What Causes Loud Engine Noise While Driving?

[McAiden]

There are several reasons why the engine noise is loud while driving: 1. The engine oil does not meet the standard or is overfilled, increasing the stirring resistance of the crankshaft connecting rod; 2. The oil viscosity is unsuitable; 3. Excessive carbon deposits in the engine, exacerbating wear on the cylinder and piston; 4. Mixing different brands of engine oil; 5. Failing to change the engine oil on time. The function of the engine is to convert the thermal energy of gasoline or diesel into mechanical energy by burning the fuel in a sealed cylinder, causing the gas to expand and push the piston to perform work. Engine maintenance includes: 1. Regularly changing the engine oil and oil filter; 2. Keeping the crankcase well-ventilated; 3. Regularly cleaning the crankcase; 4. Periodically cleaning the fuel system; 5. Regular maintenance of the radiator; 6. Cleaning and maintaining the fuel system.
