    Abstract: A fuel injection device for a diesel engine adapted to perform a preliminary injection (1) and a main injection (2) to a combustion chamber (3), wherein the preliminary injection (1) is adjusted to begin within a valve overlap term (40).Within the valve overlap term (40), no intake air is introduced into the combustion chamber (3) or a little if any and the combustion chamber (3) contains a gas of high temperature. If the preliminary injection (1) is conducted into this gas of high temperature within the combustion chamber (3), a preliminary injection fuel vaporizes soon to thereby shorten the ignition lag of a main injection fuel with the result of improving the combustion.

    Abstract: 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.

    Abstract: In a governor device of a diesel engine, a control rack of a fuel injection pump is adapted to be controllably actuated by a balance between a governor spring and an engine revolution speed responsive means. A speed control member is adapted to be manipulated for adjusting a tension force of the governor spring. A fuel limiting actuation member serves to prevent an excessive fuel flow from being injected when the speed control member is manipulated for a quick acceleration. A quick acceleration state detecting means serves to detect a quickly accelerated state of the engine so as to selectively change over the fuel limiting actuation member to a fuel limiting position and to a fuel limitation cancelling position depending on the lapse of time.
