Parameter Setting

Parameter Adjustment - power parameters matched with the engine

XThruster®The main reason why the thruster can keep the engine at the best combustion efficiency is that the power parameters of the system are adjustable.

Due to the differences in air oxygen content, fuel quality, and engine conditions in different regions (altitude differences), in order to meet different conditions, but still provide the best match, and meet the preset conditions of engine air-fuel ratio adjustment, we design system with adjustable power parameters.

The setting of this power parameter depends on several basics:

  1. The intake method of the engine: “natural intake” or “supercharged intake”.

  2. The fuel type of the engine: “Gasoline” or “Diesel”.

  3. The location where the nano gas duct of the device is connected to the engine air intake system: “air filter housing” or “air intake pipe”.

  4. The single-cylinder volume (displacement volume) of the engine: For example, for a 4000cc 8-cylinder engine and a 2000cc 4-cylinder engine, the calculated single-cylinder volume is same as 500cc.

According to the data analysis of the system development process, we have formulated the “initial value” of the system power parameters for various displacements and the aforementioned conditions, and you can obtain the “initial value” advice from the dealer.


The “initial value” of the power parameters is the result of long-term verification. Incorrect parameter settings will make the system unable to function effectively, and may also lead to abnormal fuel consumption. These unpleasant results are caused by the thruster and engines. There is an inconsistency in the adjustment of the air-fuel ratio.

Therefore, please do not try to set the “power parameter value” that is not recommended to avoid the system being ineffective.

Parameter Correction - why power parameters need to be rematched

XThruster®During the application process of the thruster, the combustion aids reduce the generation of carbon deposits. Also, due to the cold shrinkage and thermal expansion reaction of the nano-titania crystal itself, and the melting point is higher than the temperature in the cylinder, it can penetrate the carbon film in a high temperature and high pressure environment. Affects carbon deposits already present in engine components.

Therefore, after a period of operation, the existing carbon deposits are gradually peeled off (carbon deposits are cleaned), and the carbon deposits on piston rings, catalysts, EGR, etc. are gradually removed. Although the speed of change is not fast, when it will be used for a long time, that will make some changes to the engine.

For example: the removal of carbon deposits on the piston rings, which will help the cylinder pressure of the engine return to a normal state.

When the carbon deposits in the engine’s cylinders or other intake components are gradually removed, the engine efficiency will recover, and the fuel combustion will also change. In order to meet the combustion conditions at this time, the demand for nano-oxides also needs to be changed.

Therefore, users of XThruster® thrusters must re-calibrate the power parameters after a period of use, which is the key to ensuring that the system can continuously provide the best combustion conditions for the engine.

We suggest that after installing the XThruster® thruster, the vehicle should perform system parameter calibration at least once when the mileage reaches 3000 km, and confirm the suitability of the parameters again according to the method of initial power parameter setting.

Due to the difference in the accumulated mileage of new and old vehicles, the carbon deposition conditions inside various engines are also different, which will affect the timing of parameter correction for the system. Therefore, whether parameter correction is required should be subject to individual vehicle conditions.

For vehicles with extremely high mileage, even a second or multiple parameter corrections are required due to the use of mileage accumulation.

Alternatively, parameter corrections can be made due to large changes in fuel quality, or other factors sufficient to affect engine performance, or at any time when the vehicle feels unresponsive, or the thruster effect is not felt.

The adjustment of power parameters is based on “0.1” as the adjustment unit. In most cases, “minus 0.1” is a more likely option.

Parameter adjustment is performed through the XThruster® thruster app, and the vehicle response must be tested during road driving. Please comply with road safety regulations, entrust the co-pilot to operate, and complete the settings according to the following steps and points, or entrust the installation of the system dealers.

Parameter setting guidelines - small car (gasoline and diesel engines with displacement below 6000cc (inclusive)):

  1. According to the “parameter adjustment” principle, obtain the “initial value” suggestion from the dealer.
  2. Start the engine, and after the engine reaches the operating temperature, set the “initial value” through the app.
  3. Drive your vehicle on expressways or other roads with less traffic control or traffic. at speed > 60 km/h use app set the “initial value”+ / – 0.1 ~ 0.2, with each The parameter change setting of 0.1, the feedback status of the vehicle is as follows:

    After the vehicle accelerates, release the accelerator pedal, the engine speed drops slowly, and the vehicle glides farther.

    Stepping on the accelerator pedal lightly, the engine responds sensitively, the speed rises easily, and the speed increases quickly.

    The engine vibration is reduced, the engine sound is crisp, and the performance is improved. Some automatic vehicles may shift gears in advance (torque change).

    The emission of toxic exhaust gas (CO, HC, NOx) is reduced, the amount of water vapor in the gasoline engine exhaust gas increases, and the sour odor and black smoke in the diesel engine exhaust gas are reduced or eliminated.

    In high altitude hypoxic or high temperature areas, engine power is less affected.

  4. If the feedback of the above vehicles cannot be confirmed on ordinary roads, it is recommended to drive the vehicle on the highway. At speed >90 km/h, Drive a certain distance at a constant speed, cruise at a constant speed, set the “initial value” + / – 0.1 ~ 0.2 through the app, and confirm the parameters with a parameter change of 0.1 each time. Accelerate a little under the condition of constant speed, and the vehicle will have the best response after accelerating. Sensitive feedback is the most ideal parameter value.
  5. The above steps can be repeated within the range of +/- 0.1 ~ 0.2 until the optimal response of the engine occurs, that is, use the product at this power parameter for at least 3000 km, or until the optimal engine response is blurred, and then re-calibrate the parameters.
  6. If necessary, the power parameter is set to 0.0 and the “best parameter value” can be exchanged to achieve two states of “off” and “on” of the propulsion system, so as to feel the difference in vehicle performance between the two.
  7. If it is a manual transmission vehicle, it is recommended to use a fixed gear (such as 3rd or 4th gear) at a stable speed to confirm the smoothness of the engine response during acceleration.

Parameter setting guidelines - large vehicles (diesel engines with a displacement of 6000cc and above):

  1. According to the “parameter adjustment” principle, obtain the “initial value” suggestion from the dealer.
  2. Start the engine, after the engine reaches the working temperature, quickly depress the accelerator pedal two or three times without entering the gear, observe the rising speed of the pointer of the engine tachometer, and feel the engine sound of the engine speed rising. At this time, the system parameter is 0.0, The thruster has no effect, and the vehicle response is the original car state.
  3. The “initial value” setting is completed through the app.
  4. As in step 2, quickly press the accelerator pedal two or three times without entering gear, observe the speed at which the pointer of the engine tachometer rises, and feel the sound of the engine speed rising. Setting “Initial value” + / – 0.1 ~ 0.2, adjust each time the parameter changes by 0.1, and repeat the above steps to find the smoothest and fastest response of the pointer of the engine tachometer. At this time, the engine sound should be the most delicate when the engine speed increases . This is “Stationary Parameter A“.
  5. Drive the vehicle to the road, reduce the “stationary parameter A” by 0.1 ~ 0.3 through the app while driving, and adjust it with each 0.1 parameter change to find the vehicle with the smoothest acceleration during driving. This is “driving parameter B”.
  6. According to experience, “driving parameter B” may be the same as “stationary parameter A“, or “stationary parameter Aminus 0.2 = “driving parameter B“.
  7. If it is a manual transmission vehicle, it is recommended to use a fixed gear (such as 3rd or 4th gear) at a stable speed to confirm the smoothness of the engine response during acceleration.
  8. After obtaining the “driving parameter B”, the feedback status of the vehicle is as follows:

    The vehicle starts and accelerates briskly, and there is no need to downshift in some climbing sections.

    The odor of exhaust gas has become lighter, and the amount of urea (SCR) used in some vehicles has been reduced.

    White smoke and odor reduction for the DPF Diesel Particulate Filter regeneration process.

    Engine vibration and noise are reduced.

    In high altitude hypoxic or high temperature areas, engine power is less affected.

  9. After obtaining the “driving parameter B”, drive at least 1500 km with this power parameter, or until the engine response is blurred, and then re-calibrate the parameters. Usually, “minus 0.1” is a more possible option. In some cases, no adjustment is required, or Parameter correction is required only when more miles are driven to meet the current engine state.
  10. When static emission testing is required, please add 0.2 to “driving parameter B” for testing, and then return to “driving parameter B” after completion.
  11. After completing the first setting, when the vehicle continues to drive and needs to be calibrated for “driving parameter B“, the engine should have changed. After completing the parameter calibration, you can start to observe the fuel consumption. Under normal conditions, when the engine efficiency increases, the fuel consumption will change.

Parameter error - Inappropriate parameter setting.

Due to the vehicle’s own air-fuel ratio adjustment mechanism, the O2 sensor on the exhaust pipe will detect the oxygen content of the exhaust gas. If the system power parameter is wrong and the catalyst is excessively vaporized, the engine will be forced to increase the fuel injection amount, resulting in excessive fuel concentration. , increased fuel consumption, slow engine response.
