  • Electric Clutch Used on Engine Cooling Fan Helps Save Energy and Improves Mileage
    On-off fan controls aren't ideal for all applications. Lift trucks and skid loaders, for example, tend to cycle on-off clutches more frequently because such vehicles always need some amount of engine-fan cooling. Two-speed fan clutches work better in these applications. Such clutches have embedded
  • A fan of fuel savings
    connects to a valve that directs fluid to a fan clutch. High temperatures engage the clutch and low ones disengage it -- well, almost. Engaged viscous-coupled fans typically slip about 5 to 10% of shaft speed. And disengaged fans may still run at about 45% of engaged speed, especially at low engine rpm
  • Are Hydraulic Fan Drives For You?
    engine speed, not cooling demand. This means belt-driven fans usually deliver too high or too low an air flow, which not only causes wide fluctuations in engine temperature, but wastes power. Maximum power is lost when the engine (fan) runs at high speed, even though little cooling may be needed
  • Engine Header Coating Comparison
    Coatings on high-temperature exhaust manifolds and headers have been shown to increase engine performance in some racing applications. Are all coatings equal? What is the effect of having this procedure done on exhaust components? Three different coated tubular headers have been put to the test

While simple shot peening has long been considered an obvious option, spectacular improvements in damage tolerance have been demonstrated through
