Study of powertrain matching methods based on fuel consumption by Ministry of Transport
In order to reduce the combined fuel consumption of the Ministry of Transport,the trial summary and simplification of the calculation formula for accelerated fuel consumption revealed the characteristics of accelerating the operating conditions with the instantaneous fuel consumption(L/km)ratio of current vehicle speed to the instantaneous fuel consumption of the previous vehicle speed being close to a constant 1,and identified the factors influencing the consumption standard of fuel of the Ministry of Transport.The erroneous perception that total drag,overall mass,and transmission efficiency determine fuel consumption during acceleration conditions was corrected.By selecting the type of matched powertrain,the development trend of the MOTC fuel consumption standard guiding the complete vehicle plant to match direct transmission and small ratio drive axle was clarified.
