Nitro oxide is translated as nitrogen oxide (or paradise gas), used in healthcare as an anesthetic - but we will be interested in its use in cars.

This article continues the performance enhancement series, and we will briefly focus on the Nitro Oxide System, NOS.

All cars are placed in a certain class, depending on their external dimensions, price, and the displacement and power of the engine under their hood. The most important parameter is the length of the car and the wheelbase of its axles.

Classification of cars by class can also be influenced by the manufacturer, who can prioritize or choose the class in which the car will be classified. There are several differences between the individual countries of the European Union in the classification of cars into certain classes.

The engine starter is a device with a primary function allowing the engine to start and run. It converts electrical energy into mechanical energy. A starter is needed by all engines that cannot generate torque on their own when starting.

In this article, we will shed light on the function of the starter, its construction, and its types. In addition, we will briefly look at what can cause a malfunctioning engine starter.

Rough idle troubles many drivers of both old and new cars. However, some drivers ignore this problem and do not even realize how big of a mistake they are making.

Neglecting this problem can cause a whole series of other, much more expensive problems. But what kind of malfunction can cause the engine to run erratically? What to check and what to watch out for? Let's take a look at it.

RPM fluctuation is one of the most common problems among all kinds of cars, regardless of age. This topic has been widely discussed a million times on various automotive forums. However, no one wants to search through long discussions to find an answer to this problem.

That's why we decided to prepare an article with the 12 most common reasons that cause fluctuations in engine speed. To begin with, it should be noted that the RPM fluctuation does not have to be due to just one malfunction.

European emission standards began to be introduced in 1992 for all new cars to improve air quality. At the time of publishing, all new cars sold in the European Union must meet the Euro 6 emission standard.

Most recently, however, the final form of the new Euro 7 emission standard is being negotiated, which should apply in the summer of 2025. What will this mean, what do the other Euro emission standards represent, and what applies to diesel and gasoline engines?
