Non Conventional Engine

Introduction :

We have usually know details of conventional engines like spark ignition engine (SI) and compression ignition engine (CI). 
In SI engine uses carburetion and CI engine uses mechanical injection.but for last few years lots of research carried out to improve engine performance. because of this reason and lots of effort non-conventional engine has been developed.

Non conventional engine list following below :

1. Common Rail Direct Injection (CRDI) engine 

2. Dual fuel and multi-fuel engine

3. Free piston engine

4. Gasoline Direct Injection (GDI) engine

5. Homogeneous Charge Compression Ignition (HCCI) engine

6. Lean burn engine

7. Stirling engine 

8. Startified charge engine

9. Variable Compression Ratio (VCR) engine

10. Wankel engine
