Blow by is a phenomenon that can occur in car engines when the air-fuel mixture in the cylinders is not evenly combusted. The result is an excessive amount of exhaust gas being released, which can cause the engine to run poorly and even stall. In this article, we will discuss the causes and effects of blow by, as well as some ways to prevent it from happening.
What is Blow By?
Blow By is the term used to describe the phenomenon of air being blown by the engine in a vehicle. It is caused by the engine’s rotating speed and can be a hazardous condition for both the vehicle and its occupants.
Blow By is most commonly seen in cars with small engines, as they produce more air flow than larger engines. The air flow over the engine’s pistons and around its combustion chamber creates a pressure difference that causes air to be blasted out of the system. Blow By can cause damage to both the engine and vehicle components, so it is important to understand how it works and what precautions you need to take if you experience it.
There are a few things you can do to minimize the risk of blow by:
-Make sure your car has enough clearance around its engine; if it’s close together, the faster rotational speed will cause more blow by.
-Choose a small engine if possible; these generate less air flow and are therefore less likely to create blow by.
-Consider getting a car with a turbocharged or supercharged design; these engines produce more power but use less fuel.
Causes of Blow By
Blow by is a problem that can affect the performance of your car engine. There are many causes, but the most common ones are: 1) A worn or defective valvetrain or cylinder head 2) Faulty spark plugs 3) Damaged air filter 4) Defective fuel injection system 5) Wheel alignment issues 6) Exhaust leaks 7) Inefficient ignition system 8) Computer problems
Blow by is a problem that can affect the performance of your car engine. There are many causes, but the most common ones are:
1) A worn or defective valvetrain or cylinder head. This is usually caused by incorrect use or abuse, over-torqueing, or inadequate lubrication. Diagnosing and correcting this issue can often restore lost performance.
2) Faulty spark plugs. These can be damaged by corrosive gases and debris generated from the combustion process, which will cause intermittent firing and poor engine performance. Replacing them with fresh plugs can often fix the problem.
3) Damaged air filter. Over time, dirty air filters will become clogged with dust, dirt, and other particles, which will reduce airflow and cause reduced engine performance.
How to Fix Blow By
Blow by is a common issue with cars and engines. It’s when the air/fuel mixture in the cylinders isn’t burning properly, resulting in a “blowing” or “puffing” noise.
There are three main causes of blow by:
1. Poor air/fuel mixture – This is usually caused by a dirty air filter or dirty fuel injectors.
2. Inefficient combustion – This can be caused by a bad design or faulty engine parts.
3. Fuel starvation – This happens when the car isn’t getting enough fuel to the engine, typically due to low gas mileage or a broken fuel line.
If you’re experiencing blow by, there are several things you can do to fix it:
1. Check your air filter – Dirty filters cause poor air/fuel mixture, which leads to blowby. Replace your air filter every 6 months or 3,000 miles, whichever comes first.
2. Clean your fuel injectors – Inefficient combustion is often caused by clogged fuel injectors. Use an injector cleaner or carburetor cleaner to clean them up and improve performance.
3. Replace faulty engine parts.
Conclusion
Blow by is a phenomenon that often occurs in car engines. It’s when the air intake valve on the engine opens and then quickly closes again, causing exhaust gas to be drawn into the engine. This causes high levels of heat to be generated, which can damage components inside the engine. Blow by should only occur during acceleration or deceleration — not while the car is cruising at a steady speed. If you notice your car blowing by more than normal, it might be time to have your engine inspected.
