What is engine knock?
Engine knocking means a metallic sound when pressing the accelerator pedal. The sound can be hollow, tapping, or even rattling. But either way You want your engine to run smoothly and make less noise.
What are the disadvantages of engine knocking?
Engine knocking can cause many emissions problems, such as the release of nitrogen oxides and unburned hydrocarbons. It is a toxic gas that can cause asthma and emphysema. Therefore, you need to be aware of some facts about engine knocking to keep your environment and vehicle safe.
Causes of engine knocking
- One of the main reasons for engine knocking can be improper combustion of the air-fuel mixture. This is the result of early combustion. This is due to the accumulation of carbon in the combustion chamber. Insufficient air/fuel mixture And if the ignition occurs too quickly.
- Engine knocking can be caused by the engine overheating. Which again is a combustion problem.
- Wear of the pistons or valves can cause engine knocking.
- Lack of lubrication also causes the engine to knock out most of the time.
- Lack of exhaust gas flow causes engine knocking. which is a problem with the cooling system
- And overheating of the exhaust valves due to weakened valve springs or bad seats also results in engine knocking.
- Damage in the crankshaft bearings, a broken flywheel that connects the engine to the transmission, overused water pump bearings, loose timing belts, faulty air conditioning compressors. or an alternator with overloaded bearings This may result in the engine knocking instead of the internal mechanism. Defects that can cause the engine to produce that knocking sound.
- Engine knocking also results in regular use of poor quality fuel. This is usually a lower-octane fuel that ignites at a lower temperature. Low enough to be ignited by the internal temperature of the engine cylinder. Engine with high compression Carbon build-up on the cylinder head heats up and behaves like a spark plug. This ignites the fuel randomly.
Engine knocking cannot be easily identified. And it is necessary to have knowledge, if not enough, about the car's techniques to solve the problem. And when you identify the problem Not really necessary For you to remove the entire engine Instead of trying to find the cause of the knocking and trying to fix it without actually removing the engine. There are some simple maintenance tips to make sure your bike engine doesn't fail too often. Check and clean spark plugs Warm up the engine for a moment before running. And finally, clean the engine once a year. Additionally, when you give your motorcycle an engine tune-up, Check with your mechanic and make sure it has not been overtuned to a high compression ratio. Check with the motorcycle manufacturer and use only the specified fuel and engine oil.
