Injector Vercesi 5.0 Blue 1 Generation

The injector with original code 237128000 and blue cap is a Vercesi component used in LPG and methane gas-phase sequential injection fuel systems, employed on OEM or aftermarket installations. It falls into the flow category suitable for (4-cylinder) engines from 1.6 to 2.0 liters and power outputs from 75 to 110 kW.

The main specifications include:

• Equivalent codes: INJB008VRCN

• Connector: Packard / 1st generation type
• 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 systems and derivatives

Functionality

The Vercesi blue-cap injector manages 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 controlled by a solenoid.

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

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

Common faults and causes of failure

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

Conclusions

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