たことを特徴とするディーゼルエンジジの吸気装置。Two intake ports, one of which is a low-speed swirl port and the other a high-speed swirl port, a first intake passage that communicates with the low-speed swirl port of each of the above air pumps, and In a diesel engine intake system including a second intake passage that communicates with a high-speed port, a communication passage that communicates the first intake passage and the second intake passage is provided,
The intake passage upstream of the first intake passage communication portion with which one end of the communication passage communicates is formed longer than the intake passage upstream of the second intake passage communication portion with which the other end of the communication passage communicates.
The first intake passage is communicated with the low rotation SW1 port, and the first intake passage and the second intake passage are communicated via the communication passage, and the second intake passage and the high rotation port are communicated with each other through the communication passage. On the other hand, during high rotation, the intake passage is switched so that the intake passage upstream of the second intake passage communication section communicates with both intake ports and the communication between the first intake passage and the swirl port for low rotation is closed. An intake system for a diesel engine characterized by being equipped with a control device.
