Gas Injector Vercesi 5.0 Purple Cap

The injector with original code 237129000 and purple cap is a Vercesi component used in LPG and methane fuel systems with sequential phase gas injection, employed on original or aftermarket systems. It falls into the category with indicative flow suitable for engines (4 cylinders) over 2.0 liters and powers over 110 kW.

Main specifications include:

• Equivalent codes: INJB056VRCN
• Connector: Packard/1st generation type
• 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 purple cap injector manages the precise metering of gaseous fuel (LPG or methane) to 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 phase.

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 power loss, 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.
• Mismatched 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: fitting injectors of a different size (green cap, black, red) on non-corresponding engines can compromise correct metering and generate malfunctions.

Conclusions

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