Description

A kind of method that engine torque is optimized based on intake pressure wave
Technical field
The present invention relates to a kind of engine control technologies, more particularly to a kind of maximum based on intake pressure wave optimization engine The method of moment of torsion.
Background technology
As motorcycle engine is single cylinder engine, its gas handling system is fairly simple, an only single air inlet pipe, passes through Air filter removes impurity and dust in air, under TPS control, enters air intake duct, and fuel oil sprays Using intake port injection or engine in-cylinder direct-jet；And motorcycle engine rotation speed change haves a wide reach, and motorcycle starts Machine gas handling system is with regard to a single air inlet pipe；When optimizing to motorcycle engine gas handling system, general it is difficult to take into account low Fast operating mode, middling speed operating mode, high-speed working condition etc.；Because the torque curve of motorcycle depends on coefficient of charge, i.e. intake pressure wave, fill Coefficient of discharge is bigger, and in motorcycle cylinder, air is more, and in the case where air-fuel ratio is certain, the fuel oil for spraying into engine is also more, Bigger moment of torsion and power can be sent；Different manufacturers are to pursue motorcycle engine to meet different operating modes, by air inlet The maximum of pressure wave is fixed on different rotating speeds, and motorcycle engine is needed under different rotating speeds in different operating modes Pressure wave when, the rotating speed residing for gas handling system required pressure ripple maximum is different, it is desirable to air inlet pipe for motorcycle engine Road can become, and air fully evaporates mix temporally variable in the duct with fuel oil, so as to adjust in the range of different rotating speeds most High pulling torque value.
For peak torque during speed operation, motorcycle engine gas handling system pressure wave maximum in low regime, Motorcycle engine in-cylinder combustion is entered when TPS is opened, now as air is mixed with fuel oil Even, burning is quick, discharges pollutants few, and engine start fast response time meets the demand of low-speed big, meets low speed and adds Speed is fast to wait Consumer's Experience；And when engine speed is raised, is wanted to air inlet more and rate request is quicker, at this moment, engine enters Tracheal system wants slightly shorter point, admits air into speed in motorcycle engine cylinder and a little louder, accelerates burn rate, thermal technology's transformation efficiency Accelerate, i.e. toward the elevated region movement of rotating speed, maximum torque is also moved pressure wave maximum toward rotating speed riser region；Satisfaction is rubbed The acceleration of motorcycle driver and crew is required；And when motorcycle engine rotating speed is too high, air inflow is increased, it is necessary to it is motor Car engine air inlet pipe is short, and gas flow resistance is little, and therefore motorcycle engine pipeline is straight, reduces flow resistance and gas Flow losses, accelerate the flowing of gas, accelerate the mixing velocity of air and fuel-steam, carry motorcycle engine volumetric efficiency Height, improves motorcycle engine charging efficiency, so as to intake pressure wave maximum is moved toward high speed area, maximum torque Move toward high speed area；Therefore, to the motorcycle engine changeable with operating mode, and required maximum torque is different Moment of torsion required for rotating speed is different, and its traditional single gas handling system is difficult to meet.
