Engines and the electrical system 

Lesson goals

• You can fill in the gaps in a listening exercise. 
• You can explain how a combustion engine and a piston engine work. 
• You can use prepositions in a sentence. 
• You can voice your own opinion. 

What do you know about troubleshooting?

Vocabulary practice

The following words are randomly picked for this vocabulary practice. 

Let's see whose been practicing. 

Do not use your reader for this warm-up exercise. 

What does the word frantically mean?
e.g.
"The two ladies competing for his attention waved frantically at him"

Can you name things that relate to the word: "Vulnerable"

Can you make a sentence with the word: "Collision"

Find and show a picture that has to do with the word "velocity"

Exercise 1:  Fill in the gap

Air is sucked in via the 1__________________________ The majority of the air is 2____________________ the engine as pure thrust. The rest enters the engine and is squeezed through 3__________________________ consisting of a series of 4______________________. The pressure 5_________________________ at each stage as the area’s squeezed. In the 6__________________________, the air is mixed with fuel and 7__________________________. The hotter explosion is directed towards the back of the engine, generating more 8_________________________ and 9_________________________ the turbines, which in turn are linked to the 10___________________________ and 11__________________________.

B The piston engine

Air is drawn inside 12_________________________________. Then it is compressed by 13_______________________________ and mixed with either diesel or 14__________________________. As the mixture 15___________________________, the energy created pushes the piston to the 16__________________________ of the cylinder. The piston then returns to the top in a 17____________________________ process. 18_________________________ connected to a 19_____________________________ convert the vertical movement of the cylinder to a 20________________________________ motion.

Instructions: 

Listen to the video carefully and fill in the missing word you hear in the video!

Exercise 2

Focus on English Fluency, Not Grammar

When you speak in English, how often do you stop? The more you stop, the less confident you sound and the less comfortable you become. 

Think in English

If you think in your native language and then try to speak English, you’ll always have to translate between languages. Translating isn’t an easy thing to do! Even people fluent in two or more languages have trouble switching between languages.

Exercise 2a

• Now try to explain by speaking out loud how the gas turbine works by looking at the picture below without reading the sentences above.
• Work in pairs.

Exercise 2b

• Now try to explain by speaking out loud how the gas turbine works by looking at the picture below without reading the sentences above.
  
• Work in pairs.

Exercise

• Do the listening exercise at exercise 3.

The video starts with the remark that when there is an alternator failure indication, in many cases the problem is not with the alternator.

Please fill in the table at exercise 3, by watching the video, try to tell how certain problems happen based on what you heard in the video!

Done?  Translate the words from the video at exercise 4
