Do you want to know ‘how to check if an engine is working after repairs’? To be sure of the repair you made, you need to check that the following systems are working:
- Ignition system
- Fuel supply system
- Air suplly system
- Mechanical structure system
- Sensor system
- ECU system
I have made it a habit to inspect the aforementioned systems to make sure my fixes are satisfactory. There was a point after my overhauling when I checked and found the compression to be really poor.
Please continue on if you’d like me to share my experience with you.
How To Know If Engine Is Working Well After Repair
We often find the car’s engine abnormal when we repair the engine. Still, the self-diagnosis system does not report any fault codes and information, which causes a lot of trouble for the fault judgment of the engine.
First of all, on the premise that the vehicle power system is faulty, our thinking should be considered the following aspects:
1. Ignition system; Check whether the spark plug is normal (the gap and usage of the spark plug). Secondly, check the resistance value of the cylinder line and the distributor, the working condition and conduction of the distributor, and check whether the ignition coil is hot and whether the igniter is hot
2. Fuel supply system: check the oil pressure, oil pump, filter, oil return valve, and fuel injector;
3. Air supply system: Check whether the vacuum pipe is connected for air leakage or blockage in the intake system.
4. Mechanical structure system: check whether there is a lack of cylinder or insufficient cylinder pressure; if so, check whether the spark plug is tightened, valve timing, timing belt position, valve closure, etc.
5. Sensor System: check whether the engine crankshaft position sensor, camshaft position sensor, speed sensor, throttle valve position sensor, knock sensor, oxygen sensor, water temperature sensor, etc., are installed correctly and whether there is any damage.
6. On-board computer (ECU) system: first check the appearance, then check the wiring, check the power supply and grounding, if necessary, carry out a disassembly inspection, and finally, use the car failure detector to detect the data flow of the engine.
WHAT DOES A HEALTHY ENGINE SOUND LIKE
There are different sounds your engine can produce, but you need to understand each of them and what they signify.
You also need to understand your engine’s normal sound. When your engine is ok, you will hear a sound like ‘Vroom, vroom.’ That is the sound of a healthy engine.
But there are other sounds that you may come across, such as;
- whistle
- clicking
- ticking
- Rumbling
- Ka-ka-ka(noisy turning)
And many others are sounds that show your engine has a fault.
But anytime your engine is sounding “vroom vroom,” you should be rest assured that your engine is ok.
How Does An Engine Make Sound
No matter how strong your engine is, it must only create a very slight noise. You might be wondering, “How does it create sound?”
You must comprehend how your engine functions. All four internal combustion engine strokes—induction, compression, power, and exhaust—are included. Your engine operates according to these four sequences.
There was an explosion that happened during the power stroke. During the power stroke, your injectors atomized compressed air, which led to an explosion.
Based on the firing order arrangement, this explosion occurred on each cylinder at a distinct moment.
That is the explosive sound that often emanates from your engine.
The explosion was so strong that it forced the piston in your engine to go downward.
But it shouldn’t be too loud, the sound should be peaceful and smooth.
In conclusion, sound will undoubtedly be produced by the combustion process and hundreds of metals coming together, but the lubricating system takes care of that.
Why Do Engines Sound Different
The truth is that every engine standard has a unique sound. A Mercedes Benz sounds different than a BMW, and a cat engine sounds different from a Detroit engine.
You must keep in mind that although having a diverse tone, each of these examples was produced in the same nation.
Why are there different sound continue reading
1. Firing Order: The firing order configuration affects how loud your engine sounds. Flat-plan cranks and cross-plan cranks are the two main configurations.
2. The exhaust system: The sound of your engine is determined by how the byproducts of internal combustion exit your exhaust tailpipe.
3. The valve train system: Your engine’s sound is determined by the valves’ lashes and layout.
You can see why different engines have distinct sounds from these factors.
HOW DO YOU CHECK IF YOUR ENGINE IS DAMAGED
These are a few indicators that will let you know if your engine needs repair.
1. Weird Noise: If your engine is making an odd noise. Any unusual noise coming from any component of your engine is a sign that it is damaged.
2. Fluid Leaks: If coolant or lubricant leaks from your engine, it’s a symptom that a component is worn.
3. Unusual Smell: If you detect a burnt or other scent coming from the engine, your engine may have been damaged.
4. Power Loss: Engine damage can be indicated by any indicator of power loss, including a lack of compression.
5. Weak Acceleration: If your accelerator pedal is acting differently than it should, there is a problem.
6. Rough idle: If your engine’s sound is not constant when it is idling, you should be aware that it is malfunctioning.
7. Warning light illuminates: If your warning light illuminates, you should see a repair shop.
8. Hard starting
These are the typical indications that an engine is damaged. Your engine may still be functioning if you notice the aforementioned symptoms, but that shouldn’t stop you from seeing your mechanic.
How Can I Make My Engine Healthy
10 things you can do to maintain the health of your engine
1. Consistently replace the engine oil
2. Pay attention to the cooling system and don’t just use tap water for the coolant
3. Quickly fix any leaks that may exist.
4. Keep an eye on the warning light and promptly clean and replace the air filter.
6. Remember to change your transmission oil.
7.Avoid driving with an empty tank.
8. Develop the habit of maintenance
9. Utilize high-grade fuel
10. While performing maintenance, swap out the oil and fuel filters.
Your engine life will be increased if you can follow these suggestions.
