Thing discharge is limited and measuring method (Double idle state method and simple condition method)》：Idling operation refers to electromotor tick-over state, i.e.,
Clutch is in binding site, variator in neutral gear position (for the car of automatic gear-box should be at " STOP " or " P " shelves
Position)；Using the car of carburetor oil-supply system, choke should be at fully open position；Gas pedal is in and is totally released position.
Engine idling performance has considerable influence to discharge, oil consumption and comfortableness, therefore, engine idling performance is to evaluate
The important indicator of engine performance.During idling, reasonable match system is separated and gas pedal is totally released, and electromotor is only gram
Take self resistance operating, no external output work.Rotating speed during engine idle is referred to as idling speed, and idling speed is unsuitable too high
Or it is too low, it is too high to increase oil consumption, it is too low that engine idle rotational can be made unstable.Ensure the minimum of engine stabilizer operating
Idling speed is optimal idling speed.

Driving idle speed value is improved it is necessary to corresponding to overcome the moment of torsion of resistance demand bigger；Coolant temperature is identical, and height above sea level is higher, empty
Gas oxygen content is lower, is to ensure air inflow, meets engine torque demand, will also arrange higher row car idle speed value, to overcome
Electromotor running resistance, guarantee engine work and car load normally travel.
But, under identical height above sea level and coolant temperature, the driving idle speed value of different gears is identical, it is impossible to embody each
The torque demand of gear is different, and when meeting low-grade torque demand, during change up, moment of torsion is not enough, acceleration can under
Drop, starts to accelerate from driving idling, and booster response is slow；And when high-grade torque demand is met, change down then can torque surplus,
Certain impact is had to vehicle, pause and transition in rhythm or melody sense is produced.So each gear arranges identical driving idling speed value, just appears in not
During with switching between gear, cornering ability has significant change, not in optimum state, it is impossible to meet demand of the client to driving.
Be therefore, it is necessary to a kind of method of engine speed when researching and developing new setting driving idling, it is considered to gear etc. its
His factor, is that passenger brings more comfortable experience.
