Quick Answer
A single-point CNG/LPG system supplies gas through one central delivery point, while a sequential system uses an ECU and injector rail to manage gas delivery for individual engine cylinders. The suitable system depends on the original engine configuration, vehicle application and conversion-project requirements.
What Is a Single-Point CNG/LPG System?
A single-point conversion system supplies gas through a central mixing or delivery arrangement before it enters the engine intake system. This system type is commonly discussed for vehicle applications with simpler fuel-system configurations.
Before selecting a single-point system, confirm the vehicle engine type, existing fuel-system arrangement, required gas fuel and available installation space.
What Is a Sequential CNG/LPG System?
A sequential conversion system uses an electronic control unit and injector rail to manage gas delivery for individual cylinders. The system is discussed for vehicle applications that require electronic coordination between the original petrol system and the gas conversion system.
Sequential-system selection should consider the cylinder quantity, petrol injection type, ECU configuration, electrical connection requirements and compatible gas components.
What Information Is Needed Before Choosing?
Vehicle make, model, model year and engine displacement
Number of engine cylinders
Original petrol fuel-injection configuration
Required fuel: CNG or LPG
Passenger car, taxi, fleet, light truck or motorcycle application
