Fuels used for internal combustion engines have become quite expensive these days. For this reason, it is shown as the cheapest alternative among these fuels. LPGThe transition is increasing day by day. So, is LPG, which is cheaper than other fuels, harmful to cars?

Actually, this is a question many people ask themselves. Because in our country There are too many LPG cars. However, there are people who want to switch to LPG, even though they currently run on petrol. Then let’s look at the effect of LPG on the engine.

Does LPG affect vehicle performance?

It is stated that LPG vehicles experience some loss of performance. This information is not completely wrong, but it does not have as great an impact as one might expect. Even if the car’s LPG tuning is done correctly, it can be done in everyday driving conditions. performance loss may not be noticed. The places where LPG lacks power, however small, can show up as very high speeds, under heavy load and sudden accelerations.

Actually, there are two reasons why LPG causes performance loss. The first of these be a fuel with lower energy consumption. The other is that the engine is not designed for LPG. Standard engines burn by combining fuel and air. This is done with a combination of “petrol” and “air” in a petrol car. Because gasoline takes up less space due to its liquid state, much more air can enter the cylinder. However, when LPG fuel is used, air is not the only gas that enters the cylinder. Since LPG is also in gaseous form, some air may be missing from the fuel + air mixture.

What kind of fuel is LPG?

LPG seems to be a more polluted fuel, unlike petrol and diesel, but this is actually a misconception. First of all, LPG is a cleaner fuel than diesel or petrol. LPG contains approximately 24 megajoules of energy per litre. (There is 32 megajoules of energy per gallon of gasoline) LPG, which has over 100 octane rating, is actually liquefied petroleum gas. The fact that LPG is a high octane fuel has an important advantage: the vehicle does not beat in this way.

Let’s briefly explain the knock:

The knock occurs in the cylinder on the compression stroke in the engine. due to the temperature of the fuel and air mixture It is a condition that occurs due to premature inflammation. It reduces vehicle performance and shortens engine life. Octane indicates how difficult the fuel is to ignite. In other words, the higher the octane number of a fuel, the harder it is to burn.

So, does the LPG system damage the engine?

LPG naturally has its advantages, but that does not mean that it does not damage the engine. First of all, LPG is a cold-burning fuel. As a result, it produces less power. Drivers to get this power press more pedals they are trying to catch up to the performance they are making in gasoline.

LPG gets hotter.

The biggest problem with LPG usually occurs at high speeds. Although LPG has a cooler burning process, evaporation occurs compared to gasoline. creates a higher temperature. This high temperature can cause engine parts to wear out faster in the long run.

Especially the valves of cars that run on LPG can break faster than normal. However, this damage will not be short-term, but rather We can say that it will steal 10-15% of the engine’s total life. This time is an acceptable level in addition to the benefits it brings during use.

Petrol lubrication is not available in LPG.

In general, you have heard that LPG cannot lubricate the engine like petrol. In fact, gasoline is not a fuel that lubricates the engine, but some additives that are contained in it during combustion. Makes the engine oilier. LPG does not contain such additives.

In fact, none of these damages are directly related to LPG. The vast majority of cars using the LPG system are powered by petrol engines. So this Engines are designed to run on gasoline.

The LPG system will be integrated later. If engines are produced directly under the conditions of LPG, this can be achieved, among other things, by increasing the dimensions of the cylinders. problems will be solved easily.

What are the advantages of LPG?

First of all, although LPG is a fuel with lower energy consumption compared to petrol, it is still the cheapest fuel compared to its price. LPG burns 30 percent more per liter than petrol, but we know that the price between these two fuels is almost double. From this point of view, a car with LPG is very more economical We see that he can somehow travel.

LPG is a more environmentally friendly fuel.

In addition, cars running on LPG are much more environmentally friendly than other fuels. Moreover LPG with less CO2 emissionsWe can also say that the vehicle indirectly increases the range of your vehicle. Because a car with LPG can also run on petrol, and an LPG tank will be added in addition to the petrol tank. This increases the range of your vehicle.

Today we talked about the advantages and disadvantages of the LPG system for the vehicle. If you want more content like this, write to us in the comments section.
