Improve Fuel Economy by up to 50%:
True fuel economy improvement – perhaps up to 50% - is achieved by improving the thermal efficiency of the engine itself using injector rate shaping. While today's modern multiple-injection per combustion event injectors are a clear improvement over older "on/off" solenoid technology, the true thermal efficiency of the diesel engine is still left untapped.
The key to maximum performance of internal combustion piston engines is to match the speed of the motor mechanism to lightning fast combustion. Rudolph Diesel recognized this when he wrote: "...The combustible is added in such a way, that no increase in temperature of the gases, consequent upon the process of combustion, takes place, .... After ignition, combustion should not be left to itself, but be regulated by an external arrangement, maintaining the right proportion between the pressures, volumes, and temperatures."
It has been a formidable technological challenge to achieve what the industry calls a "rate of heat release" that matches Diesel's prescription, particularly for the higher speed engines found in vehicles. Yet to be accomplished, the difficulty of this task has stimulated a field rich in creative innovation. Better control over diesel fuel injection can narrow the gap between the theoretical maximum and actual fuel economy.
Our programmable injector gives the ability to provide a true "rate shape" of fuel flow into the combustion chamber at precisely the speed and proportionality that is required to keep the combustion as close to CT (constant temperature) as possible. This is the ultimate key to increasing engine thermal efficiency and improving fuel economy. Simply put, our injector design introduces heat at the rate at which the engine can convert it into work.
In addition, our programmable injector gives the ability to be used more conventionally in today's applications as it provides the ability to offer double the number of injection events over that of a modern Piezo injector.

Reduce Emissions:
Our technology aids in a sharp start and stop to fuel flow from the injector, reducing NO
x and PM emissions in a way never before possible. When a traditional needle valve opens and closes, the needle is raised slowly at first and then accelerates, and the opposite happens upon closing. It is during these open and close transitions that the fine atomization of fuel becomes "globby", which leads to NO
x and PM formation.
Since our technology removes the needle entirely and replaces it with a spool valve, the open and close events are sharp and precise, thus reducing NO
x and PM formation significantly.

Save Money:
The fastest way to stay ahead of the competition is to implement technology that reduces and eliminates the need for costly emissions scrubbing equipment.
Agricultural engine manufacturers tell us that the cost of engines has increased by 60 to 120% in simply improving their engines from Tier 3 EPA levels to Tier 4 EPA levels. Similar cost increases are seen across the board in the diesel industry from trucking and personal vehicles, all which cost the end customer money. The primary cost driver in these applications is due to expensive aftertreatment equipment such as Urea, Diesel Particulate Filters, Selective Catalytic Reduction, etc.
As manufacturers continue to make their engines emissions compliant using today's technology, the key to success tomorrow is with value added solutions. Programmable fuel injection offers manufacturers a route to build emission compliant and more fuel efficient diesel engines with reduced need to expensive aftertreatment.
