There are two main reasons for the increase in oil. One is that gasoline enters the engine oil. Honda CRV? There have been similar incidents, and the oil will smell of gasoline. This is because too much gasoline in the engine combustion chamber adheres to the cylinder wall and enters the crankcase through the piston ring, resulting in an increase in engine oil.
The increase in oil may also be caused by water entering it. The source of water determines the treatment method, whether it is water vapor in humid air (natural cause) or coolant leakage or other reasons. If there is water in the engine oil, it will also cause emulsifying phenomenon of the engine oil. No matter what the reason, once there is moisture in the oil, it will affect the lubricating effect of the oil, so replacing the oil is a top priority. If the engine oil increases after normal use, natural causes can be basically ruled out, indicating that there is a problem. For example, Toyota North America oil valve incident, Toyota has recalled 44,000 Toyota hybrid and Lexus models in the United States. The reason for the recall is that the engine casting air hole may be heated, causing cracks, and then the coolant leaks into the engine, resulting in an increase in engine oil and emulsification of engine oil. It is estimated that the same is true for China. Now, I just hope that Toyota can live up to the support of China consumers for many years and handle this incident equally, instead of learning from the public to treat China consumers differently. If Toyota dares to be sorry to China consumers. I suggest that car owners can use legal weapons to safeguard their rights and interests. Class action lawsuit is a good way to deal with a big company like Toyota.
Let's talk about the dynamic torque control four-wheel drive system of Toyota Fangrong. The RAV4 with the model of 20 13 should be the first to introduce this system. But the new model is very different from the old one. Now RAV4 has added an all-terrain system to replace the front and rear axle torque distribution buttons that were manually switched. In addition, the torque distributed to the rear axle can be switched instantly between the two wheels. Because each rear wheel of the new RAV4 has an anti-skid device.
In addition, in order to save fuel consumption, the transmission shaft on the new Toyota RAV4 can be completely separated from the rear axle and does not rotate, while the old RAV4 can only be separated from the rear axle, but the transmission shaft will still rotate. In this way, the new RAV4 engine will not drive the additional transmission shaft to idle, which will lead to better fuel consumption and reduce the wear and tear of the four-wheel drive system. More importantly, the off-road ability is not discounted.
Finally, I want to give you some food. I didn't want to write so much. The new RAV4 looks hard-core, but its off-road ability is average. The following video explains the chassis material and structure of the new RAV4. The conclusion is that the chassis material is general, and the position of trailer hook or towing rope is not reserved. Once trapped, there is no way to rescue. If you are really not afraid of adding oil and emulsifying. If you must buy RAV4. We must do our best. Don't be too wild
