Sequential Vapour Injection (SVI)


Port Adelaide Auto Repairs are qualified installers of Vapor injection LPG systems.

The difference between a standard LPG system and a SVI system is that the SVI injects the gas through a dedicated LPG injector closer to the inlet valves and has an ECU or computer that monitors the engine and controls each injector accordingly. This means the chances of a backfire are reduced to almost nil and the quantity of fuel injected is more accurately controlled and fuel economy is improved.

An LPG vapour injection system results to little or no loss of power in your vehicle, and there is a seamless transition from petrol to LPG and back again.

Port Adelaide Auto Repairs use a range of suppliers when fitting vapour injection systems and the type of vapour injection system selected for your car depends on several factors including: engine size, tuning features and physical size for compact application.
