Embodiment Construction

[0066] Embodiments of the present invention will be described below with reference to the drawings.

[0067] Figure 1 to Figure 8(B) Any of the figures shows a common rail type vertical multi-cylinder diesel engine according to an embodiment of the present invention.

[0068] The engine is briefly described below.

[0069] The width direction of the cylinder block 2 or the cylinder head 10, the axial direction of the crankshaft 1, and the axial direction of the cylinder are taken as a horizontal direction, a front-rear direction, and a vertical direction, respectively. Such as figure 1 As shown, the cylinder block 2 has an upper portion to which the cylinder head 10 is mounted. The cylinder head 10 has an upper portion on which a cap 11 is mounted. A radiator 25 and an engine cooling fan 4 are provided in front of the cylinder block 2 . The engine cooling fan 4 is driven by the crankshaft 1 via a belt transmission 17 arranged in front of the cylinder block 2 . Arranged ...

Abstract

The present invention has an object to provide a vertical multi-cylinder diesel engine capable of conveniently protecting a common rail and its parts. On the assumption that a width direction of a cylinder block (2) is taken as a horizontal direction, when arranging the common rail (3) horizontally lateral of the cylinder block (2), there is disposed above the common rail (3) a passage forming means (23) which is the alternative of an intake air distributing means (5) and an exhaust air converging means (22). The passage forming means (23) above the common rail (3) may be formed into a box-shaped structure with no branch pipe. Further, an engine cooling fan (4) may be arranged in front of the common rail (3) so as to pass cooling air below the passage forming means (23) above the common rail (3).

Description

technical field [0001] The invention relates to a vertical multi-cylinder diesel engine. Background technique [0002] The example of traditional multi-cylinder diesel engine and the present invention are provided with a common rail (referring to Patent Publication No.2001-159381, as figure 1 and figure 2 shown). [0003] The common rail is subjected to a large internal pressure when the engine is running, so it is necessary to prevent the common rail from cracking or being damaged. Furthermore, since a pressure sensor or the like is connected to the common rail, it is also necessary to prevent the pressure sensor or the like from being damaged. In general, however, there is as yet no means for conveniently protecting the common rail and its components. [0004] The conventional technology described above has a problem that the common rail and its components are easily damaged. [0005] There is no easy means of securing the common rail and its components. Therefore, ...
