The MIT electromechanical Valve Drive (EMVD) is a continuously variable valve actuation device for an automotive internal combustion engine. Current experimentation of the EMVD has been limited to intake valve events. When the exhaust valve opens into the cylinder it must do so against gas forces arising from high pressure in the engine cylinder. This gas force causes power losses in the EMVD. A gas force simulator has been designed to simulate the pressure acting against the exhaust valve in the engine cylinder. This allows the power loss as a result of the gas force to be measured for the EMVD.
