EVAP Smoke Machine: What You Need to Know!

EVAP Smoke Machine: What You Need to Know!

When you own a car, it’s almost impossible for something to not go wrong. Some of these issues that go wrong with your car are a little bit harder to identify than others. Unfortunately, evaporative emissions leaks are difficult to identify.

 

An EVAP smoke machine could be just what you’re looking for. You can test evap and vacuum leaks with this tool, which are usually easy-to-use and come with instructions for information on proper use and set up. We are going to discuss the EVAP basics and construction, how to test for EVAP leaks (focusing on the EVAP smoke machine), and the top EVAP smoke machines for purchase.

 

Why Do Evaporative Emissions Leaks Occur?

 

Whenever you fill up your tank with fuel, the engine runs on the fuel vapors – not the liquid fuel itself. This makes sense, since the fuel evaporates during use. However, the fuel vapors are harmful to the human body, and for the environment as a whole. There are numerous side effects of emissions inhalation, like asthma and lung disease for people, and smog and climate change for the environment. You need to be able to understand the basic EVAP system in order to determine how to properly fix the leak with an EVAP smoke machine.

 

EVAP System Basics

 

The EVAP system consists of tubes connecting various parts of the fueling system, a charcoal canister for activated charcoal, and numerous valves which regulate the air flow and vapor flow into the system. The EVAP system needs to remain sealed to be the most effective.

 

The EVAP system is responsible for preventing your car from releasing toxic vapors from the gasoline. The technician will need to make sure there isn’t an issue anywhere else in the car as well, like the valves and vacuum hoses. Your technician may have to run an EVAP purge system in order to keep your car running efficiently.

 

The EVAP system can sometimes test itself for leaks depending on the specific model. Some systems utilize a vacuum or pressure sensor to detect the issue. Other systems can use a dedicated pump to run a similar test with a similar function.

 

Leaking EVAP System

 

The EVAP system is used to recycle the unused gasoline vapors back into the tank, as we have just gone over. The problem is when this system experiences a malfunction, since it can be tough to diagnose. Sometimes, this issue is signalled by a check engine light. The cost to replace the EVAP cannister alone is $450-$600, and can go higher if hte leak isn’t in an obvious position.

 

 

How To Test For EVAP Leaks

 

When testing for an evaporative emissions leak, the leak can sometimes be localized depending on the specific code. You should check your manual in order to help you figure out where the leak is specifically coming from. However, you need special equipment to look for vacuum leaks, since it can be extremely difficult to sense where the origin is without the required equipment and tools.

 

First, you can do a vacuum test. An engine vacuum gauge can be used to test valves and lines easily and quickly. While the engine is running, check for vacuum in the EVAP system, with the ideal amount being none.

 

Second, you can use a hand vacuum pump. This method can be used to check EVAP system valves. The vacuum gauge can show if the valve is holding the correct amount of pressure, and you can check the power valves on their operating power and sealing.

 

Third, you can use a smoke test. This is the test and method that we will be focusing on in this article. The idea behind the smoke test is relatively simple, since all you have to do is blow smoke into the EVAP system and notice any smoke escaping from a broken appliance, like a valvec, seal, or hose.

 

In regards to testing the EVAP system, smoke testing is regarded as the best way to test. However, it’s one of the most expensive methods of doing this, with professional smoke machines costing upwards of $600.
