Title:
INTAKE AIR AMOUNT MEASUREMENT DEVICE AND ENGINE
Document Type and Number:
WIPO Patent Application WO/2021/193036
Kind Code:
A1
Abstract:
[Problem] To provide: an intake air amount measurement device capable of preventing a measurement result of a flow rate of intake air flowing through an intake air pipe from depending on a shape of the intake air pipe and stably measuring the flow rate of the intake air; and an engine. [Solution] An intake air amount measurement device 200 is provided with: an intake air distribution means 3 for distributing intake air CYL to cylinders 11, 12, 13, and 14; a temperature detection means 202 for detecting a temperature Ti of the intake air CYL; a pressure detection means 201 for detecting a pressure Pi of the intake air CL; and a computation unit 100 for computing an intake air amount mfcyl of the intake air CYL on the basis of the temperature Ti transmitted from the temperature detection means 202 and the pressure Pi transmitted from the pressure detection means 201. The temperature detection means 202 detects the temperature Ti of the intake air CYL in a region W extending between a first branch part 31 and a second branch part 32 inside the intake air distribution means 3.
