A blower 5 is connected to the side of the connecting plate 3 near the intake pipe 23. The catalytic converter 22 operates effectively only at high temperatures. By rapidly increasing the catalyst temperature, it can reach its optimal operating conditions sooner, thereby more effectively converting harmful substances in the exhaust (such as NOx, carbon monoxide, and unburned hydrocarbons), reducing pollutant emissions. During cold starts, the engine typically consumes more fuel. If the catalyst reaches an operating state more quickly, the engine can enter a high-efficiency operating range more quickly, thereby improving overall fuel economy and reducing fuel consumption.
