How often should the throttle body and fuel injectors of a car engine be cleaned?

It is recommended to clean the throttle body and fuel injectors of a car engine every 20,000 to 40,000 kilometers. However, cleaning the throttle body too frequently is not beneficial. Over-cleaning can gradually remove the special coating inside the throttle body cavity. Without this coating, the cavity is more prone to oil buildup, which can accelerate the aging of the throttle body or increase its load. On the other hand, if the throttle body is not cleaned for a long time, the accumulated carbon deposits and impurities can affect the accuracy of the throttle opening. This may also allow air containing impurities to enter the combustion chamber, disrupting the normal operation of the engine. The most noticeable symptoms include unstable idling, a sudden feeling of fuel cutback during normal driving, significantly reduced power, increased fuel consumption, and in some cases, even difficulty starting the engine.

Common Troubleshooting for Electric Quadricycle Controllers

Common troubleshooting methods for quadricycle controllers are as follows: 1. Turn off the ignition lock, if there is resistance when gently rotating the motor, it indicates that the controller's MOS tube is damaged. 2. Connect only the power line to the controller, measure the voltage at the controller's power output terminal with a multimeter. If the voltage is <4V, it indicates an internal fault in the controller. 3. The "abnormal condition" caused by damage to the motor Hall sensor indicates a problem with one of the phase line circuits inside the controller. Additional information about electric quadricycle controllers is as follows: 1. The electric quadricycle controller is the component that controls the motor's rotation. 2. If the controller is damaged, it may cause short circuits, burn out the electric vehicle's fuse, or trip the circuit breaker.

What are the functions of a header exhaust system?

Exhaust headers are used to monitor the air-fuel ratio and reduce the pollution levels of exhaust gases as they exit the engine, thereby achieving environmental benefits. Below is a detailed introduction to exhaust headers: 1. Exhaust headers generally refer to the part directly connected to the engine's exhaust system, mainly consisting of three components: metal connecting pipes, flexible joints, and high-flow metal catalytic converters. 2. After modifying the exhaust headers, it can increase the car's power, improve acceleration in the mid-to-high range, and make exhaust emissions smoother. When combined with modifications to the mid-section of the exhaust system, the effects become even more pronounced. This is especially beneficial for vehicles using aftermarket engine control units (ECUs), ECU tuning, or turbocharged engines.

What are the consequences of not replacing the exhaust valve on the Sail 3?

The impacts of not replacing the exhaust valve on the Sail 3 are as follows: 1. It will be unable to control the amount of exhaust gas recirculation. Excessive exhaust gas participating in recirculation will affect the concentration of the air-fuel mixture, potentially causing difficulties in starting, engine shaking, unstable idling, and weak acceleration, all of which can impair engine performance. 2. If the exhaust valve is damaged, it may lead to the car burning engine oil, with blue smoke coming from the exhaust pipe. The exhaust valve functions to separate oil and gas; under normal operation, it only draws in exhaust gas and not oil. When the exhaust valve is damaged, it loses its oil-gas separation capability, potentially sucking in oil along with the gas, allowing oil to enter the combustion chamber, resulting in oil burning and blue smoke emission.

What is the tire size of the Honda Avancier?

The Honda Avancier uses 245/55R19 tires for both front and rear wheels, with a non-full-size spare tire. The Avancier is a mid-size SUV produced by GAC Honda, with body dimensions of 4816mm in length, 1942mm in width, and 1669mm in height. In terms of power, the Avancier offers a choice between a 1.5-liter turbocharged engine and a 2.0-liter turbocharged engine. The 1.5-liter version delivers a maximum horsepower of 193 PS, a maximum power of 142 kW, and a maximum torque of 243 Nm. The 2.0-liter version provides a maximum horsepower of 272 PS, a maximum power of 200 kW, and a maximum torque of 370 Nm. For transmission, the 1.5-liter Avancier models are equipped with a CVT continuously variable transmission, while the 2.0-liter models come with a 9-speed automatic transmission.

What is the engine RPM when the car speed is 100 km/h?

Generally, when a car's speed reaches 100 km/h, the engine RPM is around 3000. Below are specific details about engine RPM: 1. During cold start, if the idle RPM is below 800/min or above 1200/min, it indicates poor engine condition. 2. While driving, try to avoid letting the engine operate below 2000r/min. If the RPM is too low, the engine will lack power, and the excessive load at low RPM can damage the engine and easily lead to carbon buildup. 3. When the engine operates above 4000r/min, the combustion time shortens, fuel doesn't burn completely, and fuel consumption increases significantly. If driving normally in fifth gear, the speed usually reaches 150km/h, which is already a relatively dangerous speed. 4. The most economical engine operation is between 2200~3500r/min, where the engine performs best. It's advisable to keep the RPM within this range during regular driving.
