SEQUENTIAL LPG KIT

Components of a Sequential LPG Conversion Kit:

1. LPG Tank (Cylinder or Toroidal)
   • Stores the LPG in liquid form.
   • Comes with multivalve for safety and functionality.
2. Multivalve
   • Mounted on the LPG tank.
   • Controls filling, supply, level indication, and safety cut-off.
3. LPG Reducer/Regulator (Vaporizer)
   • Converts liquid LPG into vapor.
   • Maintains constant pressure for the injectors.
   • Often heated by engine coolant to prevent freezing.
4. LPG Injectors
   • Inject vaporized LPG into the intake manifold.
   • Controlled electronically to match fuel injection timing.
5. Electronic Control Unit (ECU)
   • Manages the LPG injection timing and amount.
   • Interfaces with the original petrol ECU to mimic fuel behavior.
6. Changeover Switch (Fuel Selector Switch)
   • Allows the driver to switch between LPG and petrol modes.
   • Displays fuel levels and operating status.
7. LPG Filter
   • Filters out impurities before LPG reaches the injectors.
   • Can be in liquid or vapor phase depending on placement.
8. Fuel Lines (Copper or Flexible Hoses)
   • Transport LPG from the tank to the engine.
   • Must be pressure-resistant and compliant with safety regulations.
9. Coolant Hoses
   • Connect the engine cooling system to the vaporizer.
   • Required to prevent the vaporizer from freezing.
10. Wiring Harness
    • Connects all electronic components to the LPG ECU.
11. Pressure and Temperature Sensors
    • Monitor system performance and help the ECU adjust injection parameters.
12. LPG Level Sensor
    • Mounted on the multivalve or tank.
    • Indicates remaining LPG for the dashboard switch.

A sequential LPG (liquefied petroleum gas) conversion kit is an advanced system designed to convert a petrol engine to run on LPG, offering improved fuel efficiency and reduced emissions. Unlike traditional LPG systems, the sequential kit injects LPG into each cylinder in a precise, timed manner, mimicking the operation of a modern petrol fuel injection system. This results in smoother engine performance, better fuel economy, and more accurate control over fuel-air mixture. The kit typically includes components such as an ECU (Electronic Control Unit), injectors, a pressure regulator, and sensors, all working together to ensure optimal performance. Sequential LPG kits are particularly suited for modern vehicles with electronic fuel injection systems, providing a cleaner and more cost-effective alternative to petrol.
