As a government entity, obviously your department won't want to invalidate the warranty and violate federal law by just deleting the emission equipment. The new diesel emission standards have been a huge pain for the emergency vehicle world. The vehicles don't get driven long and far enough to passively regen and clean the DPF. Our two new engines and ladder truck have to do an active regen as often as every four days, which entails parking the truck and running it at a very high idle for 20-40 minutes. Failure to do this causes trouble codes and eventually it can cause an engine shutdown. Because of this, there has been a push to get the EPA to issue an exemption of sorts for emergency vehicle operators so that their vehicles will not shut down if they don't get regenned. This has made us think twice about getting diesel ambulances again, but our station infrastructure is set up for only pumping diesel, so we will have to endure the headaches of modern diesel emission controls for the forseeable future.
Exactly, emergency response needs to be dependable. I would delete.
