Petrol Injection
Through the video lessons, you will get to know the different injection systems of petrol engines, their characteristics, specifics, elements and principle of operation.
Reasons for introducing fuel injection
Lesson
In the video, you will find out the reasons for introducing fuel injection instead of carburettors, the advantages of injection, which are the losses in engine operation, and what are torque and engine power.
Air Intake Elements
Lesson
In this lesson, you can learn about the excess air coefficient lambda and how the mixture of fuel and air is defined, what are the operating states of the engine, the elements of the air intake subsystem and how the air filter affects the operation of the injection system.
Air Intake Regulation
Lesson
Based on the signal from the throttle position sensor and other data, the engine control unit can regulate the engine speed at idle through the regulator.
Electronic Throttle Control
Lesson
Electronic throttle control (Electronic Power Control) is an electronic control system for controlling engine torque. In this video lesson, you can see what elements this system consists of and how it works.
Exhaust Gas Recirculation – EGR
Lesson
The EGR valve recirculates the exhaust gas into the intake manifold of the engine to reduce the emission of nitrogen oxide as a component harmful to health and comply with limited emissions regulations.
Dynamic Supercharging
Lesson
Dynamic chargers use some natural physical phenomena that, under certain conditions can increase cylinder charging. You can see why they are used, what they are and how they work in this video.
Turbocharger Systems
Lesson
Independent chargers use some form of external energy as a drive, which can be exhaust gas, electrical or mechanical. The most famous is the turbocharger.
Fuel Supply System
Lesson
The fuel supply system consists of several elements that together participate in the delivery of gasoline for injection. Proper and efficient operation of the engine depends on the correct amount of fuel injected to form the required mixture.
Fuel Pump
Lesson
This video shows the task, types, elements, working principle and electrical connection diagram of the fuel pump in the injection system.
