Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-cylinder engine provided with an electric device for an engine. 2. Description of the Related Art Various electric devices are attached to a main body of a multi-cylinder engine. For example, an alternator for charging a battery that supplies power to an electric device provided in an automobile is disposed on a side of a crank pulley end of an engine body, and its electrode terminal is disposed on a side surface or a back surface of the alternator. That was common. [0003] However, the electrode terminal of the conventional alternator is provided at a position directly opposed to a vehicle body frame, a radiator, or the like. Short circuit. [0004] The present invention has been devised to solve such problems of the prior art, and its main objects are as follows.
It is an object of the present invention to provide a multi-cylinder engine improved so that electrode terminals of an electric device for an engine hardly come into contact with a vehicle body in a collision. According to the present invention, a multi-cylinder engine provided with an alternator 4 is provided with an electrode terminal 19 of the alternator .
The air- conditioning compressor is disposed at a position opposite to the end face of the intake manifold 15 in the cylinder row direction, and is located below a space between the end faces of the intake manifold in the cylinder row direction and the electrode terminals.
Suppressor 6 is arranged adjacent to the air cylinder row direction end face of the air-conditioning compressor, and the case 24 of the thermostat valve sites located below the intake manifold is assumed, characterized in that disposed . In this way, even if the vehicle body is deformed in the event of a collision, it is protected by the intake manifold or the like, so that the electrode terminals hardly come into contact with the vehicle body. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 shows an in-line multi-cylinder engine to which the present invention is applied as viewed from a crank pulley side. An oil pump 2 for a power steering device, a tensioner pulley 3, an alternator 4, a water pump 5 for cooling the engine, and a compressor 6 for air conditioning are arranged on the side of the crank pulley end of the engine body 1 of the in-line multi-cylinder engine from above. They are arranged in this order. These auxiliary machines are provided with a single (common) endless belt 13 wound between pulleys 7 to 11 and a crank pulley 12 provided on each of the auxiliary machines. Although they are collectively driven by power, the oil pump 2 for the power steering device, the alternator, and the 4 and the air conditioning compressor 6 are separated from the engine body 1 to the right in FIG. 1, the tensioner pulley 3 and the engine cooling water pump 5
Are disposed close to the engine body 1. In this manner, the plurality of accessories 2 to 6 are compactly arranged on one side of the engine body 1, and the plurality of accessories 2 to 6 can be reliably driven by one endless belt 13. ing. As shown in FIGS. 2 and 3, an intake manifold 15 is disposed on the side of the cylinder head 14 where these auxiliary devices are disposed. In addition, FIG.
The figure shows a state in which the alternator 4 is removed and all the other components are removed. This intake manifold 1
Reference numeral 5 denotes four independent intake pipes A1, A2, and A3 for each cylinder.
A4 is arranged in parallel in the cylinder row direction, and one end of each intake pipe A1, A2, A3, A4 is connected to the cylinder head 14, and the other end is connected to the cylinder head 1
After being extended in the direction away from 4, it is curved, extended downward along the side surface of the cylinder block 16, and further curved toward the cylinder block 16, and then toward the coupling end side with the cylinder head 14. That is, it extends upward, and has a shape that is entangled like a cochlea as a whole. At the center where the intake pipes A1, A2, A3 and A4 are wound, an intake collecting chamber connected to a throttle body and a rotary valve for changing the intake pipe length stepwise are provided. However, description of these will be omitted. As described above, the alternator 4 located in the middle of the plurality of auxiliary machines is separated from the engine body 1 to the right in FIG. 1. The alternator 4 is provided on a side surface of the cylinder block 16 via a bracket 17 for raising the height.
It is bolted up and down. The bracket 17 has a cooling water passage 18 connected to a cooling water pump.
Are formed. In this way, the bracket 17 is used not only as a raising member but also as a multifunctional member. On the end face of the alternator 4 on the side opposite to the pulley,
An electrode terminal 19 for connecting to a battery (not shown) is provided. The electrode terminal 19 is connected to the intake manifold 1
5, when the engine main body 1 is placed laterally with respect to the vehicle body, the body frame deformed at the time of collision abuts against the intake manifold 15, which serves as a protective barrier and serves as a protective barrier. The terminal 19 is prevented from contacting the vehicle body frame. A starter motor 21 is provided in a gap G between the intake manifold 15 and the cylinder block 16, and is located between the starter motor 21 and the air conditioning compressor 6 in the cylinder row direction. A thermo case 24 integrated with a hose port 23 and having a built-in thermostat valve is provided at a portion located below the intake manifold 15 with the alternator mounting bracket 1.
7 is attached to a part integrally formed. As described above, according to the present invention, it is possible to prevent an electrode terminal of an electric machine such as an alternator from coming into contact with a deformed body frame or the like at the time of a collision. This has a great effect on reducing the possibility of causing the next disaster.
