Fuel economy and reliability technologies are the most watched
Similar to sedans, today's commercial vehicle advertising has increasingly highlighted the selling point of technology. However, the reporter discovered through the advertisements of nearly 20 commercial vehicles that the outstanding technologies of commercial vehicles are somewhat different from those of cars, and they are more respected for the fuel economy and reliability of vehicles. They are “fuel-efficientâ€, “safe†and “reliableâ€. Other keywords have been mentioned frequently, involving most components in powertrains and safety configurations. In addition, there is a trend that is more obvious. In terms of driving comfort, commercial vehicles are developing toward saloons.
Powertrain is the key to energy saving
The most concern for commercial vehicle users is the power and economy of the vehicle. This is reflected in the components, which is the powertrain of commercial vehicles. As the heart of the car, the engine determines the dynamics and economy of the car and best reflects the entire vehicle technology level. In the models of the reporter’s statistics, the majority of advertisements involved engine technology.
In the respect of traditional diesel commercial vehicles, Shaanxi Automobile Delong F3000 hits “big horsepower, low fuel consumptionâ€, GAC Hino 700 series takes the “International Truck Fuel Contest Oil-saving Champion†as its propaganda focal point, and Dongfeng Tianjin DFL1160B2-KC9-002 is The "Cummins 190/210 hp engine with 7-speed transmission", "classic configuration, reliable and efficient" sign was played, and the famous "G-BOS Wisdom Operation System" was also placed prominently in the advertising space by Higer.
In recent years, natural gas engines have been increasingly used in the cargo and passenger transportation industries. Compared with fuel engines, users are more concerned about the energy-saving and emission-reduction performance of natural gas. Of the 14 commercial vehicles that were reported by reporters, 2 were LNG fuels, accounting for 14.3%. Among them, the joint truck LNG mixer has the characteristics of “a reduction of 93% of carbon monoxide, 33% of nitrogen oxides, and 50% of active hydrocarbon gas emissions compared to conventional vehicles, reaching the national IV and above emission standardsâ€, Hager 6 The advantages of energy-saving, high-efficiency, smart environmental protection and other advantages of the ~12-meter LNG road bus have also been revealed.
In addition, parts that are widely mentioned in commercial vehicle advertisements include transmissions, axles, and the like. Shaanxi Automobile DeLong F3000 claims to be “a paradigm for logistics and fuel conservationâ€. This is mainly due to its “big horsepower, low fuel consumption†engine, as well as transmissions, axles and other transmission systems. This car is fitted with Fastest center 10th/12th speed transmission, and Hande 13t MAN technology single-stage bridge and lightweight 425 single-stage bridge, small speed ratio design, new power transmission system calibration, powerful and more Fuel economy.
Multi-faceted protection is safe and reliable
In addition to energy conservation, commercial vehicle advertising also focuses on the safety and reliability of vehicles. For commercial vehicle users, the breakdown of a vehicle or a traffic accident will directly affect their work and income. Therefore, consumers place more emphasis on commercial vehicle reliability than cars.
“Because of the safety hazards associated with the accelerator pedal, Toyota’s large-scale recalls have suffered heavy losses. The commercial vehicle industry should pay sufficient attention to this problem. In the past two years, passenger car accidents caused a large number of casualties and truck accidents caused large-scale economic losses. Such cases are everywhere. Yes," an industry source told reporters.
Analysis of commercial vehicle advertising, the reporter found that in addition to the engine, chassis and body parts are the highest frequency of occurrence. The reporter learned that Wuzheng Aochi used a "double-layer welded frame, integrated stamping, riveting structure"; Shaanxi Automobile Delong F3000 cab uses laser seamless welding technology and rigid skeleton buffer structure, and as an exclusive domestic real through Europe "ECE-R29" strict crash test standard vehicle, its up to 55% braking efficiency of the WEVB braking system, a greater degree of protection of human and vehicle safety. The GAC Hino 700 series is equipped with safety devices such as front-mounted anti-submarine cab guards, beam front anti-bend design, and door anti-collision steel beams, to ensure the safety of drivers and others. Dongfeng New Dragon with front and rear drum brakes is more secure.
Safety is not only reflected in vehicle safety devices. In gas-fueled vehicles, safety is also reflected in gas tanks, gas cylinders and other devices. This point, the joint truck came to mind. “The safety test of the cans through gunshots, high-altitude crashes and fires has been carried out to ensure safety and reliability.†Believe to see such advertisements, consumers' doubts about the safety of the joint truck LNG mixer gas can be dispelled. Hager's 6- to 12-meter LNG road passenger coaches are also described in this advertisement.
In addition, the adoption of new technologies for braking systems and steering systems can also effectively improve the safety and reliability of vehicles.
Car-driven driving experience
Although commercial vehicles belong to production materials, the requirements for ride comfort of commercial vehicle users have gradually increased in recent years. This can also be seen from the advertisements. Advertising slogans emphasizing the driving experience of cars appear from time to time in advertisements for commercial vehicles.
Due to its use, passenger cars naturally value ride comfort, which has become a starting point for many bus companies to promote their products. When embarking on the promotion of its product CA6860LRD21 (8.6m road bus), the liberation bus highlighted the “innovation and improvement of interiors, large panoramic windows, and ergonomic seatsâ€; Nanjing Iveco Boldy has an integrated cruise system. , car-level air suspension.
Truck companies are also paying more and more attention to ride. For example, Hualing heavy trucks embody the humanized design, which will create a “home†feeling in the cab and give riders the feeling of driving a premium sedan. With the upgrade of standardization and modularization technology, the reliability of Dongfeng Xintianlong has been improved by more than 20%. However, the comfort of the Dongfeng New Tianlong has been greatly improved through airbag seats and suspension of the cab. Wuzheng Aochi 2000 also used its “car dashboard, canopy seats, car-level door guards, integrated headlights†as the highlight of the product's driving comfort.
It can be foreseen that with the gradual development of commercial vehicle products in China to high-end, the distribution of cars will become a factor that must be taken into account when commercial vehicle manufacturers develop products.
The color mixer can mix a variety of materials into a uniform mixture, such as cement, sand, crushed stone and water into wet concrete; It can also increase the contact surface area of materials to promote chemical reaction; It can also accelerate physical changes, such as adding solvent to granular solute, and accelerating dissolution and mixing through the action of mixing machinery.
Commonly used color mixers are divided into four categories: gas and low-viscosity liquid mixers, medium-high viscosity liquid and paste mixing machines, thermoplastic material mixers, and powder and granular solid material mixing machines. The gas and low viscosity liquid color mixing machine is characterized by simple structure, no rotating parts, small maintenance and low energy consumption. This type of mixing machinery is divided into four types: air flow mixing, pipe mixing, jet mixing and forced circulation mixing.
The color mixing machine of medium and high viscosity liquid and paste generally has strong shearing effect; Thermoplastic material mixer is mainly used for mixing thermoplastic materials (such as rubber and plastic) with additives; The mixing machines for powdery and granular solid materials are mostly intermittently operated, and also include machines with mixing and grinding functions, such as wheel rolling machines. During mixing, all materials involved in mixing shall be evenly distributed. The degree of mixing can be divided into three states: ideal mixing, random mixing and complete non-mixing. The mixing degree of various materials in the mixing machine depends on the proportion, physical state and characteristics of the materials to be mixed, as well as the type of mixing machine used and the duration of mixing operation.
The mixing of liquid mainly depends on the mechanical stirrer, air flow and the jet of the liquid to be mixed, so that the materials to be mixed are stirred to achieve uniform mixing. Stirring causes part of the liquid to flow, and the flowing liquid pushes the liquid around it, resulting in the formation of a circulating liquid flow in the solvent. The resulting diffusion between liquids is called the main body convection diffusion. When the liquid flow velocity caused by agitation is very high, there will be shear action at the interface between the high-speed liquid flow and the surrounding low-speed liquid flow, thus generating a large number of local vortices. These vortices spread rapidly around and bring more liquid into the vortex. The turbulent convection diffusion formed in a small range is called eddy diffusion.
The mixing mechanism of a small amount of insoluble powdery solid and liquid is different from the density component, and the mixing mechanism of immiscible liquid is the same, but stirring cannot change the particle size of powdery solid. If the settling velocity of solid particles cannot be less than the flow velocity of liquid before mixing, no matter what mixing method is used, it will not form a uniform suspension.
The mixing of different pastes is mainly to divide the materials to be mixed repeatedly and make them subject to the strong shearing effect caused by the actions of pressing, rolling, squeezing, etc., and then merge and knead repeatedly to reach the required mixing degree. This kind of mixing is difficult to achieve ideal mixing and can only achieve random mixing. The powdery solid is mixed with a small amount of liquid to form a paste, and its mixing mechanism is the same as that of paste material.
