Lessons

1. Engines – General Overview

Length: 6 minutesAuthor: Engineering ExplainedComplexity: Easy

How engines work. What is an internal combustion engine? This video is the perfect introduction into learning about how cars work, starting with the most important part, the engine.

How gasoline engines differ from diesel engines.

Length: 5 minutesAuthor: Engineering ExplainedComplexity: Easy

What is the difference between gasoline and diesel engines? The difference between the gasoline (Otto) cycle and the Diesel engine cycle. A look at thermodynamics and how these cycles are different. The main difference is the fuel injection stage, as this occurs after compression in Diesel engines.

Two Strokes Engine Explained

Author: Engineering ExplainedComplexity: Easy

Not all automotive engines operate with a four stroke cycle. Though two-strokes are more common in small engine applications like dirt bikes, atvs, lawnmowers, etc, they can also be found in some cars.

2. Engine Components/Features

Author: Engineering Explained

One of the most important sub-assemblies of an engine is the valvetrain, which consists of the camshafts which are used to open and close the intake and exhaust valves. There are three main types of valvetrains, as described in this video: Of course, the engine needs fuel to produce power, which is fed to the cylinders by [...]

3. Clutches and Torque Converters

Author: Engineering Explained

In order for an engine to send its rotational energy from the crankshaft to the transmission, a device must act as an intermediary, since these two devices (the engine and transmission) will be rotating at different speeds. This is accomplished primarily by a clutch in manual vehicles, and by a torque converter in automatic vehicles. [...]

4. Transmissions Explained

Author: Engineering Explained

This lesson explores the step of passing the transmitted power from the torque converter or clutch to the driveshaft, all of which occurs inside the transmission. First let's take a look at how automatic and manual transmissions work. https://youtu.be/2Ld6xhJuGBk Now that we understand how the power is transmitted, it is important to understand why different [...]

5. Drivetrain Layout

Author: Engineering Explained

The final touch of how a vehicle puts the power on the ground includes various layouts. The car may accelerate using only the front tires, only the rear tires, both simultaneously, or both under various conditions. The most common setup for small cars and sedans is front wheel drive, meaning the front two tires are [...]

6. Suspension Explained

Author: Engineering Explained

The purpose of a suspension is to ensure that all four tires (or more) are touching the groundat all times, ensuring proper friction so driving is safe, even in scenarios such as driving over potholes or uneven road surfaces. Before understanding suspensions and the various types of suspensions, it is important to understand tire alignment. There [...]

7. Brakes & Safety

Author: Engineering Explained

There are two main types of brakes used on modern production cars. These include disc brakes and drum brakes. Disc brakes are most common today due to their capability of dissipating heat, and they are self cleaning. They are more expensive typically. https://youtu.be/OjrY7G8o99U Drum brakes are cheaper, and are self energizing, meaning they can apply [...]

8. Forced Induction: Turbo and Superchargers

Author: Engineering Explained

Small displacement, lots of power. Forced induction is one of the easiest ways to greatly increase engine power. To start things off, a quick video on the purpose of forced induction. https://youtu.be/vaL6LFQHD-k Next, let's look at how a turbocharger creates boost, and the components involved that aid in the functioning of a turbocharger. https://youtu.be/zenMEj0cAC4 A [...]

9. Special Automotive Topics

Author: Engineering Explained

This is more of a smorgasbord of automotive information rather than a lesson. Nonetheless, there are important topics within, and interesting videos highlighting specific vehicles. First off, we'll start with an engineering masterpiece, the Nissan GT-R. https://youtu.be/CwQQgh5CnIE After watching a video of a vehicle which seems to defy physics and break frictional laws, let's take [...]

10. Formula 1 Engineering Explained

Author: Engineering Explained

Formula 1 is the highest level of automotive racing. It leads the industry in technology, speed, and innovation. In this lesson I will break down the common features of a Formula 1 vehicle, and explain just how these vehicles work. This lesson includes some videos which have been in previous videos, however the videos are [...]
