平均有効圧が増大されることを説明し“Ｃいる。For example, in a uniflow scavenging engine, in which air flows into a °C cylinder through a scavenging hole, and combustion gas in the cylinder is exhausted through an exhaust valve, conventionally, as a means to improve equivalent engine efficiency, It is widely known to slow down the C cylinder and increase the work of expansion in the C cylinder. In other words, Fig. 1 shows a pressure chart near the dead center of a uniflow scavenging engine, and the C indicated mean effective pressure is increased by opening the exhaust valve later than usual. Explain that “C is there.
いま、図示平均有効圧ｐｉと、第１図の斜一部に示すよ
うな有効仕事を増大させ得る余地Ｊ１とで、排気線図係
数１ｇｅＸ、を次式により定義する。Now, the exhaust diagram coefficient 1geX is defined by the following equation using the indicated mean effective pressure pi and the room J1 for increasing the effective work as shown in the diagonal part of FIG.

る。In the above formula, °C, qgex = 100% is Δpl = oo
kgf/cd, and indicates that there is no room to further increase the effective work by delaying the opening timing of the exhaust valve.

に到達することになる。1st! The figure shows the above exhaust diagram coefficient when the opening timing of the C exhaust valve is delayed in a uniflow scavenging type engine, and the changes in the fuel consumption rate based on the normal exhaust valve opening timing, respectively. This shows the results of analysis using computer simulation. As is clear from Fig. 2, by delaying the opening timing of the exhaust valve, the fuel consumption rate is reduced and the thermal efficiency is improved. Almost 100%
will be reached.

ことに伴なって掃気孔開時期をも遅らせようとする試み
が種々なされている。However, if the opening timing of the exhaust valve is delayed, the gas pressure inside the cylinder will be high when the scavenging hole opens, and the combustion gas will flow from the cylinder to the scavenging chamber. There is a risk that the flow will flow back and cause various problems. Therefore, in the past, various attempts have been made to delay the opening timing of the scavenging holes by delaying the opening timing of the exhaust valve.

いう問題があった。That is, in the past, various proposals have been made in which the scavenging air control valve provided on the outer periphery of the cylinder is used to open and close the scavenging air hole, and the operation of this scavenging air control valve is controlled by various means. There is. However, in all of these conventional proposals, the scavenging control valve is moved vertically or circumferentially along the cylinder liner.
Therefore, there was a problem in that it was not possible to increase the surface pressure on the sliding surface, and therefore it was not possible to prevent gas leakage in the cylinder.
