…Tomorrow’s Technology, Today

The dg System
The dg system is a new generation lpg injection technology that accurately delivers lpg as a liquid into large diesel engines. The dieselgas technology reduces greenhouse gas emissions and cuts operating costs, whilst maintaining driving performance.

lpg has been used for more than 40 years in light vehicle spark ignition engines in vapour form. The difficulty has always been to get enough lpg into a large engine.

The dg system solves this by injecting cold liquid lpg fuel (at -37?c) into the cylinders on a sequential basis, utilising its world-patented conjector (left). Liquid injection ensures accurate delivery of the required fuel quantities and the vapourisation of the fuel assists inter-cooling to improve the engine’s efficiency. The dieselgas ecu ensures this delivery is accurately timed to coordinate with the intake of air and diesel.

dieselgas’ ecu has been fully mapped to optimise the required amount of lpg and diesel for every engine speed and load combination whilst performing within the parameters of the OEM’s power curve specifications. Under typical freight tasks, the fuel mix will contain at least 60% lpg, which, given lpg’s significantly lower price profile and improved emissions characteristics, delivers the cost and emissions savings. The vehicle’s original diesel tank will be replaced by a bespoke diesel and lpg tankage solution. The vehicle can still be operated on 100% diesel at any time.

dieselgas’ system is non-invasive to the vehicle or OEM ecu.

System availability
The dg system is available for installation in the UK, initially on the DAF430 (Euro III) with other Euro IV models soon to be released. No modifications are made to the engine or chassis that would interfere with the integrity of the original OEM design.
