When the summer solstice arrives, what are the effects of high temperature weather on car engines? [ACRON Lecture Hall]

In the hot summer, the temperature during the day seems to be getting higher and higher day by day. Driving on the hot streets under the hot sun, the car also seems to feel the heat.

When the engine is working, due to the friction between the moving parts and the combustion of fuel, it will generate a lot of heat. Coupled with the greenhouse effect, most cities have high temperatures and long summers. The continuous high temperature weather affects the heat dissipation effect of the engine.

Harm of high temperature to engine

Power drop

After the engine temperature is too high, the intake air temperature will increase, which will cause the air density to decrease and the air-fuel ratio to be incorrect. At this time, it will cause the engine's power to decrease, and an incorrect air-fuel ratio will also cause a series of problems.

Increased fuel consumption

When the oil temperature is too high, some parts will be oxidized and decomposed, and the oil film will become thinner. During engine operation, it will follow the gap between the piston ring and the cylinder wall to the combustion chamber to participate in combustion and form carbon deposits, which will lead to increased fuel consumption.

Parts wear

Under normal circumstances, the engine oil temperature is 70-90 ℃; while driving at high temperatures, the oil temperature can reach about 120-130 ℃, the viscosity decreases, and the oil film's shear resistance decreases, resulting in accelerated wear of other engine parts, such as timing belt.

The timing belt plays a key role in the car. It is responsible for driving the crankshaft and camshaft of the engine to make them operate in a coordinated manner to achieve the correct combustion of fuel in the combustion chamber.

Since the timing belt is made of rubber, it is more afraid of high temperature, and it is prone to aging or even breaking over time. At the same time, any defects on the timing belt will lead to the early end of its service life, such as small cracks, imperfect synthetic materials, nicks/cuts, etc.

How to choose a high-quality timing belt?

The high-quality timing belt can ensure the normal operation of the car engine, enhance the performance of the car, and improve fuel efficiency. When choosing a timing belt, pay attention to its durability and compatibility.

Durability

It can be evaluated by examining the material and process of the timing belt. Characteristics such as high-strength materials, oil and heat resistance will enhance the durability of the timing belt.

Compatibility

It is necessary to choose the appropriate timing belt according to the brand and model of the car. In addition, when purchasing a timing belt, you should also pay attention to the after-sales service of the product, such as warranty policy, professional installation support, etc.
