摘要： A fuel injection controller for an internal combustion engine. The engine includes a fuel vapor treatment device having a collector for collecting fuel vapor generating in a fuel tank; a purge line that introduces purge gas into an intake passage of the engine, the purge gas being a mixture of fuel vapor released from the collector and air; and a purge valve provided in the purge line to adjust flow rate of the purge gas. The fuel injection controller corrects an amount of fuel injected from an fuel injection valve based on an amount of fuel vapor contained in the purge gas flowing into a combustion chamber of the engine. The fuel injection controller comprises an estimation section for estimating the inflow amount of the purge gas flowing into the combustion chamber based on a passed amount of purge gas that has passed through the purge valve and a compensation value for compensating transportation delay. The compensation value is set based on internal pressure of the intake passage and velocity of intake air that flows into the combustion chamber.

摘要翻译： 一种用于内燃机的燃料喷射控制器。 发动机包括燃料蒸汽处理装置，其具有用于收集在燃料箱中产生的燃料蒸汽的收集器; 吹扫管线，其将净化气体引入到发动机的进气通道中，净化气体是从集气器和空气中释放的燃料蒸汽的混合物; 以及设置在净化管线中的净化阀，以调节净化气体的流量。 燃料喷射控制器基于流入发动机的燃烧室的吹扫气体中所含的燃料蒸汽的量来校正从燃料喷射阀喷射的燃料量。 燃料喷射控制器包括：估计部，用于基于通过吹扫阀的净化气体的通过量和用于补偿运输延迟的补偿值来估计流入燃烧室的吹扫气体的流入量。 补偿值基于进气通道的内部压力和流入燃烧室的进气的速度来设定。
