What Causes Engine Shaking on the Highway?
1 Answers
There are several reasons for engine shaking on the highway: 1. Dirty air filter: The air filter protects the engine from wear and tear. Simply replacing the air filter can resolve the issue. 2. Broken high-voltage wire: A broken high-voltage wire refers to a break in the wire core, which can affect ignition and cause engine shaking. 3. Low idle speed: The engine idle speed is preset in the car's computer. If the RPM drops below a certain range, the car's computer will automatically adjust it. 4. Abnormal water temperature: The engine operates within a normal temperature range. If the water temperature is too high, it can lead to premature ignition timing, changes in the air-fuel mixture, thinning of engine oil viscosity, and reduced lubrication performance. 5. Clogged fuel injector: The fuel injector in an electronic fuel injection vehicle is a critical component for fuel delivery and has a long lifespan, often reaching hundreds of thousands of kilometers. However, deposits in gasoline can clog the injector nozzles, causing uneven fuel delivery among injectors. This results in inconsistent cylinder operation and engine shaking.
