Vercesi Injector 5.0 Black 2 Generation

The injector with original code 77366187 and black cap is a Vercesi component used in LPG and methane fuel systems with sequential gas-phase injection, employed on both OEM and aftermarket installations. It falls into the flow-rate 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: INJB010VRCN

• Connector: Fiat type / 2nd 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 systems, LSI and derivatives

Functionality

The Vercesi black-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 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 condition.

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: faults in the solenoid or the AMP connector (broken wire, oxidation or internal short circuit) cause failure to activate the injector.
• Mismatch between injectors: replacing a single 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 cap, black, red) on non-matching engines can compromise correct metering and cause malfunctions.

Conclusions

DIPA supplies the component in new condition, 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 (LPG / methane gas injectors - Vercesi Gas), the perfect answer to the performance, consumption and reliability needs of dual-fuel cars.
