The heated mixture is passed through a screen element (30) and traverses a helical path before entry into the intake manifold (50) of the engine. Heating of the mixture to a temperature between 427.degree.-482.degree. C. is disclosed as being advantageous to operation of the engine from the standpoint of noxious emissions.

Abstract: An apparatus is disclosed whereby a sudden perceptible resistance is applied to the accelerator pedal of an automobile vehicle when the intake manifold vacuum pressure level decreases below a preselected pressure. A pneumatic motor is operated by a throttle valve that mixes the ambient and manifold vacuum. The motor controls the relative position of a helical spring relative to the throttle control and allows the throttle control and spring to engage abruptly when the manifold vacuum pressure is below the preselected level and withdraws the spring from contact with the throttle control when the manifold vacuum pressure exceeds that pressure level.

Abstract: Conventional lifter assemblies are relatively expensive to manufacture and generally extend laterally significantly beyond the ends of the roller surface thereof. As a result, fuel pumps utilizing such conventional assemblies must be spaced relatively far apart so that a sufficient roller surface is provided to contact a camshaft. Further, such assemblies are generally relatively heavy, leading to high inertial changes on reciprocation thereof. The ends (42,43 or 142,143) of the roller (14 or 114) are adjacent the inner diameter of the sleeve (28 or 128), whereby the roller (14 or 114) of the resulting lifter assembly (10) extends nearly the full width thereof. A roller holder (30 or 130) fits within one end (32 or 132) of the sleeve (28 or 128) and holds the roller (14 or 114) in a cavity (36 or 136) therein.

Abstract: Rotary engine having a hollow, stationary block with manifolds for air inlet and exhaust valving and means for supplying fuel. The block supports one or more in-line cylinders which are provided with opposed pistons equipped with rigid and constrained piston rods. The rods carry bearings that run along a cam track surface interior to a disc, the outer surface of which is a right circular cylinder. The surrounding right circular cylinder rotates as a result of the linear movement of the opposed pistons thereby providing mechanical power. The cam surface is a continuous track which determines the out-put motion of the piston movement between top and bottom dead center. Arcuate areas at top and/or bottom dead center permit constant volume combustion and/or exhaust as desired during a particular cycle, whether that cycle be Otto or Diesel and whether it be two or four stroke.

Abstract: A carburetion system for metering liquid fuel for supply to an internal combustion engine. Liquid fuel is metered in a single bifurcated metering system by being flowed through a calibrated orifice in response to a proportional pressure reduction which is generated as the result of the summing of a venturi pressure reduction and an auxiliary pressure reduction. Metered liquid fuel is delivered through one branch of the metering system to the engine intake air downstream of the throttle at small and medium engine loads, and through the other branch to the engine intake air upstream of the throttle at large engine loads. Transitioning of fuel flow between the branches is automatic and occurs in response to pressure differences within the system. Fuel delivered to the engine intake air downstream of the throttle valve may be heated or otherwise treated to improve liquid fuel atomization or vaporization.

Abstract: A fuel heater is provided for internal combustion engines utilized on motorized vehicles and utilizing a fuel stored as a liquid. The fuel passes through a frusto-conically shaped coil within a heat exchanger wherein heat is transferred thereto from engine heated cooling fluid which enters the exchanger tangentially and exits axially therefrom.

Preferably, there is also a restriction device for the liquid which sets an initial temperature therein which temperature after setting is generally maintained by cooperation between the pump and the ambient temperature sensitive valve.

Abstract: A preheating system for internal combustion engine fuels. The parts of the system include a heat exchanger through which the fuel passes in heat exchange contact with exhaust gases from the engine, or, in some cases, the engine coolant. Where the heat exchange contact is with exhaust gas, the fuel is vaporized by heat from the gas prior to its introduction into the engine carburetor. Where the fuel passes in heat exchange relationship with engine coolant, it is heated to a point just below boiling before introduction into the carburetor. Where the fuel is heated by exhaust gas, the parts of the system include an accumulator between the heat exchanger and carburetor which serves the purpose of providing a reservoir of the vaporized fuel sufficient to satisfy any demand of the carburetor. The fuel heating system can be employed with a conventional gasoline carburetor where the heat source for the heat exchanger is the engine coolant.
