What are the hazards of engine knocking in cars?
4 Answers
The hazards of engine knocking in cars include: 1. Decreased engine power and increased temperature; 2. Increased load and wear on internal engine components; 3. Increased formation of carbon deposits inside the engine; 4. Deformation of internal engine components due to elevated temperatures. An engine is a machine capable of converting other forms of energy into mechanical energy, suitable for power generation devices, and also refers to the entire machine including the power unit. Types of engines include: internal combustion engines, external combustion engines, and electric motors. Engines can be categorized by working principle into piston engines, ramjet engines, rocket engines, and turbine engines.
I've experienced engine knocking several times, and the most direct damage is its violent impact on pistons and cylinder walls, which can deform metal components or even cause cracks. Over time, it may lead to piston ring seizure and complete engine failure. Once when I was driving on the highway, the engine knocked, causing an instant power drop and a 20% surge in fuel consumption. The repair afterward cost over ten thousand yuan. Not to mention the annoying rattling noise, which also accelerates spark plug aging. So when you hear abnormal sounds, get it checked immediately—don't try to save small money by using lower-grade gasoline.
From a user's perspective, the hazards of engine knocking are that it can destroy the normal operation of the engine. Incomplete combustion leads to unstable power output, making driving feel as strenuous as towing a trailer, and causing difficulties in acceleration and overtaking. Fuel consumption rises sharply, significantly increasing monthly fuel expenses. Safety-wise, it's even more troublesome—in severe cases, the engine may suddenly stall, greatly increasing danger on highways. It also affects emissions, which is bad for the environment. It's recommended to perform regular maintenance, such as cleaning carbon deposits to prevent knocking.
The main hazard of engine knocking is damage to the internal engine components. It can damage pistons and cylinders, reducing power efficiency. Additionally, it causes loud noise and poor driving experience. It is recommended to use appropriate gasoline to mitigate the risk.
