Blocking of diesel injector is one of the most common faults of car engines. It can directly affect combustion efficiency and vehicle performance.

Common reasons for blocking of diesel injector:

Poor fuel quality: Fuel containing impurities or moisture may experience carbon deposits, which can block the nozzle at high temperatures.

Carbon deposition: After long-term use, dust or sediments in the diesel injector can affect the fuel injection effect.

Long-term short-distance driving at low speeds: Low engine temperature leads to insufficient fuel combustion and carbon accumulation.

Bad maintenance habits: These habits include irregular cleaning and using low-quality fuel.

Symptoms of blocked diesel injector:

Instability in idle status: The engine shakes or becomes unstable in idle status.

Weak acceleration: The accelerator responds to control slowly, and feels jerky.

Higher fuel consumption: Fuel efficiency becomes lower, and fuel consumption increases.

Difficult cold start: The first ignition fails, and multiple attempts are required.

Abnormal exhaust: The exhaust pipe emits black smoke and generates a pungent smell of fuel.

Fault light on: The ECU detects abnormal air-fuel ratio (common fault codes: P0171 too lean mixture/P0300 random misfire).

Advantages of vika diesel injector:

The cleanliness of the components of vika diesel injector can reach Grade AA.

Ultra precision machining leads to better atomization effect.

The gasket parallelism is 1u, and the grading accuracy is 0.002 mm, both better than those of aftermarket products.

The return fuel volume of vika diesel injector is 30% smaller than original products, leading to higher engine efficiency.
