What is the technical support SPCCI technology?

1

What is?

using a small ignition spark plug, a combustion chamber formed in an upper air piston, the piston moves upward while pressing the unburned air-fuel mixture compressed combustion.

You know what?

Use of this technology can achieve the lean burn engine, fuel consumption can be effectively reduced.

* In order to ensure a more uniform air and fuel mixture, the fuel injection pressure will be higher.

· majority conditions still to ignition by a spark plug, to avoid the problem of convergence switching ignition mode, the engine is also easier to handle the vibration, noise.

* All the spark plug is not directly ignited gas mixture, but part of the mixed gas ignited to create a compression-ignition conditions. The spark plug in the art so that further control action.

* In order to ensure smooth operation of the high load region, the engine requires a large amount of air intake, with a highly sensitive art air supply device, the cylinder can be compressed in the height provide gas. When

Principle

engines SPCCI technical work first use a spark plug pointThe air-fuel mixture within a small range, this part of the explosive gas mixture, the gas mixture other extrusion expansion will not ignited. As the piston is further pushed upward, the remaining mixed gas combustion chamber will compression ignition combustion.

It is reported that the use of this Mazda SKYACTIV-X technology is expected to first engine equipped with the next generation of Mazda 3 (ie domestic Mazda 3Axela Angkesaila) model, and the model is expected to be launched in 2018.
