What is the lack of power of EFI diesel hot car?

One is incomplete combustion, and the other is insufficient air intake. Almost all vehicles with this kind of fault have passed the nozzle test process and are checked as normal. In fact, the working efficiency of fuel injectors is directly related to the power and economy of vehicles. Poor atomization or excessive fuel injection will directly lead to insufficient combustion, black smoke or cylinder loss of the engine. Only by completely replacing the fuel injector can we completely rule out whether it is a fuel injector fault. Only partially replacing the injector can not determine which cylinder injector is not working properly. Once the partial replacement effect is not obvious, the injector fault will be eliminated artificially, which will lead to the fault lasting and more hidden. Although the maintenance cost of replacing all injectors is high, it is far more profound than tossing and turning.
