Benefits & Issues of Direct injection vs Port Injection [Pros & Cons]
We look at the pros and cons of direct injection vs standard fuel injection and discuss the carbon build up issue and how manufacturers are dealing with this problem.
Let's look at fuel injection and compare the modern method of direct injection vs the older tried and tested port fuel injection.
What is direct injection? How does Direct injection work?
The common problem with most modern direct injection systems is carbon build up on the intake ports. Without fuel spraying on the valves the carbon will just build up and cause problems with air flow and can potentially cause hot spots or break off in chunks and cause problems inside the engine.
Diesel and gasoline additives and if these can prevent or remove carbon build up.
Direct injection vs port injection which is better? Why
Why do manufacturers start using direct injection. TFSI DSI FSI explained and the benefits they have over fuel injectors and some of the problems you get with direct cylinder fuel injection systems.
