An engine comprises a combustion chamber and a fuel delivery system which communicates with the combustion chamber and is adapted for connection to a fuel source. The fuel delivery system is operative for pumping fuel into the combustion chamber, and an ignition system is provided for igniting fuel in the combustion chamber. An ignition switch is operatively connected with the fuel ignition system and is operatively movable between an off position for preventing operation of the fuel ignition system and an on position for permitting operation of the fuel ignition system. A priming mechanism operatively connects the fuel delivery system with the ignition switch for operating the fuel delivery system to pump fuel into the combustion chamber simultaneously with movement of the ignition switch between the off position and the on position.
An engine comprising a combustion chamber, fuel delivery means communicating with said combustion chamber and adapted for connection to a fuel source, said fuel delivery means being operative for pumping fuel into said combustion chamber, means for igniting fuel in said combustion chamber, switch means operatively connected with said fuel ignition means and operatively movable between an off position for preventing operation of said fuel ignition means and an on position for permitting operation of said fuel ignition means, and means operatively connected with said fuel delivery means and said switch means for operating said fuel delivery means to pump fuel into said combustion chamber simultaneously with movement of said switch means between said off position and said on position.
An engine comprising a combustion chamber, fuel conduit means communicating with said combustion chamber and adapted for connection to a fuel source, fuel pumping means communicating with said fuel conduit means for pumping fuel through said conduit means in response to a pressure pulse, a source of electrical energy, a spark plug communicating with said combustion chamber for igniting fuel in said combustion chamber, circuit means for conducting electrical energy from said source to said spark plug for operating said spark plug, switch means electrically connected in said circuit means and operatively movable between an off position for interrupting the flow of electrical energy in said circuit means and an on position for permitting the flow of electrical energy in said circuit means, means for generating a pressure pulse in response to movement of said switch means between said off position and said on position, and pulse conduit means operatively connecting said fuel pumping means with said means for generating a pressure pulse.
