Pros and Cons of Control systems

[Aaragorn]

I want to know about the control systems for cng. I have a basic understanding that there are two types.

1- Sequential Injection
2- Aspiration

I also hear that control systems for LPG and CNG are basically the same.

So what is the truth and what are the misconceptions here?

What are the pros and cons of each control system?

Fuel Injection - Pro: Good performance and emission compliance
Con: Cost and complexity to set up (calibration, etc)

Aspirator / Mixer - Pro: Cost
Con: Poor Performance and emissions
