Initially, the main function is to muffle the sound of the
mufflers of the disposal process of waste gas in a car engine. Due to the absence of mufflers, the car's engine will sound very annoying.
Resonator is basically a tube that magnifies the resonance amplitude of a wave at a particular frequency. (Remember the guitar resonator tube, the tube is to strengthen the amplitude of sound generated string)
In essence, motor vehicle exhaust gas flow is not a stable airflow. But a pressure that occur every step of the engine exhaust. Thus, the frequency of these pressures is to exhaust the number of steps taken within a period of engine (RPM).
the engine, the exhaust manifold resonator magnifies the exhaust gas pressure at a certain frequency. Where the frequency is obtained from the engine RPM. Furthermore, when the exhaust manifold pressure increases, the pressure of the combustion chamber when the exhaust step also increases. Pressure is commonly called a kick behind. So that the compression pressure becomes higher and higher power output for low rpm.
Removing the resonator on the exhaust causing the loss of torque at low rpm. But his run at top RPM will be very fierce. In addition, the voice could be noisy.
This part is called body
mufflers, inside there are many pipes and plate that regulates the exhaust flow. Existing pipe inside called the inner pipe mufflers, while the plates are in the muffler body called a separator or separator sections. On the tip of there tail plate body mufflers, or tail end. Tail plate is the deadline for body mufflers and exhaust gas
Additional: resonator is also often applied to the intake manifold. The result, on the intake air pressure can be increased at certain RPM and power increased significantly. Examples of the RX-king with yeis tube. That is just the bike, what if made on the car ....?
Mufflers usually become a forgotten part of her treatment, although it should mufflers became one of the main part of caring for our vehicles. For example, because of the location under the mufflers will be quickly soiled and potentially rusty. Although already coated with anti-rust paint, but we should still take care of and cleaned daily.
In general there are two types of catalytic converter is used, which is a type of pellet and monolithic. Kind of a monolithic catalytic converter that is widely used today. The reason, these types of exhaust gas has a small resistance, lighter, and faster than the type of pellet heat. To reduce the pollutant gases, catalytic converters use some raw materials. Based on raw materials used, the catalytic converter can be divided into two models, namely oxidation catalyst (OC) and the three way catalyst (TWC).
Type of OC use platinum and palladium material, which can reduce CO and HC. While TWC containing platinum and rhodium are able to reduce CO, HC, and NOx. (Matabumi) If without a catalyst converter, the exhaust gas expands out of the mufflers and the sound is much faster than using the catalyst converter
mufflers. Several types of engines with catalyst converter as a guide you in selecting vehicles include: Honda Vario, Honda Beat and Honda MegaPro.
Catalytic converter is one of the biggest innovations in the automotive industry. The reason these devices can change from burning substances such as hydrocarbons (HC), carbon oxide (CO), and NOx, into substances that are more environmentally friendly. Based on data from manufactures of Emission Controls Association (MECA), the United States since the 1970s until today, catalytic converters have helped reduce pollutants as much as 1.5 billion tons in the United States and 3 billion tons worldwide. Forms of catalytic converters like tube shaped like a honeycomb. The material is made of ceramic filters with hole sizes between 1 to 2 mm.
Mufflers or exhaust Indonesian language is an integral part of a vehicle, whether car or motorcycle. An exhaust muffler system in a vehicle engine, designed to mitigate or reduce emissions and noise out of the engine. Because it serves as a flue gas engines, it is usually placed behind the mufflers.
