All about Dual Fuel Systems

Why Hi-TEC Dual Duel Systems for your diesel engine?

• Available with LPG/CNG/LNG
• For all types of vehicles with a diesel engine, the newest (Euro 6), as well as the less advanced, which do not have advanced engine control systems.
• Built-in fuel consumption monitoring for Diesel and Gas.
• An alternative for investing in expensive vehicles powered by natural gas only (NGV)
• First dual fuel system with automatic calibration and correction of gas injection
• Full synchronization of gas injection frequency with engine speed and the number of cylinders, which ensures a uniform supply to all cylinders, better engine smoothness and increase in the efficiency of gas as additional fuel.

• Monitoring of key vehicle performance parameters and recording them in internal memory
• Gas injectors monitoring sensor protecting engine from uncontrolled gas injection
• Diesel and gas level and consumption monitoring
• Recording of route and distance based on information from built-in GPS module
• Ability to connect up to 2 fuel probes directly to the system controller for monitoring fuel level in Diesel tanks
• Temperature monitoring for the engine, gas reducer and exhaust gas

In its internal memory the system controller records data needed to prove the effects of its performance. At an moment in time the data is available for download to your computer hard drive for fuel consumption or route analysis, error diagnosing, etc.

For example: Diesel consumption data is retrieved directly from the vehicle’s CAN. Gas consumption is calculated based on gas injectors working parameters. Fuel consumption summary in a given period allows you to verify consumption calculated from refueling.

Route and distance travelled is recorded from the built-in GPS module, which makes the system independent from the on-board computer and gauges, and shows the actual mileage.

There are two main types of air pollution in cities, which contribute to the creation of harmful smog.

• Solid particles are one of them, and they are emitted in a substantial amount by diesel engines.
• Photochemical

• The main source of smog in summer is emission from vehicle exhaust
• This process cannot be reversed, but it can be fixed by making diesel engines more environmentally friendly.
• Dual fuel system reduces harmful substances.
• The reduction has been confirmed by tests made by Polish Motor Transport Institute and Poznań University of Technology

The purpose of this work was conducting tests of exhaust fumes emissions (CO, NOx, THC, PM, PN) from exhaust system, maximum net horse power on wheels and verification of correct functionality of the OBD system in vehicles PEUGEOT 508 GT and PEUGEOT BOXER 3.0 HDI equipped in self-ignition engines supplied with diesel (mono fuel) or mixture of diesel and liquid gas propane-butane (dual fuel).

Vehicles presented for test were equipped with installation Solaris Diesel adapting them to be supplied with mixture of diesel fuel and liquid gas propane-butane, which was manufactured by company PHU Car-Gaz.

The chart shows the emission results obtained on the Peugeot Boxer 3.0 HDI. The results obtained during the city cycle and the highway cycle while the dual fuel system was on are compared with the results obtained under the same conditions while the vehicle drove only on diesel fuel [diesel = 100].

Measurement of emissions of exhaust fumes from the exhaust system [mg/km |#/cm3] followed by test type I Regulation 86.06 EKG ONZ, amended series 06 with diesel supply.

The chart shows the emission results obtained on the Peugot Boxer 3.0 HDI and Peugeot 508 GT. The reduction of emissions is directly proportional to the engine size and to the quantity of fuel consumed by the engine. The larger the engine displacement the higher percentage in emissions reduction is achieved. Engines that comply to the strict Euro 5 and Euro 6 norms, can also benefit from the diesel dual fuel technology and lower their emissions even more.

CO2 emission research has been done at the road stretch, with total length of 56 km. The object of the research was a tractor-trailer Scania R450 Euro 6. The vehicle has advanced exhuast gases purification system, which includes EGR, DOC, DPF, 2 SCRs and 2 ASCs.

The object of the research was a tractor-trailer Scania R450 Euro 6 equipped with dual fuel system Solaris Diesel.

For the measurment of the fuel consumption and CO2 emissions was used mobile instrument. The instrument had GPS and enabled communication with vehicle diagnostic system.

The chart shows the results of the CO2 emission test on Scania R450 Euro 6 with applied dual fuel system and only on diesel The reduction of CO2 emission is 4,59%.

One adult African elephant, this is the weight of the CO2 emission during 1 year that could be reduced with dual fuel system * Despite the harsh emission standards for buses with EURO 5 emission standard, our system allows for the 5,6% reduction of CO2 emissions. Reduction in case of vehicles with emission standards EURO 1 to 4 is more evident.

*Assumptions: Bus; consumption 50l diesel; dual fuel mixture 36,5l diesel + 17,6l LPG; 100.000 km per year; weight of 1 elephant 7.500 kg; emission standard EURO 5
