Specific embodiment
The concrete structure of the utility model is provided by following embodiment and attached drawing：
As shown in Figure 1：A kind of diesel engine exhaust heat management system of the utility model includes exhaust manifold, supercharging
Device sets pressure detecting mouth 1a, pressure detecting mouth 1a connection exhaust manifold pressure test devices, exhaust manifold on exhaust manifold 1
Pressure test device includes pressure test pipe 3 and the connection pressure sensor 4 being attached thereto；Booster 6 is installed by booster
Bolt 5 is mounted on 1 gas outlet of exhaust manifold；Exhaust gas flow control valve 7 is connected to by clip 8 on the exhaust outlet of booster 6,
And the angle control hole on 7 air inlet of exhaust gas flow control valve is aligned with 6 flange high scale of booster；The letter of pressure sensor 4
The control receiver port of number output terminal and exhaust gas flow control valve 7 is connect respectively with engine control module.
Fig. 2 is the schematic diagram of the exhaust manifold pressure test device of the utility model：One end of the pressure test pipe leads to
Sealing nut 2 is crossed to connect with the pressure detecting mouth 1a on exhaust manifold 1；Pressure sensor 4 is installed nut 9 by sensor and is welded
In the other end of pressure test pipe；Stent 10 is welded and fixed on the outside of sensor installation nut, the other end of fixing bracket 10 leads to
Nut is crossed to connect with engine cylinder body.
Fig. 3 is the schematic diagram of the exhaust gas flow control valve of the utility model：The exhaust gas flow control valve 7 includes motor
7a, valve block 7b, air inlet 7c, control receiver port 7d, valve block 7b pass through transmission shaft and motor 7a connect in valve body
It connects, motor 7a is connected with control receiver port 7d.
During utility model works, six channels of exhaust manifold are connect with engine cylinder body exhaust apertures, exhaust manifold pressure
The control sensor in pressure test sensor and exhaust gas flow control valve in force test device controls respectively with engine
Module connects, and when current exhaust gas flows through exhaust manifold, engine control module can check the pressure in exhaust manifold, exhaust gas
When reaching exhaust gas flow control valve by booster, engine control module is according to exhaust gas pressure size in the exhaust manifold of test
The angle that exhaust gas flow control valve should be opened is calculated, by the way that receiver port is controlled to communicate information to extraction flow control
Valve processed controls the rotational angle of motor, so as to control the opening angle of valve block, can increase resistance to exhaust after being opened due to valve block
Power, therefore pressure at expulsion will increase, delivery temperature can be increased with the raising of pressure at expulsion.
