The next generation of diesel gas injection has arrived. Utilising the latest sequential vapour injection technology, DieselGas Sequent II delivers even more power with greater fuel savings than ever before. The high pressure vapour injection system used in the DieselGas Sequent II system provides constant split-second adjustments to meet all operating conditions. The system is self adjusting, so it can adapt to your driving style, automatically moving from economy to power delivery as driving conditions demand. Calculations are carried out at a rate of ten per second – the injector then responds in time for the next revolution of the crankshaft! This is now the bench mark for diesel gas injection systems
Three methods of Diesel Gas Fuel Control
Fixed hard settings and jetting - unable to react and respond to RPM, load and boost changes
Ventury and stepper motor - 10-18 second reaction time. A terrible amount of damage can be done in this time.
Direct injection - 1/10 of a second reaction time.
The direct diesel gas injection systems we use are supplied by Gas Tek Global as seen on New Inventors on ABC. Gas Tek Global is the industry leader in the development of diesel LPG injection systems and diesel gas conversions. Since the release of the first systems in 2006, their in-house R&D team has kept them years ahead of any other diesel gas injection system on the market. As a result they outperform all of their competitors easily in every field including power, fuel savings, emissions and safety features.

DieselGas Sequent II allows LPG to be used at idle, substituting a percentage of diesel required for idle. Over extended idle periods, such as in traffic, this substitution adds up to a significant reduction in diesel consumption. This reduction is on top of the usual economy benefits of DieselGas.
Injecting gas from idle improves power delivery right off the mark. There is no delay of waiting for revs or turbo boost pressure to build up – gas flow is ramped up instantly as you take off compared to the diesel only fuel system. Typically a 20-25% power gain is achieved with up to a 30% increase not uncommon with the Sequent II System.
The absolute accuracy of the DieselGas Sequent II guarantees LPG is only used when it is needed. Gas flow is shut off instantly and completely for gear changes, under brakes and when coasting downhill. With this level of control, LPG consumption is reduced by around 20% and in some cases more.
Automatic Self Adjusting
DieselGas II adjusts itself as you drive! It constantly adapts to your driving style. The system constantly adjusts to deliver performance or economy as the conditions require. This means that your DieselGas system is tuned with 100% accuracy to deliver the best possible results.
Injection Accuracy and Control
The DieselGas Sequent II processor reads all sensors continuously and constantly adjusts air flow. The injector responds in time for the next revolution of the crankshaft. The level of accuracy ensures that only the correct amount of LPG is injected at precisely the right time. This level of accuracy and control allows the engine to operate at maximum efficiency under all driving conditions.
Engine Protection
DieselGas Sequent II also offers surpassed engine protection – it constantly monitors engine coolant temperature and exhaust gas temperatures. In the event of engine overheat, regardless of the cause, the system will either reduce or completely shut down gas flow. It will also shut down gas flow in the event of an engine over rev or over boost. The system will not switch on until the engine temperature has reached 30 degrees C – this is to ensure LPG does not affect cold starting performance.
Driver Interface
System status is constantly indicated to the driver via dash mount LED panel. If any faults are logged the driver is immediately informed as the system shuts itself down. LPG tank level is also indicated.
Advanced Diagnosis
DieselGas Sequent II constantly logs the last 250 hours of driving. All sensor signals are recorded, as is each LPG tank refill. The system also logs, in real time, each time the vehicle ignition is cycled and each time the DieselGas Sequent II is turned on and off. This ensures faults are quickly detected and the driver alerted. This data also allows us to monitor actual driving conditions to check that the system is delivering the best possible results for you.
Durability and Reliability
The system has been designed to operate in mining, road transport and agricultural conditions. These same requirements are used for all light vehicle installations. The whole system, including the processor and wiring harness, can be submerged in water to 1.2 metres, and has been shock proofed to perform faultlessly in the toughest conditions.
How does it work?
In the application of these systems the diesel system is not turned off and the gas turned on, like a petrol/LPG system, rather the gas vapour is used as a diesel fuel enhancer to help achieve a more complete burn of the fuel in the cylinders and combustion chamber. A common diesel engine only burns around 70-75% of the fuel load in the cylinders. The addition of a complementary amount of LPG helps to achieve a 90-95% cylinder fuel load burn.
Because we are now achieving an extra 20-25% fuel burn we gain extra torque for towing, extra fuel range and savings in running costs. Performance and economy increases of up to 30% are not uncommon.
The systems are non-invasive and require no engine modifications or diesel fuel system modifications. In the event of running out of LPG the vehicle will simply revert back to its normal diesel operation. In most cases the addition of 15-20%t of gas to diesel, by volume ie. 20lt of LPG suits 100lt of diesel.
LPG cylinders are available in a wide range of sizes that may be fitted in many locations that may even enable us to have two, three, or four fills of diesel per tank of gas.
