摘 要:摩托车污染物主要包括HC、CO、NOx、CO2。其中CO2虽然对人体无毒无害,但由于它是温室气体的主要成份,世界各国也在严格控制其排放。目前我国的摩托车按照燃油供给方式分为化油器式和电喷式两种。化油器摩托车由于技术成熟、成本低廉,配合三元催化转化器及二次补气等机外净化技术也可以满足我国当前的排放控制法规,因此,仍然为广大摩托车生产企业所采用。但随着摩托车排放法规的日益加严,化油器摩托车由于无法满足排放法规将逐渐被淘汰,取而代之的电喷摩托车将成为主流。Pollutants from motorcycles mainly are HC, CO, NOx, C02. Although CO2 have no harm to human body, it is the main component of greenhouse gases and strictly controlled by most of the countries in the world. At present motorcycles in our country are divided into carburetor type and EFI type according to the fuel supply methods. Since carburetors have the advantages of mature technology and affordable price, and with outer purifier means such as three-way catalyst and the secondary air etc, motorcycles can meet China~ current emissions control regulations for motorcycles, carburetors have long been widely used in motorcycles. But with emissions control regulations for motorcycles increasingly being tightened, most of carburetor motorcycles can't meet the new emissions control regulations for motorcycles and will gradually be replaced by EFI motorcycles.
