Background technique
As one of symbol of modern civilization, unquestionable, it is convenient that automobile has brought to people's life, but due to present stage most automobile still adopt oil as main fuel, its environmental pollution problem is accompanied.
Speak of environmental pollution, people can expect haze naturally.The formation of haze and the discharge of pollutant are closely related, and in city, particle diameter is discharged at micron-sized fine particle thing in motor-vehicle tail-gas and other soot emissions source, rests in atmosphere, in the time that inversion, quiet wind etc. are unfavorable for that the weather of diffusion occurs, just forms haze.
According to the research to somewhere haze main source, in atmosphere, diameter is less than or equal in the source structure of particulate matter (also referred to as entering lung particulate matter, PM2.5) of 2.5 microns, and motor-vehicle tail-gas accounts for 1/5th.
From long-range, on the one hand, the essential measure that solves haze is to readjust the energy structure and reasonably urban development planning; On the other hand, the fuel economy of motor and the raising of fuel qualities are progressive processes, promote limited in the regular period.From short-term, the exhaust pollutant discharge amount that reduces at present Motor Vehicle is one of feasible way.
As everyone knows, for fuel engine as long as running just has pollutant emission, this wherein have again quite a few be Motor Vehicle during waiting red light and congestion in road, produce when idle running.And motor car engine idling when idle running, its black carbon emission amount is larger in travelling.For the larger motor of air displacement, its pollutant discharge amount is relatively larger.
Therefore, manage to reduce pollutant of vehicle exhaust discharge amount and become the task of top priority.
For above-mentioned situation, there is automobile manufacturing company in part vehicle, to apply automatic start-stop technology, temporary parking in Vehicle Driving Cycle process, for example, while waiting red light autostop, in the time that needs move on, system autoboot motor.
High during due to the wearing and tearing of motor in the time starting and the running of the equal compared with normal of instantaneous oil consumption, automatic start-stop technology exists increases uncertain etc. the deficiency of engine scuffing and fuel-economizing, reduction of discharging effect.
Current automobile, in order to improve the smoothness of operation of motor, adopts even more multi cylinder composition of four cylinders, six cylinders more.And when idle running, general tree does work outward, motor will maintain certain idling speed, and the Conversion of Energy of oil inflame is in the friction and hear rate of inner zero.
