Four, the highway traffic saving tips

      1 60-90 km per hour speed the most fuel-efficient driving. In the vehicle, use the highest gear, maintain economic speed, wear to the minimum, the most fuel-efficient. General manual speed of the car more than 60-90 km / h.
      2 rapid acceleration than slow speed fuel consumption of more than 30%. Rapid acceleration, engine fuel supply system and fuel supply quantity increases suddenly, resulting in fuel mixture thickens, the fuel combustion is not sufficient, resulting in a waste of fuel, and tire wear a 70 fold increase; the rapid deceleration, braking strength generally larger, the vehicles need to consumption of large kinetic energy can be achieved quickly to slow or stop to accelerate or started is a waste of time, and a waste of fuel.
      3 haste car or car with a car or an insert.. In intersection congestion to patience with the car driving, not anxious acceleration follow-up or from both sides of the bypass interspersed, so as to reduce the rapid acceleration, rapid deceleration and stopping times. At the intersection of the intersection in advance estimated traffic lights change, adjust the speed, ahead of time to slide, avoid in the intersection every time the parking and the sudden brake, resulting in fuel consumption increased.
      4 m in advance when 500 m was slightly accelerated. Uphill driving can be slightly accelerated in the first 500 meters, starting uphill can reduce the intensity of stepping on the accelerator pedal, relying on the inertia of the vehicle slope. Not rushed to the top of the hill to change into the low gear.
      5 frequent variable straight driving fuel consumption of 12% more than. Frequently change lanes, you need to constantly change speed, rapid acceleration, braking, engine has been in an unstable state, driving distance is extended, so that a lot of petrol in imperceptible in into the not fully burning exhaust.
      6 short distance travel best not to drive. Short distance driving, the vehicle has not yet heating up to stop, if frequent short distance parking — — starting, will make the vehicle more than 5 liters of fuel consumption.
      7 of the high speed air conditioning fuel consumption than windows. Vehicle at high speeds, the car window will increase the air resistance, increased fuel consumption, increased fuel consumption will be more than the use of air conditioning consumption. Usually, the speed of more than 80 kilometers per hour, the air conditioning window than fuel. The summer time in the sun park vehicles, air conditioning, should open the window to cool the hot air discharged.
      50 kg of 8 kg of goods more than 4 liters of oil. The car as far as possible to avoid useless items. A small passenger car if placed 10 kg useless items along with the car driving 1000 kilometers, will consume more than 0.8 liters of oil.
