Gas Injector Vercesi 5.0 Gray Cap

The injector with original code 166006623 and grey cap is a Vercesi component used in LPG and methane fuel systems with sequential gas-phase injection, employed on OEM or aftermarket systems. It falls into the category with an indicative flow rate suitable for (4-cylinder) engines up to 1.0 liters and power up to 44 kW.

The main specifications include:

• Equivalent codes: INJB051VRCN
• Connector: Packard type / 1st generation
• Number of injection holes: 12
• Mounting: on 4-injector rail
• Approvals: 10R-03 6710 (electromagnetic)
  67R-03 4893 (LPG)
  110R-00 4894 (METHANE)
• Compatibility: Landi Renzo Omegas, LSI and derivative systems

Functionality

The Vercesi grey-cap injector manages the precise dosing of gaseous fuel (LPG or methane) into the intake manifold, according to the injection timings calculated by the gas ECU. 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 every load phase.

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

Common faults and causes of failure

• Nozzle clogging: impurities or fuel residues cause reduced flow or irregular opening, leading to loss of power, irregular running or stalling.
• Electrical deterioration: faults in the solenoid or the AMP connector (broken wire, corrosion or internal short circuit) cause the injector to fail to activate.
• Mismatch between injectors: replacing a single injector without maintaining flow uniformity (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 different sizes (green, black, red cap) on non-corresponding engines can compromise correct dosing and cause malfunctions.

Conclusions

DIPA supplies the component new, ready for installation, with warranty and compatibility across all affected models. In the case of gas injectors, it is the exclusive distributor of Vercesi injectors (Iniettori gas gpl / metano - Vercesi Gas), the perfect solution for the performance, consumption and reliability needs of dual-fuel cars.
