Problems solved by technology

However, the air inlet, air outlet, and vacuum port of the anti-surge valve of this structure use a pipeline to communicate with the air intake system, the pipeline is complicated, and the actual production and application cost is relatively high.
In addition, this structure uses a direct connection between the throttle valve and the engine intake pipe, and can only rely on the opening of the EGR to manually set the corresponding intake air volume through calibration, failing to realize the measurement and accuracy of the intake air volume of the engine. control, it is easy to cause fluctuations in boost pressure, causing pipeline intake vibration, and even turbocharger surge and other faults

Abstract

The invention relates to the technical field of engines, in particular to an anti-surge gas engine supercharging system. Including anti-surge valve assembly, anti-surge valve outlet connection pipe assembly and anti-surge valve vacuum port connection pipe assembly, the air inlet of the anti-surge valve assembly is integrated and installed on the engine intake pipe, The air outlet of the anti-surge valve assembly is connected to the first air intake connection pipe through the anti-surge valve air outlet connection pipe assembly, and the vacuum port of the anti-surge valve assembly is connected through the anti-surge valve vacuum port connection pipe The assembly is connected with the intake elbow behind the throttle body assembly. The anti-surge valve assembly is integrated and assembled on the engine intake pipe, which saves the connection pipeline of the anti-surge valve intake port and makes the engine layout more compact.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an anti-surge gas engine supercharging system. Background technique [0002] The gas engine supercharging system is mainly applied to the natural gas exhaust gas turbocharged engine equipped with a throttle valve, and the existing natural gas engine supercharger usually has a surge problem. [0003] The invention patent with the authorized notification number CN104696113 discloses a gas machine and its air intake device. The pipeline connecting pipe is provided with an anti-surge valve for controlling the conduction state of the pipeline connecting pipe. The engine runs at high speed and the throttle valve tends to When it is closed, the anti-surge valve is turned on, otherwise the anti-surge valve is normally closed to prevent the occurrence of surge and improve the transient response under the premise of ensuring the steady-state performance of the gas machine. However, the ai...
