Study Of Test Method On Dynamic Test Bed Of Motorcycle Engine

With the current energy crisis and increasing awareness of environmental protection, and formal implementation of Euroâ…¢emission test standard of motorcycle in 2008, Motorcycle engine of research and improving the dynamic performance made explicit and more urgent. The performance tuning based on the engine state test don't adapt to the research of the actual working conditions in the dynamic conditions. JS-API Dynamic Bench provides engine test platform for systematic study the dynamic performance of motorcycle engine.For the basic requirements of the general requirements and pilot projects of building dynamic bench of motorcycle engine,study the principles and selection problems Of the dynamometer and throttle actuators, and other major equipment. Proposed the control principle and the construction of software of dynamic bench motorcycle engine.According to the structural characteristics of motorcycles, established a vehicle model, Include: load, transmission, clutch, throttle, brakes and other models. on the basis of model in the throttle and clutch, the simulation of start from rest and shift process were achieved in the dynamic bench. the highest speed, sliding distance test, beyond the acceleration and constant speed fuel consumption, such as road test were conducted in dynamic bench. test results were compared with the chassis dynamometer.Operating characteristics of a pilot longitudinal model was established. Including the shift schedule model and the speed trajectory tracking model, And conducted simulation in the dynamic bench. The impact of driver's accelerator operation speed was researched and analysis on the dynamic bench. The influences with shift schedule, the operation of throttle and clutch on the vehicle power and economic were studied. Use of vehicle models and operating characteristics of the driver model, the stateâ…¢UDC driving cycle test was implemented on the bench of motorcycle engine, were analyzed with the speed of Standards and regulations.This paper focuses on the dynamic performance test method of motorcycle engine, through the dynamic testing system of motorcycle engines, a dynamic test method for motorcycle engine was established first time in the country, the engine test bench can simulate the actual Load, drive, driving behavior by driving the motorcycle, to test and study the actual dynamic characteristics of motorcycle engine; study the testing, analysis and performance assessment methods for dynamic conditions of motorcycle engine on the dynamic test bench of motorcycle engine.
