Description
본 고안은 항공기용 소형엔진의 공연비와 배기온도를 측정함에 있어 동시에 두 센서로 배기가스가 접촉할 수 있도록 소형엔진의 배기구에 일체형의 배기관을 구성한 것으로,The present invention is to construct an integrated exhaust pipe in the exhaust port of the small engine so that the exhaust gas can be contacted by two sensors at the same time in measuring the air-fuel ratio and exhaust temperature of the small engine for aircraft,
더욱 상세하게는 항공기용 소형엔진의 배기구보다 큰 일반 자동차용 엔진의공연비 센서를 사용하여 소형엔진의 공연비를 측정하고 동시에 온도측정을 용이하게 하며 소형엔진의 진동으로부터 두 센서를 보호하면서 배기가스가 원활히 배출될 수 있도록 하는 소형엔진 배기가스측정을 위한 공연비와 온도센서 일체형 배기관에 관한 것이다.More specifically, the air-fuel ratio sensor of a general automotive engine, which is larger than the exhaust port of a small engine for aircraft, is used to measure the air-fuel ratio of a small engine, facilitate temperature measurement at the same time, and protect the two sensors from vibration of the small engine. It relates to an air-fuel ratio and a temperature sensor integrated exhaust pipe for measuring a small engine exhaust gas that can be discharged.
종래의 항공기용 소형엔진에 대한 공연비 측정용 센서는 별도로 제작된 것은 없으며, 이를 위해 자동차용의 부피가 큰 공연비 센서를 사용해왔으며 소형엔진의 배기구 외부에 센서를 설치하거나 직접 소형엔진 배기구 끝에 붙여 측정하였고 온도센서 역시 배기구에 공연비 센서와는 별도로 장착하여 온도를 측정하였다.The conventional air-fuel ratio sensor for a small engine for aircraft is not manufactured separately. For this purpose, a bulky air-fuel ratio sensor for automobiles has been used, and a sensor is installed outside the exhaust port of a small engine or directly attached to the end of a small engine exhaust port. The temperature sensor was also installed in the exhaust port separately from the air-fuel ratio sensor to measure the temperature.
공연비 센서를 외부에 설치하여 측정하는 경우 배기가스가 대기의 공기와 섞여 측정의 정확도에 한계가 있으며 직접 소형엔진 배기구 끝에 붙여 측정하는 경우에는 배기가스의 배출을 방해하고 엔진진동에 의한 연결부가 파단되는 문제가 있었다.When measuring by installing an air-fuel ratio sensor externally, the exhaust gas is mixed with atmospheric air, which limits the accuracy of the measurement.When measuring directly at the end of a small engine exhaust port, it prevents the exhaust gas and breaks the connection part due to engine vibration. There was a problem.
본 고안은 소형엔진의 배기가스를 측정함에 있어 자동차용의 공연비 센서를 소형엔진에 맞게 구성할 수 있도록 하는 것이다.The present invention is to enable the air-fuel ratio sensor for automobiles to be configured for small engines in measuring exhaust gas of small engines.
본 고안은 온도센서와 함께 배기가스가 통과하는 배기관과 일체형으로 구성되어 배기가스의 배출을 방해하지 않으면서 소형엔진의 진동으로 인한 센서와 배기구의 연결부 파단을 방지하도록 하는 것이다.The present invention is integrally formed with the exhaust pipe through which the exhaust gas passes along with the temperature sensor to prevent breakage of the connection between the sensor and the exhaust port due to vibration of the small engine without disturbing the exhaust gas.
본 고안은 항공기용 소형엔진의 배기가스를 측정하기 위한 자동차용 공연비 센서와 온도센서가 연결되는 배기관과,The present invention is an exhaust pipe connected to the air-fuel ratio sensor and temperature sensor for automobiles for measuring the exhaust gas of a small engine for aircraft,
상기 배기관의 중앙에서 일측으로 돌출되어 소형엔진에 연결되는 소형엔진 배기가스 진입로와,A small engine exhaust gas inlet that protrudes from the center of the exhaust pipe to one side and is connected to the small engine;
상기 배기가스 진입로의 반대편에서 설치되며 진입된 배기가스를 배출시키는 배기가스 배출구를 동시에 구성할 수 있도록 함을 특징으로 하는 것이다.It is installed on the opposite side of the exhaust gas inlet and characterized in that to configure the exhaust gas outlet for discharging the entered exhaust gas at the same time.

본 고안은 측정센서가 외부 대기의 영향을 크게 받지 않고 배기가스의 배출진행이 측정센서로 인해 방해를 받지 않도록 내부가 비어 있는 원통모양의 배기관(1)을 중심으로 소형엔진의 연소실로부터 나오는 배기가스가 통과하는 소형엔진 배기가스 진입로(5)와, 배기관(1)에서 온도센서 연결부(2)내의 센서와 접촉한 배기가스가 소형엔진 배기가스 진입로(5)와 일치하는 방향의 외부대기로 배출되는 배기가스 배출구(4)로 구성이 되며 센서교체를 위한 좌우의 온도센서 연결부(2)와 공연비 센서 연결부(3)로 구성이 된다.The present invention focuses on the exhaust gas from the combustion chamber of a small engine centered on a cylindrical exhaust pipe (1) that is empty inside so that the measuring sensor is not greatly influenced by the external atmosphere and the exhaust gas is not disturbed by the measuring sensor. Exhaust gas coming into contact with the sensor in the temperature sensor connection part 2 in the small engine exhaust gas inlet 5 through which the gas is passed is discharged to the outside atmosphere in a direction coinciding with the small engine exhaust gas inlet 5.

이러한 본 고안은 소형엔진의 배기가스를 측정함에 있어 소형엔진에 맞게 소형엔진 배기가스 진입로(5)를 설치하는 것이다.The present invention is to install a small engine exhaust gas inlet (5) to fit the small engine in measuring the exhaust gas of the small engine.
