Installation of the generator smoke-dry A car is a popular way to add visual appeal to your vehicle while participating in shows, photo shoots or themed events. Unlike a conventional smoke machine that ejects steam into or through the hood, car systems are often integrated directly into the exhaust system or installed as independent modules with the pipes out.
The main feature of such equipment is the ability to create dense, swelling clubs that quickly dissipate and do not leave an oily plaque on the body. This is critical for owners of expensive cars who do not want to risk paintwork or optical contamination. Dry smoke generators work on the basis of special liquids that evaporate when in contact with a heated element or mix with a hot exhaust.
In this article, we will discuss the technical aspects of the installation, select the appropriate equipment and discuss precautions. You will learn how to avoid common errors that can damage oxygen sensors or catalysts. The right approach will allow you to enjoy a spectacular visual without harming the technical condition of the machine.
Principle of operation and types of smoke generators
The basis of any generator is the heating element and the liquid supply system. In classical stage instruments used TAENwhich heats the special mixture to the state of aerosol. In automotive conditions, this process can be accomplished in two ways: using an autonomous electric module or implementing a system in the exhaust tract.
Autonomous systems are sealed boxes with a liquid container and a powerful compressor. They are controlled via a remote or mobile app, allowing you to set smoke intervals. Such devices are easier to install, as they do not require deep intervention in the design of the car, but they consume significant current.
Systems integrated into the exhaust pipe use the temperature of the exhaust gases to evaporate the liquid. This solution is more energy efficient and allows for larger effects. However, there is a risk of overheating of equipment during prolonged idling, when the exhaust temperature is not enough for high-quality steam formation.
- 🔥 Electric generators: operate from the onboard 12V network, require powerful wiring.
- 💨 Exhaust injectors: use heat from exhaust gases, more compact.
- 🎮 Control: Possibly via a button in the cabin, remote control or Bluetooth application.
- 🌫️ The smoke is low (smoking) or high (rising up).
The choice of device type depends on your goals. For short-term spectacular trips in the parking lot, a powerful electric module will suit. If you plan a long demonstration in motion, it is worth considering options with combined heating or enhanced thermal insulation.
⚠️ Attention: The use of cheap liquid analogues or low-quality heaters can lead to a rapid failure of the car wiring due to voltage surges or short circuit.
Choosing a liquid for smoke generation
The quality of the effect created directly depends on the consumable material used. For cars, it is strictly not recommended to use ordinary glycerin-based stage fluids in large volumes, as they can leave a sticky plaque. Specialized formulations for motor-use They are designed to take into account an aggressive external environment.
The basis of professional liquids are purified oils and alcohols, which, when evaporated, give a dense white mist. The most important parameter is the evaporation temperature. If it is too low, the liquid will simply flow out of the pipe without evaporating. If it is too high, the heating element can burn.
There are also "cold" liquids, working on the principle of aerosol spraying under high pressure without strong heating. They are safer for nearby plastic body elements, but give less dense smoke. To create the effect of a “burning” car, mixtures are often used, which, when in contact with hot metal, give a characteristic glow.
Always check the compatibility of the liquid with the material of the seals of your generator. Aggressive chemical compounds can corrode rubber pads, causing leaks.
When buying consumables, pay attention to the labeling "Low Residue" (few residues). This ensures that after the show you don’t have to polish the body from the greasy film. Saving on liquid often turns into expensive dry cleaning of the cabin or engine washing.
Installation specifications
Installation of a dry smoke generator requires careful preparation. First of all, it is necessary to determine the place of installation. Most often, equipment is hidden in the luggage compartment, a niche under the spare wheel or in the free space under the hood. It is important to ensure access for refueling and maintenance.
The electric part is the most critical moment. The generator’s current consumption can reach 15-20 Amps at peak, which is comparable to the power of headlights or seat heating. The wiring should be designed for such a load, it is necessary to use a fuse in the break of the supply chain. Connecting directly to the battery via relay is the safest option.
For systems that are introduced into the exhaust pipe, you need to choose a place with minimal vibration. The fastening must be rigid to prevent breakage of the fluid supply pipes. Often required drilling muffler or resonator, which can affect the acoustics of the exhaust and even cause questions from traffic police when checking the design.
☑️ Preparation for installation
Don't forget about the management system. Wires from the remote or controller must be laid away from sources of high-frequency interference, such as ignition coils or a generator. Otherwise, false positives or system failures at the most inopportune time are possible.
Safety of the engine and exhaust system
Introducing third-party equipment into the exhaust system of a modern car is always a risk. Oxygen sensors (Lambda sensors) and particulate filters are highly sensitive to foreign chemical compounds. The entry of vapors of smoke liquid on the working element of the sensor can lead to its irreversible poisoning and error. Check Engine.
To minimize risks, the liquid injection point should be located after the catalyst and sensors, closer to the exhaust pipe cut. This will also prevent the buildup of swelling inside the engine. Some enthusiasts install special valves-cutters that block the supply of fluid when the engine stops.
Temperature is also important. Long-term operation of the generator at idling can lead to local overheating of the exhaust pipe section, where the liquid is supplied. This is fraught with metal burn or deformation of fasteners. It is recommended to use heat-resistant materials and monitor the temperature of the pipe.
| Parameter | Norma. | Critical significance |
|---|---|---|
| Exhaust temperature (idle) | 100-200°C | > 300°C (ignition risk) |
| Exhaust temperature (under load) | 400-700°C | > 900°C (burnout) |
| Generator current | 5-15 AA | > 20 A (risk to wiring) |
| Exhaust pressure | 0.1-0.5 atm | > 1.0 atm (capped catalyst) |
Impact on the guarantee
Installation of uncertified equipment in the exhaust system is the basis for removing the car from warranty service at an official dealer. Any engine malfunction, even indirectly related to changes in exhaust composition or pressure, can be atributed to your modifications.
Legal aspects and rules of the road
The use of smoke generators on public roads is regulated by traffic rules and technical regulations. The main article referred to by the inspectors is the creation of obstacles to traffic and the deterioration of visibility. If your smoke car closes the view of other participants in the movement, this can be regarded as a violation.
In addition, there are restrictions on the color of lighting devices and additional equipment. Although the smoke itself does not emit light, the combination with bright underfloor illumination or neon elements can attract unnecessary attention of the regulatory authorities. In some regions, the use of devices that simulate an emergency situation (for example, smoke from under the hood) may be prohibited.
Use effects only in closed areas, parking lots or in specially designated areas for shows.
⚠️ Attention: The use of smoke effects in tunnels, bridges and in areas with heavy traffic is prohibited. This can lead to accidents and serious legal liability.
Maintenance and troubleshooting
Like any technical device, a dry smoke generator requires regular maintenance. The main enemy of the equipment is the formation of scale on the heating element and clogging of nozzles. After each activity, it is recommended to blow the system with air to remove the remaining fluid.
If the smoke has become less intense or has changed its color, check the air filter (if any) and the cleanliness of the heater. Use special solutions recommended by the manufacturer. In no case do not try to mechanically clean the plaque with sharp objects - this will damage the coating of the TEN.
A common problem is the suffocation of the feeding system. If the pump is working but there is no smoke, check the tightness of the joints and the absence of air bubbles in the tubes. Sometimes it helps short-term increase in pressure or pumping the system idle.
Check your electrical contacts regularly. Vibration when moving the car contributes to the weakening of the connections. Oxidized contact can lead to a voltage drop and inefficient operation of the heater, which ultimately reduces its service life.
Regular prevention and use of high-quality liquids increase the life of the generator by 2-3 times.
Frequently Asked Questions (FAQ)
Can I use regular vape fluid or stage fluid?
Using vape fluid is inefficient due to the small volume of evaporation. Scenic fluid is acceptable, but only if it has a label of low residue content. Conventional compositions can leave a greasy plaque on the glass and body, which is difficult to wash.
How quickly does the liquid run out?
The consumption depends on the power of the generator and the density of smoke. On average, 1 liter of professional fluid is enough for 15-20 minutes of continuous work or for several dozen short "puffs" during a photo shoot.
Is it safe for a turbocharged engine?
If the input point is located after the turbine and catalyst, there is no direct harm to the engine. However, the hit of liquid on the hot turbine can cause thermal shock of the metal. Be careful with the installation point.
How to remove the smell of smoke from the cabin?
Although the smoke is called “dry”, the smell can persist. Help ventilation, replacement of the cabin filter and the use of an ozonator. Avoid puffing smoke into the ventilation system through open windows while the generator is running.
Do I need to register the installation in the traffic police?
Formally, the installation of additional equipment that changes the design of the exhaust system or creates interference may require changes in the PTS. In practice, this is rarely checked if the device is not permanently on while driving on public roads.
