Automobile | Automobile is a subclass of SelfPoweredRoadVehicles including passenger cars, family vans, light trucks, and sport utility vehicles. In general, this class covers four-wheeled passenger road vehicles. |
| AutomobileExhaustSystem | A part of an Automobile that handles the venting of Exhaust from the Engine. It typically includes an exhaust manifold, AutomobileMuffler and Tailpipe. Modern engines may also include a CatalyticConverter and exhaust recirculation hoses and controls. |
| AutomobileIgnitionSystem | The system of an Automobile that is responsible for taking power from the Battery, increasing its voltage and sending it, with the appropriate timing, to the SparkPlugs so that sparks ignite the FuelVapor in the CombustionChambers of the Engine. |
| AutoSuspensionSystem | A system, typically consisting of Springs and Shocks that couples the Wheels or Axles of a RoadVehicle to the rest of the body, and serving to dampen the effect of uneven road surfaces on the occupants or cargo. |
| BrakeSystem | A system, typically consisting of VehicleBrakes, and often a MasterCylinder, BrakeCalipers and BrakePads that serves to slow or stop a vehicle (or just reduce its downhill acceleration). |
| EngineCoolingSystem | A system designed to keep the engine cool (and therefore prevent it from seizing), that may also heat the passenger compartment as a byproduct. |
| HydraulicCylinder | A Device consisting of a HoleRegion that is the cylinder, and a Piston. Oil is forces into one part of the cylinder, moving the piston in the opposite direction, imparting force to a shaft that is part of the piston. Note that a cylinder without a piston, or a piston without a cylinder, is not considered a hydraulic cylinder. Both parts are essential to its identity. |
| TransitSystem | A TransitSystem is a system of interconnected Transitways over which some type(s) of vehicles or travellers may pass. In addition to Transitways, TransitSystems may also include TransitJunctions and TransitTerminals. Transit systems may be demarcated by where they are located (e.g., the rail system of Afghanistan), who owns or manages them (e.g., American Airlines TransitSystem of AirRoutes, or state highways managed by TexDOT), or the type of vehicles or travellers accommodated (e.g., the system of Santa Clara county bike trails. |
