About autogas we know everything


In DUAL FUEL system, the engine is fed with LPG additionally to the regular feeding with diesel fuel.  The application of the DEGAmix system allows for a reduction of diesel fuel consumption between 20 and 30 percent, when the engine is simultaneously fed with much cheaper LPG.


The solution of ELPIGAZ company does not require interference with the engine fuel system both in mechanical part (high pressure) and in the ECU. The LPG is additionally dosed to the engine running on diesel fuel.A basic dose of diesel fuel is injected int the combustion chamber, while the additional gas portion is dosed to intake manifold. The ignition of additional gas dose initiates the ignition of the diesel fuel. The fuel dosage is adjusted by means of pressing on the acceleration pedal while the vehicle operates on diesel fuel.

DEGAmix system performs a self-adaptive dosage of gas into the engine.

 

DEGAmix system does not feed gas when idling, during braking with the engine, and on high revolutions.In case of failure of any DEGAmix elements, or after exceeding perimeter gas temperature in the exhaust manifold, the automatic cut off of gas feeding takes place.

Subsequently, the engine is powered by the diesel fuel only.The power of engine converted to DEGAmix increases about 10-15% simultaneously with the 20% increase of torque.  For most of the engines, increase of the torque is noticeable where it is needed most ie. in the low range. The vehicle clearly better accelerates and the engine is overall more flexible.

These figures definitely confirm drivers` opinions and observations gathered during test drives, and what is more tests made at a chassis dynamometer confirm this as well. Above diagram is an example of records made at homologated dyno, characteristics of the engine power and torque of a DAF XF 105.460 2006 truck with mileage of 520 000 km.

The engine of this vehicle powered only with diesel fuel reaches power of 431 HP (declared catalogue power of a new vehicle: 460 HP), and torque of ~2100 Nm. After turning on the DEGAmix system, the power of the engine  increases up to 491 HP (14% increase) and the torque up to ~2320 Nm (10,5% increase).  Moreover, the consumption of Diesel fuel notably decreases.
