Many friends think about the fuel consumption of a car when buying a car. In addition to the cost of buying a car, the most expensive car maintenance in the later period is the fuel cost, so this has become the first consideration for the owner, then the fuel consumption of the car and What is the relationship? Is there any other reason besides the hardware equipment? The following is a brief introduction to the car fuel consumption in the end . 1, driving habits This is the acquired indicator that affects fuel consumption and is also an indicator of fuel consumption. The fuel consumption of the same car under different road conditions is different. It is not possible to open the air conditioner or even when the air conditioner is turned on, which affects the fuel consumption. Here, the small cylinder only talks roughly. 2. Urban road conditions In the urban area, it is often stop and go. When it comes to the morning and evening peaks, there is no such thing. In the big cities, the parking lot is basically closed, and the second and third tier cities are more and more blocked. In this case, try to maintain a constant speed. It is best not to step on the brakes after stepping on the accelerator pedal, and the damage caused to the car itself will also drain your fuel. When opening the air conditioner in winter and summer, don't drive to a large gear at once, and don't drive the air conditioner to drive the car. The correct way is: after the car starts, look at the water temperature gauge, wait until the temperature range of the vehicle is normal (the normal working temperature of the engine is between 90-120 degrees Celsius) and then turn on the air conditioner. This process feels very long and waits for the actual driving, that is, A minute of things. 3, often running high speed As long as you don't run at full speed and full speed, it is very beneficial to the car. At present, China's regulations stipulate high-speed speed limit of 120km / h, but often run high speed know that the actual speed is far greater than the specified speed. In terms of vehicle technical indicators, the conservative nature of 1.6 natural inspiratory displacement can be around 170km/h. However, once the speed value is exceeded, the fuel of the vehicle will increase greatly. When the speed is 90km/h, it is the most fuel-efficient (always, depending on the model), this time is very beneficial to the car. 4, the engine This is an innate indicator of fuel consumption. From the oldest carburetor to the current in-cylinder injection system, brands are working hard to improve the fuel economy of the engine. The previous article of the small cylinder has briefly introduced the two ways of fuel injection, so I won't go into details here. Interested friends can check the history of the public number "car small tank". From a technical point of view, direct injection in the cylinder is a very good technology, which greatly improves the fuel efficiency, but has high requirements for the engine fuel supply system and cylinder materials. 5, gearbox The gearbox here refers to the automatic gearbox. The engine and gearbox make up the simplest power output system, so the construction of the gearbox also directly affects fuel consumption. In the previous article, the small cylinder also introduced the working principle of some automatic transmissions. From the perspective of fuel consumption, the dual clutch transmission and the CVT continuously variable transmission are the most fuel-efficient. The torque converter transmission is relatively oil-efficient. Of course, this also It is related to the number of gears of the torque converter type. The more gears, the clearer the gear division. At different speeds, different gears can be used to match the fuel economy. Conversely, the fewer the gears, the more fuel. For example, the joint venture automatic transmission models of about 100,000 yuan on the market today are mostly four-speed hydraulic torque converter-type conventional transmissions except for the new Excelle. Although the transmission technology is mature enough (more than 30 years), it is somewhat outdated. . These are the related questions about the fuel consumption of the car that Beimai.com has summarized. What do you understand? The reasons for going out of your own engine are also human factors, so even if the car with small displacement is not the right way, It may cost a lot of oil money, so we will develop good driving habits as much as possible for our own pockets, and at the same time increase the service life of the car.
An infrared thermometer's advantage against a conventional probe thermometer is speed and the fact that it is non-contact; but keep in mind an infrared thermometer only measures the surface temperature. Infrared thermometers are easy to use, simply point the instrument at the object you wish to measure and read the temperature on the LCD.
