Answer:
The small engine and implement industry has adopted a variety of emission control technologies to reduce pollution from engine and implements. Major innovations include direct fuel injection, spark ignition, catalytic converters, fuel reformulation, and combustion optimization. These technologies reduce the amount of hazardous air pollutants (HAPs) released into the environment. In addition, the industry has implemented stringent pollution control regulations and certification standards to further protect the environment from hazardous emissions. The main reason why the small engine and implement industry has implemented emission control techologies is to meet the requirements of Environmental Protection Agency (EPA) regulations and reduce local air pollution.
