Definitions

  • This invention is related with a modular exhaust outlet pipe which enables discharging the exhaust gas flow of internal combustion engines on heavy commercial vehicles, which is fixed at a preferred distance to the exhaust outlet, and enables discharging of the exhaust gas by cooling it with air or by distribution.
  • the exhaust system enables discharging the combustion gas of internal combustion engines.
  • the waste gases that arise as a result of combustion are discharged by means of the exhaust manifold, exhaust pipe and the silencer.
  • the emission value and temperature of the gas discharged out of the exhaust system is very important.
  • Filtering systems have been used to reduce CO, HC and NOx emissions that are produced as a result of combustion in the engine.
  • Exhaust emission values are reduced by means of employing various devices and subsystems such as particle filters and catalytic convertors in the exhaust system.
  • thermodynamic data of engines increase together with the increase in engine volumes, and on the other hand the power and rotation torque expected from the engine also increases. New generation vehicles have higher power and rotational torques, and therefore their exhaust temperatures also increase.
  • the exhaust gas also reaches high temperatures when the engine is running at high efficiency and power.
  • the high temperature of the exhaust gas discharged from the vehicle to the atmosphere may damage the vehicle components, the objects around and they may even cause a fire.
  • the exhaust gas may leave the exhaust system at approximately 500-550 °C depending on the operating conditions of the engine.
  • the sub-components of the exhaust system which has high thermal inertia (filter, catalyst etc.) prevents rapid cooling of the exhaust gas.
  • the exhaust gas is discharged by means of the exhaust pipe only. High exhaust gas temperature and high exhaust gas discharge rate damages both the environment, the materials in the surrounding environment and the components on the vehicle. Before the exhaust gas is discharged to the atmosphere, the exhaust emission must be reduced to a level determined according to the legal regulations.
  • the exhaust filtering system is required to operate efficiently at high temperatures. Dropping of the temperature in the filtering system may result in a decrease in the performance of the filtering elements. Operating of the filtering system at high temperatures is ensured with insulation and design improvements. However, while the exhaust gas leaves the system at high temperatures, it damages the vehicle components, the environment, and it may result in burning of flammable substances such as grass and sawdust in the area where the exhaust outlet is located; in the meantime, it results in burning and damaging of the parts near the exhaust system in the car. The mentioned problems caused by high exhaust gas discharge temperature are experienced in most of the motor vehicles which fulfill low emission objectives.
  • a simple, modular exhaust system has been developed with the subject patent of the application which can easily be applied to different types of vehicles.
  • the subject patent of the application does not affect the layout of oversensitive pieces on the exhaust side, the hot temperature is cooled down and discharged to the atmosphere; damaging of the components where the system is located and rising of dust is prevented.
  • the exhaust gas to be discharged to the atmosphere can be mixed with air and it can be cooled down without being discharged to the external environment.
  • a major technical problem experienced in current practices is the breaking of the exhaust pipe due to reasons such as impact. Since the exhaust outlet pipe is connected to many components, even the components to which the exhaust outlet pipe is connected are required to be replaced together with the pipe. Since the exhaust pipe is not directly connected to the exhaust system in the patent application herein, only replacing the exhaust pipe will be possible if the exhaust pipe is broken. As a result, it provides an improvement in service duration and service costs.
  • the noise problem may also be caused by the exhaust pipe.
  • the exhaust pipe is turned into a modular, easily replaceable structure.
  • the driver can choose a different type of exhaust pipe according to the structure of the vehicle and replace the exhaust pipe easily.
  • the European patent document EP0526673 in the prior art describes an exhaust muffler.
  • the mentioned document mentions discharge of the exhaust gas with air by providing extra air intake through the clearances provided at the exhaust outlet.
  • the US patent document US8272210 describes a tail pipe exhaust cooling device. The device described in the mentioned document is attached to the exhaust pipe. The exhaust gas is cooled by means of the holes on the tail pipe.
  • the International patent document WO2015110057 describes a tail pipe apparatus which is installed into the inner side of the exhaust and which locked by means of multiple self-locking clamps.
  • the patent application herein is related to a modular exhaust outlet pipe which can be positioned at a preferred distance to the exhaust outlet, in such a way that it does not contact the exhaust outlet.
  • the subject exhaust pipe of the application is not directly connected to the exhaust system and the exhaust outlet. It is positioned in such that there will be a gap between the exhaust outlet and the modular outlet pipe.
  • the exhaust gas is blended with air and cooled, and then it is discharged through the exhaust pipe.
  • the modular exhaust outlet pipe is not directly connected to the exhaust discharge, it can easily be replaced and reached.
  • the exhaust gas can be cooled by the modular exhaust outlet pipe and discharged to any desired direction.
  • the exhaust gas can also be distributed and redirected easily by means of a router in the modular exhaust outlet pipe.
  • the objective of this invention is to provide a modular exhaust outlet pipe which enables mixing the air in the environment with the hot exhaust gas flow before the gas reaches the exhaust outlet pipe, thus cooling the exhaust gas and discharging it from the discharge pipe.
  • Another objective of the invention is to provide a modular exhaust outlet pipe which is not connected directly to the outlet of the exhaust gas, and which can be fixed such that it does not contact the exhaust outlet.
  • Another objective of this invention is to provide a modular exhaust outlet pipe, whose angle of repose and the relative distance relative to the exhaust outlet can be changed.
  • Another objective of this invention is to provide a modular exhaust outlet pipe which is produced independent from the exhaust system, and thus which can easily be maintained and replaced.
  • Another objective of this invention is to provide a modular exhaust outlet pipe which can be applied on different types of heavy commercial vehicles, which has a small footprint and which enables easy packing.
  • the modular exhaust outlet pipe defined in the first claim and other dependent claims to provide the objective of this invention is positioned on the outlet of the exhaust system, preferably on the vehicle's chassis such that it will not contact the exhaust system and the outlet.
  • the modular exhaust outlet can be positioned at a preferred angle and at a distance to the exhaust system with an exhaust outlet fixing bracket. There is a gap between the modular exhaust outlet and the exhaust system, and this gap enables mixing the air in the external environment with the hot exhaust discharge. After the hot exhaust discharge mixes with air and it is cooled down for some time, it passes through the modular exhaust outlet and it is discharged.
  • the position and angle of the fixing bracket can be changed and they can be adjusted such that the distance and angle between the exhaust outlet and the modular exhaust outlet pipe remains productive with minimum noise.
  • the modular exhaust outlet pipe can easily be replaced as it is not attached to the exhaust system.
  • the modular exhaust outlet pipe can easily be replaced in the event of a failure such as breaking and wearing out.
