2. Stratified charge engine - Wikipedia

   en.wikipedia.org/wiki/Stratified_charge_engine

   This produces a homogeneous charge: a homogeneous mixture of air and fuel, which is ignited by a spark plug at a predetermined moment near the top of the compression stroke. In a homogeneous charge system, the air/fuel ratio is kept very close to stoichiometric , meaning it contains the exact amount of air necessary for complete combustion of ...

3. Homogeneous charge compression ignition - Wikipedia

   en.wikipedia.org/wiki/Homogeneous_charge...

   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 .

4. Gasoline direct injection - Wikipedia

   en.wikipedia.org/wiki/Gasoline_direct_injection

   Stratified charge mode also keeps the flame away from the cylinder walls, reducing the thermal losses. [12] Since mixtures too lean cannot be ignited with a spark-plug (due to a lack of fuel), the charge needs to be stratified (e. g. a small zone of fuel/air mixture around the spark plug needs to be created). [13]

5. Lean-burn - Wikipedia

   en.wikipedia.org/wiki/Lean-burn

   The newer Honda stratified charge (lean-burn engines) operate on air–fuel ratios as high as 22:1. The amount of fuel drawn into the engine is much lower than a typical gasoline engine, which operates at 14.7:1—the chemical stoichiometric ideal for complete combustion when averaging gasoline to the petrochemical industries' accepted standard ...
