FUEL TYPE ESTIMATION SYSTEM, DATA ANALYSIS APPARATUS, AND CONTROL APPARATUS FOR FUEL SUPPLY APPARATUS

Provided are a fuel type estimation system, a data analysis apparatus, and a control apparatus for a fuel supply apparatus. The fuel type estimation system configured to estimate a type variable related to a type of fuel in an engine system including an engine and a fuel supply apparatus includes a storage device and an execution device. The storage device is configured to store a mapping that uses, as inputs, input variables including an engine variable related to a condition of the engine and outputs the type variable. The execution device is configured to acquire the input variables, and estimate the type variable by applying the acquired input variables to the mapping. 一种燃料种类推定系统、数据解析装置、燃料供给装置的控制装置，所述燃料种类推定系统构成为推定与发动机装置中的燃料的种类相关的种类变量，所述发动机装置包括发动机和燃料供给装置，所述燃料种类推定系统包括存储装置和执行装置。所述存储装置构成为存储将包括与所述发动机的状态相关的发动机变量的输入变量作为输入，并且将所述种类变量作为输出的映射。所述执行装置构成为取得所述输入变量，并且构成为将所取得的所述输入变量适用于所述映射来推定所述种类变量。
