Performance verification of heavy-duty motorcycles adjusting intake and exhaust timing

Heavy-duty locomotives with large exhaust vehicles have become a common means of transportation for Taiwanese. However, for car owners to increase power output, improve efficiency, and reduce fuel use, the original factory has designed demand settings for cost, environmental protection, and regulations. This leads to the sacrifice of the performance of the original car design, so the RC2 Super ECU is used to replace the original injection computer, and the air-fuel ratio, ignition angle and exhaust pipe are modified. Without the need to change the structure of the heavy locomotive, the horsepower of the heavy locomotive is improved. It is pointed out that the modification of these three original factory settings has greatly improved the overall speed performance of the heavy-duty locomotive horsepower. Therefore, it is proposed that “heavy locomotive performance verification by changing the timing of intake and exhaust” is mainly to verify the performance benefits and performance brought about by modifying the air-fuel ratio, ignition angle and exhaust pipe.

Performance verification test of coaxial centrifugal clutch for motorcycle transmission system

With the popularization of motorcycles, the demand for motorcycles is getting higher and higher. Therefore, the improvement of power output, the reduction of pollutants discharged, the replacement of waste, the improvement of efficiency and the reduction of fuel use, are also relatively important. Stop-and-go on urban driving will keep the clutch in a state of being engaged and not engaged. The clutch cannot be engaged and is constantly worn. The output efficiency of the CVT belt-type continuously variable transmission system clutch used in the transmission is only about 70~80%. Transmission efficiency. Furthermore, since the traditional CVT belt-type system clutch mainly relies on the action of the centrifugal roller to change the reduction ratio, when encountering different driving conditions and need to accelerate and decelerate, this will make the working area of the internal combustion engine in an unstable state. The matching structure between the automatic clutch weight and the telescopic spring in the reciprocating separation state and the fitted state is replaced, which effectively reduces the problem of uneven contact surfaces of the plates in the past, and prevents the elastic aging from affecting the uniform transmission of power, resulting in the entire dry clutch The life span of the engine is improved and the efficiency of power transmission is maintained, thereby reducing fuel consumption and producing more complete engine power. Therefore, the “Design Performance Verification of Coaxial Contact Centrifugal Ball Clutch” is proposed mainly to verify that the coaxial contact centrifugal ball clutch has better performance than the CVT belt-type clutch.
