Vercesi Injector 5.0 Black I Generation

The injector with original code JNV906031A and black cap is a Vercesi component used in LPG and methane sequential gas-phase injection fuel systems, employed on OEM 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 power outputs from 75 to 110 kW.

The main specifications include:

• Equivalent codes: INJB002VRCN
• 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 (CNG)
• Compatibility: Landi Renzo Omegas, LSI systems and derivatives

Functionality

The Vercesi injector with black cap controls the precise metering of gaseous fuel (LPG or methane) into the intake manifold, according to the injection timings calculated by the gas control unit. The control system is electromagnetic, with 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 phases.

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

Common faults and causes of failure

• Clogging of the injection 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, corrosion or internal short circuit) cause the injector not to activate.
• Injector mismatch: replacing a single injector without maintaining uniform flow rates (all blue cap, same code or all new) can create imbalances in injection timing, resulting in phasing issues and ECU errors.
• Calibration or compatibility error: fitting injectors of different sizes (green, black, red cap) on non-matching engines can compromise proper metering and cause malfunctions.

Conclusions

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