摘要: Supply of fuel is stopped when fuel pressure sensed by a pressure sensor provided upstream of a regulator is at a predetermined value or less to avoid abnormal combustion caused by improper adjustment of air/fuel ratio. Even slight variation of the fuel pressure is sensed by monitoring the fuel pressure in an interval after closing a fuel shut-off valve once opened to re-opening of it. In addition, an abnormal state in the fuel system is detected by comparing an accumulated value of amount of injected fuel and an estimated value of fuel consumption in the tank. Furthermore, the peak current value of the fuel injection valve is controlled so that, when the engine at a low temperature is started, lift load of the injection valve is larger than sticking force of the injection valve, thereby preventing such situation where the injection valve is frozen so that it cannot supply fuel to the engine. In this case, the engine can be smoothly started by simultaneously controlling the valve open time. Furthermore, the temperature of the regulator is properly maintained so that optimum function can be exhibited by controlling the flow rate of cooling water flowing through a water passage provided in the regulator for regulating the fuel gas pressure.
摘要翻译: 在设置在调节器上游的压力传感器检测到的燃料压力为预定值以下时,停止供给燃料,以避免由于空气/燃料比的不当调整引起的异常燃烧。 通过在关闭燃料切断阀一旦打开以重新打开之后的间隔中监视燃料压力来检测燃料压力的轻微变化。 另外,燃料系统中的异常状态是通过比较燃料喷射量的累积值和燃料消耗的估计值来检测的。 此外,控制燃料喷射阀的峰值电流值,使得当低温发动机开始时,喷射阀的升程负荷大于喷射阀的粘附力,从而防止了喷射阀 被冻结,使其不能向发动机供应燃料。 在这种情况下,可以通过同时控制阀打开时间来平稳地起动发动机。 此外,适当地保持调节器的温度,从而通过控制流过设置在用于调节燃料气体压力的调节器中的水通道的冷却水的流量来显示最佳功能。

摘要: A method for drying erythritol crystals having a moisture content of from 1 to 10% by weight to reduce to the moisture content of 0.15% by weight or below, which comprises drying under fluidized state wherein a temperature of a gas to be used in the fluidized drying is controlled within a range of from 10.degree. to 60.degree. C. at least until the moisture content of said crystals is reduced to 0.5% by weight or below.The moisture content of erythritol crystals (moisture content: 1 to 10% by weight) can be highly efficiently reduced to 0.15% by weight or below in a stable form without deteriorating the crystalline properties and form by fluidized drying said erythritol crystals with the use of a gas flow of a relatively low specific temperature.
