ABSTRACT:
An apparatus for the simulation of variable air pressures, particularly for analyzing the influence of variable air pressures on the exhaust emissions, power output, and fuel consumption of an internal combustion engine includes a canister connected to the engine by way of its intake and exhaust pipes. A vacuum pump is connected with the cannister to withdraw the contents thereof and a throttle valve is associated with a further opening in the canister for regulating the air input to the canister irrespective of the operating conditions and range of the engine. This throttle valve device is formed as a self-regulating throttle device.
