What are the factors that affect the fuel consumption of concrete mixer trucks?

In the operating cost of concrete enterprises, the proportion of fuel consumption of concrete mixer trucks is as high as 53%. How to reduce fuel consumption has become an urgent problem for enterprise managers to improve. In this regard, the tank car sales manufacturers have made a detailed introduction to the important factors affecting fuel consumption, hoping to help you better.

Factors affecting the fuel consumption of concrete mixer trucks:

The fuel economy factor of the mixer truck 1: The use of the mixer truck 

The main factors affecting the fuel economy in terms of use are to keep the technical condition of the concrete mixer truck in good condition and the correct driving operation. Mainly as follows:

a. Correct technical maintenance and adjustment

The adjustment and maintenance of the mixer truck will affect the performance of the engine and the driving resistance of the mixer truck, and have a considerable impact on the fuel consumption per 100 kilometers. Therefore, the correct technical maintenance and adjustment will have a great impact on the fuel economy of the mixer truck.

First of all, keep the engine in good technical condition. Maintain and inspect the oil supply system, air intake system and lubrication system to prevent oil leakage, and timely check the precipitation and impurities in the filter. When the air filter is not smooth, the fuel consumption will increase by about 3%. "Three filters" for maintenance to maintain the correct temperature of the engine cooling system.

In terms of chassis, it is necessary to strengthen the maintenance and adjustment of each assembly to maintain proper sliding ability and reduce fuel consumption. The sliding ability of the cement tanker is often evaluated by the sliding distance, and the sliding distance can be used to check the technical condition of the chassis.

The positioning of the front wheel of the mixer truck, the adjustment of the gap of the brake, the tire pressure, the tightness of each bearing, the clearance of the moving friction part and the lubrication quality will have a great impact on the movement resistance of the mixer truck, and must be adjusted and maintained according to regulations.

b. Driving operation technique

Correct driving practices can greatly reduce the fuel consumption of a car. When other conditions are the same, fuel consumption can be reduced by about 10% due to economical and reasonable driving. The reason is whether the driver can adopt suitable driving operations according to the operating conditions of the mixer truck, so that the man-machine can be properly coordinated and the mixer truck can be achieved. good operation. Therefore, reasonable driving operation has a great effect on fuel saving.

Early braking: Take your foot off the accelerator in advance, and then use the car's own freewheeling. If your car is manually shifting, keep it in gear until the car is stationary.

Shorten upshift time. If the car is on automatic transmission, lightly press the gas pedal to quickly move the transmission into high gear; the harder you apply, the longer the car will be in low gear. If the vehicle is mechanically shifting, it should be shifted from the low-speed driving state and continuously shifted to the high-speed gear as soon as possible.

When conditions permit, keep in the high-speed gear of the transmission and drive at a relatively small throttle (the engine runs at medium speed), and avoid frequent braking as much as possible, preferably less braking.

When driving at a steady speed, try to avoid unnecessary use of the accelerator to ensure that the speed and your pressure on the accelerator are balanced. Maintain a comfortable driving position, and once you reach a steady speed, relax your foot on the accelerator to maintain a steady supply of fuel.

c. Reasonable organization of transportation

When using concrete mixer trucks, it is necessary to give full play to the subjective enthusiasm of the transportation staff and take advanced measures to reduce the fuel consumption of the unit transportation work.

Factors Affecting the Fuel Economy of Concrete Mixer Truck 2: The Structure of the Mixer Truck 

The following factors affect the fuel economy of the mixer truck.

a. Size and quality of mixer truck

The increase in size and mass of the car increases rolling resistance, air resistance, hill resistance and acceleration resistance. The mass utilization factor of the mixer truck affects the fuel economy. Compared with the quality of the vehicle equipment. The larger the quality utilization coefficient, the higher the proportion of effective transportation quality, and the lower unit fuel consumption and cost in transportation. With the improvement of production technology level, the quality utilization coefficient is gradually increasing.

b. Engine

The engine is the component that has an impact on fuel economy. The influencing factors mainly include compression ratio, fuel supply, power utilization and so on.

The higher the engine compression ratio, the higher its effective efficiency. Therefore, by increasing the compression ratio within the allowable range, the fuel economy of the car can be obtained. The power and utilization of the engine have a great impact on fuel economy. Generally, the engine is in the load range of 60% to 80%, and the economy is high. In addition, the use of electronic computer control technology, such as electronic injection technology, will further improve fuel economy.

c. Drive train

The impact of the mixer drive train on fuel consumption depends on the drive train efficiency, the number of transmission gears and the gear ratio. The higher the efficiency of the drive train, the less energy is lost to the drive train, so the fuel economy The smaller the transmission ratio of the drive train, the better the fuel economy of the mixer truck. Now mixer trucks often use overdrive gears, which can reduce the total transmission ratio of the drive train. Using overdrive gears under good road conditions can make good use of engine power and improve vehicle fuel economy.

The number of gears of the transmission is increased, so that the engine is often kept working under the economical working condition. When the gear number of the transmission is the lower limit, it is a continuously variable transmission. When a continuously variable transmission is used, it provides the possibility to make the engine work under economic conditions under any conditions. If the continuously variable transmission can maintain a high mechanical efficiency, the fuel economy of the mixer truck will be significantly improved.

d. Concrete mixer truck shape and tires

The shape of the mixer truck has an impact on the fuel economy, mainly in the air resistance at high speed. Therefore, the body is streamlined and the air resistance coefficient is reduced, which can improve fuel economy, but in urban areas, due to the low driving speed, it has less impact on fuel consumption.

The above is the relevant introduction about the factors affecting the fuel consumption of concrete mixer trucks. Only by knowing these influencing factors can we better reduce its fuel consumption and improve the service life of the vehicle.
