Hydraulic hybrid bus came out in Shanghai

Recently, a hydraulic hybrid bus (HHV) with high fuel economy and high emission reduction capability developed by Shanghai Jiaotong University Shenzhou Automobile Design and Development Co., Ltd. was launched. It is reported that this kind of bus can save more than 25% energy in urban bus conditions, and can reduce black smoke and other emissions by more than 35%, whether it is a traditional energy bus fueled by diesel or gasoline, or dimethyl ether or ethanol. New energy buses, such as biodiesel and electric energy, can be retrofitted, and are energy-saving and emission-reducing buses that are easy to promote.

From the technical point of view, the hydraulic hybrid bus is a technology that recovers the braking energy of the bus frequently braked by the hydraulic power system, and then uses the recovered energy to drive the bus to start and accelerate. Getting started is the most fuel-intensive phase of the bus. If the energy recovered by the brakes is used in the starting and acceleration stages, it will save energy. Take the diesel bus with a length of 11 meters and a total weight of 15 tons as an example. The average recovery of 20 ml of diesel oil per brake is 1000 times per day, which can save 7,000 liters of diesel per year. The most important stages of bus emissions are the parking idle speed and the low start phase. The hydraulic hybrid bus's start-up and low-speed engines can not be driven. The engine can be automatically turned off when the vehicle is idling, thus eliminating or greatly reducing the black smoke and other emissions during start-up, acceleration and parking idling. %.

The first difference with other types of new energy vehicles is that hydraulic hybrid buses can be installed not only on new cars, but also on existing vehicles. After installation, the structure and performance of the original buses are not changed. The second difference with other types of new energy vehicles is that there is an independent engine drive mode, which is driven by the performance and power of the original bus; there is also an alternate driving mode of engine power and hydraulic power, with the performance of the hydraulic hybrid bus. Power driving. Therefore, hydraulic hybrid buses are not only equipped with new buses with an annual growth of 50,000, but also active buses with a capacity of 350,000. The energy-saving and emission-reducing performance of most active buses in China is not up to standard, and more than 200 billion yuan has been completely completed. Since the cost of installing the hydraulic hybrid system is not more than 70,000 yuan, the emission reduction and energy-saving performance of the original bus can reach the Euro III or Euro IV standard, which is favored by the active bus. The third difference with other types of new energy vehicles is that many new energy vehicles require supporting ground facilities, including funding, site and safety issues, such as alcohol, ether fuel vehicles, gas stations, biodiesel. Fuel-fueled vehicles require gas stations, hydrogen-fueled vehicles need hydrogen refueling stations, electric vehicles need charging stations, etc., while hydraulic hybrid buses do not need to increase ground facilities, and there are no related problems.

Sleeping Gear

A good night's sleep is a key element to a great outdoor experience
We are often asked, "Is it cold to camp outdoors, especially in winter, sometimes in the snow?" "What brand and
model of Sleeping Bag do you have and what is the temperature limit?" This is a very difficult question to answer,
as there are many factors that can affect sleep at night in outdoor camping.

1. choice of campsite, and what to sleep on?
The location of the campsite is key to choosing, flat, sheltered from the wind, and dry - uneven ground directly
affects the sleeping body, even if you are using an air mattress try to find a flat surface.
When camping outdoors, blowing wind can take away body temperature and it can make the outdoor environment
very noisy, so it is also important to choose a campsite that is sheltered from the wind.

2. selection of sleeping gear
In some tests, researchers have found that heat loss through the ground is three times greater than heat loss
through the air. Poor-quality pads can make an expensive sleeping bag feel more or less useless, while a good
sleeping pad may improve the quality of your sleep. A good sleeping pad will keep you comfortable on the
uneven ground of a worse campsite, while also providing a key barrier against heat loss.

3. Keep your sleeping environment dry
What protection do you have to keep you and your sleeping bag dry and windproof?
Where do you sleep, a hut, a tent, a snow cave, or an alpine hut? All of these can affect your sleep. Staying
dry is not only about protecting yourself from precipitation, but it is equally important to deal with condensation.
If your sleeping bag gets damp, try to dry it out in the sun or build a fire to dry it out before you go to bed.

As a professional supplier of camping outdoor products, we are committed to bringing our customers a great
outdoor experience and high-longevity outdoor sleeping products, and we look forward to working with you
in the future.
