Although the previous generation of light commercial vehicles had several engine power ratings for a single brand, that was the result of the use of different displacement engines. The new generation of light commercial vehicles is to maintain the engine's displacement as much as possible, and changes are achieved through the use of single-stage and two-stage supercharging. For example, the Mercedes-Benz Sprinter uses a displacement of 2.2 L diesel engine, a total of 65kW, 80kW, 95kW and 110kW four power levels. The 65kW model uses an exhaust-relief valve booster, and the 80kW model uses a variable booster VGT with variable-section system VGS. The 95kW and 110kW models use two-stage supercharging with superchargers of different sizes to minimize the production cost of the engine. Volkswagen's new Crafter light commercial vehicle is also equipped with a five-cylinder diesel engine with a displacement of 2.5L and a power rating of 65kW, 80kW, 100kW and 120kW respectively. The method of changing power is the same as that of Mercedes-Benz.
In conventional slat-type trucks, since the floor of the cargo box is above the plane of the frame, the wheel cover of the slat-type truck is always under the floor of the cargo box, while the wheel cover of the new-generation van is convex. Out of the compartment. Obviously, the loading and unloading height of traditional slat-type trucks is much higher than that of new-type vans. Therefore, in the case of the same loading area and loading volume, the new type of truck is not only easy to load and unload cargo but also has a reduced center of gravity when fully loaded, which is very important for driving safety.
The next-generation van trucks generally use the split back door (the so-called Guanyin), and the back door of the Mercedes-Benz Lingte van can open 270°. The sliding doors on the right or left and right sides of the cargo hold are wide and high, and vary depending on the length and height of the cargo hold. The width of the sliding door entrance reaches 1260mm or 1510mm, and the height reaches 1885mm or 2175mm. The occupants do not have to stoop in and out, but can also move upright in the cargo compartment to load and unload cargo.
According to the requirements of EU safety regulations, vans must pass the braking and loading safety tests when a collision occurs. There are three main principles for safe loading of vans:
First, when loading cargo, it is necessary to pay attention to the left and right symmetrical configuration. If there are fixed partitions in the cargo hold, the cargo should be arranged in the middle of the cargo hold.
The second is that if there are no fixed partitions in the cargo hold, the goods should first be placed in the middle of the cargo hold and then be fixed with tensioning straps or ropes.
Third, the longitudinal configuration of the cargo in the cargo hold should be based on the load distribution.
In order to improve loading safety and handling efficiency, a new generation of vans are equipped with a variety of devices for fast and secure loading and unloading. There is a separation wall between the cab and the cargo compartment, as well as fixed or pullable windows and sliding doors, to ensure that the driver will not be stored at the rear when the vehicle is under various driving conditions, especially when a collision occurs. Damage and can monitor the status of the cargo. In addition, along the cargo floor, there are more than a dozen rope retaining rings and a fixed lock ring chute. Similar snap rings are also used on each side post. For some bulk cargo, you can use a special net covered in the car.
Another advantage of vans is that they can be transported around the clock and can effectively prevent plagiarism.
