II. Diesel Engines:
The first step in designing a component for an exhaust system is to collect information on the engine it will be attached to. The engine produces all emissions that will pass through our measurement system so it is crucial that we know exactly what these engines can do. Being that Cummins is a large engine producer and is responsible for multiple classes of engines in uses that range “from emergency vehicles to 18-wheelers, berry pickers to 360-ton mining haul trucks”, we have to choose a particular focus to avoid overextending ourselves. Our group has chosen to focus on the Cummins engines that belong to their “On-Highway” class. This class is broken down further into Medium Duty Trucks, Heavy Duty Trucks, Dodge Ram, Motor Homes, School Buses, Urban Buses and Shuttles, as well Fire and Emergency vehicles. The Cummins engines that service these vehicles are listed as follows:
· Cummins ISB (picture on right): 185 – 275 hp · Medium Duty Trucks · Motor Home · School Bus · Urban Bus & Shuttle · Fire & Emergency · Cummins ISC: 260 – 315 hp · Medium Duty Trucks · Motor Home · School Bus · Urban Bus & Shuttle · Fire & Emergency
