According to the cooling medium used, engine cooling methods can be divided into water-cooled and air-cooled.
1. Water-cooled one by one with water as the cooling medium, heat first from the machine to water, by the flow of water to heat away and then into the atmosphere. After heat dissipation, the water flows back to the hot part again. The normal working temperature of the engine can be maintained by properly adjusting the water and cooling intensity. At the same time, hot water can also be used to preheat the engine, which is convenient for starting in winter.
The structure of water-cooled cooling system: water pump, radiator, fan, thermostat, expansion tank, warm air, engine water jacket, cooling pipe.
2. the heat of air-cooled parts is directly scattered into the atmosphere.
At present, most of the cars are water-cooled.

Well-known companies in the United States and South Korea cooperate to develop lithium-metal batteries with twice the energy density and cycle life.By Erica Zhu Feilong Jiangli
Chongqing Feilong Jiangli collects the latest information for you, so that you can get the most cutting-edge technical information. A private company focused on developing the first rechargeable lithium-metal batteries in the United States announced that it would cooperate with SKI, Korea's largest energy and chemical company, to develop lithium-metal batteries.
This cooperation will focus on solid-state lithium anode laminates, which can double the energy density and cycle life of rechargeable batteries. The initial goal was to produce and test prototype batteries to prove whether the increase in volume and weight led to an increase in energy density and cycle life relative to existing lithium-ion batteries.
SK Innovation plans to complete the research on conductive glass separators by the end of 2021 and apply them to the development of lithium metal batteries. Conductive glass separator is the key technology to promote the stability of lithium metal batteries. The company hopes to successfully develop conductive glass separators to accelerate the commercialization of lithium-metal batteries.
A battery company based in Berkeley, California, USA, has invented and patented a technology to protect the electrodes of lithium-metal batteries, which is the core technology of sulfur-lithium batteries, lithium-air batteries and water-lithium batteries. Scientists at the battery company have invented a patented process that combines lithium metal with a continuous monolithic glass electrolyte. Battery validation in the laboratory indicates that continuous monolithic glass prevents dendrites and promotes lithium metal recycling.

Although positioned in the concept car, the Ford Ranger Storm is still based on the concept of the current Ford Ranger by adding kits. Ford's move is naturally considered for the aftermarket in South America. In appearance, the new Ford Ranger Storm concept car is fitted with Pirelli's MTR Scorpion all-terrain tires, matching 17-inch aluminum alloy wheels. After upgrading the tires, the vehicle posture of the new Ford Ranger Storm concept car has been significantly improved. However, in terms of chassis, the Ford Ranger Storm concept car did not upgrade the suspension system, still retaining the configuration of the regular version.
In terms of appearance, the Ford Ranger Storm concept car is optimized for link hidden, please login to view. The intake grille uses a letter grille that is similar to the US version of the Ranger Raptor, but the letters on the grille become Storm. And embellished with silver highlights. The fog lamp trim cover on both sides of the front bumper adjusts the form of the fog lamp and is composed of two LED light sources. A silver shield is added to the front bumper to embellish it. In terms of the kit, the Ranger Storm concept car adds a roof rack to the roof of the gantry, and the right fender adds an additional wading throat.
The overall color of the car is dominated by two colors of orange and black. The black cross-country protection kit wraps the area under the cab, while the position of the container changes to the main color. This style of creation is very different from the Raptor version of the North American market.
In terms of power, the Ford Ranger Storm concept car is powered by a 3.2-liter inline five-cylinder diesel engine with a maximum output of 200 hp and a maximum torque of 470 N·m. It is matched with a six-speed automatic transmission and a four-wheel drive system.

Special casting has the characteristics of high precision, good mechanical properties, high productivity and good working conditions.
Special casting methods are as follows:
(1) Metal mold casting: the method of injecting liquid metal into a mold made of metal to obtain a casting.
Features: One mold multi-casting, high casting accuracy, good mechanical properties, but high cost, mainly used for mass production of copper, aluminum, magnesium and other non-ferrous alloy castings.
(2) Investment casting: a casting method in which wax is made into a pattern, coated with several layers of refractory paint, and heated to make the pattern melt, flow out, and bake into a pattern with a certain strength, then poured and removed.
Process features: take the melting pattern as the starting mode. The precision of casting is high, and it is a method of little cutting. Its equipment is simple and production quantity is not restricted. It is mainly used for mass production and mass production. The drawback is that the process is complex and the production cycle is long.
(3) Pressure casting: a casting process in which molten metal is rapidly pressed into the cavity of a metal mold under high pressure and solidified under pressure to obtain a casting.
Process features: high speed and high pressure is applied on the basis of metal mold casting to improve metal fluidity. It is mostly used for mass production of precision casting of non-ferrous alloys, such as aluminum, copper and magnesium.
(4) Centrifugal casting: a casting method in which molten metal is poured into a high-speed rotating mold to solidify the liquid metal under the action of centrifugal force.
Process features: compact structure, good casting quality. It is used to produce hollow castings.

When selecting parts for a car repair, it pays to know the differences between original and aftermarket parts. Whenever possible, get estimates for both.
Choosing between original and aftermarket car parts — and even used parts of either type — is all about squaring your priorities with your budget.
You’ll have different options depending on the part and the shop. And the best choice will depend on whether you’re trying to keep repairs cheap, restore your car’s appearance after a wreck or soup up your ride.
Original equipment manufacturer (OEM) parts match those that came with your car, and are of the same quality as its original parts. They’re also the most expensive.
