摘要： A method to control the combustion of a compression ignition engine having the steps of: establishing, for each combustion cycle, a fuel quantity to be injected into the cylinder; injecting a first fraction of the fuel quantity; heating a second fraction of the fuel quantity, which is equal to the remaining fraction of the fuel quantity, to an injection temperature higher than 100° C.; injecting the second fraction of the fuel quantity heated to the injection temperature into the cylinder at the end of the compression stroke and at no more than 60° from the top dead centre; and decreasing the injection temperature and the ratio between the second fraction and the first fraction as the internal combustion engine increases and as the rotation speed of the internal combustion engine increases.

摘要： A fuel heating apparatus for an internal combustion engine or other type of spark ignition engine having an associated pressurised fuel delivery system, the apparatus comprising a chamber for receiving a volume of a pressurised liquid fuel; and means for heating the fuel within the chamber to provide heated liquid fuel to the fuel delivery system of the engine, to thereby minimise condensation of the fuel and facilitate ignition of the engine within relatively low ambient temperature environments. The apparatus has particular application with ‘heavy fuels’, such as diesel or kerosene, and improves the reliability and performance of the engine especially during ‘cold starts’ and while transitioning to fast-idling.

摘要： An air heater for heating air entering a combustion chamber of an internal combustion engine is disclosed. The air heater includes a heating element having a substantially planar portion and a flange portion. The flange portion is positioned at an angle to the planar portion. The planar portion is positioned within an air flow at an upstream location relative to the flange portion. A structure is operable to position the heating element in communication with the air entering the combustion chamber of the engine. In addition, a thermal expansion joint for interconnecting a heating element and a frame is disclosed.

摘要： A heating element for a fuel tank takes the form of an immersion heater commonly used in process applications to heat the contents of a fuel tank. The heater would be encased within a well for ease of servicing and replacement as well as safety. The tank heater would be wired in parallel with an engine block heater and connected to a suitable power cord, which would be plugged into a receptacle powered by alternating current. This feature allows the energizing of two heaters from only power cord and is identical to the procedure followed for only the block heater. The thermostat would be provided with an operating thermostat to keep the diesel fuel at the proper temperature, as well as an over-limit termination device for safety purposes.

摘要： 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.

摘要： An intake manifold of an internal combustion engine is structured either to keep the temperature in the intake manifold constant or to allow the temperature in the intake manifold to be controlled from outside thereof for thereby increasing the engine output. For this purpose, following measures are employed:(1) The intake manifold is made of a material having a low heat conductivity;(2) The outer periphery of the intake manifold is covered with an adiabatic material;(3) The intake manifold is of a double walled structure; and(4) The intake manifold is provided with a cooler or a heater.
