Problems solved by technology

[0013] The above-mentioned traditional technology for proposing a PCCI engine only discloses the basic structure of a traditional PCCI engine, but does not explain any technical details of increasing the compression ratio, whether it is to increase the height of the dead center of the upper stroke, or to prevent the natural ignition of the fuel before the piston reaches the dead center of the upper stroke

Embodiment Construction

[0038] Reference should now be made to the drawings, wherein like reference numerals are used to designate like or like components throughout the different drawings.

[0039] Figure 4 The cutaway diagram in demonstrates the operation of a conventional PCCI engine. Such as Figure 4 As shown, during operation of a conventional PCCI engine, intake air is introduced into the engine through intake manifold 8 . In intake manifold 8 , intake air is mixed with high-pressure fuel injected from injector 6 . Before the fuel is introduced into the combustion chamber 20, the fuel and air are mixed in the intake manifold 8, which is called "premixing" in the related art, and the premixed fuel and air in the above state are called "premixing". Premix".

[0040] When the inlet port 2 is open, the premix is ​​introduced into the combustion chamber 20 . In the combustor 20, the premix is ​​highly heated and compressed so that it has high temperature and pressure. When the piston 40 reac...

Abstract

PURPOSE: A premixed charge compression ignition engine structure and a premixed charge compression ignition-type reciprocating generator are provided to obtain a high compression ratio of 30 or so, to reduce energy loss, and to reduce heat loss. CONSTITUTION: A premixed charge compression ignition engine structure includes a suction port to which a suction valve is formed; an exhaust port to which an exhaust valve is formed; and a suction manifold connected to the suction port. An injector is formed to the suction manifold. In the premixed charge compression ignition engine structure, fuel and air are uniformly mixed from the suction manifold. The premixed charge compression ignition engine structure includes a cooling nozzle formed to the upper end of a combustion chamber; a cooling fluid pump(30) supplying a cooling fluid to the cooling nozzle; and a storage tank(28) storing the cooling fluid. Self-ignition is executed just when reaching a high compression ratio by injecting the cooling fluid to the combustion chamber under high pressure. In the premixed charge compression ignition engine structure, a first connecting rod(42) connected to a piston(40) is connected to a first support plate(43) and a second connecting rod(46) connected to a crankshaft(48) is connected to a second support plate(45). The first and second support plates are supported and joined by plural springs(44).

Description

technical field [0001] In general, the present invention relates to premixed compression ignition (PCCI) engines, and more particularly to a PCCI engine having a fuel injector in the intake manifold to provide fuel and air and ignites the premix naturally in the high temperature, high pressure fuel chamber without the use of a separate electric igniter; it has a structurally improved connecting rod with The spring, which works organically with other components of the PCCI engine. The present invention also relates to a PCCI reciprocating generator. When manufacturing the generator, a reciprocating generator unit is combined with the PCCI engine so that the working efficiency of the generator can be improved. Background technique [0002] Typically, in conventional gasoline engines, fuel and air are premixed to prepare a premix, which is then electrically ignited in the fuel chamber to produce the desired power. During the compression stroke, when a premix of fuel and air i...
