Why does the car shake when the air conditioner is turned on?
Spark plugs with carbon deposits;
After the vehicle is used for a period of time, the spark plug will accumulate carbon. If it is not cleaned in time, the engine output torque will become smaller and the on-air adjustment will shake. Soak the spark plug in a container filled with white vinegar for 2-3 hours, or 4-5 hours in severe cases. Then, find a hard brush and brush it a few times, and the carbon deposit will fall off. Then clean it with gasoline and dry it naturally for a period of time.
Carbon deposit on intake valve:
Generally, the normal cylinder pressure of older cars is 10.5, and now cars are all above 1 1 or above 12. If the cylinder pressure is abnormal, the computer on the vehicle will judge that the cylinder is on fire and automatically cut off the oil supply, which will cause the vehicle to shake when starting until it cannot be started. Abnormal cylinder pressure can be solved by cleaning the valve carbon deposit and operating the high-speed combustion cylinder at a speed of more than 4000 rpm. After removing the intake manifold, clean the intake valve by hand or by soaking in cleaning medicine.
Do not pay attention to oil:
The oil number represents the octane number and antiknock index of the fuel. Advanced fuel can prolong the service life of three-way catalytic converter and reduce emissions. In addition, different compression ratios of engines have different requirements for fuel quality. If the wrong gasoline is used, there will be serious engine carbon deposition, which will cause the vehicle to shake after starting adjustment. Generally, 90 # gasoline can be used when the engine compression ratio is lower than 7.5, 90 # gasoline or 93 # gasoline when the compression ratio is 7.5 ~ 8.0, 93 # gasoline or 95 # gasoline when the compression ratio is 8.0 ~ 10.0, and 97 # gasoline when the compression ratio is above 10.0.
Why can't Asian dragons sell Camry?
Asian dragons can't sell Camry for the following reasons:
Design:
Asia's leading China Net adopts a "vase-shaped" design, and the Lexus face has also enhanced a lot of luxury. The powerful fishbone three-eye headlight design makes its vision more firm and powerful, and the grandiose jaw also has high recognition and eye-catching rate. Camry is cooler. In addition, the front bumper design of different models is different, the professional version has more air inlets, and the shangfeng version of aerobics highlights the cool front face, making Camry more suitable for young people.
Interior design:
Kerry's streamlined and irregular interior is very attractive and layered. If it is black and red, the gas field of fitness is stronger. On the center console, Camry applied the design of leather product packaging and stitching decoration, and the luxury of the interior was greatly improved. The interior design of Asian Dragon lacks some flavor of fitness and sports, but the visual impact of the overall design is still very good. The interior with clear horizontal and vertical direction can give people a youthful, cutting-edge and heroic sense of trend, and that charm also solves the feeling of "greasy feeling". But for the top of the central control panel, there will be some reflection in the specific application, which is not enough.
Body specifications:
Asian dragon is half a level higher than Camry in precise positioning, and its market positioning is B-class car. Asian dragons need to be bigger than Camry in body size and track. The back seat space of Asian Dragon is nearly 4 fingers higher than that of Camry, and its indoor performance is very good.
