What Causes Increased Engine Noise and Shaking?
1 Answers
The most common cause of car shaking is a dirty throttle body or excessive carbon buildup in the fuel injectors. When there is too much carbon buildup inside the engine, the gasoline sprayed by the cold-start injector can be largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts. This makes starting difficult, and the combustible mixture in the engine fluctuates between lean and rich, leading to rough idling after a cold start. If necessary, an engine protector can be added to safeguard the engine. Below is an introduction to engine protectors: 1. Overview of Engine Protectors: Engine protectors, also known as engine anti-wear protectors, are additives that effectively reduce wear and corrosion on engine components, inhibit the formation of deposits such as sludge and varnish, and form a protective layer on metal surfaces with high compressive strength and excellent wear resistance. They prevent oil oxidation, thickening, and acidification, thereby protecting engine components and extending engine life. 2. Functions of Engine Protectors: The roles of engine protectors include anti-wear, lubrication, noise reduction, improving engine power, and fuel savings. Some also prevent oil burning and have carbon-cleaning capabilities.
