1. The engine does not have a normal recovery temperature. The reaction is that when the engine is cold started, the temperature is relatively low at this time, and the oil in the engine, because of the long parking time, all flows back to the inside of the oil sall, so this phenomenon occurs.
2. This is because when the cold car starts, the automatic air valve closes, the mixed gas is thickened (conducive to starting), the idle speed is increased, and the sound becomes louder. Secondly, the lubrication system has just started to work, and the parts that need to be lubricated have not been fully lubricated, which also leads to loud noise. A moment after starting, the air valve opens, the idling speed drops, and the lubrication is positive Chang, the voice is quieter.
3. Only when the engine speed is high can it warm up quickly. Many cars will make a loud noise when they first start, and after one time, the sound will gradually become smaller, because the car starts when it is cold. The engine speed is too high, so it will produce a relatively loud noise.
1. The loud cold start noise is due to the fact that the engine has not been fully lubricated at this time. After the engine is fully lubricated and reaches the normal working temperature, the noise of the engine will be much smaller.
2. The loud cold start noise is caused by the fact that the engine is not fully lubricated at this time. After the engine is fully lubricated and reaches the normal working temperature, the noise of the engine will be much smaller.
3. The reason for the "da-da" sound when the cold car starts Hydraulic support: due to the low oil pressure or the wear of the hydraulic support itself, air enters the hydraulic support, resulting in a "da-da" sound. VALVE GAP: THE VALVE ROCKER ARM IS WORN, RESULTING IN TOO LARGE VALVE GAP.
4. The most likely time to happen is when the engine is hot, or cold, or when there is a shortage of oil.The reasons for this kind of problem can be divided into air filter, spark plug, ignition line, gasoline, gasoline filter, gasifier, oil pump and other problems.
5. The cold start noise is very loud, because the engine is not fully lubricated. After the engine is fully lubricated and reaches the normal working temperature, the engine noise will be much smaller. During cold start, the engine oil is in the oil sup shell, with high viscosity and poor fluidity, resulting in insufficient engine lubrication. 99% of engine wear occurs at the cold start time.
1. As for others, it may be internal problems in the engine, such as EGR valve blockage. 3. The engine has a hissing sound, with steam or airIt's like coming out of the engine. Generally, after hearing this sound, the engine will quickly lose power. There may be a problem. The engine is overheated. Check the cooling system.
2. The reasons are as follows: it is not lubricated enough when the cold car starts, and the hydraulic column and mechanical rocker arm do not work properly, resulting in a rattling sound. The condition of the oil is not right: if the viscosity of the oil is too high or too low, the engine will make noise. The belt is not elastic enough: the engine makes a squeaky sound at work.
3. The reason why the car starts loudly may be that too much oil increases the stirring resistance of the crankshaft connecting rod, and the noise will also increase. If there is too much engine oil, the oil will cause unnecessary resistance to the rotation of the crankshaft, resulting in loud noise when the car starts, which will also affect the power output and increase fuel consumption. Other reasons: the machine foot glue is aging or loose.
4. It is caused by the carbon accumulation of the engine. Because the old engine oil is getting thinner and thinner, the carbon accumulates more and more. When the oil is thin, it is easy to spee the oil, resulting in more and more carbon accumulation and loss of a lot of power. When replacing with new oil, the engine cannot adapt to the viscosity of the oil, which may increase the speed, resulting in loud engine noise.
