The fuel economy of the tractor not only saves energy for the country, but also saves the driver the cost and increases the income. In today's high oil prices, the impact is particularly evident. Let's talk about several ways to save fuel.
First, master skilled driving skills and driving skills
We have done such tests. Drivers with different technical levels, driving the same tractor, driving the same 100-kilometer road under the same load, the fuel consumption can vary by 20-25%. It can be seen that the driver's driving operation has a great impact on fuel consumption, mainly reflected in the following aspects:
1. Use safe sliding fuel. When the tractor is driving, the power of the engine is cut off, and the inertia is used, which is called sliding. Sliding not only saves fuel, but also plays a role in reducing wear and tear and extending tire life. The use of taxiing must ensure safety and the technical condition of the vehicle is good, especially the braking and steering devices should be effective and reliable; the driving operation is skilled; the road is wide and straight, the line of sight is good, and the traffic conditions are not complicated. There are three common types of sliding: (1) slow down. When the tractor is approaching the parking place, red light, turning, crossing the bridge or encountering obstacles in front of the need to decelerate, you can use the off-speed deceleration sliding method to use inertia to save fuel. (2) Speed ​​up the taxi. It is suitable for use on roads with wide, wide and uncomplicated traffic conditions. When the vehicle speed reaches high speed, the gear is off-sliding, and the inertia is used to continue driving. When the vehicle speed drops to medium speed, the oil is slightly added, and the high-speed gear is quickly changed to continue the acceleration. . (3) Sliding downhill. It is suitable for wide straight sections with undulating waves and steep slopes in hilly areas. First slam the slope at a higher speed and disengage it near the top of the slope so that the tractor crosses the top of the slope and continues to slide.
2, the use of economic speed and fuel economy. The tractor has a minimum fuel consumption rate, ie economic speed. Higher or lower than economic speed will increase fuel consumption. When driving above economic speed, the higher the speed, the greater the power required to overcome the driving resistance, the more fuel consumption; when driving below the economic speed, although the power required to overcome the driving resistance is small, the engine heat The loss increased and the fuel consumption increased. Different models travel on different loads and on different roads with different economic speeds. Good road surface, light load and high tractor performance. On the contrary, it is lower.
3, before driving, you should find out the driving route, avoid unnecessary walking, avoid the way to stop the road, because the start is more expensive.
4, the team travels to wait for the distance of the previous car to start again, do not keep too tight during driving, avoid walking and stopping.
5. When parking, choose a location that is easy to get started. Be optimistic about the position to drive carefully, reduce the number of forward and reverse, and try to be in place once.
6, mountain driving, when the short slope or through the undulating road, the slope should be accelerated in advance. When the slope is long, the gear should be shifted in time after the slope is slammed. Do not refuel, do not drag the gear, and change the low gear in time.
7. The tractor is trapped in the mud pit. When the wheels are slipping and idling, do not refuel and rush. You must repair the road or drive stones and planks under the wheels. Otherwise, not only does the fuel consumption increase, but the tractor is severely worn.
Second, do a good job of tractor maintenance in a timely and timely manner
The technical condition of the tractor has a great impact on the consumption of oil. Any increase in resistance and fever is a sign of increased power loss and increased fuel consumption. Therefore, the maintenance of the maintenance, lubrication, and adjustment, so that the internal resistance is reduced, you can save fuel. Mainly reflected in the following aspects:
1. Adjustment of ignition advance angle. The ignition advance angle is adjusted appropriately so that most of the mixture can be burned when the piston reaches the top dead center, and the maximum power can be obtained with the least fuel consumption. If the adjustment is not appropriate, it will consume more fuel.
2. Adjustment of the valve clearance. When the engine is in operation, the valve clearance changes due to the wear and tear of the valve, valve seat and other parts caused by the valve opening and closing. Therefore, inspections and adjustments must be made regularly. Otherwise, if the valve clearance is too large or too small, the engine power will decrease and the fuel consumption will increase. If the valve clearance is too large, the opening height of the valve will be reduced, the valve opening time will be shortened, the engine intake air amount will be reduced, the exhaust gas will be poor, and the exhaust gas will remain in the cylinder, so that the engine power is reduced and the fuel consumption is increased; When the valve clearance is too small or there is no gap, the valve will be closed tightly, causing air leakage, and the engine power will be reduced, and the fuel consumption will increase.
3. Clean or replace the filter element of the air filter in time. The blockage of the air filter will cause insufficient intake air, so that the oil can not be completely burned and increase the fuel consumption.
4. Timing, quantitatively adding the specified type of lubricating oil, grease and other oil materials, and timely cleaning or replacing the filter elements of the diesel and oil filter (or replacing the diesel filter and the oil filter assembly) to supply the tractor. It is well lubricated and works properly, reducing wear and oil consumption of the parts.
5. Lubrication and adjustment of hub bearings. Lubrication of the hub bearing, as long as the bearing is filled with grease, the hub cavity, only need to apply a thin layer of grease to prevent rust, otherwise the resistance will increase; the axial clearance adjustment of the bearing should be appropriate, too small will make The rolling resistance increases, and the wheel is skewed when it is too large. It is easy to sway during driving. Not only is the direction difficult to grasp, but also the brake drum slanting is in contact with the brake pad, which also increases the consumption of oil.
6, front beam adjustment. If the front beam is not accurate, the rolling resistance increases, and when the speed exceeds 30 km, the direction is difficult to control, and the speed is reduced, thus increasing the fuel consumption.
7. Adjust the foot brake clearance. If the gap is too small, the resistance increases and the fuel consumption increases. If the clearance is too large, the brake will not work, affecting safety, and the driver must prepare for braking at any time for safety, slow down the driving speed and increase the fuel consumption.
8. Adjustment of the clutch pedal free travel. If the free travel is too small, the clutch is easy to slip. In order to obtain the required travel speed, the engine speed needs to be increased, which causes a part of the power to be consumed in the unhelpful friction between the clutch parts, so that the fuel consumption is increased. The free travel is too large, the clutch is poorly separated, and the shift is difficult, which also increases the fuel consumption.
9. Adjustment of tire pressure. The tire pressure is low, the rolling resistance is increased, and the fuel consumption is increased; the tire pressure is high, and although the rolling resistance is reduced, the smoothness and handling of the tractor are affected. What the driver needs to do is to check the tire pressure frequently to keep it within the limits specified by the manufacturer.
Third, reasonable selection of mature fuel-saving agents
The fuel-saving agent is an additive that improves combustion and can be used in diesel fuel to produce a fuel-saving effect. There are many types of fuel-saving agents, and the fuel-saving effect is different. Some are obvious, some are not obvious. Fuel-saving agents generally can play the following three functions:
1. Catalysis. It can promote better atomization of fuel, improve the combustion process, fully burn the mixture, improve combustion efficiency, and thus save fuel.
2. Neutralization. Some components of the fuel-saving agent can be neutralized with sulfur dioxide and sulfur trioxide produced by the combustion of sulfur-containing compounds in the fuel, so that they are discharged into the gas, preventing the combination with other components in the cylinder to precipitate as coke or water to produce sulfurous acid. , sulfuric acid and corrosion of metals.
3. Cleansing effect. After using the fuel containing fuel-saving agent, the original carbon deposit of the cylinder can be softened, thinned or peeled off, so that new coke is no longer formed, and the combustion chamber, piston, valve, spark plug, etc. are kept clean, thus prolonging the engine. Maintenance cycle and service life.
