开车习惯导致汽车油耗高
Driving habits lead to high fuel consumption
城市里开车，经常会遇到堵车，堵车时油耗的增加是我们无法避免的，但平时的开车习惯也至关重要。有的车友呢，每次起步时都是大脚油门，正常行驶时中，也是油门忽高忽地，这都会影响油耗的增加，所以平时各位车友都要养成良好的开车习惯。还有一些小细节需要注意，有些车冬天打开暖风以后，A/C开关也会自动打开，压缩机不知不觉就就运转了起来，所以记得关掉A/C开关
When driving in cities, we often encounter traffic jams. The increase of fuel consumption in traffic jams is inevitable, but the usual driving habits are also very important. Some riders start with a big foot throttle every time. During normal driving, the throttle is also high and low, which will affect the increase of fuel consumption. Therefore, at ordinary times, all riders should develop good driving habits. There are also some small details to pay attention to. After turning on the warm air in winter, the A / C switch will be turned on automatically, and the compressor will run unconsciously, so remember to turn off the A / C switch
发动机积碳导致汽车油耗高
Engine carbon deposition leads to high fuel consumption
发动机进气和燃油系统的积碳也对车辆油耗的增加有很大的影响。比如节气门，节气门是控制发动机的进气量的，发动机喷油量是由发动机电脑按照进气量的多少来计算的，节气门也是由油门踏板来控制的，如果节气门脏了，油门踏板就必须控制它增加进气量来维持正常需求，进气量和喷油量都增加，油耗当然也会增加。
The carbon deposition of engine intake and fuel system also has a great impact on the increase of vehicle fuel consumption. For example, the throttle valve controls the intake volume of the engine. The engine fuel injection volume is calculated by the engine computer according to the intake volume. The throttle valve is also controlled by the accelerator pedal. If the throttle valve is dirty, the accelerator pedal must control it to increase the intake volume to maintain normal demand. The intake volume and fuel injection volume will increase, and the fuel consumption will certainly increase.
火花塞故障导致汽车油耗高
High fuel consumption caused by spark plug failure
火花塞每3万公里不及时更换会增加油耗。火花塞的作用就是点燃发动机的混合气体，它在发动机的高温和高压环境里，加上内部积碳的影响，性能就会逐渐降低，这就会使燃烧室的点火不准确，从而使发动机燃烧效率降低、油耗增加。
If the spark plug is not replaced every 30000 km, it will increase fuel consumption. The function of the spark plug is to ignite the mixed gas of the engine. In the high-temperature and high-pressure environment of the engine, coupled with the influence of internal carbon deposition, its performance will gradually reduce, which will make the ignition of the combustion chamber inaccurate, so as to reduce the combustion efficiency and increase the fuel consumption of the engine.
氧传感器故障导致汽车油耗高
High fuel consumption caused by oxygen sensor failure
前氧传感器出现故障时会导致油耗增加。氧传感器分为前氧传感器和后氧传感器，前氧传感器的位置是在排气歧管处，顾名思义，它的作用是检测氧气含量的（油气混合物燃烧完成后的），发动机电脑根据它检测的氧气含量来调节是否增加喷油量，所以当前氧传感器出现故障时，发动机电脑ECU无法得到正确的信号，导致油耗增加。
Failure of the front oxygen sensor will increase fuel consumption. The oxygen sensor is divided into front oxygen sensor and rear oxygen sensor. The position of the front oxygen sensor is at the exhaust manifold. As the name suggests, its function is to detect the oxygen content (after the combustion of oil-gas mixture). The engine computer adjusts whether to increase the fuel injection amount according to the oxygen content detected by it. Therefore, when the current oxygen sensor fails, The engine computer ECU cannot get the correct signal, resulting in increased fuel consumption.
空滤脏了导致汽车油耗高
The air filter is dirty, resulting in high fuel consumption of the car
不按时的保养也会导致油耗增加。空滤每1万公里更换一次，空滤更换不及时，过滤效果就会变得很差，发动机进气困难，进而导致汽油和空气不能充分的混合，车辆的动力也会有明显的下降，时间久了当然也会增加油耗。
Untimely maintenance will also lead to increased fuel consumption. The air filter is replaced every 10000 kilometers. If the air filter is not replaced in time, the filtering effect will become very poor, the engine air intake will be difficult, resulting in the insufficient mixing of gasoline and air, and the power of the vehicle will decline significantly. Of course, the fuel consumption will increase over time.
轮胎气压低导致汽车油耗高
Low tire pressure leads to high fuel consumption
轮胎气压低会增加油耗。轮胎胎压低时或者更换更宽、更大尺寸的非原厂轮胎后，轮胎与地面之间的接触面积变大，肯定也会增加正常行驶时的摩擦力和油耗。
Low tire pressure will increase fuel consumption. When the tire pressure is low or after replacing a wider and larger non original tire, the contact area between the tire and the ground becomes larger, which will certainly increase the friction and fuel consumption during normal driving.
上面这些问题不注意都会导致油耗增加，气温高低影响导致油耗波动，车辆长时间不做保养，机油和空气滤芯变脏也会导致油耗增加的原因，火花塞高压包的问题，气压不足，某些电路问题，传感器数据，水温传感器，积碳等都会影响油耗增加。
The above problems will lead to increased fuel consumption if you don't pay attention to them. The high and low temperature will lead to fluctuations in fuel consumption. The reasons for the increase in fuel consumption will also be caused by the vehicle's long-term lack of maintenance and the dirty oil and air filter element. The problems of spark plug high-voltage package, insufficient air pressure, some circuit problems, sensor data, water temperature sensor, carbon deposition, etc. will all affect the increase in fuel consumption.
