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.
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 lies in their working principles.
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.
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.
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.
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
Diesel engine gasket ablation (commonly known as cylinder gasket ablation) is a relatively common problem. Due to the different locations of gasket ablation, its manifestations are also different.
There are many common reasons for failure. The first reason is that the electronic fan does not rotate or the speed is abnormal.
What are the reasons why radiator fans often fail? Today we will answer them for you.
