  Therefore, when a collision object enters from the front side of the vehicle 1, the collision object contacts the intercooler 24, and the collision object enters the fuel system (low pressure fuel supply path, high pressure fuel supply path) including the high pressure fuel pump 11. There is no contact. Therefore, even if a collision object enters, damage to the fuel system such as the high-pressure fuel pump 11 can be suppressed without providing a dedicated protective member.

  And since the intercooler 24 is fastened to the bracket 9b of the intake manifold 9, and the protrusion 9a as a support portion is formed on the intake manifold 9, when the intercooler 24 receives an impact due to the entry of a collision object, The posture of the intercooler 24 can be maintained by being supported by the intake manifold 9.

  The engine 2 described above is supported by a side member (mount) of the vehicle body via a bracket.

  The support status of the engine 2 will be described with reference to FIGS.

  As shown in FIG. 6, a pair of left and right side members 51 extending in the front-rear direction of the vehicle 1 are provided at the front portion of the vehicle 1 where the engine 2 is supported. The front ends of the pair of side members 51 of the vehicle 1 are connected by a front end cross member 52. Mounted to the pair of side members 51 is a mount 53 to which a support member (a bracket 36 described later) of the engine 2 is attached.

  An engine mount (mount 53) is fixed to the side member 51 on the chain case side (lower side in FIG. 6) of the engine 2, and a transmission mount (mount 53) is fixed to the opposite side (upper side in FIG. 6). The chain case side of the engine 2 is connected to the side member 51 (vehicle body) by the engine mount (mount 53), and the opposite side is connected to the side member 51 (vehicle body) by the transmission mount (mount 53) via the transmission 20.

  Since the engine mount (mount 53) and the transmission mount (mount 53) are the same member, they are described as the mount 53 below.

  The mount 53 is provided with a base 55 fixed to the side member 51, and an elastic material of an insulator is connected to the base 55. The insulator case that holds the elastic material is provided with a bolt attachment portion 56 to which a support member of the engine 2 (a bolt 39 of a bracket 36 described later) is fixed.

  As shown in FIG. 5, brackets 36 for attaching the engine 2 to the mounts 53 of the side members 51 are disposed on the left and right upper portions of the engine body 5 (chain case, transmission) in the vehicle width direction. The bracket 36 has a mounting portion 37 fixed to the mount 53, and the mounting portion 37 is provided with two bolts 39. The bracket 36 is provided with a fixed base 38 that is integral with the mounting portion 37, and the fixed base 38 is fixed to the engine body 5 (chain case, transmission) above the mounting portion 37.

  The fixing base 38 of the bracket 36 is fixed to the engine body 5, and the two bolts 39 of the mounting portion 37 of the bracket 36 are respectively fixed to the bolt mounting portions 56 of the mounts 53 of the pair of left and right side members 51. As a result, as shown in FIG. 5, the engine 2 is supported by the vehicle 1 with an inclination angle θ with respect to the vertical direction with the upper portion of the engine 2 positioned on the rear side of the vehicle 1 with respect to the lower portion. The

  Since the engine 2 is supported on the vehicle 1 with the upper part positioned at the rear side with the inclination of the inclination angle θ, when a collision object enters from the front of the vehicle 1 and collides with the intercooler 24, the fixed base of the bracket 36 is fixed. The upper portion of the engine 2 is tilted so as to be located further on the rear side in the range of elastic deformation of the elastic material of the insulator via the fixing portion (upper portion) 38 of the engine body 5. Thereafter, the bracket 36 is broken and detached from the side member 51, and the upper portion of the engine 2 is further tilted to the rear side, so that the engine 2 can be withdrawn accurately and damage to the fuel system can be suppressed.

  As an example when a collision object enters, a situation when the vehicle 1 equipped with the engine 2 described above collides with a large vehicle will be described with reference to FIG.

  FIG. 7 shows an explanation of the situation at the time of collision. FIG. 7 (a) shows a state in which the engine room of the vehicle 1 comes under the underbar as a collision object and the engine 2 comes into contact with the underbar. ) Is a state in which an underbar further enters the engine 2 side.

  The state of FIG. 7 is a front view of the engine 2 when the engine 2 is viewed from the right side in the vehicle 1 forward direction, and the right side in the figure is the front side of the vehicle 1 in the front-rear direction.

  As shown in FIG. 7A, when the vehicle 1 collides with a large truck or the like parked forward, an underbar 41 (impact object) such as a large truck moves from the front side of the vehicle 1 as the vehicle 1 moves forward. Enter the room. That is, the underbar 41 such as a large truck positioned higher than the bumper of the vehicle 1 enters the engine room.

  The underbar 41 that has entered from the front side of the vehicle 1 comes into contact with the lower part 34 a of the heat exchange part 34 of the intercooler 24. Therefore, even if the underbar 41 enters, the fuel system including the high-pressure fuel pump 11 is not directly impacted, and damage to the fuel system can be suppressed.

  When the under bar 41 comes into contact with the lower part 34a of the heat exchange part 34 of the intercooler 24 and the vehicle 1 further moves forward, the lower part 34a of the heat exchange part 34 is pushed by the under bar 41, and the intake manifold 9 (provided in the intake manifold 9). The intercooler 24 is rotated in the clockwise direction in the drawing until it comes into contact with the projection 9a).

  Further, due to the impact force acting on the intercooler 24, the upper part of the engine 2 is tilted rearward within the range of elastic deformation of the elastic material of the insulator through the fixing part (upper part) of the fixing base 38 of the bracket 36 to the engine body 5. It is done.

  As shown in FIG. 7 (b), the lower part 34a of the heat exchanging part 34 of the intercooler 24 is in contact with the intake manifold 9 (the upper part of the engine 2 is rearward in the range of elastic deformation of the elastic material of the insulator). When the under bar 41 further enters (in a tilted state), the bracket 36 is broken and detached from the side member 51 in a state where the rotation of the intercooler 24 is prevented by the intake manifold 9, and the upper portion of the engine 2 is further rearward. The engine 2 is moved backward by being pushed to the side. At the same time, the underbar 41 moves relatively upward on the left side in the drawing along the heat exchanging portion 34 of the intercooler 24.

  For this reason, as the vehicle 1 moves forward, the engine 2 can be retracted by accurately tilting the engine 2, and the engine body 5 can be retracted from the underbar 41.

  Therefore, after the fuel system is protected by the intercooler 24, the engine 2 is tilted accurately to retreat the fuel system (low pressure fuel supply path, high pressure fuel supply path) from the under bar 41, and even if no protective member is provided, the under bar 41 does not contact the fuel system (low pressure fuel supply path, high pressure fuel supply path) including the high pressure fuel pump 11. Thus, when the vehicle 1 collides with a stopped large truck or the like, the fuel system including the high-pressure fuel pump 11 is not damaged and fuel leakage does not occur.

  The internal combustion engine (engine) 2 of the vehicle 1 described above can receive an impact when the underbar 41 contacts the intercooler 24 when the underbar 41 of a large vehicle enters. The engine 2 can be retracted by precisely tilting the engine 2, and the engine body 5 can be retracted from the underbar 41. For this reason, it becomes possible to minimize damage to the fuel system including the high-pressure fuel pump 11 without providing a protective member or the like.

  INDUSTRIAL APPLICABILITY The present invention can be used in the industrial field of an internal combustion engine of a vehicle capable of accurately protecting a fuel system against the entrance of an impact object.
