OBD II systems use several modes of operation. List three of them.

Expert Solution & Answer
Check Mark
To determine

OBD 2 system and modes of operation.

Explanation of Solution

The OBD system is an On-Board Diagnosis system. It can be installed in all cars and some light duty trucks. It helps in controlling the engine parts and it has proved its importance by keeping an eye on the other parts of a vehicle also. For example, chassis, accessories and other components of cars.

It helps in a vehicle’s maintenance and diagnoses the parts of a vehicle. It helps in producing less emission thus protecting the environment from harmful emission caused by a vehicle’s emission. The diagnosis or maintenance engine light is present at the dashboard. With these light signals, we can check the service needed and the problems caused to a vehicle. It is used for an overall scanning of the vehicle. If there is any problem in the vehicle, the light indicator will indicate so. It provides a list of codes which helps in running on-board diagnosis.

These diagnoses are carried out by collecting the information from the vehicle. This information is analyzed to come up with a suitable solution.

Modes of operation of this system are listed below:

  1. Live date track
  2. Freeze frames
  3. Diagnosis trouble codes.

The wall of a furnace has a thickness of 5 cm and thermal conductivity of 0.7 W/m-°C. The inside surface is heated by convection with a hot gas at 402°C and a heat transfer coefficient of 37 W/m²-°C. The outside surface has an emissivity of 0.8 and is exposed to air at 27°C with a heat transfer coefficient of 20 W/m²-ºC. Assume that the furnace is inside a large room with walls, floor and ceiling at 27°C. Show the thermal circuit and determine the heat flux through the furnace wall. h₁ T₁ k -L T. sur ho E
