How to Solve Incomplete Combustion in Motorcycles?
2 Answers
It is an important component in the intake system of a horizontal four-stroke engine, whose function is to filter out dust, debris, and moisture, reducing the wear of moving parts in the cylinder. Fuel and air are mixed in a certain proportion to form a combustible mixture, and the carburetor controls the flow of the mixture entering the cylinder to regulate the engine's output power. The role of the ignition system is to convert the battery output into high voltage within a limited time according to the engine's working requirements.
Over the years of riding motorcycles, I've noticed that incomplete combustion is particularly common in older bikes. The most obvious signs are black smoke from the exhaust and a sputtering sound from the engine. First, check if the air filter is clogged - last year when I cleaned mine, it was full of dust and dead insects. Then focus on the fuel system; carburetors tend to accumulate gum deposits, so I use specialized cleaner every 5,000 kilometers. Spark plugs are another critical point - once I found the electrode gap was too wide when I took one apart, and replacing it solved the problem immediately. A dirty oxygen sensor can also cause trouble; just clean it with alcohol swabs. Don't forget to check the ignition coils and high-tension wires - my neighbor's bike burned oil because of this. If all these checks don't help, it's likely a cylinder sealing issue requiring engine disassembly to replace piston rings. Using fuel from reputable gas stations can help prevent these problems.
