Indirect Petrol Injection
Since its creation, internal combustion engines have evolved significantly due to the continuous demand for higher performance, lower consumption and, in recent times, limited production of toxic or polluting substances.
On these three aspects, the fuel supply system has a great influence, which has evolved from the carburettor to the mechanical injection systems first and to the electronic injection systems afterwards, achieving an ever greater precision in the fuel metering and new functionalities for a more efficient and coherent work.
With the implementation of additional functions and the development of integral engine control systems, the electro-hydraulic system regulates and corrects in an adaptive way not only the fuel supply, but also the air supply in order to optimise the engine response in all working conditions. At present, the injection systems manage the work of each of the engine cylinders separately to achieve the highest performance of the assembly and are to compensate for irregular wear and even for small failures.
Thus, the objective of this course covers the study and understanding of the following concepts:
- Combustion process.
- Operation of a 4-stroke engine.
- Beginnings of gasoline injection systems.
- Evolution of indirect fuel injection systems.
- Different sensors and actuators that perform the measurement and regulation functions.
- Multiple functions performed by the injection system.
- Calculation structure and work strategies of modern injection systems.
- Checks to be carried out on the components and the system itself for its repair.
