Why Spark LPG direct
Why Spark LPG direct
Spark LPG
The system brings several advantages
- SparkLPG liquid direct injection is a service friendly system.
- In addition, no changes are made to the engine’s cooling system so that the full power of the engine remains available.
- Direct injection using the environment friendly Autogas can also lead to a CO2 reduction of more than 10 %.
- For both new and existing vehicles compliance to the Euro emission standard remains so it is appropriate for OM installation.
- Direct injection makes it possible to exactly meter the amount of fuel to be injected. This ensures that the engine management system’s full capability can be utilized, and this ensures optimal fuel consumption and drivability.
Quality of operation allowed us to design system that is working oneengine for LPG as primary fuel and petrol as secondary reserve fuel. LPG direct is using specially designed turbine pump placed into tank. Design of the pump and multivalve is to be used on standard LPG tank.
