Severe shaking during cold start of Lavida may be caused by carbon deposits, weak ignition, low cylinder pressure, or substandard fuel. The following are the reasons and specific solutions for severe shaking during cold start of Lavida: Reasons for severe shaking during cold start of Lavida: Excessive carbon deposits in the intake tract. Mechanical failures such as ignition coils, spark plugs, and fuel injectors. Excessive carbon deposits in the engine. Specific solutions: Excessive carbon deposits in the intake tract need to be cleaned in time. If the fuel quality is substandard, it is recommended to use standard quality fuel. Low oil pressure or cylinder pressure leads to insufficient power. Mechanical failures such as ignition coils, spark plugs, and fuel injectors cause cylinder misfire, and it is recommended to replace ignition coils, spark plugs, and fuel injectors. Excessive carbon deposits in the engine, as the structure of carbon deposits is similar to a sponge. When carbon deposits form on the valves, part of the fuel injected into the cylinder each time will be adsorbed, making the actual mixture entering the cylinder leaner, leading to poor engine performance, difficulties in cold start, unstable idle, poor acceleration, backfire during sudden acceleration, excessive exhaust emissions, increased fuel consumption, and other abnormal phenomena, resulting in engine shaking during cold start.

How are motor oil types classified by grade?

Motor oil types are classified by grade as follows: 1. AB series: Gasoline and light-duty diesel engine oils; 2. C series: Catalyst-compatible engine oils; 3. E series: Heavy-duty diesel engine oils. The functions of motor oil are: 1. Cooling and temperature reduction; 2. Sealing and leak prevention; 3. Cleaning and purification; 4. Shock absorption and buffering; 5. Lubrication to reduce wear; 6. Rust and corrosion prevention; 7. Component protection. Motor oil, also known as engine lubricating oil, is composed of base oil and additives. Base oil is the main component of lubricating oil, determining its fundamental properties, while additives compensate for and improve any deficiencies in the base oil's performance.
