As you know, installing gas equipment is practically the only way to reduce fuel costs in the case of gasoline cars. The main advantage is the more affordable price of gas compared to gasoline or diesel fuel.
However, even taking into account the fact that gas equipment is a reliable and trusted solution, and is constantly being improved by the manufacturers themselves, the possibility of various problems should not be ruled out.
The result is unstable engine operation; the driver notes that the engine is running rough on gas, although the unit can operate normally on gasoline. Also, quite often, along with tripping, gas consumption increases, throttle response and traction disappear. In some cases, a “check” may light up on the dashboard. Next, we will look at common reasons why a gas engine stalls.
Why did the engine start to stall? – The most complete analysis of the reasons
What does the term “Engine Troit” mean?
I ask this question at the beginning of the article in order to cut off the “couch experts”, and only real car enthusiasts who love and appreciate their car remain here.
Just one of the commentators began to assert:
“Engine tripping is when there is no one cycle in the operation of an internal combustion engine. That is, out of four cycles of engine operation, one cycle was thrown away.”
I explained to him that he was wrong, but he didn’t get it. To prevent such armchair army specialists from wasting their time and “cracking” in the comments, I want to cut them off right away.
Now let's continue the conversation with real car lovers.
Today we will look at the main reasons why the motor may trip. They may seem banal, but read my work to the end carefully, I am sure you will learn something new for yourself.
The car runs on gas
In the life of every motorist there is a situation when the engine misfires, often this means a banal problem with the spark plug or a couple of other well-known breakdowns. But when it comes to the LPG system, sometimes it can be quite problematic to understand why the engine stalls on gas, but works fine on gasoline, and in this case one cannot do without an integrated approach and analysis of the situation. The car runs on gas for various reasons, but often, even a knowledgeable person is afraid to get into the gas installation and understand the problem, entrusting the troubleshooting to specialists.
In most cases, such caution when working with a gas system is justified, because gas is a flammable substance, and any leakage can result in serious problems. But if there is no opportunity to contact specialists, and the car stalls and stalls when running on gas, you can try to figure out the problem yourself.
Reason one - spark plugs
I wrote in detail about how to determine faults in car systems using spark plugs
here .
I recommend reading it - it turned out to be useful, judging by your reviews, thank you.
We unscrew the spark plugs one at a time and look at their insulator.
If it is covered with dense carbon deposits, then it is difficult for a spark to penetrate it. The current seeks the path with the least resistance, so the spark will not be between the electrodes, but will “go” along the insulator to the side. Its energy will not be enough to set fire to the air-fuel mixture. This cylinder will not work.
We inspect the external condition of the spark plug insulator.
If there are microcracks, then part of the current will not be converted into a discharge, but will escape through these damages. You need to look at the internal insulator, which is screwed into the cylinder head, and at the external one, onto which the armor wire cap is placed.
Any chips or damage can lead to poor sparking or its complete absence.
Large or small gap between electrodes.
Many people have heard or know that for certain engines, ignition systems and types of fuel used, spark plugs with a certain gap are required. Usually its value is indicated by the manufacturer of engines and cars.
How to check the spark without special devices on the engine
This is an old, “grandfather” method, some people are afraid of it:
- They unscrewed the spark plug;
- They put an armored wire on her;
- They leaned it with the inner body, the metal part, against the engine;
- Turn on the ignition and turn the starter.
Be sure to hold on to the rubber cap of the armored wire, otherwise your hand will shake violently. This is what many are afraid of
