 Homogeneous charge compression ignition

Homogeneous Charge Compression Ignition (HCCI) is an advanced combustion technology used in internal combustion engines that combines the principles of both gasoline and diesel engines. The key features of HCCI include: 1. **Homogeneous Mixture**: In HCCI engines, a well-mixed charge of fuel and air is introduced into the combustion chamber. This is different from traditional diesel engines that inject fuel into a compressed air charge.
