Double w-shaped combustion chamber applicable to opposed injection

Abstract

The invention provides a double w-shaped combustion chamber applicable to opposed injection. The double w-shaped combustion chamber applicable to the opposed injection is characterized in that a w-shaped pit is formed in the center position of each of an air feeding side combustion chamber and an air exhausting side combustion chamber, wherein injected fuel oil spray guide structures are arranged at incisions, adjacent to a first oil injector and a second oil injector at two sides, of the air feeding side combustion chamber and the air exhausting side combustion chamber; a certain included angle is formed between the injected fuel oil spray guide structures at two sides of the air feeding side combustion chamber and the air exhausting side combustion chamber and a center line of the combustion chambers; the injected fuel oil spray guide structures are staggered and can correspondingly guide two injected fuel oil sprays to two sides of the double w-shaped combustion chamber. The double w-shaped combustion chamber applicable to the opposed injection has the following advantages: the problem of injected fuel oil spray collision caused by the opposed injection of the double oil injectors can be effectively avoided; the air utilization rate of the injected fuel oil spray can be increased on the premise that the capacity and compression ratio of the combustion chamber are unchanged, thus the oil-air mixing effect of an opposed injection type combustion system can be improved, and as a result, the combustion performances of double opposed engines can be improved.

Description

technical field [0001] The invention belongs to the technical field of double opposed two-stroke engines, and in particular relates to a double ω-type combustion chamber suitable for opposed injection. Background technique [0002] The quality of the combustible mixture in the cylinder directly affects the effect of fuel combustion, and then determines the power, economy and emission characteristics of the engine. For the opposed two-stroke engine (OPOC engine), it adopts the structural design of opposed pistons and opposed cylinders, and organizes the combustion of combustible mixture in the cylinder through the working mode of direct-flow scavenging and double injectors opposed injection. Formation and combustion process. Since there are no components such as cylinder heads and valve trains, the composition of its combustion system has two obvious features compared with traditional engines: the first feature is that the combustion chamber is formed by the combination of t...
