A heating device for heating an item such as a carburetor uses a first PTC heating element 12 positioned compactly within a housing 10 which is directly adjacent the item to be heated. A Second PTC element 14 having a great electrical resistance increase at a prescribed temperature level is also compactly contained in the housing and is electrically connected in series to the first PTC element 12. This second PTC element 14 restricts the electric current flow through the device when the ambient temperature exceeds the prescribed temperature level.

Heating device for an internal combustion engine with PTC elements

A fuel supply control device for an internal combustion engine in which fuel is injected from a fuel injection device (6) in an intake port (2.1) and air that flows into the intake port is mixed with the injected fuel to be supplied to combustion chamber (1) is shown, in which there are provided an intake control valve (20, 30) having a heater (7.3, 7.4) in the intake port and being capable of opening and closing the mixed gas flow passage. Control circuits (12, 13) carry out opening and closing position control of the intake control valve (20, 30) so that, at least during the time when the heater (7.3, 7.4) generates heat, the portion of the heat-generating region of the intake control valve (20, 30) may be located in the fuel injection range, with the valve (20, 30) functioning as a variable heater, variable intake valve and an AD port.

Fuel supply control device for internal combustion engines

A heating device for injected fuel in an internal combustion engine is disposed at an upper wall of an intake port. The heating device includes a casing and a plurality of fins integrally connected to a lower plate of the casing. A heater is disposed between the intake port and the casing. The fins are arranged to downwardly extend from said supporting member and along the injected direction of the injected fuel. Therefore, the atomization of the injected fuel is accelerated by the heating of the heating device.

Heating device for injected fuel for internal combustion engine

A heating system using a heating device 1 with a positive temperature coefficient thermistor 10 (PTC) is disclosed for the purpose of warming a carburetor/throttle body of an internal combustion engine and a timer device 20 using the PTC 10 for its control.

Heating device and system for an internal combustion engine

This invention relates to a fuel heating device for internal combustion engines, in which both fuel heating means and fuel conductance passage are accommodated in the main body, constructed in such a manner that the fuel is injected after being heated while it passes the aforementioned fuel conductive passage to be arranged proximate to the combustion chamber of the internal combustion engine.

Fuel heater for internal combustion engines

A thermally and electrically conductive housing having a solid tip portion is shown mounting a heating element thermally and electrically coupled to the tip portion which in turn is electrically coupled to a switch mechanism mounted within the housing. The switch mechanism includes a thermostatic snap acting disc adapted to bias a movable electrical contact away from a stationary electrical contact at preselected temperatures. The housing is shown mounted in a carburetor of an automobile to contact energization of a honeycomb heater disposed in the carburetor, however; the device can be used in other locations where it is desired to maintain a body within a selected temperature range.

Heating device

A fuel supply device and heating device or system for an electrically controlled fuel injection engine has an air intake and a fuel injector arranged to direct air and fuel respectively into a cylinder inlet passageway leading to a cylinder inlet valve opening in an engine cylinder and has a heating device located in the passageway having a heating surface arranged to receive fuel from the fuel injector for heating the fuel and deflecting it or directing it into the cylinder through the cylinder inlet valve opening substantially free of condensing contact with walls of the passageway, thereby to assure that the proper ratio of air and fuel as provided by the electronic controls of the engine are properly received in the engine cylinder.
