Four-Cylinder LPG Configuration and Private-Label Options
This LPG sequential injection kit is offered for compatible four-cylinder PFI/MPI gasoline engines. The core configuration lists a gas ECU, four-channel injector rail, LPG reducer, wiring harness and MAP sensor.
OEM and ODM requests are reviewed against the selected hardware and project requirements. Specify the engine application, component list, branding and documentation needs before requesting samples or a production quotation.

Which Components Need to Be Matched?
The ECU, injectors and reducer must form a compatible configuration. Confirm model numbers and operating requirements rather than selecting components only by cylinder count.
Gas ECU: Match engine signals, injector channels, sensor types, firmware and calibration software.
Injector rail: Match electrical drive requirements, gas flow, nozzle configuration and operating pressure.
LPG reducer: Confirm inlet fuel phase, delivery capacity, outlet behavior and any heat-supply requirements.
Wiring harness: Verify connector assignments, power supply, grounding and vehicle connections.
MAP sensor: Confirm the supported pressure range, signal characteristics and installation arrangement.
The storage and installation equipment must be specified separately on the quotation. Confirm whether the LPG tank, multivalve, filling connection, shutoff devices, mounting hardware and communication cable are included. See our conversion kit component guide for related information.
OEM and ODM Project Scope
Brand customization and technical development require different project definitions. Provide a separate specification for each requested change so sample acceptance and production requirements can be agreed.
Logo and labels: Supply artwork, marking locations and required product identification.
Packaging: Specify neutral or branded boxes, packing quantities and label information.
Harness requests: Provide pin assignments, connector references, lengths and routing requirements.
Calibration requests: Identify the engine, hardware configuration, software version and validation targets.
Hardware changes: Submit drawings and required electrical, mechanical and environmental specifications.
Project documentation: Identify destination-market approval and traceability requirements.
Firmware changes, branded diagnostic software and emissions-related development require separate review. Availability depends on the controller platform, development scope and agreed validation work.
Factory and Processing Images
Engine Selection and Calibration
Engine code, injection type and fuel demand determine suitability. Provide displacement, power, aspiration type and the intended operating conditions. Displacement alone does not establish compatibility with a naturally aspirated or turbocharged engine.
Direct-injection engines require a separately supported system. This PFI/MPI application does not establish GDI compatibility. Review our direct-injection conversion guide when identifying the engine type.
OBD functions depend on the selected ECU and software. If required, request the supported vehicle protocols and documented functions. Confirm calibration requirements using the injector rail and ECU calibration guide and the supplied controller instructions.
Frequently Asked Questions
Does a one-kit sample order include all customization services?
Sample quantity and customization scope must be agreed separately. Confirm artwork, tooling, development work, charges and acceptance criteria before ordering.
Can this kit fit any four-cylinder gasoline engine?
Compatibility requires a specific engine and component review. Confirm the engine code, injection type, signals, fuel demand and installation space. Four cylinders alone do not establish suitability.
Will the conversion deliver a fixed fuel-cost saving?
Operating-cost savings depend on local prices and measured consumption. Compare cost per distance using LPG use, retained gasoline use, maintenance and conversion cost.
Will LPG operation preserve the original engine power?
Performance must be verified on the installed vehicle. Engine condition, component sizing, fuel properties and calibration affect the result. No fixed power-difference percentage is specified here.
What maintenance interval should be followed?
Use the schedule for the supplied components and operating conditions. Follow filter replacement requirements and inspect gas lines, connections, wiring and any coolant circuit according to the system instructions.
What warranty is provided?
The stated warranty period is 24 months. Confirm coverage, exclusions, claim procedure and any project-specific terms in the quotation.
Documentation and Installation
Technical and approval records should identify the selected component models. Request datasheets, wiring diagrams, installation instructions and the applicable inspection or approval documents required for the project.
Installation and commissioning require qualified personnel. Verify mounting, routing, electrical connections and gas fittings, then complete the specified functional checks, leak tests and calibration.
