How much impact does the engine of a vehicle have on the second hand car transaction?

There is no clear definition of how much the depreciation of the car with the engine is replaced, and the main thing is to judge the impact of the replacement engine on the performance and the reasons for the replacement of the engine.

If the replacement is caused by water or traffic accidents, then the car will depreciate more, and if it is just an ordinary replacement engine that has no impact on the car and there is no error in the installation, the depreciation will not be much. In addition to the engine, the car is like a gearbox.

Transaxle, steering and braking systems.

It's all the same.

The replacement of the engine is a relatively large maintenance, which needs to be repaired professionally in the 4S shop, and the maintenance quality can be guaranteed with the support of the manufacturer, which will not cause great deterioration to the car.

The advantage of changing the engine assembly is undoubtedly to bring more excellent power performance, and you can also make some subtle program adjustments according to your own preferences, so as to improve the driving atmosphere of the whole vehicle. But there are two sides to everything, and the same is true for changing the engine assembly, you must know that the engine is a very complex instrument, and there must be no mistakes in the installation and matching, otherwise there will definitely be certain safety hazards.

It even causes "secondary damage" to the whole vehicle, and the slightest carelessness is the death of the car.

In general, it is recommended that you do not modify the engine assembly, as the so-called "thousands of roads, safety first", driving safety must be our first consideration. But if we are really very obsessed with modifying the engine assembly, we must go to some large-scale modification shops to replace it, after all, the masters there have a certain amount of modification experience, unlike other small shops, which are often just "half a bucket of water".

Hello. Itself, if the engine is replaced, it has little impact on the second-hand car of the car, but it mainly depends on what situation causes the damage to the engine, if it is caused by a serious accident, then it is possible, Ge, it will decline slightly, if it is because of the engine itself, there are some problems, directly replace the engine, this is not affected or anything, hope.

The engine replacement has a very large impact on the second-hand car transaction, which means that your car has been similar to the kind that has had a serious accident, and then the second-hand car transaction, that ** will definitely be much lower than the previous one.

Of course, you can, but you have to be mentally prepared, the second-hand engine is definitely not as good as the original.

Many people think that just like the cylinders of the V-shaped engine are arranged in a V-shape, the cylinder arrangement of the W-type engine must also be in a W-shape, but in fact, it is only an approximate W-shaped arrangement, strictly speaking, it should also belong to the V-shaped engine, at least a variant of the V-shaped engine.

The W-engine, the W-engine is the German Volkswagen.

Proprietary engine technology. The cylinders on each side of the V-shaped engine are staggered at a small angle to form a W-shaped engine. In other words, the cylinder arrangement of the unchanged W-shaped engine is composed of two small V-shapes to form a large V-shape, and the two groups of V-shaped engines share a crankshaft.

Strictly speaking, the W-type engine should also be a variant of the V-type engine.

Compared to the V-engine, the W type can make the engine shorter, and the crankshaft can also be shorter, which saves the space occupied by the engine, and at the same time it can be lighter, but it is wider and the engine compartment is fuller.

Of course, the repaired engine can be bought, this depends on how much damage you have, generally speaking, if the engine has been overhauled, it is best not to buy.
