CNG AUTOMOBILE GAS SENSOR MODULE WITH FILTER

摘要

The present invention relates to a filter for a gas sensor module of a CNG vehicle. The filter in a resin type is applied to filtrate impurities in a gas sensor of the gas sensor module of a vehicle. Therefore, the filter can extend the life span of the gas sensor module of the vehicle exposed to pollutants in a large amount, and can maintain reactivity of the gas sensor module to be constant. More specifically, the filter is located on an outer part of the gas sensor module of the vehicle, the module applied to a gas detector which measures the density of at least one of gases including combustible gases and carbon dioxide. The filter (10) is formed in the resin type. Therefore, when applied to a vehicle, the filter can prevent or reduce pollution of the gas sensor in the gas sensor module caused by pollutant such as dust in the air. The filter extends the life span of the gas sensor module and significantly reduces maintenance costs.
