The pressure of the incoming oil controls the rate of injection by controlling the speed of the intensifier piston and plunger movement. The amount of the fuel injected is determined by the duration of the pulse from the Electronic Control Module. Only Cat HEUI fuel systems can control injection pressure, injection timing, and injection rate electronically. Heat treated by a patented hardening process for high strength and outstanding wear characteristics. Journals are finish-ground and polished assuring ultimate smoothness for less internal friction and long bearing life.
All crankshaft are precision balanced, both statically and dynamically to provide long life.
Front and rear crankshaft seals have wear sleeves to provide increased crank reusability. Of all the stages in engine management, maintenance has the greatest impact on your bottom line. A regular maintenance program leads to less downtime, better machine resale value, and fewer failures. Working together, we can maintain peak engine performance, maximize component life, and lower operating costs. Cat Engine Parts are built robust.
