exhaust valve

Voorbeeldzinnen

1. Variable valve timing system (if applicable and where intake and/or exhaust):2.4.3.1.
2. The exhaust back-pressure or restriction must follow the same criteria as above, and may be set with a valve.
3. Quick response valve — such as the valve of an exhaust brake system of 60 mm in diameter, operated by a pneumatic cylinder with an output of 120 N at 4 bars.
4. The valve is opened when the exhaust gas pressure, measured at l00 mm at least downstream from the intake flange, reaches a value between 0,35 and 0,40 bar.
5. Variable valve timing system (if applicable and where intake and/or exhaust)3.2.4.3.1. Type: continuous or on/off3.2.4.3.2. Cam phase shift angle:3.2.5. Porting configuration3.2.5.1.
6. Quick response valve — such as the valve of an exhaust brake system of 60 mm in diameter, operated by a pneumatic cylinder with an output of 120 N at 4 bars. The response time, both when opening and closing, must not exceed 0,5 s.
7. Valve timing2.4.1. Maximum lift and angles of opening and closing in relation to top dead centre or equivalent data:2.4.2. Reference clearances and/or setting ranges (1)2.4.3. Variable valve timing system (if applicable and where intake and/or exhaust):2.4.3.1. Type: continuous or on/off2.4.3.2. Cam phase shift angle:2.5. Porting configuration2.5.1.
8. All electrical cables shall be so located that no part can make contact with any fuel line or any part of the exhaust system, or be subjected to excessive heat, unless suitable special insulation and protection is provided, as for example to a solenoid-operated exhaust valve.
9. In the case of an emission control monitoring system principally based on monitoring the NOx level by sensors positioned in the exhaust stream, the manufacturer may choose to directly monitor certain system functionalities (e.g. interruption of dosing activity, closed EGR valve) for the determination of compliance.
