DENSO injectors

​Reduced power and efficiency: A faulty injector may not deliver the right amount of fuel to the combustion chamber or do so in the wrong way, leading to incomplete combustion. The result is reduced engine power and poorer vehicle performance.

Increased fuel consumption: Improper fuel injection can cause the engine to run less efficiently, which usually leads to increased fuel consumption. The engine tries to compensate for the inefficient combustion by using more fuel to achieve the desired performance.

Irregular engine operation: Problems with the injector can cause irregular fuel delivery to the cylinders, manifesting as jerking, unstable idling or difficulty starting the engine.

Increased exhaust emissions: Incomplete fuel combustion due to faulty injection can result in increased emissions of harmful substances such as nitrogen oxides, unburned hydrocarbons and particulates. This not only harms the environment, but can also cause the vehicle to fail emissions tests.

Catalytic converter damage: Prolonged operation with faulty injection can lead to damage to the exhaust catalytic converter. Incomplete combustion can cause unburned fuel to enter the catalytic converter, where it is burned, generating excessive heat and potentially damaging the catalytic converter.

Potential engine damage: In extreme cases, malfunctioning injectors can lead to more serious engine damage, for example by igniting the fuel mixture at the wrong time, which can cause damage to pistons, valves or other key components.

If injector problems are suspected, it is recommended that diagnostics and repairs are carried out as soon as possible to avoid further potentially costly engine damage.
