The invention relates to a system and method for use in a homogeneous charge compression ignition (HCCI) combustion engine that is preferably equipped with an exhaust gas recirculation device. This system and method enable an improved adjustment of the temperature level inside the combustion chamber. In addition to adjusting the temperature by using the exhaust gas recirculation device, an influencing of the temperature, which is independent thereof, ensues based on the compression of the induced fresh air by the exhaust gas turbocharger. An increase in temperature is maintained even after the compressed air is expanded on a throttle valve, and this increase in temperature can, in the end, be used for influencing the energy content inside the combustion chamber.

The invention provides a Jet solder vessel. The Jet solder vessel can prevent tin soldering oxygenation injected from the nozzle. A cover body part has an opening for inserting of the nozzle part and a lateral wall located at the outside of the opening, the cover body part covers one part of the soldering tin storage part. A supply tube has a plurality of supply ports for supplying nitrogen to the lateral wall side, the supply tube is provided between the opening and the lateral wall in a mode of enclosing the surrounding of the opening. Therefore, the nitrogen supplied from the supply ports faces to the lateral wall to supply, and is stored between the nozzle part, the lateral wall and the liquid level of the soldering tin. The gas density of the stored nitrogen becomes higher. The nitrogen with high gas density ejects from the opening, and injects the nitrogen to the soldering tin injected from the nozzle part. Therefore, the soldering tin oxygenation can be prevented. As a result, imperfect bridging and imperfect solder projection caused by that the soldering tin is adhered outside the prescribed positions.
