I asked, the water temperature inside the hood of the car is normal, and it smells a little mushy, w

There may be one of the following reasons.

The engine oil enters the combustion chamber to participate in the combustion, the piston ring and the cylinder liner are not completely run-in, and the oil enters through the gap; The piston ring is bonded in the groove, and the cone surface of the piston ring is reversed, losing the effect of oil scraping; The piston rings are worn excessively, and the oil runs into the combustion chamber through the opening gap; The oil pan oil level is too high; The valves and tubes are worn out, and the clearance is too large.

It can be solved by the following methods: the new car or overhauled locomotive must run in the engine according to the regulations, so that the parts can be meshed normally; Look at the assembly mark clearly and install the piston ring correctly; Replacement of qualified or oversized piston rings; Find out the reason for the increase in the oil pan oil level and release the excess oil from the oil pan; Reduction of oil in the filter pan; Replace the valve guide.

It is normal for a new car to have a burnt smell, and there are many oil circuits and plastic parts in the engine compartment of the front of the car, which will emit some burning odor when heated, and the burning smell will slowly fade as the car travels for more time.

In addition to this, brake pads.

Friction and clutch plate slippage will also produce a burnt smell when the handbrake.

When it is not completely put down, in the process of driving, the brake pads will be rubbed all the time, and it will produce a burnt smell; Gearbox.

Clutch slippage causes high temperatures, and it also produces a burnt smell, and when the clutch is not fully raised, the car is in a semi-clutch.

When the throttle is increased, the clutch plate will rub against the flywheel rapidly, resulting in a burnt smell, and if the slippage is severe, the taste may not disappear after more than ten days.

If the smell of burnt paste is particularly strong, it is necessary to pay attention to the inspection, which is likely to be caused by the aging of the electrical circuit or oil circuit in the engine compartment. The aging of the oil circuit in the engine compartment can easily cause line failure, and in serious cases, it will even cause the phenomenon of spontaneous combustion of the car.

It could be the smell of piston carbon.

The explanation is that the car has been driving for too long and needs to rest, and the engine is turning too fast and the water tank is a little burned. It's a minor issue, just stop and take a break.

The water temperature has nothing to do with the mushy taste, it may be a problem in other places, it is recommended to find a professional to see.

There must be a reason for smelling the burnt smell of the car. This kind of thing can be big or small. As for the reason, it's hard to say.

There are at least thousands of parts in a car, rubber, plastic, and metal, and each part has a different smell. Normally, most of the parts have a small smell under normal operation, but if there is abnormal wear or consumption, it will emit some pungent smell.

First, there is a smell of plastic in the cab.

Cause: Overheating of the wire or short circuit of the electrical appliance.

If you smell the smell of plastic products, it is mostly caused by overheating of electrical wiring. The burning of wires is generally accompanied by local heating or local smoke, as long as it is carefully inspected, it should not be difficult to find the source of the accident and determine the fault location. If the power line is overheated, you must stop it immediately to find out the cause.

Although the smell of wire burning is not large, the danger is very high. If not found in time, it is easy to cause circuit damage, engine cylinder pulling, and even spontaneous combustion of the whole vehicle.

Second, there is a peculiar smell in the car when the air conditioner is turned on.

Cause: The air conditioner filter or air supply duct is not clean.

The air duct of the air conditioner, the trunk of the car, the floor mats and other parts are all important sources of pollution, so it is best to clean the car thoroughly immediately when you smell a peculiar smell.

Hello, first of all, check whether the rubber pipe products are burned. Also check for line issues!

The owner of the car drove the vehicle to travel, and after arriving at the destination, when he stopped to check the vehicle, he smelled a mushy smell, and after opening the hood, he found that it was emitted from here, so what is the reason for the mushy smell in the hood after parking?

1. There are a lot of plastic parts inside the engine of the vehicle, and the plastic parts will emit a mushy smell after being heated, especially for new cars, the owner does not need to be too nervous, as long as he pays attention to controlling the temperature of the engine and the water tank.

2. It may be that the clutch of the gearbox is slipping, and the owner will also smell the mush, and the owner needs to go to the 4S shop in time to check and repair the gearbox of the vehicle.

3. It may be that the oil circuit or circuit in the engine compartment is aging, and the vehicle should be checked by the 4S shop, and if there is a problem, it needs to be replaced in time to avoid serious consequences, because the reason for the spontaneous combustion of many vehicles is the aging of the oil circuit of the car.

If the owner finds that the vehicle smells mushy, he needs to drive the vehicle to a 4S shop or auto repair department as soon as possible, and then drive on the road after repair.

The reasons for the combustion of the engine compartment are as follows:

Gasoline burns inadequate:

Starting the car in winter, the low temperature increases the difficulty of gasoline atomization and affects combustion. Some of the unburned gasoline molecules are discharged through the exhaust pipe and enter the car through the outer circulation.

Brake pad friction:

When the handbrake is not fully put down, it will always rub the brake pads when it is opened, which will produce a smell of burnt metal. Or some of the metal particles of the brake pads are larger, and these metal particles will briefly appear to burn the key after wear.

Clutch disc failure:

The clutch plates of the gearbox slip, creating high temperatures that produce a burnt taste. When you step on the accelerator uphill, the clutch does not lift, resulting in a slow tassel of the semi-mold. When you press the accelerator, the clutch plates and the flywheel rub against each other quickly, creating a burnt smell.

If you press the throttle for a long time, the clutch plates can easily burn out.
