Abstract
Engine acceleration detection apparatus comprising a diaphragm unit with a first chamber connected directly to a point downstream of a throttle valve in a carburetor, a second chamber connected to the same point through a delay element, a diaphragm which is provided between the first and second chambers and is displaced and causes displacement of an actuation rod element to actuate regulation means for adjustment of exhaust gas recirculation or other factors relating to engine operation when pressure increases downstream of the throttle valve, and atmosphere connection means which renders the diaphragm unit inoperative by connecting the second chamber thereof to the atmosphere in certain operating conditions, such as acceleration from high speed.
