

Adjustiable grille openings was called shutterstats, back from 40 s to early 80 s. So not new!

 

Yep, I remember old GAZ-51 and MAZ-200... this system had manual control and it was easy to forget to open it and overheat engine.

It is funny but shutterstats were used on some classical cars.

Imo, with air solenoid control shutterstats may be good thing

 

Ones I worked on were auto (mid 70 s) . Started out as a vtt675 903 cummins. Then pull att with it. . Ran one temp gauge per side. A lot of confused mustang owers in town!

 

Your not referring to this truck as the Argosy your driving are you?

 

looks better in blue but still ugly
