Why the Engine of the Car Shakes When Turned On

When you turn on your car, the engine typically starts up and idles for a few seconds before gradually accelerating. Why does the engine shake like that? It’s all because of the inertia of the mass (the car) relative to the forces acting on it (the engine).

Inertia is what causes objects to keep moving in the same direction even if they’re not being pushed or pulled by an external force. The more mass an object has, the more inertia it has.

What Causes a Car Shakes When Turned On

When a car is turned on, the engine usually starts up and runs smoothly. However, there are a few cases where the engine can shake or vibrate when turned on. This is due to different factors, such as damaged parts or incorrect fuel mixture.

If the engine shake is caused by damaged parts, it can usually be fixed by replacing the part. If the shake is caused by incorrect fuel mixture, however, it may be more difficult to fix. The best way to determine if this is the case is to check for fuel leaks and correct any problems that are found.

How to Fix It

There are a few things that can cause the engine to shake when turned on, and they can all be fixed with a little common sense. Here are four of the most common causes:

1. Dirty Air Filter: One of the first things you should do if you notice your car shaking when you turn it on is to check the air filter. If it’s dirty, it’ll cause the engine to work harder to push air through the filter and into the engine. Simply take off the air filter cover, clean it with a vacuum cleaner and some compressed air, then replace it.

2. Faulty Wiring: If your car’s wiring seems loose or if there are any exposed wires, chances are high that interference is causing the engine to shake. Try tightening up any wiring that’s visible or replacing any worn or faulty parts.

3. Bad Engine Gasket: A bad engine gasket can also cause your car to shake when you turn it on. This happens when oil leaks onto the spark plugs, which in turn causes them to ignite prematurely and send sparks flying through the engine. Replace your engine gasket if it starts making noises or if you see oil leaking from around the spark plugs.

Possible Causes of the Engine Shakes

Possible causes of the engine shaking when turned on may include loose or broken parts that are rattling, worn or defective engine mounts, or a faulty engine control module.
