An AgWeb.com Farm Equipment Special High diesel fuel costs have driven Case IH to develop new engine engineering to maximize the delivered horsepower from each gallon. The company is introducing its Diesel Saver Auto Productivity Management (APM) system, available on all 2009 Magnum and Steiger tractors.
According to the company’s new product announcement, the Diesel Saver APM will achieve maximum fuel efficiency by automatically adjusting engine speed and transmission ratio across changing load conditions. “The Diesel Saver system not only maximizes fuel efficiency, it actually simplifies the operation of the tractor,” says Tom Dean, marketing director for Case IH tractors. “And it works both on the road and in the field to provide real-world fuel savings, day after day.”
Case IH says the system is easy to use, even for inexperienced operators. In APM system mode, the engine throttle handle serves as a ground speed selector. Once the desired ground speed is attained, the system automatically adjusts engine speed and transmission ratio to provide maximum fuel economy. When the external load increases, the engine RPMs increase and produce more power. When the external load decreases, the engine RPMs decrease, consuming less fuel.
The Diesel saver APM system is able to achieve maximum fuel economy in the Case IH countershaft, full powershift transmission without the use of additional hydrostatic motors which can cause parasitic efficiency losses, especially in heavy tillage applications.
