摘要： A stratified scavenging carburetor (1) with a lost motion coupling (29) permits limited relative movement of a throttle valve (2) relative to an air valve (10) so that initial opening of the throttle valve (2) off idle does not open the air valve (10) to avoid diluting with scavenging air the fuel and air mixture delivered to an engine. Rotation of the throttle valve (2) beyond a predetermined amount from idle causes a corresponding opening of the air valve (10) to provide scavenging air to the engine. Closing a choke valve (12) engages a lock lever (20) with the throttle valve (2) to move the throttle valve (2) off idle to a start position without opening the air valve (10). In another embodiment, closing the choke valve (12) prevents the air valve (10) from opening even if the throttle valve (2) is moved beyond where the throttle valve (2) would cause the air valve (10) to open if the choke valve (12) were open. Thus, a richer than normal fuel and air mixture can be supplied to the engine during a choke-assisted start and warm-up of the engine.

摘要： Device which adjusts the combustion of engines during their operations in transitional phases, accelerations, decelerations and changes in the transmission ratios by reduction or suppression of the gas flow through the nozzles of the carburettor, and or by admission, downstream of the carburettor of additional air or exhaust gases, crank-case gases or a mixture of these gases. By its mode of action, the device acts during about75% of the running time of the vehicle in city traffic (case of the ECE 15 cycle). The different embodiments of the device are all characterized by the monitoring system (1-6) controlled by the admission pressure of the engine so that the direction, the intensity and the time of action of the power transmitted to the correcting member (7) be permanently depending on the value of the derivate of that admission pressure with respect to time (POWER = F ((dpa k)/dt) The device may be easily set on any vehicle as an economizer or incorporated in modem combustion systems, conventional or electronic.

摘要： A fuel injection apparatus in accordance with the invention has a hot wire type sensor (28) disposed in a bypass air passage (26) and adapted to sense the flow rate of air in the bypass air passage (26). In order to absorb the pulsation of air flowing in the bypass air passage (26), the bypass air passage (26) opens at its one end to the air cleaner (12) of an intake system disposed in a portion upstream from the hot wire sensor (28). An orifice (32) is disposed in a portion of the bypass air passage (26) downstream from the hot wire sensor (28).
