Have you ever felt that your car suddenly doesn't have power? Or maybe the car's fuel consumption is more extravagant than usual? This can happen because of the accumulation of carbon deposits from the combustion residue that accumulates in the engine combustion chamber. Then why can there be a buildup of carbon in the combustion chamber?
In general, a weakened compression pressure is caused by a compression leak in the car engine. Due to weak compression, there is a buildup of carbon crust in the engine compartment and further worsens the performance of your car engine. Compression leaks can occur anywhere and usually the engine compression weakens due to a gap or gap in the combustion chamber towards the outside. Therefore, a gap arises in several components of the car engine. What are the components that are prone to gaps that cause the car engine to be less powerful, let's see below.
The first component that causes an underpowered car engine is piston ring wear. The outside of the piston rings will continue to rub against the cylinder walls when the engine is started. This continuous friction will cause very little friction. But over time it will become large and the effect will be felt within 5 years or more if you don't change the oil regularly. Therefore, to reduce friction, never forget to change the car engine oil.
In addition to piston ring components, worn cylinder block components can also cause a car to be underpowered. The cylinder block is the path of movement of the piston rings which will wear out more if there is not enough lubrication in the component. In general, the cylinder block has more strength than the piston rings, but it is possible for the cylinder block to wear out faster than imagined. The cause of the wear of the cylinder block to cause the engine to be powerless is the lack of lubrication in that part. Basically engine oil that will prevent friction between the piston rings and the cylinder block. If the oil is not enough, then the wear of these two components will also occur more quickly and thus make the car less powerful.
Another cause of underpowered cars is a leak in the valve or valve. The valve or valve serves as the entrance of material (air and gasoline) from the intake, and as the exit of exhaust gases from the engine to the exhaust. Currently, many car engines use a double valve (DOHC) system, which means that in one cylinder there are two intake valves and two exhaust valves. This DOHC system will further facilitate the entry and exit of materials to the engine, but if there is an improper valve clearance adjustment, it will lower the engine compression pressure or make the car less powerful.
Another cause of underpowered cars is packing components or gaskets that are torn or aged. The cylinder head packing or gasket functions to close the cylinder block components with the cylinder head which are both made of metal. Without a gasket, there will be a compression leak at this joint. So gaskets or packing play an important role to prevent compression leakage on the lower cylinder block with the upper cylinder block.
Another cause of an underpowered car engine is a cracked or torn spark plug seal component. The spark plug seal will generally be replaced with every spark plug replacement, this seal is already in the package with the spark plug (attached to the spark plug thread) so if you replace the car spark plug, the spark plug seal will automatically be replaced. However, if you replace the spark plugs with other spark plugs that do not match the size recommendations, of course the spark plugs will not work optimally so that the car engine becomes powerless.
