Why Does the Engine Get Damaged?

[DeLawson]

Engine damage can occur due to the following reasons: 1. Deterioration of engine oil and clogged oil filter—after a certain mileage, the performance of the oil degrades, potentially causing engine issues; 2. Blocked air filter—it's essential to clean the air filter regularly, such as using high-pressure air to blow out dust from the inside out; 3. Excessive sludge in the crankcase—small amounts of sludge may remain suspended in the oil, but when excessive, it can separate and clog filters and oil passages, making engine lubrication difficult and accelerating wear; 4. Poor maintenance of the fuel system—fuel can form gum and carbon deposits as it travels through the fuel lines to the combustion chamber, accumulating in fuel passages, carburetors, fuel injectors, and the combustion chamber, disrupting fuel flow, altering the air-fuel ratio, and leading to engine knocking, unstable idling, poor acceleration, and other performance issues.
