Noise pollution, along with air pollution, water pollution, and solid waste pollution, is known as the four major environmental hazards. In order to raise awareness of the dangers of noise and the dangers of this "invisible killer", April 16 has been designated as "World Noise Day" every year since 2003. Noise is the enemy of mankind, do you know about noise and its dangers, do you suffer from noise, do you know how to prevent it?
There are many types of noise, including industrial noise, traffic noise, construction noise, living noise, etc. According to the World Health Organization's report on the burden of disease caused by noise pollution, noise has become the second cause of death to human public health after air pollution. Noise not only interferes with sleep and normal work and life, but also causes hearing and vision impairment, as well as neurological and cardiovascular diseases. In order to reduce the harm of noise, people have taken a variety of protective measures, such as wearing protective tools, placing green plants to absorb sound waves, and installing soundproof windows. However, it is impossible to avoid noise through the above protective measures in an outdoor environment, especially when driving a vehicle with poor quiet performance, the noise generated by the vehicle itself is already unbearable, and it is difficult to isolate the noisy sound from the outside world, which seriously affects the travel experience.
6 noise reduction technologies to solve the noise problem
SINOTRUK pickup truck is well aware of the troubles and hazards caused by noise to users, starting from the two aspects of engine noise reduction and vehicle noise reduction, using 6 major sound insulation and noise reduction technologies to reduce noise in an all-round way.
Submarine deep-sea silence technology. SINOTRUK pickup truck is equipped with Weichai WP2H 2.0T diesel engine, original submarine deep-sea silent technology, and the engine adopts hydraulic mounting, which effectively reduces the noise and vibration transmitted to the body and overcomes the stubborn problem of high noise of diesel engine.
Passenger car grade seal design. The body of the vehicle is spliced by many sheet metal parts, which will leave gaps and holes, becoming a channel for gas and noise to enter the cockpit, and SINOTRUK pickup trucks adopt a passenger car-grade seal design, and the gas leakage of the whole vehicle is ≤ 50SCFM, which effectively improves the noise reduction performance.
Soundproof carpets. Conventional carpet can not produce a good sound insulation effect, China National Heavy Duty Truck pickup truck adopts 1mm EVA composite carpet, which effectively reduces and eliminates the noise during driving, and the tire noise and road noise control effect is better.
Two-component sound-absorbing cotton. Installing sound-absorbing cotton in doors, windows, hoods and other noise-prone locations is also an important way to reduce noise, and SINOTRUK pickup trucks use 600g/㎡ two-component sound-absorbing cotton, which has a better high-frequency noise isolation effect than competing 300g/㎡ sound-absorbing cotton.
Thickened soundproof glass. In order to further isolate the external noise, the front row of the SINOTRUK pickup truck adopts 4mm+ acoustic laminated glass, which reduces the noise of high-speed driving by 5 decibels compared with the conventional 3.5mm ordinary tempered glass.
Professional NVH tuning technology. In addition to the use of a variety of sound insulation materials, engineers also identify the source and generation mode of noise, and carry out special adjustment and optimization to suppress noise and vibration, to ensure that the pickup truck can maintain good quiet performance under different driving conditions.
After the use of multiple acoustic sound insulation technology, the idle noise of SINOTRUK pickup truck ≤ 41 decibels, which is close to the noise of refrigerator operation, and the noise at a constant speed is 51-62 decibels, which is 4-6 decibels lower than that of models of the same level, and the mute level is comparable to that of gasoline vehicles. SINOTRUK pickup truck creates a quieter, smoother and more comfortable driving experience for users, avoids noise interference to drivers, improves driving safety, and avoids potential harm to users' bodies caused by noise.
3 subdivided models, opening up a multi-faceted car use scene
The lifting of policy bans and consumption upgrades have promoted pickup trucks to enter thousands of cities, and pickup trucks, as multi-purpose universal models, are more and more loved and respected by people. SINOTRUK Pickup has launched three models: off-road, passenger and commercial to meet the needs of users for outdoor leisure, fashionable life, entrepreneurship and wealth creation, and is committed to becoming the first choice for users to travel with high quality. The whole series of SINOTRUK pickup trucks is equipped with Weichai Power's WP2H 2.0T diesel engine, with a maximum power of 140kW and a peak torque of 420Nm, which adapts to the power needs of all scenarios and multiple fields.
The off-road pickup truck is equipped with a 2.0T+8AT power system, with three differential locks in the front, middle and rear, K-MAN nitrogen shock absorber, 10,000 pounds electric winch (optional 12,500 pounds), 700mm wading hose, full vehicle chassis armor, tank U-turn, creep mode and other equipment; BorgWarner timely four-wheel drive system provides 7 modes of all-terrain management system to bring all-terrain off-road performance; equipped with L2.5+ high-end intelligent driving assistance system, 360 surround view +Transparent chassis, let the off-road as you like.
If the off-road pickup truck is a trustworthy partner for users to carry out off-road activities, the passenger pickup truck is the best choice for users to improve the quality of travel. There are up to 14 intelligent assisted driving functions for passenger pickups, covering all daily car use scenarios, and using technology to protect safety in an all-round way. It adopts high-end configurations such as 12.3-inch central control screen + LCD instrument, voice recognition function, intelligent car networking system, dual-zone automatic air conditioning, ACC adaptive cruise, etc., and further advanced luxury and intelligence, helping users enjoy a comfortable passenger car-level pickup life.
In addition to providing users with ideal choices in the two major fields of off-road and passenger, SINOTRUK pickup trucks have also made breakthroughs in commercial pickups. SINOTRUK pickup commercial models have two models: long axle and standard axle, with a cargo box size of 1800/1520*1520*530mm, with rear leaf spring suspension and high-strength frame, bringing stronger carrying capacity. After satisfying the user's cargo needs, the commercial pickup truck also has a 12.3-inch central control screen, equipped with high-end equipment such as vehicle-machine mobile phone interconnection, dual-zone automatic air conditioning, keyless entry, and one-button start, equipped with Bosch ESP9.3 body stability system, and 6 intelligent driving assistance functions. Commercial pickup trucks are closer to passenger cars in terms of configuration, reversing the image of low-end tool carts of pickup trucks, whether it is cargo transportation or daily travel, allowing users to have a face.
SINOTRUK pickup truck solves the fundamental problem of excessive noise of diesel pickup trucks with advanced sound insulation and noise reduction technology, allowing users to have a quiet driving space comparable to high-end passenger cars. With nearly 100 years of experience accumulation and technical reserves of SINOTRUK, it has launched a large-scale pickup truck in all fields, which is suitable for off-road, passenger and commercial scenarios, bringing users a smarter, more high-end and safer driving experience, and unlocking the infinite possibilities of pickup trucks.
