The calculated ignition index (CII), together with the calculated carbon aromaticity index (CCAI), are empirical indicators which describe the characteristics or properties of a fuel. [ 1 ] Both CII and CCAI are calculated from the density and kinematic viscosity of the fuel.
The calculated carbon aromaticity index (CCAI) is an index of the ignition quality of residual fuel oil. The running of all internal combustion engines is dependent on the ignition quality of the fuel. For spark-ignition engines the fuel has an octane rating.
The EF English Proficiency Index (EF EPI) attempts to rank countries by the equity of English language skills amongst those adults who took the EF test. [2] It is the product of EF Education First, an international education company, and draws its conclusions from data collected via English tests available for free over the internet.

Since the lack of volatile methylcyclohexane makes its ignition difficult, a separate priming fluid PF-1 with about 10-12% of this additive is required for the engine start-up. [5] Its main use is in the Tomahawk missiles. [6] The Russian equivalent is called detsilin .
Flammability diagram, green dotted line shows safe purging of an air-filled vessel, first with nitrogen, then with methane, to avoid the flammable region. The limiting oxygen concentration is shown in the lower right of the diagram.

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. As in other forms of combustion , this exothermic reaction produces heat that can be transformed into work in a heat engine .
