CONSTITUTION: A starting control method of FFV engine comprises: an emergency determining step(S10) for determining whether an emergency starting is necessary or not based on the number of starting trials; a criterion determining step(S20) for determining a current ethanol concentration learning value is a predetermined concentration value or not when determined that emergency starting is necessary or not; a concentration swing step(S30) for trying to start an engine according to a result of performing the criterion determining step; and a starting determining step(S40) for determining the engine is started or not by a result of performing the concentration swing step. [Reference numerals] (AA) Start; (CC) Set an ethanol concentration in a range of concentration less than 75% and try to start an engine; (DD) Set an ethanol concentration in a range of concentration over 75% and try to start an engine; (EE) End; (S10) Engine fails to start during three times of attempts?; (S20) Current ethanol concentration learning value >= 75% ?; (S40) Engine started?; (S51) Reset the ethanol concentration in the range of concentration over 75% and try to start the engine; (S52) Reset the ethanol concentration in the range of concentration less than 75% and try to start the engine; (S60) Learn the ethanol concentration

    • A control method of a gas engine system which can control an air/fuel ratio with high precision even for a low-calorie fuel gas having an easy-to-change colorific value. The gas engine system is also provided. When the fuel gas has a low calorie or the engine output is a heavy load, a part of the fuel gas in a fuel gas passage is branched, the fuel gas branched through a gas supply valve installed on the fuel gas passage and subjected to on/off control is passed through a supercharger-side gas supply passage and supplied to a mixer installed at the air inlet of the supercharger and having a structure for mixing the fuel gas with air at a specified ratio that provides gas concentration at lower flammability limit or below. Mixed gas from the mixer is supplied to the supercharger and the remaining fuel gas is passed through a cylinder-side gas supply passage provided with a gas compressor for compressing fuel gas and supplied to a fuel flow rate control valve which then controls the quantity of fuel gas such that the mixed gas has a predetermined air/fuel ratio. When the fuel gas has high calorie or when the engine output is a light load, the gas supply valve is closed and the fuel gas is supplied only to the cylinder-side gas supply passage.
    • 即使对于具有易变色度的低热量燃料气体也能够高精度地控制空燃比的燃气发动机系统的控制方法。 还提供燃气发动机系统。 当燃料气体具有低卡路里或发动机输出是重负载时,燃料气体通道中的燃料气体的一部分被分支,燃料气体通过安装在燃料气体通道上的气体供给阀分支并经过 /关闭控制通过增压器侧气体供给通道并供给到安装在增压器的进气口处的混合器,并且具有以提供低燃烧极限气体浓度的特定比例将燃料气体与空气混合的结构,或 下面。 来自混合器的混合气体被供给到增压器,剩余的燃料气体通过设置有用于压缩燃料气体的气体压缩机的气缸侧气体供给通道,并被供给到燃料流量控制阀,然后控制燃料量 使得混合气体具有预定的空气/燃料比。 当燃料气体具有高热量时或者当发动机输出为轻负荷时,气体供给阀关闭,并且燃料气体仅供给到气缸侧气体供给通道。

    • Upon a start of the internal combustion engine (10), a starting system causes an injector (41) to inject fuel into and causes an ignition plug (45) to ignite a mixture in a cylinder stopped in the expansion stroke, and causes the injector (41) to inject fuel into and causes the ignition plug (45) to ignite a mixture at or in the vicinity of the compression TDC in a compression-stroke cylinder that follows the expansion-stroke cylinder. When the engine coolant temperature is equal to or higher than a predetermined temperature, and when the cylinder stopped in the compression stroke is stopped in the first half of the compression stroke, the starting system retards the fuel injection timing for the compression-stroke cylinder.
