Electronics
Accelerate smoothly and timely move to higher gear. For vehicles equipped with a tachometer, better to keep the revs in the range 2000-3000 rev / min. On the flat sections can be ridden and in fifth gear, but sometimes understated speed flow will be higher than fourth at the same speed. If there is no tachometer – guided by the speedometer, shifting from 1st to 2nd at 20-30 km / h, from the 2nd to 3rd – 40 km / h, 3rd to 4th – 60 km / h. Sometimes you can use a transfer switch, for example, the first – second – fourth. When decelerating on the carburetor and fuel injection cars equipped with EPHH, use engine braking, lifting your foot off the gas.
In this case, in a certain range of speeds (1.5-2 thousand rev / min) Electronics cuts off the fuel. On carbureted cars without EPHH economical use reel, ie, the motion to transfer off, if ahead at the traffic light flashes red. In the long stops in traffic or you can turn off at stoplights engine. The general principle of economical driving in the city – to choose the most uniform mode of motion, the obstacle in advance to stop acceleration, going to roll forward or braking engine. Driving a car on the highway like a city on the highway to move uniformly, without unnecessary accelerations and decelerations. The optimum speed, which allows a higher average speed and minimum flow Fuel – 90-100 km / hour. Increase it above 100 km / h leads to a significant increase in fuel consumption. If you often go out of town, spend an experiment: Fill "under the cap," and record the odometer (or reset the testimony daily run).
At a gas station in the last paragraph again Fill up to a maximum, and count rate. The next time you change the mode of driving (eg speed – no more than 100 km / h) and again measure the flow rate. Thus, we can calculate efficient mode for a specific route. If you want to "hang on" to refuel – take a right lane and a minimum speed in top gear. Dispersing over the city as quickly as possible to get in top gear and, accordingly, to "cruising" speed. On long descents, use the engine braking mode, and the gasoline engines without EPHH – rolled forward, but do not turn off your engine! On slippery roads, as well as on steep slopes and mountains freewheeling, do not use. The influence of technology is only serviceable vehicle can provide a minimum fuel consumption. By increasing his lead a number of faults in power systems, ignition and the car's chassis. Part power (and fuel!) is spent to operate the additional equipment. For example, the air conditioner running at peak performance can increase gas mileage by 1-2 l/100 km. Therefore, small speeds (up to 60 km / h) is sometimes more profitable to open a window and does not include air conditioning. Each of these components makes a small contribution. But if the amount can save you 10-15%, it just will be the 40-50 cents, which went up gasoline.
