Common automobile faults and ways to cope with

When the car turns, the steering wheel obviously turns a big turn but turns into a small turn, the steering wheel obviously turns a small turn but turns into a big turn!

Reason analysis: the two phenomena occurring when steering the former is called understeer, the latter is called oversteer, indicating that the steering system problems. Drivers in the car steering side of the car around the side of the acceleration of the feeling is: with the understeer performance of the car will be traveling to the outside side, with the oversteer performance of the car will be traveling to the inside. When the radius of travel becomes large, it is called understeer. When the radius of travel becomes small, it is called oversteer. There is another type of steering phenomenon that starts out as understeer and then becomes oversteer midway through, turning sharply to the inside. This is the most dangerous reverse steering phenomenon and is prone to accidents. This situation only occurs in individual rear-engine vehicles.

Fault Determination: True Fault

The engine is difficult to start cold, the engine vibrates after starting, and then tends to stabilize, the engine begins to shake at low speeds, and improves at high speeds.

Cause analysis: may be a spark plug failure or ignition moment too early. If it is not a spark plug failure, you can judge the ignition moment is too early. If the ignition moment is too early, in the electric spark flash over the moment, the piston from the upper stop is far away from the cylinder mixture of pressure and temperature are not high, resulting in the formation of a slow flame, and the flame is formed after the propagation of the speed is also low, in the process, the combustion chamber away from the spark plug far from a part of the mixture can not wait for the spark plug to come from the pilot flame, due to the temperature of the mixture has been burned radiant and expansion and automatic combustion, resulting in Deflagration, deflagration caused by the engine in the low-speed jitter serious. When the above faults occur, should be timely to the repair shop for repair.

Failure to determine: the real fault

Vehicle rear door can not be opened from the inside

Reason analysis: the current car is generally installed in the vehicle's back door with a child lock, to prevent children riding in the back seat out of misuse of the car door open, a security accident. Many people in the cleaning of the vehicle due to inattention, move the handle of the child lock, ride in the back seat occupants from the inside to open the door. This is not a malfunction, just open the door from the outside of the vehicle and then move the child lock handle to the open position.

Fault Determination: False Malfunction

Small airflow from air conditioning vents

Cause analysis: The air volume of the air vents inside the vehicle will gradually become smaller with the use of the vehicle at the same fan speed, and the cooling effect is also weakened. Generally this is because a lot of new cars are installed air conditioning filter, the purpose of the installation is to keep the vehicle interior to get clean air, which also makes the air conditioning evaporator to keep clean, to get the best cooling effect. After a period of time, the filter can become covered with dirt resulting in less breathability and consequently less airflow from the vents. Therefore, just replace the filter with a new one and the problem will be solved.

Fault Determination: Maintenance Failure

When refueling, the engine speed rises but the vehicle speed cannot be increased.

Cause Analysis: Vehicle driving if you find the vehicle acceleration, especially rapid acceleration when the vehicle can not be increased with the engine speed and speed, for the manual transmission, generally due to clutch plate damage. Automatic transmission vehicles is generally due to the transmission friction plate damage caused. At this point, you can no longer accelerate to avoid greater economic losses. Should seek assistance or slowly drive the vehicle to the workshop for repair.

Failure to determine: the real fault

Driving in the engine has a deflagration sound, especially when accelerating obviously

Reason analysis: deflagration sound similar to the valve stem sound that is “click” sound. As most of the new engine using hydraulic tappet, will not occur the valve stem clearance is too large sound, the actual is a kind of deflagration sound. This sound is mostly due to the use of low-grade fuel. To troubleshoot this, a more compliant high grade fuel is required. This kind of noise is most obvious in the Cherokee. If you can not buy a fuel that meets the requirements of the moment, then the appropriate adjustments in the ignition accordingly.
