3 Steps to Master LNG Truck Driving Skills

Proficient in LNG truck driving technology is the premise of energy-saving driving. The same model has basically the same conditions of use, and different people drive, the truck consumption can vary by more than 10%. LNG truck drivers need to be able to use various actions freely and correctly from starting, shifting, steering, braking, decelerating, parking and other actions. Then I will introduce the correct driving method of LNG trucks for you. I hope this article can help drivers and friends.


Step 1: LNG Truck Warm Up Start

When the LNG truck is started, it is necessary to give the truck enough warm-up time. If the engine temperature is too low, the LNG truck vaporizer cannot vaporize liquid natural gas into gaseous natural gas through the water temperature, resulting in poor atomization of the mixture and increased fuel consumption; at the same time, the temperature is low. If the oil viscosity is high, the resistance will also increase the fuel consumption. The best way is to preheat for a period of time (the water temperature is above 60°C), and then drive for a while at low speed, so that the truck can reach enough temperature and reduce unnecessary wear and tear of the engine.

It is most suitable to keep the engine cooling water temperature at 80-90 ℃ during the driving of the LNG truck. The normal engine water temperature is conducive to the gasification of liquid natural gas and the even distribution of the mixture, which makes the engine have good fuel economy and power, and ensures the viscosity and lubricating ability of the oil, and reduces the wear of the engine. Too high or too low temperature is not conducive to energy-saving driving.


Step 2: LNG Truck Starts Smoothly

LNG trucks are also divided into manual transmission and automatic transmission. Their starting methods are different. Here we will explain them to you respectively.

First up is a manual transmission LNG truck

When the manual transmission LNG truck starts, it is necessary to coordinate the operation of the hands and feet, lightly step on the accelerator pedal, and slowly lift the clutch pedal, so that the engine will not turn off, but also save energy, and realize the smooth start of the car. Starting too fast consumes 60% more fuel than a smooth start.

Starting method of automatic transmission LNG truck

The automatic transmission LNG truck starts, first apply the parking brake lever, and put the shift lever in the "N" position. Depress the brake pedal, start the engine, and engage the "D" gear. When you feel the car vibrate slightly, just release the parking brake lever, release the brake pedal, and the truck will start slowly. Note that when an automatic transmission LNG truck slams on the accelerator pedal, it will not immediately increase the speed of the truck, but will increase the fuel consumption.

Step 3: Reasonable braking

During the driving process of LNG trucks, braking is inevitable. Whether the driver can use the brake correctly not only affects the fuel consumption, but also affects the driving safety.

1. Engine braking

Engine braking is a braking method in which the driver releases the accelerator pedal after discovering the situation, reduces the engine speed, and uses the engine drag to reduce the speed of the LNG truck while the truck is running. The lower the gear, the greater the traction and the stronger the braking. The use of engine braking not only reduces the burden on the wheel brakes, but also saves consumption.

2. Predictive braking

Predictive braking refers to the driver's preparation in advance of thought and technology for changes in traffic conditions such as road conditions, pedestrians, cars and other traffic conditions that he has seen during driving, or anticipated complex situations that may arise, in a planned and purposeful manner. grounded deceleration and stop measures. Predictive braking can not only ensure the safety of trucks, but also save fuel and reduce losses. It is the most commonly used and effective method in driving.

3. Emergency braking

Emergency braking is the braking method adopted by the driver to quickly and advantageously depress the brake pedal when the truck is suddenly encountering an unexpected dangerous situation, so that the vehicle can quickly stop within the shortest distance. Emergency braking is detrimental to energy saving, mechanical wear and tire wear. Therefore, emergency braking should only be used as a last resort.


Through the LNG truck driving skills introduced above, you should have a certain understanding of truck driving. On the way of driving and transporting goods, the situations encountered are ever-changing. Vehicles on the road, the flow of people, road conditions, climate conditions, etc. are constantly changing. Drivers should be able to make correct judgments and actions based on changes anytime and anywhere, control the speed and temperature of the vehicle, reduce unfavorable factors, and use favorable conditions to make the car use less fuel and reduce the consumption of 100 kilometers.
