Injector Vercesi 5.0 Blue 2 Generation

The injector with original code 77366838 and blue cap is a Vercesi component used in LPG and methane fuel systems with sequential gas-phase injection, employed on original or aftermarket installations. It falls into the category with an indicative flow rate suitable for (4-cylinder) engines from 1.6 to 2.0 liters and powers from 75 to 110 kW.

Main specifications include:

• Equivalent codes: INJB055VRCN
• Connector: Fiat type / 2nd generation
• Number of injection holes: 12
• Mounting: on a 4-injector rail
• Approvals: 10R-03 6710 (electromagnetic)
  67R-03 4893 (LPG)
  110R-00 4894 (METHANE)
• Compatibility: Landi Renzo Omegas, LSI and derivatives

Functionality

The Vercesi blue-cap injector controls the precise metering of gaseous fuel (LPG or methane) into the intake manifold according to the injection timing calculated by the gas ECU. The control system is electromagnetic, with the opening and closing of the internal valve operated by a solenoid.

The flow rate allows use on a wide range of 4-cylinder engines, ensuring the correct stoichiometric ratio during every load phase.

DIPA recommends always verifying compatibility based on the characteristics of the original equipment injector.

Vehicle applications

Common faults and causes of failure

• Orifice clogging: impurities or fuel residues cause reduced flow or irregular opening, leading to power loss, rough running or stalling.
• Electrical deterioration: solenoid or AMP connector failures (broken wire, oxidation or internal short circuit) cause the injector not to activate.
• Injector mismatch: replacing only one injector without maintaining uniform flow (all blue cap, same code or all new) can create imbalances in injection timing, causing phase shifts and ECU errors.
• Calibration or compatibility error: installing injectors of a different size (green, black, red cap) on non-matching engines can compromise correct metering and cause malfunctions.

Conclusions

DIPA supplies the component new, ready for installation, with warranty and compatibility for all affected models.
