させた。[Detailed Description of the Invention] [Summary] An opening at one end of a hollow part in a cylinder including a combustion chamber, an exhaust manifold, or an exhaust valve in a four-cycle spark-ignition piston internal combustion engine for a vehicle such as an automobile. A non-flammable liquid injection device and a supply device are added nearby, and non-flammable liquid is injected and supplied at appropriate injection timings to reduce the silent load inside the combustion chamber near the exhaust valve. .

面部分の熱負荷が増大していた。[Prior art] As the output increases, the exhaust valve temperature rises, and soon the temperature of the inner surface of the combustion chamber near the exhaust hub at the time of ignition becomes higher than the temperature of the mixture near the center at the time of ignition. . Therefore, the combustion speed of the air-fuel mixture near the exhaust valve is faster than that of other air-fuel mixtures, and the combustion speed of the air-fuel mixture near the exhaust valve is faster than that of other air-fuel mixtures. As the proportion of the air-fuel mixture increased, the heat load on the inner surface of the combustion chamber near the exhaust valve increased.

現していた。As a countermeasure to the above, the combustion speed of the entire mixture was lowered by increasing the specific heat due to enrichment of the air-fuel ratio and increase in the amount of liquid mixed in, but a part of the mixture near the exhaust valve was Combustion still occurs under high pressure conditions, and in order to reduce the proportion of this air-fuel mixture, it was necessary to progressively increase the specific heat of the entire air-fuel mixture beyond the increase in the amount of intake air. In other words, high output was achieved by reducing durability and thermal efficiency due to increased heat load on the inner surface of the combustion chamber near the exhaust valve.

だった。In addition to the sodium-filled valve, which improves heat conductivity to the details, there may have been a device that cooled the hollow part of the exhaust valve by flowing air into it, or if air was being cooled by directing air from the exhaust valve head to the fast part of the exhaust valve. The cooling capacity was insufficient.

度が小さい。In the invention of Patent Registration No. 1222085 that reduces the compression stroke by prematurely closing the intake rotary valve before the bottom dead center, the increase in heat loss of the exhaust valve during the intake and compression strokes is small, and the increase in intake air amount is limited. Because of this, the degree of high output is small.

室内面の熱負荷を減少させる事を目的とする。The present invention utilizes a four-cycle spark ignition piston system that operates from the time when the temperature of the inner surface of the combustion chamber of the exhaust valve at the time of ignition approaches the temperature at the time of ignition of the air-fuel mixture other than the vicinity of the exhaust valve to the time of output when the temperature reaches a high temperature. The purpose is to reduce the heat load on the inside of the combustion chamber near the exhaust valve of an internal combustion engine.

Sensors that measure indicators related to the calorific value of combustion gas, such as the degree of accelerator pedal depression, intake flow rate, throttle valve opening, or intake pipe pressure, and knocking sensors can be used.

する。When a liquid is injected into the combustion gas in the cylinder, the temperature of the combustion gas decreases due to the heat of vaporization and the increase in the specific heat of the combustion gas, and the temperature inside the cylinder and combustion chamber also decreases, and the exhaust valve in particular decreases in temperature. Furthermore, when liquid is injected directly into the exhaust valve, the temperature of the exhaust valve decreases due to the heat of vaporization and a decrease in the temperature of the nearby gas. Further, even if the liquid is supplied to the hollow part within the exhaust valve, the temperature will be lowered due to the heat of vaporization or the decrease in air temperature.

の熱負荷が減少する。When the temperature of the inner surface of the combustion chamber of the exhaust valve at the time of ignition becomes lower than the temperature of the air-fuel mixture near the center at the time of ignition due to cooling by the above-mentioned means, the combustion speed of the air-fuel mixture near the exhaust valve decreases to the temperature near the center. The proportion of the air-fuel mixture near the exhaust valve that burns at the beginning of combustion is slower than that of the air-fuel mixture, and burns under high pressure conditions before the piston descends. Since the air-fuel mixture is combusted, the heat load on the inner surface of the combustion chamber near the exhaust valve is reduced.

噴射すると、燃焼ガスの比熱が増加して、燃焼ガス圧力
が低下して、排気行程時の負の仕事量が減少する。When a liquid is injected into the combustion gas in the cylinder after the exhaust valve is opened, the specific heat of the combustion gas increases, the combustion gas pressure decreases, and the negative amount of work during the exhaust stroke decreases.
第１図、及び第２図により説明する。 This will be explained with reference to FIGS. 1 and 2.

前の高圧条件で燃焼する混合気部分の内の排気バルブ付
近の混合気部分の割合が減少して、熱負荷が減少する。Even during ignition at high output, the internal surface of the combustion chamber other than the vicinity of the exhaust valve transfers the heat of the air-fuel mixture that is in contact with it to the outside of the combustion chamber, causing heat loss. However, despite the heat loss to the air-fuel mixture during the intake stroke and part of the compression stroke, and the heat loss due to heat conduction to the valve seat, the exhaust valve temperature remains constant.
Due to the increase in the calorific value of the combustion gas, the temperature of the mixture eventually becomes higher than the temperature at the time of ignition. As a result, the heat load increases, so by injecting or supplying non-flammable liquid to the exhaust valve to lower the temperature, supercharging or increasing the compression ratio will increase the combustion speed of the mixture. Also, the proportion of the air-fuel mixture near the exhaust valve among the air-fuel mixture that burns under high pressure conditions before the piston descends in the early stage of combustion is reduced, and the heat load is reduced.

する方法を併用したりする事が望ましい。Furthermore, in order to prevent the pressure from increasing significantly due to combustion of a large amount of air-fuel mixture before top dead center, in addition to the above-mentioned means, a method of increasing the specific heat of the air-fuel mixture to reduce the combustion speed may be used. It is desirable to use a method of setting the ignition timing so that the ignition timing approaches top dead center.

から傘部近くまである物が望ましい。In order to lower the temperature of the exhaust valve, there are two methods: a means for lowering the temperature of the exhaust valve stem head and a part, as in the first means described in the column of means for solving the problem, and a second means as described above. There is a means to lower the temperature of the exhaust manifold side and the shaft part of the exhaust valve head part, as shown in FIG. If the injection timing is not set within the valve opening period, the specific heat of the combustion gas in the cylinder will increase and the output will decrease. Further, in the second means, the injection timing is set during the exhaust valve closing period. In the third means, the nonflammable liquid may be injected or mixed into air and supplied during the exhaust valve closing period, or may not be limited to the exhaust valve opening/closing period. Further, the opening at one end of the hollow portion in the exhaust valve may be provided in the shaft portion or the umbrella portion, and it is desirable that the hollow portion extends from the shaft portion to near the umbrella portion.

A device (7) indicating the amount of heat may be provided, and the amount of injection of the nonflammable liquid or the amount of the mixture of the nonflammable liquid and air to be supplied may be determined according to the value.

排気ガスに影響を与えない。If the injection timing is set from the bottom dead center after the exhaust valve opens to just before the intake valve opens using the first method, nonflammable liquid will be injected after the high-pressure combustion gas is injected. The injection pressure of the device (2) can be reduced, and the device can be made smaller. Since the exhaust valve is closed, the device can be made smaller by using the second method, but the steam vaporized by the heat of the exhaust valve absorbs the specific heat of the high-pressure and high-temperature exhaust gas that is ejected during the next exhaust stroke. In order to lower the pressure and temperature by increasing the pressure, the amount of increase in boost pressure decreases with an exhaust-driven supercharger, and there is no effect with a mechanically-driven supercharger. Does not affect exhaust gas.

分の比熱の減少量だけ熱効率か向上する。The heat load on the inside of the combustion chamber in the vicinity of the exhaust valve is reduced depending on the amount of injected or supplied nonflammable liquid of the first, second, or third means. Therefore, it becomes possible to increase the amount of intake air, that is, to increase the output, in accordance with the amount of reduction in the heat load. Furthermore, by supplying a rich air-fuel ratio or reducing the amount of non-flammable liquid mixed in, the thermal efficiency will be improved by the corresponding reduction in specific heat.
また、第１の手段では、排気行程時の負の仕事量か減少
