A convertible cargo body for a vehicle for allowing the user to convert cargo boxes to trailers depending upon the type of cargo being carried. The convertible cargo body for a vehicle includes a cargo body support assembly being adapted to be mounted upon a chassis of a vehicle; and also includes a cargo body assembly including a first box member being securely supported upon the cargo body support assembly and also including a second box member being hingedly attached to and removably disposed upon the first box member; and further includes a wheeled trailer assembly for supporting the second box member.

In a fuel injection system for a multi-cylinder internal combustion engine, a plurality of injection nozzles discharge fuel adjacent the engine inlet ports, and a single injector meters the fuel to all of the injection nozzles. The injector may include an annular valve surface, a plurality of discharge passages opening through the valve surface to direct fuel to the nozzles, and a single valve member associated with the valve surface to control fuel delivery to the discharge passages. The injector may include a rectifier valve that admits air to the discharge passages when the valve member precludes fuel delivery to the discharge passages. The fuel discharge lines that connect the injector discharge passages to the nozzles may be surrounded by air lines.

Fuel injection

In an injector adapted to deliver a charge of fuel and air directly into the combustion chamber of a two-stroke cycle engine, a single solenoid coil has an armature mechanism that sequentially opens both a fuel metering valve and a charge delivery valve.

Solenoid actuated valve assembly

An injector has a single tapered valve controlling fuel flow to a plurality of outlet passages. The entrance to each outlet passage has an orifice surrounded by a raised valve seat. Each valve seat is separated from the other valve seats by a recessed space. The valve pivots as it is displaced from the valve seat to allow fuel flow through the outlet passages, and is constrained against other motion within the injector. The valve seats are clustered beneath the free end of the valve. The orifices are sized to compensate for the unequal lift of the tapered valve from the valve seats.

An electromagnetic fuel injector is provided with a tapered armature valve plate operatively positioned by means of a locator so that it is arranged so as to, in effect, pivot from a spring biased position at which it seats against a valve seat associated with a plurality of orifice discharge passages located concentrically about the axis of the injector to a second position adjacent to the working surface of the pole piece means of the associate solenoid. Preferably, the electromagnetic fuel injector is of the bottom feed type whereby it can be supplied with fuel in excess of the amount to be injected, with the flow path of fuel being arranged so that the excess fuel will purge vapors from the injector and cool the solenoid coil therein.

An edge discharge pulse fuel injector for discharging fuel to the cylinder of an internal combustion engine has a housing with a bore extending axially therein receiving an orifice plate fixed in one end thereof to partly enclose that one end, with the orifice plate having a valve seat surface and an opposed outboard surface with an orifice passage extending therethrough that is located radially outward from the axis of the housing. A solenoid means is fixed in the opposite end of the housing, the solenoid means including a pole piece means with a working surface positioned at right angles to the housing axis and in axial spaced apart opposed relationship to the valve seat surface to define a fuel chamber therewith within the housing which is adapted to receive fuel. An armature valve disc is operatively positioned in the fuel chamber for movement between the opposed working surface of the pole piece and the valve seat surface; and, a spring is operatively associated with this armature valve disc to normally bias it into seating engagement with the valve seat surface. One of the armature valve disc or valve seat surface presenting a surface inclined at an angle to the housing axis whereby the axial movement of the armature valve disc between the valve seat surface and the working surface of the pole piece means is greater adjacent to the orifice passage than at a location 180.degree. diametrically opposite thereof.

Edge discharge pulse fuel injector

A carburetor choke plate is rotated by a driver in one direction from its wide open position for cold enrichment and in the opposite direction from its wide open position for stoichiometric air-fuel ratio control. A fast idle cam limits throttle closure during operation in the cold enrichment mode, and a stop limits movement of the main metering rod toward its rich position in the stoichiometric air-fuel ratio control mode. The choke mechanism also positions an idle bleed valve to vary idle air-fuel ratio, and controls a latch to prevent secondary operation, during both the cold enrichment and the stoichiometric air-fuel ratio control modes.
