Engine Components: Stihl Br 800 Parts Diagram
The Stihl BR 800 backpack blower is powered by a 2-stroke engine that delivers exceptional performance and durability. Understanding the components of this engine is crucial for proper maintenance and repairs.
The engine consists of several key parts that work together to convert fuel into mechanical energy. These components include the cylinder, piston, crankshaft, connecting rod, and spark plug. The cylinder houses the piston, which moves up and down within it, compressing the air-fuel mixture and creating power. The crankshaft converts the reciprocating motion of the piston into rotary motion, which is then transferred to the backpack blower's fan. The connecting rod connects the piston to the crankshaft, facilitating this motion. The spark plug provides the electrical spark that ignites the air-fuel mixture, initiating the combustion process.
Maintaining the engine components of the Stihl BR 800 is essential for its optimal performance and longevity. Regular cleaning and inspection of these parts can help prevent issues and ensure smooth operation. Replacing worn or damaged components promptly is also important to maintain engine efficiency and prevent further problems. By understanding the components of the 2-stroke engine and following proper maintenance procedures, you can keep your Stihl BR 800 backpack blower running at its best.
Cylinder
The cylinder is a cylindrical metal component that forms the combustion chamber of the engine. It houses the piston and provides a sealed environment for the air-fuel mixture to be compressed and ignited. The cylinder is typically made of aluminum or cast iron and is designed to withstand high temperatures and pressures.
Piston
The piston is a cylindrical metal component that moves up and down within the cylinder. It compresses the air-fuel mixture and creates power by transferring the force of combustion to the crankshaft. The piston is typically made of aluminum or cast iron and has a series of rings that seal against the cylinder walls, preventing leakage of the air-fuel mixture.
Crankshaft
The crankshaft is a rotating metal shaft that converts the reciprocating motion of the piston into rotary motion. It is typically made of forged steel and is supported by bearings within the engine case. The crankshaft has a series of cranks that connect to the connecting rod, which in turn connects to the piston.
Connecting Rod
The connecting rod is a metal rod that connects the piston to the crankshaft. It transmits the force of the piston's movement to the crankshaft, causing it to rotate. The connecting rod is typically made of forged steel and is designed to withstand high forces and stresses.
Spark Plug
The spark plug is a small electrical component that provides the electrical spark that ignites the air-fuel mixture in the cylinder. It consists of a central electrode, a ground electrode, and an insulator. The spark plug is typically made of ceramic and is designed to withstand high temperatures and electrical currents.
Fuel System
The fuel system of the Stihl BR 800 is responsible for supplying the engine with the fuel and air mixture it needs to operate. The system consists of a fuel tank, fuel lines, a carburetor, and a fuel filter.
The fuel tank is located on the top of the engine and holds approximately 0.5 liters of fuel. The fuel lines connect the fuel tank to the carburetor, which is responsible for mixing the fuel with air and delivering it to the engine. The fuel filter is located between the fuel tank and the carburetor and helps to remove any impurities from the fuel.
Troubleshooting and Repairing Common Fuel System Issues
If you are experiencing problems with your Stihl BR 800, it is important to check the fuel system for any issues. Common fuel system problems include:
- Clogged fuel filter: A clogged fuel filter can restrict the flow of fuel to the carburetor, causing the engine to run lean and stall. To fix this problem, simply replace the fuel filter.
- Dirty carburetor: A dirty carburetor can cause the engine to run rich or lean, or it may cause the engine to stall. To fix this problem, you will need to clean the carburetor.
- Leaking fuel lines: Leaking fuel lines can cause the engine to run lean and stall. To fix this problem, simply replace the leaking fuel lines.
Air Intake and Exhaust System
The air intake and exhaust system of the Stihl BR 800 blower is responsible for providing the engine with the air it needs to run and expelling the exhaust gases. The system consists of an air filter, carburetor, and muffler.
Air Filter
The air filter is located at the front of the blower and is responsible for removing dust and debris from the air before it enters the carburetor. The air filter should be cleaned or replaced regularly to ensure that the engine is getting the clean air it needs to run properly.
Carburetor
The carburetor is located between the air filter and the engine. It mixes the air and fuel together in the correct proportion to create a combustible mixture. The carburetor should be adjusted periodically to ensure that the engine is running at its best.
Muffler, Stihl br 800 parts diagram
The muffler is located at the end of the exhaust system. It reduces the noise level of the blower by directing the exhaust gases through a series of chambers. The muffler should be replaced if it becomes damaged or clogged.
Electrical System
The Stihl BR 800's electrical system is responsible for providing the spark that ignites the air-fuel mixture in the engine. It consists of an ignition coil, spark plug, and wiring harness.
The ignition coil is a transformer that converts the low-voltage current from the battery into a high-voltage current that is necessary to create a spark. The spark plug is a device that creates the spark by allowing the high-voltage current to jump across a gap between two electrodes.
Troubleshooting and Repairing Electrical System Issues
Common electrical system issues include:
- No spark
- Weak spark
- Intermittent spark
No spark can be caused by a faulty ignition coil, spark plug, or wiring harness. A weak spark can be caused by a dirty or worn spark plug, or a weak ignition coil. An intermittent spark can be caused by a loose connection in the wiring harness.
To troubleshoot electrical system issues, start by checking the spark plug. If the spark plug is dirty or worn, replace it. If the spark plug is good, check the ignition coil. If the ignition coil is faulty, replace it. If the ignition coil is good, check the wiring harness for loose connections.
