DLM stands for ‘Direct LiquiMax’. This system is based on injecting LPG in liquid form into the engine using direct injection (DI) technology. Next to the VSI-DI system, the DLM system is another system developed for cars with a direct injection fuel system.
The Prins Direct LiquiMax system consists of high-quality components that are mounted in parallel to the standard fuel system. The DLM system uses some of the mechanical components and the electronics that are already fitted to the vehicle. This ensures optimal integration.
- High-quality components
- For cars with a direct injection (DI) engine
- For mono-fuel and bi-fuel applications
- Extremely low petrol consumption
- Significantly reduced emissions
- Award-winning design
No noticeable difference compared to running your vehicle on petrol!
Is there a DLM system for your car?
The number of LPG conversions for cars with a direct injection fuel system is growing rapidly. Thanks to our extensive range of products, we are a pioneer in the market. Experience taught us which system works best for a particular engine.
We can convert all cars with an MPI (multipoint injection) engine to LPG with our VSI-2.0 LPG-system!
The following are the main components that are added to your car when a DLM-LPG conversion is installed.
The components that make up our DLM system are shown below. The main components meet the same standards as OEM-parts, and have been specifically developed for LPG systems. They satisfy the most demanding regulations and certification standards.

1. LPG-tank
2. ECU (Electronic Control Unit)
3. Switch
4. Fuel management unit (FMU)
5. High pressure pump (brandstofpomp)
6. Boostpump
