Q&A: Checking the dwell angle
What is the purpose of checking the point gap in an engine?
The point gap is crucial for ensuring proper ignition timing. If the gap is too wide or too narrow, it can lead to poor engine performance and misfiring.
How do you measure the point gap using a feeler gauge?
To measure the point gap, insert a feeler gauge between the points when they are closed. Adjust the gauge until it fits snugly, ensuring it matches the spec provided in the vehicle’s manual.
What should you do if the points are closed and the gap is not within spec?
If the points are closed and the gap is not within spec, you need to loosen the adjusting screw and carefully set the points to achieve the correct gap before tightening the screw again.
How often should you set the dwell on an older vehicle?
You should set the dwell periodically, typically every 10,000 to 15,000 miles, or whenever you notice irregular engine idle or performance issues.
What does it mean when the points open during engine operation?
When the points open, it allows current to flow to the ignition coil, generating a spark. This action is essential for igniting the air-fuel mixture in the engine’s cylinders.
How do you determine the correct spec for setting the points?
The correct spec for setting the points can usually be found in the vehicle’s service manual or repair guide. It will provide specific measurements for both point gap and dwell angle.
What happens if you do not set the points correctly?
If you do not set the points correctly, it can lead to poor ignition timing, resulting in rough idle, decreased fuel efficiency, and potential engine damage over time.
Why is it important to check both the point gap and dwell angle?
Both the point gap and dwell angle are critical for optimal ignition performance. Incorrect settings can cause misfires and affect overall engine idle quality.
Can adjusting the cam affect the point gap?
Yes, adjusting the cam can affect the point gap because it changes how far the points open and close during engine operation. Proper alignment is essential for maintaining correct specifications.
What is the relationship between idle speed and point gap?
The point gap can influence idle speed; if it is not set correctly, it may cause an unstable idle or prevent the engine from idling smoothly. Proper adjustment ensures consistent performance.
What is the purpose of checking dwell in an engine with breaker points?
Checking dwell is essential for ensuring that the ignition coil has enough time to saturate, which affects the average voltage produced for a strong spark.
How do you set the point gap correctly in a 4 cylinder engine?
To set the point gap, use a feeler gauge to measure the gap between the closed points. Adjust the gap with an allen wrench until it matches the manufacturer’s specifications.
What happens when the points are open during engine operation?
When the points are open, the magnetic field collapses, generating a high voltage that triggers the ignition coil to send a spark to the cylinder engine.
How do you adjust the dwell angle for optimal ignition timing?
To adjust the dwell angle, you need to set the gap and then use a dwell meter to measure it while turning the engine over. Make adjustments to the rubbing block or cam lobe as needed.
What is involved in setting points on a GM 8 cylinder engine?
Setting points on a GM 8 cylinder engine involves removing the distributor cap, adjusting the gap between the breaker points, and ensuring that the cam lobe properly opens and closes the points.
How does varying the dwell affect engine performance?
Varying the dwell can change how long the points are closed, which affects coil saturation and can lead to either improved performance or misfiring if not set correctly.
What tools are typically used to get the dwell setting accurate?
An allen wrench is commonly used to make adjustments, along with a feeler gauge to check the gap and a dwell meter to ensure proper angle settings.
Why is it important to check for gap changes over time in breaker points?
Gap changes can occur due to wear on the rubbing block or contact breaker, which can lead to improper ignition timing and affect engine performance if not addressed.
How does removing the distributor impact setting points and dwell?
Removing the distributor allows for easier access to set the point gap and adjust the dwell angle without obstruction from other engine components.
What role does a capacitor play in maintaining dwell settings in electronic ignitions?
In electronic ignitions, a capacitor helps stabilize voltage and smooth out fluctuations, ensuring that the dwell angle remains consistent for optimal ignition performance.
