Refitting Fuel Saving Accelerator Secondary Intake Fuel Saving Accelerator Power Refitting Fuel Saving Device Intake Small Secondary air intake fuel saving accelerator(standard configuration: one secondary air inlet, one with air pipe 800mm, one package of installation acceories)1 Working principle of secondary air intake:In fact, the secondary air intake is a simple fuel-saving accelerator. Its principle is very simple: for the purpose of supplementing the engine, the secondary air is introduced from the intake manifold, and the valve opening volume is changed according to the engine vacuum suction, so as to improve the volume / filling efficiency. Therefore, the air introduced in the state of rapid acceleration matches with the additional gasoline supplied by the acceleration oil circuit to supplement the engine The air in the combustion chamber is insufficient to achieve the ideal gasoline air mixture ratio (fuel saving). Under the normal ignition condition, due to the increase of air, the inflation efficiency is greatly improved, and the oxidation probability of fuel is greatly improved. Therefore, the combustion efficiency is improved, so the fuel consumption rate can be saved by 10% ~ 20%, and the instantaneous torque value can be increased by more than 35%, which can be reflected in the uniform speed, rapid acceleration and idle speed.2 Secondary air intake function and advantages:1. The horsepower, torque and torque are increased by 10% - 30%, easy to start, and the impulse is increased by 0.5-1 times.2. Use the fifth gear to climb the slope strongly, accelerate quickly and increase the first gear.3. After the installation of the product, when the starting acceleration is 0-100km / h, it is 1-3 seconds faster than the original vehicle.4. The average fuel saving rate of normal combustion support is about 10% - 30%. The fuel consumption can be as high as 35% when driving at a constant speed.5. This product can reduce nox-co emiion standard value of exhaust gas and prolong the service life of catalyst converter.6. The product is simple to install (D.I.Y), and will never affect the system structure of the vehicle unit.7. The product can stabilize the voltage and current, reduce the lo of the battery, and protect the battery to increase its service life.8. This product can protect the engine from wear, carbon, oil purity, prolong the service life and reduce the maintenance cost.9. It has a long service life. The service life of this product is limited to three to ten years.10. This product is suitable for all gasoline vehicles.3 Installation and commiioning:1. The secondary air intake is connected at the crankcase exhaust gas recovery pipe. Do not connect at the brake vacuum pipe to avoid affecting the brake.2. Start the engine, adjust the idle speed (rotate the adjusting nut, after the product has effect): because the idle speed will be increased after the product function, the idle speed of the engine shall be restored to the original state through adjustment.3. Lock the lock nut and fix it in a proper position.The installation is very simple. It can be basically completed in 15 minutes in the refitting shop. Moreover, it is non-destructive and does not need to damage any structure.
