According to foreign media reports, Purdue University researchers are developing automotive pre-combustion chamber technology to replace traditional spark plugs. The technology used in jet aircraft will soon be applied to private cars and other cars. The pre-combustion chamber is filled with a mixture of fuel and air. The mixture is ignited and then burned. The small hole at the bottom of the combustion chamber releases a powerful flame jet, penetrates the main combustion chamber, and ignites. Compared with the traditional spark ignition method, this method has a larger ignition area and rapid flame spreading speed, which can improve the overall combustion efficiency. The technical research objects include passive and active pre-combustion chamber. For the former, the main combustion chamber mixture undergoes a compression stroke and is pushed into the pre-combustion chamber through small holes. For the latter, additional fuel is used in the pre-combustion chamber to promote lean combustion in the main combustion chamber. Li Qiao, associate professor of aerospace at the Purdue University School of Engineering, said, "Purdue University has great potential in automotive technology and future engine research. Purdue University researchers in the field of engineering and science collaborate to develop innovative solutions. The pre-combustion chamber injection ignition technology is One of the achievements, Qiao also said that the technology has excellent performance and has been used in large-bore natural gas engines and some F1 racing cars, but has not yet been used in gasoline engines. Li Qiao also said, "Due to the competition of electric vehicles, the automobile industry is under pressure to optimize engines. Several automobile engine companies have begun to explore passenger car pre-combustion chamber technology." Qiao is currently working with the industry to design and optimize the passiveness of gasoline engines Type and active type pre-combustion chamber.
