    • The present invention relates to an engine and a method for producing the engine.The engine is constructed as follows.The engine interlockingly operates a pump (39, 139) for feeding fuel under pressure, by power of a crank shaft (1). A pair of gears (32a) and (32b) are arranged to be attached to a gear attaching shaft (32). The paired gears (32a) and (32b) are attached to the gear attaching shaft (32). At least one gear (32a) of the paired gears (32a) and (32b) constitutes a gear train (14, 114) through which the power of the crank shaft (1) is transmitted to the pump (39, 139).The method for producing the engine is constructed as follows.The method uses a common part for each of the gear trains (14) and (114) so as to produce engines of an injection pump specification and a common rail specification and alternatively manufactures the gear trains (14) and (114) through the common part. It comprises attaching a pair of gears (32a) and (32b) to a gear attaching shaft (32) of the engine of every specification, making one gear (32a) of the paired gears (32a) and (32b) serve as a basic gear and the other gear (32b) serve as a second gear, employing the basic gear (32a) as the common part for each of the gear trains (14) and (114) and alternatively manufactures the gear trains (14) and (114) of the engines of the respective specifications through the basic gear (32a) of the common part.
    • 发动机及其制造方法技术领域本发明涉及发动机及其制造方法。 发动机的构造如下。 发动机联动地操作用于通过曲轴(1)的动力在压力下供给燃料的泵(39,139)。 一对齿轮(32a)和(32b)被布置成附接到齿轮连接轴(32)。 成对的齿轮(32a)和(32b)连接到齿轮连接轴(32)。 一对齿轮(32a)和(32b)中的至少一个齿轮(32a)构成齿轮系(14,114),曲柄轴(1)的动力通过该齿轮系传递到泵(39,139) )。 发动机的制造方法如下构成。 该方法为每个齿轮系(14)和(114)使用公共部件,以便生产喷射泵规格和共轨规格的发动机,并且可替代地通过公共部分制造齿轮系(14)和(114) 部分。 它包括将一对齿轮(32a)和(32b)连接到每个规格的发动机的齿轮连接轴(32)上,使一对齿轮(32a)和(32b)的一个齿轮(32a) )用作基本齿轮,另一齿轮(32b)用作第二齿轮,其中使用基本齿轮(32a)作为每个齿轮系(14)和(114)的公共部分,并且可选地制造齿轮 通过公共部分的基本齿轮(32a),相应规格的发动机的列车(14)和(114)。
