John Deere - Model 550K - Crawler Dozer Intelligent Engine Technology Brochure

Increased power and torque, using fuel injection optimization. Precision. Achieved. Steinbauer. The desired performance enhancement is achieved by changing the injection duration, the same way the system was originally designed to operate. This also allows precise fuel control throughout the full rpm range of the engine. Injection duration is achieved by adding pulse width to a signal, (i.e. at end of injection). This is not changing timing—that’s best left to the factory ECU. Our module also does not interfere with common rail pressure - making our module the best choice for your engine.
