Title:
LUBE OIL CONTROLLED IGNITION ENGINE COMBUSTION
Document Type and Number:
Japanese Patent JP2022180359
Kind Code:
A
Abstract:
To provide a lube oil controlled ignition (LOCI) engine capable of consistent ignition and efficient start of combustion.SOLUTION: First, lube oil is already indispensable for any combustion engine; hereafter, there is no need to carry a secondary fuel and to have to depend on an additional fuel system as in the case of dual-fuel technologies. Second, the ignition and the start of combustion utilize controlled autoignition of the lube oil to prevent the occurrence of abnormal combustion as experienced with the spark ignition technology. Third, the LOCI combustion is characterized by the traveling of a premixed flame; hence, the LOCI combustion has a controllable duration resulting in a wide engine load-speed window unlike the homogeneous charge compression ignition technology where the engine load-speed window is narrow. Adaptive intake valve closure may be used to control in-cylinder compression temperature to be high enough to realize the consistent auto ignition of the lube oil mist.SELECTED DRAWING: Figure 1
