Cleaner and quieter snowmobiles The University at Buffalo's entry into the Clean Snowmobile Challenge led to modifications of engine, exhaust, body, and electronics to achieve a snowmobile with both lower noise and emissions. Predicting pump dynamics The dynamic behavior of a Parker Hannifin/Abex NWL hydraulic-axial-piston pump was simulated to determine information on pump flow ripple for longer pump life and reduced noise. Electronic engine management for small engines Through an overview of sensor technologies, Cherry Electrical Products confirms that the off-highway industry is ready to benefit from the automotive industry when it comes to electronically controlling small engines. Globally positioning mining vehicles High-tech guidance systems for mining vehicles supplied by companies such as Magellan Corp. are one of the most prevalent uses of global positioning systems in off-highway applications.
