Small engine EFI is not new anymore.
More and more small engine manufactures switch from carburetors to EFI either because of the more stringent emission regulations or the market demand for better products. EFI has a lot of advantages over the carburetors, as it has been proved by auto industries.
One major hurdle for small engine EFI applications has been the cost. The add-on cost of the EFI system has been prohibiting to the OEMs to replace the carburetor. This problem can be mitigated by mass-production of the EFI components. However, there are a lot of small engine applications that do not meet this prerequisite of large volume production. Those applications can be very specific to certain niche markets, like racing bikes, go-carts, ATVs, tractors, mowers, even model air planes. Further, these small engine applications are quite different from one to another, as you can see.
Market has been demanding a low-cost, flexible EFI kits for those small engine applications. And we are responding to it. We, ECOTRONS, are the manufacturer of small engine EFI systems. Our products include the small engine ECUs, small engine EFI conversion kits, Accurate Lambda Meters (ALM), and even a small engine simulator (SimMotor).
The unique advantage of our products is flexibility. We develop the customized small engine EFI system for small volume customers in a very short time and with very low development cost. How do we do it? by using the state-of-art technologies like: scalable semiconductors, and model-based-designs, etc. You don't have to know what they are, and you just need to know: when the technology and manufacture meet, they suppose to speed up the development and reduce the cost. That's exactly what we do.
Our current product lines include: 2-stroke small engine EFI kits, 4-stroke small engine EFI kits; supporting 1-cylinder or 2-cylinder engines, whether they are in-line 2 or V-2, or symmetric 2-cylinder engines.
Our 2-storke EFI kits support 1 or 2 injectors per cylinder, and the 2 injectors can be one small and one big, to cover the low idle RPM all the way up to 16000RPM.
Our 4-stroke EFI kits can be full Plug-And-Play (PNP) kits by using the O2 sensors, as our ECU has a very sophisticate algorithm of self-tuning based on the close-loop controls. Got a wideband controller? That's even easier to do self-tuning with our ECU.
You've got 2-cylinder engines which require a 2 bank control system (each cylinder has its own O2 sensor). No problem. We have it in stock.
Our EFI kits can run the engines with displacements from 35cc all the way up to 1200cc. Because we have different sizes of injectors (38, 60, 80,128, 200 g/min flow rates, and more.) We have variant size of fuel pump too, (10 to 100L/H volume flow rates). Mainly the missing part here is the throttle body. Right now, we don't have all kinds of throttle bodies. But the good news is a lot of customers can get their own throttle bodies off the shelf. Or they have the capability to manufacture their own or adapt to the exiting throttles.
What is the only thing that really blocks the small engine EFI? There is probably none except people's mindset.
