What is Scavenging of Engine?


What is Scavenging of Engine? || Types, Advantages and Disadvantages:





Scavenging is the process of removing exhaust  gases from the cylinder after combustion and replenishing the cylinder with fresh air. 


In Scavenging process, Exhaust gas is spring out from Exhaust port and fresh air go inside from intake port both process occur at the same time. due to the overlapping of valve or ports at same time in cylinder.so this process is called Scavenging process.

This process is necessary for smooth running of both four-stroke and two-stroke engine.

Scavenging is the process of removing exhaust  gases from the cylinder after combustion and replenishing the cylinder with fresh air. 

This scavenging process, whether it is a 2 stroke engine or a 4 stroke engine, is for smooth running of both.

What does scavenging mean?
  •  to remove (dirt, refuse, etc.) from an area.
  •  to clean away dirt or refuse from : cleanse scavenge a street.
  •  to feed on (carrion or refuse)
  •  to remove (burned gases) from the cylinder of an internal combustion engine after a working stroke.

Types of Scavenging, Advantages and Disadvantages

Types of Scavenging, Advantages and Disadvantages :   Scavenging are generally three types: Uniflow  Scavenging Reverse or Loop Scavenging Cross flow Scavenging Uniflow scavenging: In this, both the fresh air and exhaust gases move towards the equipment in the same direction. therefore it is called as uniflow scavenging. in this the intake port is mounted on the bottom and the exhaust port is mounted on the upper end.fresh air comes from the bottom of the cylinder and pushes the exhaust gas in upward direction. the exhaust gases pass through the exhaust port to the atmosphere. and again the fresh air enters the cylinder from the intake port. this type of scavenging is done in a large two stroke diesel engine. Advantages: From uniflow the power output is increase. it is very efficient as compare to both reverse and cross scavenging. It has the throttle position and the high speed whatever happens which is always scavenging. Disadvantages: It is very costly. It is difficult to cool the e

Overfilling Engine Oil - Symptoms, Consequences and Solution || [मोबिल ज्यादा डालने से क्या होगा?]

Overfilling Engine Oil - Symptoms, Consequences and Solution: Overfilling  the engine  oil  in  your  car can cause serious damage to  your  internal engine parts and eventually lock up  your  engine.  If you add excess oil in your vehicle, the symptoms might not show up all of a sudden. But inside the engine, the crankshaft will be submerged in excess oil. Pouring excess oil into the engine would also invite more air into the engine chamber.  and as the crankshaft rotates at a high-speed, the  oil  is mixed with the air and 'aerates' or becomes foamy. Overfilling your engine oil can cause serious damage to your engine. Some common symptoms are oil leaks from the engine and blue smoke from the exhaust pipe is occur. Here are some of the most common symptoms of oil overfill: Bad Engine Performance Driving your car with too much oil is going to cause the oil to transform into a frothy foam that cannot provide sufficient lubrication to the engine’s moving parts. As a result
