Jeep Exhaust System

The human body has an excretory system to dispose the toxic materials that can pollute the different parts making up the entire systems. The same purpose is done by Jeep exhaust system. Exhaust systems are made up of components that assist the movement of waste materials from the car's engine to the tailpipe for disposal in the environment. Jeep models which include Wrangler, Liberty and Grand Cherokee are equipped with the newest high-performance dual exhaust system or cat-back exhaust system.

Dual Exhaust systems are made up of piping and one or two mufflers and tailpipes. It provides better breathing capacity by providing easier flow of materials and thus reduces pressure, increases torque and improves the performance of the vehicle. With much better breathing capacity, more exhaust gas are disposed with more space left for an extra air and fuel mixture. Each part making up the jeep's exhaust system plays a vital role in carrying out the function of the whole system. The tailpipe, muffler, catalytic converter, EGR and PCV valves, air pump, exhaust manifold, header, exhaust pipe gaskets and exhaust pipe hangers are just a few of the components included in the system.

Tailpipes or exhaust tips are the visible part of the exhaust system usually located at the rear area under the car's body. It is where the car's exhaust is disposed out into the atmosphere. Mufflers are used to muffle or tone down the noise produced by the exhaust gas due to extremely high pressure. It is made up of tubes, metal holes and plates to diffuse the impact of sound as it go out of the tail pipe. Two types of muffler design are commonly used. The first type pushes the gas into a straight perforated pipe covered with metal or fiberglass to reduce backpressure and tone down the sound. The second type has several baffled chambers to accomplish the same purpose. Catalytic converters are used to purify the harmful gases that negatively affect the environment as it goes out of the jeep's system. The pollutants produced from the imperfect combustion of air and fuel mixture are converted from harmful to harmless through a chemical reaction that occurs as the gas passes into the car's catalytic converter.

The EGR valve or Exhaust Gas Recirculation is utilized to send back or re-circulate the exhaust gas, specifically the harmful Nitrous oxides, into the cylinders to lower combustion temperature and thereby decreasing the amount of Nitrous oxides produced. This pollutant is the major component of smog. The PCV valve on the other hand or Positive Crankcase Ventilation system functions as the old "dump tube" which removes combustion gases and vapors that may get stuck in the piston rings and crankcase that can cause rust, corrosion and bogs.

    The Jeep exhaust system is designed to carry the emissions produced by the combustion process away from the engine in a smooth and efficient flow, helping to maintain the performance and power of the engine. The engine produces a number of waste products during its operation. Among these are several chemicals that are harmful to the environment and humans, contributing to smog and acid rain, and intense waves of sound, generated by engine combustion. These sound waves and chemical emissions would produce unacceptable levels of air and noise pollution if allowed to pass freely from the vehicle. The Jeep exhaust system processes these pollutants as they pass through its chain of components, reducing the concentration of hazardous chemicals and quieting the noise of combustion. The hot exhaust gasses and the sound waves from engine combustion are collected by the Jeep exhaust manifold as they are expelled by the exhaust cylinders of the engine, then are directed through the exhaust pipes to the catalytic converter. The catalytic converter is the component that reduces the toxic chemicals released by the vehicle, using a ceramic honeycomb style structure that is coated with several catalyst metals to create a chemical reaction with their molecules, causing some to burn and others to become trapped. Once the vehicle emissions have emerged from the catalytic converter with the chemical content significantly reduced, they are directed through the system to the muffler, which is in charge of controlling the noise.
