Background technique
Because fossil energy storage is limited, and especially because as the limited usability of raw material of the mineral oil that obtains operation explosive motor fuel, people when the exploitation explosive motor ongoing effort to minimize fuel consumption.On the other hand, improvement, just more effective burning is the prospect of these effort.Yet on the other hand, some strategy about the explosive motor basic operation is a novelty.
The notion of improving fuel consumption in vehicles is, if not instantaneous power demands, closes explosive motor but not continues to make it to work in idling.In the practice, this means that explosive motor cuts out at least when stationary vehicle.The application of this notion is the stop-go traffic, and it appears at the motor vehicle road and main stem stops up.In urban transit system, because the existing inharmonic each other result of traffic light systems, the traffic of stop-go is the exception outside the rule no longer.Restricted junction railway etc. provide further example.
Be intended to reduce the strategy of the fuel consumption in the explosive motor taxi operation, wherein do not have the instantaneous power requirement similarly, wherein similarly, do not have the starting point power requirements, and have starting point similarly, and also can make up with the notion of type noted earlier.
The strategy of all minimizing fuel consumptions all is based on the conventional method that reduces the break momentum in the taxi operation, the break momentum is transferred to driving system by explosive motor in taxi operation, thereby the distance that reduces retardation and therefore extended and travelled owing to vehicle energy from given car speed v.Because supply of fuel is closed usually in taxi operation, promptly to stop using, the whole fuel consumption of vehicle reduces by the distance that increases vehicle driving in the taxi operation, calculates because fuel consumption is the distance that the fuel from used fuel quantity and this amount travels.Compare aforementioned concepts, explosive motor is not to cut out but continue to operate in the idling.
In situation of the present invention, traditional taxi operation can be regarded as the serviceability of explosive motor or vehicle, and wherein the clutch closure promptly, meshes, and does not have load request, and just, the driver does not activate accelerator pedal.In situation of the present invention, all types of taxi operation common ground are not have load request.
According to prior art, the air throttle that is arranged on air inlet duct is closed fully in taxi operation, therefore along with piston continues vibration, produces negative pressure in the air throttle downstream, causes so-called explosive motor suction.As a result, must carry out extra inflation exchange work.Inflation exchange work forms the major component that is transferred to the break momentum that drives system in the taxi operation from explosive motor.
The strategy that reduces fuel consumption in the taxi operation is also at Automobiltechnische Zeitschrift, and 1999, No.9 illustrates among 438 pages of ff, its hypothesis clutch breaks away from taxi operation, and clutch and the remainder disconnection that drives system.In this mode, the retardation of motor vehicle reduces, because the break momentum normally is transferred to vehicle by explosive motor in the taxi operation, thereby is eliminated as the deceleration factor.Mainly determine the vehicle deceleration that clutch breaks away from then by rolling resistance and resistance of air.Yet using this tactful prerequisite is automatic actuatable clutch, the clutch that just can utilize electronic control system to activate, and need not the driver intervene just become movable.This respect, this strategy can be used in the motor vehicle of any clutch that is equipped with manually actuable.
Even for the drive cycle of determining the fuel consumption appointment generally includes the decelerating phase that requires the actuated vehicle break, this is owing to relate to big relatively deceleration gradient, therefore and be unsuitable for that fuel consumption is by reducing the strategy that the break momentum reduces in the wherein explosive motor taxi operation, in the real road traffic, the retardation stage day by day increases the frequent generation in ground, it is characterized in that little deceleration gradient, and wherein fuel can utilize the strategy of the type of discussing to save.
