Medina, MN —Polaris has introduced the 500 High-Output engine for its Sportsman 500 ATV. The powerplant is a liquid-cooled, 4-valve, 4-stroke Polaris 500 engine with counter balance.
The power is managed by the Dual-Sensing automatic PVT (Polaris Variable Transmission) with the Polaris EBS (Engine Braking System). The PVT requires no shifting and is a dual-sensing transmission that responds to both engine RPM and vehicle torque requirements. EBS utilizes engine compression for braking.
When additional traction is needed, the on-demand 4-wheel drive system is engaged. The system senses when the rear wheels lose traction and start to spin, then automatically engages both front wheels, providing torque to all four wheels. Other systems only engage one wheel, making it 3-wheel, rather than 4-wheel drive.
In many engineering workplaces, there’s a generational conflict between recent engineering graduates and older, more experienced engineers. However, a recent study published in the psychology journal Cognition suggests that both may have something to learn from another group: 4 year olds.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
