Evap system trainer

The EM-200-22 EVAP trainer is designed as a functional evaporative emissions system based on a Chevrolet Cobalt platform. It can be used to teach the operational functions of a typical evaporative emission system. It also has the capability of demonstrating the cause and effect of having a small and/or large system leak. Students are able to visualize the components of the system and can hookup test equipment to learn how system leaks will affect performance. The fuel tank contains an internal lamp heater for demonstration of internal pressure changes. Requires a 12 VDC power supply to operate.FIND OUT ABOUT ELECTUDE COURSEWARE FOR EM-200-22
