ALEX IDEA – a system for modern direct injection engines


alex idea logo

ALEX IDEA is an innovative gas conversion kit for cars equipped with direct-injection petrol engines (i.e. TSI, FSI, TFSI, GDI, T-GDI, EcoBoost, SkyActiv, DISI, JTS, TBI, SIDI, DIG, DIG-T and TCE). It provides you with an above-average fuel economy. Thanks to specially control algorithms, it uses only 5-15% of petrol while competitive systems of this type require the injection of almost 20-30% of it.

Proven long-distance performance

ALEX IDEA kits have been subjected to long-distance tests on many vehicles. The testing has confirmed that all components work together optimally to ensure safe and economical driving. This gives us the certainty that our proprietary ALEX IDEA system is both efficient and reliable.

This is also confirmed by the data we collect from the workshops recommended by ALEX. A properly installed and equipped ALEX IDEA LPG system is practically completely failure-free. Drivers who already use the system pay attention to this – 99% of system users recommend them and would decide to buy them again. ALEX IDEA LPG installations are valued in particular for:

  • reliability and perfect compatibility of all components,
  • much higher driving comfort and smooth driving,
  • EU production,
  • 5-year warranty for ALEX IDEA controllers,
  • competitive prices for components and assembly.
The perfect configuration

The perfect configuration

ALEX IDEA systems are available in several versions and configurations. Its most important components include the ALEX IDEA controller, fuel pressure emulator, Barracuda or Super B injectors, SHARK or TURBOT reducers, Ultra360º filters, PTS-01 mapsensor, RGB switch, OCTOPUS multivalve, gas level sensor and electric wire harness.

Why is a small proportion of gasoline necessary?

In direct injection engines, petrol injectors are placed directly in the combustion chambers, and their tips are exposed to high temperature and the effects of combustion products. Therefore, the injectors need gasoline to clean them, and the flowing fuel to cool them. So the LPG system for direct injection engines should not permanently disable the gasoline injectors.

The amount of gasoline used for cleaning and cooling the injectors may vary, depending on the capabilities / algorithms of the gas controller and the requirements of a given car model. In the ALEX IDEA System, the proportion of gasoline most often is between 5% and 10%. In more complex power units it can be about 15%.

Many people who consider installing LPG in a car wonder how much gasoline consumption is while using the system. However, as can be seen in the above calculations, these are extremely small amounts. As a manufacturer of the ALEX autogas installations, we pay attention to the lowest possible consumption of gasoline, so as not to increase the operating costs of the installation for the user.

In cars with LPG installation, regardless of whether it is direct or sequential injection, gasoline remains the basic starting fuel. However, gasoline is only used when starting the engine and warming up the reducer – in the case of sequential systems and for cleaning injectors in LPG systems for direct injection.
