homogeneous charge compression ignition

Another strategy attractive to both gas and diesel engineers is called homogeneous charge compression ignition, or H.C.C.I.

The free-piston engine is further well suited for homogeneous charge compression ignition (HCCI) operation.

HCCI (Homogeneous Charge Compression Ignition) combustion results in virtually no emissions and superior fuel efficiency.

Homogeneous charge compression ignition (HCCI) is a form of internal combustion in which well-mixed fuel and oxidizer (typically air) are compressed to the point of auto-ignition.

One operating cycle for engines under wide study in the industry, known as Homogeneous Charge Compression Ignition, cherry-picks the best traits from gasoline and diesel designs - low emissions and high efficiency, respectively.

Research into future alternative forms of power include the development of fuel cells, Homogeneous Charge Compression Ignition (HCCI), Stirling engines, and even using the stored energy of compressed air or liquid nitrogen.

Diesel Ignition Process Diesel engines and HCCI (Homogeneous charge compression ignition) engines, rely solely on heat and pressure created by the engine in its compression process for ignition.

Ford's HyTrans Project has developed a system which starts the ignition in 400 ms, saving a significant amount of fuel on city routes, and there are other methods to achieve even more efficient combustion, such as homogeneous charge compression ignition, being studied.

At Tech Show Torino 2008, GM Powertrain Europe announced the ignition-less HCCI (Homogeneous Charge Compression Ignition) mode of the direct injection version of 1.4 L VVT turbocharged engine.
