Heating type exhausting silencer of motorcycle

Abstract

The invention belongs to a motorcycle exhaust muffler technique and provides a motorcycle heating exhaust muffler. A heating resistor 4 and a temperature sensor 3 are arranged between an exhaust pipe 5 and a catalytic converter 2. The heating resistor 4 is connected with a storage battery through a protective pipe, an ignition switch, a heater relay and a temperature switch to form a primary heating circuit. The heater relay is a normally-open contact relay. The temperature switch is a normally-closed contact relay. An output terminal A of four terminals of the controller is connected with the heater relay through the temperature switch, a power supply terminal B is connected with a power supply through the ignition switch, a signal terminal C is connected with a trigger coil of a magneto and the magneto, and a grounding terminal E is connected with a negative pole of the storage battery. The device is novel in design and reasonable in structure, and can use the temperature sensor to sense the low-speed running of an engine and send a signal to turn on the primary heating circuit to realize heating of the exhaust muffler, so that the temperature of exhaust is raised to an initiation temperature of the catalytic converter to convert the exhaust quickly.

Description

technical field [0001] The invention belongs to the motorcycle exhaust muffler technology, and mainly proposes a motorcycle heating exhaust muffler. Background technique [0002] At present, in order to meet the new three-stage emission standard (GB14622-2007) promulgated by the National Environmental Protection Agency, a motorcycle must be equipped with a catalytic converter in the exhaust muffler of the motorcycle. Harmless gas; since the catalytic converter needs a certain temperature when it is ignited, the catalytic converter cannot work when the car is cold. As a result, the exhaust gas before ignition cannot be converted, and this part of the exhaust gas is harmful to the air Pollution has a large amount of emissions, so certain measures must be taken to control it. Contents of the invention [0003] The object of the present invention is to provide a heated exhaust device for a motorcycle, so that the catalytic converter in the exhaust device of the motorcycle can...
