Stratified Charge Combustion
Stratified charge combustion places a rich mixture near the spark plug while the rest of the cylinder is lean, saving fuel at light load.
What is Stratified Charge Combustion?
It needs direct injection to place the fuel precisely. Overall, the engine runs much leaner than normal. Lean running raises NOx, so special catalysts are needed. Homogeneous mode, with an even mixture, is used at higher loads.
How it works
Fuel is injected late in the compression stroke and guided to the plug, forming a small ignitable cloud.
Why it matters for your car
Sulphur in fuel can harm NOx storage catalysts. Many modern engines use it little or not at all because of emission rules.
