A performance increase of up to 100 percent at an affordable cost with a nitrous oxide engine seems tempting, but is only allowed for racing cars. Nitrous oxide injection is an inexpensive method of increasing engine performance by up to 100 percent, but this increase is rather theoretical. Although 100 percent can hardly be achieved with minimal modifications, 30 to 65 percent can still be achieved. However, a more extensive modification would be required to actually double the performance. But how does it all work? The delivery of nitrous oxide allows more oxygen to be delivered to the engine more quickly than normal. This burns more fuel in less time, allowing for a short-term increase in performance. However, the full utilization of a nitrous oxide system is often accompanied by increased wear on the engine and drive.
How does the nitrous oxide injection work?
The laughing gas is heated to around 500 degrees Celsius and breaks down into its components (nitrogen and oxygen). As a result, the oxygen content in the combustion chamber is increased and more fuel can be burned, which leads to more intensive combustion and a corresponding increase in performance. Is installing a nitrous oxide system difficult? Compared to other methods of increasing performance, this variant is relatively easy and cost-effective to implement. The simplest (dry) nitrous oxide injection is the most cost-effective, but also leads to increased wear, since only nitrous oxide and not additional petrol is fed in here. The slightly more complicated (wet) injection is more expensive and supplies the engine with a suitable mixture of gas and fuel. However, the increase in performance is somewhat delayed here. However, this variant is gentler on the engine.
Is street use legal?
Legal use on public roads is (strongly restricted) is also possible. With additional modifications (e.g. brakes), the legislator allows the use in individual cases. Normally, however, nitrous oxide tuning is reserved for racing vehicles. What belongs to the system? A nitrous oxide system consists of a pressure bottle with the nitrous oxide supply, which is usually installed in the trunk or under the seat. This bottle supplies the engine with gas, which when heated decomposes into nitrogen and oxygen. The increased oxygen supply allows more fuel to burn in less time, resulting in a significant increase in performance. An oxygen content of up to 36 percent can be achieved here. In comparison, normal breathing air contains 21 percent oxygen.
Is nitrous oxide injection suitable for continuous operation?
The activation of the nitrous oxide injection takes place by opening the bottle (or a system that does it), so the user can determine the time himself. However, a nitrous oxide injection not for continuous operation designed. It is intended to generate short power peaks. In addition, the supply of nitrous oxide is limited. A 10 pound gas bottle (approximately 4,6 kilograms) will last approximately 5 minutes. During the nitrous oxide injection, the fuel supply must also be increased. There are two types of nitrous oxide injection systems: the wet system (also known as wet system) and the dry system (also known as dry system).
The "Wet System", the safer variant, supplies the combustion process with a ready-mixed fuel and nitrous oxide via special mixing nozzles. With modern nozzles, an increase in performance of up to 20 hp per cylinder (depending on the engine) can be achieved. Special nozzles can even provide up to 40 hp more power. However, the conversion is more complex than the dry system, in which the gas is fed to the engine without additional petrol. A quick and strong increase in performance is possible here, but it is also associated with high wear and tear, and engine damage may even occur under certain circumstances.
Advantages and disadvantages of nitrous oxide injection:
| Benefits | Disadvantages |
|---|---|
| Possibility of short-term, high performance increases | With frequent/long use, the gas supply is quickly used up |
| Activation as needed | High load on the engine and drive (especially in series production) |
| Easy and inexpensive installation | Legal operation and registration not possible in many countries |
| Comparatively inexpensive compared to other tuning methods | Potential safety hazards, including the possibility of explosion |
| Not a permanent mod - can be removed if needed | Can lead to a shorter engine life due to increased wear |
| Works well with existing engine modifications | Increased fuel consumption during activation |
| Can be used in many different vehicle types | Requires additional space for storing the nitrous oxide canister |
| Increases the efficiency of combustion | May affect the vehicle's warranty |
Of course, that wasn't the end of it!
