Camshaft Lubrication Tubes This tube is used for lubrication of the cams.

Fuel Return Pipes This duct is adopted for the return of non used fuel from the injectors.

Diesel Particle Filter Tubes (DPF Tubes) These ducts are connected to the particle filter to monitor pressure and congestion conditions.

Water Tubes These ducts are used for the transport of cooling liquid.

Multilayers These sleeves are used as thermal protection within the engine compartment.

Acoustic Air Intake Ducts The acoustic air intake duct has the function to transport fresh air for the engine to the filter box. Its acoustic function results from the porous characteristic of the wall section.

Oil Cooling Pipes These ducts are used to cool down the turbo charger with cooling liquid.

Oil Return Pipes These pipes are used to return used oil to the oil sump.

Oil Feed Pipes (Oil Drains) These ducts assure continuous lubrication of the axle-bearing in the turbo charger.

Turbo Outlet Ducts These ducts have the function to transport the compressed air from the turbocharger to the intercooler.

EGR coolers These heat exchangers are used for cooling the exhaust gas within the EGR circuit of combustion engines.

EGR Pipes These ducts transport a proportion of the burnt exhaust gas between the different elements (outlet manifold, EGR-cooler, EGR-valve, intake manifold) of the exhaust gas re-circulation circuit (EGR circuit).
