What is the meaning of VVT, DVVT, CVVT, etc. on the car engine?

What are the reasons why radiator fans often fail? Today we will answer them for you.

The difference lies in their working principles.

In the era of electric vehicles, do we really not need engines?The answer is no. In 2023, 13.03 million new energy vehicles were sold worldwide, of which 3.91 million were PHEVs and REEVs with internal combustion engines, and 9.12 million were pure electric vehicles.

The difference between the high-power EA888 Gen3 and the low-power EA888 Gen3B (three and a half generations) engines is actually very large. Due to the use of completely different combustion systems and performance targets, there are many differences in hardware.

Volkswagen/Audi EA888 second generation oil-gas separator (waste valve)The original car is divided into two versions of high and low powerWhen replacing, just match the original car number!

The camshaft is inspected from three aspects: inspection and adjustment of axial clearance, inspection and repair of camshaft bending deformation, and inspection and repair of other cam wear. The third aspect is divided into inspection and repair of camshaft journals and bearings.

The engine water pump is an important component in the engine cooling system. In the engine cylinder, there are multiple water channels for coolant circulation, which are connected to the radiator (commonly known as the water tank) placed at the front of the car through water pipes to form a large water circulation system.

With the rapid development of new energy vehicles, internal combustion engines are getting closer to being eliminated. Hybrid vehicles and electric vehicles have more advantages in reducing emissions and lowering operating costs. In addition to pure electric vehicles, engines still play an important role in plug-in hybrid and extended-range vehicles.

During the installation of the EA888 timing side cover, there will be oil leakage. We all need to pay attention to those aspects. Next, let's take a look.

In the last issue, we mentioned four reasons why the water pump leaks：Leakage caused by sealing gasket；Leakage caused by oil/butter applied to the gasket；Failure to use regular antifreeze leads to leakage；Leakage caused by failure to replace accessories synchronously.Today we introduce other factors

What does the crankshaft of an engine do? How does it relate to the engine work order?

When installing the water pump of EA211 or EA888 models, it is forbidden to use sealant because the water pump is already equipped with a sealing ring when it leaves the factory.

According to multiple media reports, due to software issues, Germany's Volkswagen Group has once again postponed the launch of several electric vehicles, including the ID.4 replacement model and Porsche's new electric SUV.

Diesel engines have many advantages, such as higher compression ratio, stronger anti-knock performance, more complete combustion, thus improving fuel economy; no need for ignition system structure is simpler, engine stability is better, maintenance cost is lower; low torque output is very strong, and it can also be widely used in heavy trucks and ships.

With the change in car consumption habits, automatic transmission cars are becoming more and more the first choice for car purchases. So what gears do the letters on automatic transmission cars represent?

Nissan's latest generation HR16 engine uses advanced sound insulation technology, which reduces noise transmission and resonance to a minimum by accurately calculating and optimizing the internal structure of the engine.

Why are most Japanese cars with automatic transmissions CVT gearboxes?There are many reasons. CVT transmission has many advantages in fuel saving, emission, power and cost.
