CreditParts modification technology for the mass market –throttle body
Function
The electronic throttle body is an important component of the automobile engine intake system. It adjusts the engine intake volume and load by controlling the amount of air entering the engine, thereby affecting the engine speed, power output, fuel economy, etc.
Common methods for modifying
Replace with a larger size:
Buy a modified throttle body that is larger than the original factory size.
It usually has a larger inner diameter than the original factory, allowing more air to pass through.
Increasing the throttle diameter can improve intake efficiency and throttle response, making the vehicle accelerate more sensitively.
Throttle grinding and polishing:
Grinding and polishing the original throttle mainly involves fine processing of the inner wall and valve plate surface of the throttle to make its surface smoother, reduce the resistance of airflow, and allow air to enter the engine more smoothly through the throttle.
Preparation before modification
Understand the adaptability of vehicle models:
The throttle structure, size and matching method with the engine of different models are different. Not all models are suitable for throttle modification.For example, it may be difficult to find suitable modified throttle products for some niche models or specially designed engines, and compatibility issues may arise after modification.
Prepare tools:
Basic tools such as wrenches, screwdrivers, sockets, etc. are essential. Basic tools such as wrenches, screwdrivers, sockets, etc. are essential.
Choose accessories:
The quality of throttle modification products on the market is uneven. To choose products produced by regular manufacturers with quality assurance, you can refer to the modification experience and evaluation of other car owners and choose brands and products with good reputations.
Modification steps
Remove the old throttle:
First, disconnect the negative pole of the vehicle’s battery to prevent problems such as circuit short circuits during operation. Then, follow the instructions in the vehicle maintenance manual to gradually disassemble the intake pipe, vacuum tube, throttle position sensor plug and other components connected to the throttle, and finally remove the bolts that fix the throttle, and remove the old throttle from the engine.
Install the new throttle:
Place the new one in the installation position, align the bolt holes, first tighten the bolts by hand to ensure that the throttle body is in the correct position, and then use the tool to tighten the bolts according to the specified torque. Then connect the intake pipe, vacuum tube throttle position sensor plug and other components to ensure that the connection is firm and there is no looseness or leakage.
Throttle matching:
The throttle needs to be matched after replacement. This is to allow the vehicle’s electronic control system to re-identify the parameters of the new throttle.Some vehicles can complete the matching by turning on the ignition switch and waiting for a while for the throttle motor to automatically reset; some models need to use a special car diagnostic instrument, enter the system and select the corresponding operation for matching.
Precautions after modification
Inspection and debugging:
After starting the vehicle, carefully check the running status of the engine, observe whether the idle speed is stable, whether the acceleration is smooth, whether there is any abnormal noise or the fault light is on, etc. If there is a problem, promptly check whether it is an installation problem or a problem with the accessories themselves.
Regular maintenance:
The modified throttle body also needs regular maintenance. According to the requirements of the manual, clean the throttle regularly to prevent the accumulation of impurities such as dust and oil from affecting the normal operation of the throttle.
Risks of Replacing or Modifying the Throttle Body
We have already introduced some of the car throttle body modifications. In addition,poses the following risks:
Risk of hardware damage
- Damage to the throttle: During the installation process, improper operation, such as excessive tightening torque of the bolts, may cause the throttle body to deform or even break, affecting its normal use. In addition, inappropriate throttle products with poor quality may also cause internal component damage during use, such as throttle shaft wear, sensor failure, etc.
- Damage to peripheral components: When removing or installing the throttle body, improper operation may damage other components connected to it.Such as the intake pipe, vacuum tube, etc. Damage to these components may cause intake leakage and affect the normal operation of the engine.
Risk of abnormal performance
- Sluggish or unresponsive: Even after matching, the new throttle body may have problems adapting to the vehicle’s electronic control system.After the driver steps on the accelerator pedal, the vehicle cannot respond to acceleration in time, affecting the driving experience and driving safety.
- Unbalanced power output: The modified or replaced throttle body may not be able to accurately control the intake volume, resulting in the inability to match the intake volume and fuel injection volume of the engine at different speeds.
- Unbalanced power output often occurs, such as sufficient power in some speed ranges and insufficient power in other ranges, which will cause a sense of frustration.
Safety hazards
- Risk of loss of control: If the throttle valve cannot be closed normally, the engine will continue to run at high speed.
- Failure of brake booster: In some vehicles, the working state of the throttle is related to the brake booster system. If there is a problem with the throttle body, it may affect the normal operation of the brake booster system, resulting in a longer braking distance, a worse braking effect, and increased driving risks.
