Abstract: An internal combustion engine generally utilizes a conventional four stroke process including an intake stroke, compression stroke, expansion stroke, and exhaust stroke and in addition to this four stroke process, adds a secondary process having two additional strokes for scavenging the combustion chamber with fresh air. This two stroke scavenging process employs a fresh air intake stroke and a fresh air exhaust stroke to exhaust any remaining burnt and unburnt gases from the combustion chamber.

Abstract: A manifold depression responsive fuel pump has its fuel outlet connected to an automatic cold start air/fuel mixture supply device, and a movable stop, which limits movement of the pump diaphragm to enlarge the fuel chamber, has its position controlled by the engine temperature responsive thermostatic control mechanism of the cold start device. The pump diaphragm carries a shut-off valve opposite the pump fuel inlet. Fuel is pumped into the cold start device by the pump when the carburetter throttle valve is opened before the engine has warmed up to normal working temperature. The movable stop is moved towards the pump fuel inlet, as the engine warms up, and seats the shut-off valve in that fuel inlet when the engine has warmed up to its normal working temperature so that the pump does not function to pump fuel into the cold start device once the engine has warmed up to its normal working temperature.

Abstract: An acceleration pump delivers additional fuel to both the main intake passage and the auxiliary intake passage of an internal combustion engine, to facilitate cold starting. In such an engine, each main combustion chamber is in communication with an auxiliary combustion chamber, respectively. Coordinated means are provided for operating said acceleration pump and throttle valves in said intake passages. Communication between the acceleration pump and the main intake passage remains open at all times, but a passageway connecting the acceleration pump and the auxiliary intake passage is closed except when the ambient temperature is low. Closure of the connecting passageway is effected automatically or in coordination with operation of the choke valve for the main intake passage.
