Yes, they put in the energy to compress the air 'offline' and then have that free to propel the vehicle. The cooling of the charge also improves the efficiency, the useful energy output is proportional to the temperature difference before and after the combustion.
A high capacity intercooler would be an interesting experiment also in utility vehicles.
Aluminium is also significantly cheaper, and easier to machine.
Titanium (or high strength steel, which is the strongest both per area and per weight and also the most expensive and difficult to machine) would be used where the volume of the part would be a concern.
The 7000 aluminium alloys are similar to titanium in strenght/weight
Anybody who is interested in it
