1. MP03: Heat engine and auxiliary systems (GS Automoció)
UF1: Car’s engine: operation, components and checks
NA1: Car’s engine: components
The most important system in a car is the engine. It allows the vehicle to move.
Nowadays, We have different engines, depending on the energy source that can move,
eg. Fuel engine, diesel engine, electrical engine, hydrogen engine,… Now, we will learn
different parts and pieces of the most common engine, de fuel one. However, other
engines are similar, with some modifications
Activity 1.- Warming-up (Speaking)
Discuss about the following questions:
- What pieces or components do you know in a car’s engine?
- Do you know some functions that make an engine?

2. Context: Here you can see different engine's components and their situation on the
engine

3. Activity 2.- In pairs, ask your partner about the place of 10 components in the engine of
the picture. Eg:
-
Where is located the distributor?
The distributor is located on the water pump, or, the distributor is located to the
right of the alternator
Activity 3.- Now, we learn the function of the components. Match the components of
the engine with the definition of its function

Activity 4.- Take all these cards with the names and the functions of the 24
components and, in groups of 3, go to the garage. Choose one engine and tag their
pieces with its name and its function
