Fuel injection type engine

Abstract

Abstract PURPOSE:To enhance the starting characteristics of a fuel injection type engine by controllably injecting a given amount of fuel from an injector provided to an air inlet manifold prior to the start of cranking. CONSTITUTION:In an engine in which an injector 3 provided to an air inlet manifold 2 is controlled by a control circuit 4, output signals from an air flowmeter 5, a throttle sensor 6, a distributor 7 and a water temperature sensor 8 are put in the control circuit 4 where an optimum fuel amount is calculated, and the fuel injection signal is sent out to the injector 3. In this case, from the control circuit 4, when an ignition switch 10 is turned, an injection signal of a given time (t) is outputted to the injector 3, and when the ignition switch 10 is turned thereafter, cranking is allowed to be made. By this, during the cranking period, an enriched mixed gas is supplied to the engine 1 and the smooth startup of the engine is thus made possible.
