What is a differential gearbox and what do they do? And how do the individual parts actually do their job? In this lesson, students are introduced to an important engineering element in AR/VR—the differential gearbox.

As part of a lesson series created by the University for Business and Technology, this interactive 3D lesson module on EON-XR distills  a complex topic into an easily understandable visual lesson. Starting with a visual introduction of why a differential is necessary, it allows a student to easily process what’s going on underneath the skin of the car. While there are a handful of different kinds of differentials in use today, the underlying principal remains the same for mechanical differentials.

At the end of the lesson, students are able to

1. Identify the components and explain the functions and the maintenance procedures for differentials

2. Identify differential design variations.

3. Describe the principles of the  differential.

4. Understand basic service and repair of a differential.

This lesson was created as part of the EON Reality Self-Directed Learning initiative at the University for Business and Technology, allowing for deeper learning through immersion and student created content.

A four stroke engine is a very common variation of an internal combustion engine. Most modern internal combustion-powered vehicles are four strokes, powered by either gasoline or diesel fuel. During engine operation, pistons go through four events to achieve each power cycle. The definition of an event is an up or down piston motion. Upon completion of the four events, the cycle is complete and ready to begin again.

What are the four events?

1. Intake stroke: The piston moves downward to the bottom, this increases the volume to allow a fuel-air mixture to enter the chamber.
2. Compression stroke: The intake valve is closed, and the piston moves up the chamber to the top. This compresses the fuel-air mixture. At the end of this stroke, a spark plug provides the compressed fuel with the activation energy required to begin combustion.
3. Power Stroke: As the fuel reaches the end of it’s combustion, the heat released from combusting hydrocarbons increases the pressure which causes the gas to push down on the piston and create the power output.
4. Exhaust stroke: As the piston reaches the bottom, the exhaust valve opens. The remaining exhaust gas is pushed out by the piston as it moves back upwards.

In this lesson created by the University for Business and Technology, you can learn about the role that air recuperators can play in driving energy efficiencies and limiting greenhouse gas emissions.

Natural gas-fired process furnaces are widely used in industry, particularly in applications involving metallurgy, heat-treating, glass and ceramics. Even at today’s attractive rates for natural gas as an industrial fuel, it makes complete sense to recover as much of the waste heat from the furnace as possible to improve energy efficiencies. According to the U.S. Department of Energy, the recuperator is the most widely used heat recovery device.

In any furnace operation, heat is lost from the furnace skin, from heated product leaving the treatment area, from conveyer or pusher equipment, from excessive draft and from open doors or other access points. But easily the largest and most concentrated type of heat loss is from the furnace exhaust, some with temperatures of 1000° F or higher.  Fortunately, this is usually also the most practical heat to recover and reuse.

Learn about the structure and functions of the air recuperator and how you can install one in our hands on immersive lesson today.
