1, function overview: adopting high-performance integrated micro-control design, improving hardware design, optimizing software function, faster processing speed, applying many new technologies, and built-in hardware watchdog and ultra-high-speed conversion control, it has excellent performance in cold start-stability-power-fuel saving rate. Many user parameters are built in, which can be adjusted by software. According to different vehicle conditions and different methanol-gasoline mixing ratios, the best results can be achieved by configuring parameters through the debugger.
2. Realization principle: The fuel injection system of the original car is not changed, and the fuel injection time and pulse width of the original car computer are collected after the voltage is changed by the optical coupler. The timing fuel injection technology is adopted, and the methanol gasoline mode is identified by the microcontroller, and then the fuel injection system of the original vehicle is output and controlled. The output adopts Schmidt trigger circuit, with accurate output signal, high-speed and efficient protection circuit, stable performance and strong power. High fuel saving rate.
The program deals with the error of pulse ignition signal of single chip microcomputer, and its accuracy is twice as high as that of general controller. The engine is more stable than other controllers at idle speed and running state, and the error fuel consumption is reduced.
It can burn not only gasoline, but also pure methanol. It can also be mixed and burned in any proportion.
1, the previous universal methanol-gasoline two-speed conversion controller, the actual fuel consumption is not ideal, but the newly developed controller of our company can make it better suitable for all mainstream cars on the market at present. 2. The methanol controller developed by Bai Tong New Energy Automobile Development Co., Ltd., which is the most fuel-efficient, can adjust the fuel injection amount by itself and save as much as you want, and you can set the 3-speed fixed mode. Methanol mode, gasoline mode, methanol-gasoline mixed mode. 3. Super anti-interference The methanol controllers developed by our company are all integrated with internal watchdog. Maybe some people don't understand the meaning of opening the door dog. Here's an explanation. The role of watchdog is to prevent the program from getting out of control. As we all know, the electronic environment of automobile is very complicated, with many interferences and high temperature near the engine. For a reliable automotive electronic product, some methods must be added to prevent the car from stopping suddenly. Therefore, all methanol controllers in our company have introduced internal watchdog, which can be automatically reset and re-developed when the program is out of control unexpectedly. The workflow of watchdog: ECU is powered on, watchdog is started, and the program runs. During the running of the program, ECU should feed the dog every few milliseconds. If there is an accident in the program, the ECU will not feed the dog within the specified time, and the watchdog will immediately reset the ECU to restart the program. In tens of milliseconds, even if there is an accident, it can return to normal. 4. Super protect the methanol controller developed by our company, and never consider the cost. Recently, many methanol controllers have been found, even without optocoupler isolation, which is the white chip in the picture. This is the best protective isolation chip for automotive electronic chips, and many controllers don't have this kind of chip. 5. Ultra-low power company specially customized the driver chip for the automobile fuel injector. By using the patch technology, the volume is reduced by half, which effectively reduces the power consumption of the whole system by more than half, and provides good and reasonable protection for the load of the automobile engine. It also meets the requirements of the current society for energy saving and emission reduction of automotive electronics. When using methanol gasoline, there will be several common faults of vehicles, as follows: (1) Air resistance in hot weather in summer. Theoretically, the vapor pressure of methanol gasoline will increase after containing alcohol, but the vapor pressure is strictly controlled after oil products are mixed, and generally there will be no gas resistance. Driving in summer, when turning on the air conditioner, driving at high speed with high power and load for a long time, driving at low speed for a long time in urban areas, especially turning on the air conditioner for a long time after parking, the ignition time is too late, and the mixture is too thin. , will lead to the starter temperature rise, resulting in air resistance. As long as the above points are well understood and mastered, there will be no air resistance caused by excessive engine temperature. (2) poor start and acceleration. The appearance of poor start-up acceleration is generally related to poor oil circuit, which leads to insufficient oil supply and too thin mixture. The solution is to check the cleaning oil circuit and adjust the ignition time. (3) Poor oil supply. The solution is to check the oil circuit and eliminate the fault. Through the summary of previous use, it is often because the fuel tank is not cleaned. After using methanol gasoline, impurities such as colloidal particles originally stuck on the fuel tank wall are washed away, blocking the gasoline filter or fuel nozzle. Cold start of methanol gasoline for vehicles: Cold start of methanol gasoline for vehicles in winter is a major indicator, which is mainly determined by the scientific and technological content of additives. The low temperature resistance of methanol gasoline for vehicles can reach -55℃, which can fully meet the requirements of national use. Influence of using methanol gasoline on bus power and fuel consumption: The actual operation test shows that the bus using methanol gasoline can be used normally without changing the engine, with stable power and basically flat fuel consumption. The use of methanol gasoline for vehicles is the influence of damaging automobile fuel system parts: the corrosion tests of methanol gasoline for vehicles and metal parts used in automobiles under different conditions and the disintegration inspection of vehicles driving more than 200,000 kilometers show that methanol gasoline for vehicles has no signs of corrosion on the appearance of automobile carburetor bottom shell and automobile oil system metal parts, and is not affected by normal temperature changes. The adaptability of methanol gasoline for vehicles to the original rubber parts of automobiles and the disintegration inspection test of vehicles driving more than 200,000 kilometers show that methanol gasoline for vehicles will not cause corrosion and swelling problems to most rubber parts of automobile fuel system, but some rubber parts of some models will not be applicable. Requirements for rubber adaptability of methanol gasoline for vehicles: chloroprene rubber, cis-polybutadiene rubber, styrene-butadiene rubber, nitrile rubber and silicone rubber have good oil resistance and swelling resistance of methanol gasoline, and can be used for automobiles burning methanol gasoline; Nitrile rubber, chlorinated polyether and butyl rubber have poor oil resistance and methanol gasoline expansion resistance, so they are not suitable for cars burning methanol gasoline. Automobile methanol/gasoline flexible fuel automatic converter is an engine control device that can use methanol and ethanol as dual fuels. Without changing any system of the vehicle, methanol gasoline, national standard gasoline and ethanol gasoline can be freely selected. Advantages of Bai Tong Automobile Methanol Controller of Shandong Bai Tong New Energy Automobile Development Co., Ltd.: 1. Strong power: methanol gasoline has the function of self-oxygen supply in the combustion process, which makes the combustion more fully and evenly, improves the thermal efficiency and enhances the power.
