When you accelerate your car, the engine will sometimes shake slightly. This is due to the pistons and valves moving up and down, which makes a knocking noise. There are a few possible causes of this shaking, and they can be sorted into three categories: bad bearings, worn or faulty valves, or incorrect air-fuel ratios. If you’re experiencing this issue with your car, there’s probably an easy fix for it.
What Causes a Car Engine to Shudder When Accelerated?
There are a few potential causes for a car engine to shudder when accelerated. The most common culprit is warped pistons. When the pistons hit the cylinder walls, they create a vibration that travels up the engine and is felt as a shaking or rattling. In severe cases, this vibration can cause the engine to break down. Another common cause of shuddering is worn out bearings. These components allow the engine to rotate smoothly, but if they become too worn, they can start making noise and causing vibration. Finally, fuel injection problems can also cause an engine to shake during acceleration. If there’s not enough fuel getting to the engines cylinders, they won’t be able to get off the ground quickly enough and will vibrate in response.
Solutions to Stop the Shuddering
There are many reasons why your car engine may shudder when you accelerate, but most can be corrected with a simple adjustment. Here are some of the most common causes and solutions:
Piston slap – This is caused by the piston going from a fully retracted position to an active combustion stroke quickly. To remedy the issue, you can adjust the timing or spark plugs.
Oil leak – If there is an oil leak from your engine, it will cause the engine to shake because of the vibration caused by the escaping oil. To fix this, you’ll need to find and fix the leak, and then add lubricant to your engine.
Camshaft timing – If your camshafts are incorrectly timed, this can cause your engine to shudder when you accelerate. To correct this, you’ll need to adjust the camshafts using a service manual or tuner.
Conclusion
It can be difficult to pinpoint the cause of your car engine shaking when you accelerate, but there are a few things you can check to rule out the most common ones. First, make sure your tires are inflated to the correct pressure. Second, make sure there is no debris or dirt caught in your car’s gearingbox or transmission. Finally, if your engine is an automatic one and has a “clutch pedal”, make sure it’s depressed fully before accelerating. If none of these solutions work and you know for certain that your engine isn’t faulty, then you may need to take it into a mechanic for a more thorough inspection.
