Combustion air warming system for internal combustion engine

The system involves warming the combustion air to a pre-set temperature in a heating line string (5) parallel to the induction manifold (2). This occurs during a pre-warming phase before starting the engine (1) by means of a heating device (4). A sector (2b) of the induction manifold and of the heating line string form a closed circuit during the pre-warming phase, in which the combustion air heated in the heating device is circulated in the opposite direction to that of the air induction (17).

Preheating system for IC engine - stores waste heat as latent heat and uses salt solution changing from crystalline to liquid form releasing heat to oil circuit

The preheating system for an internal combustion engine stores the waste heat obtd. when the engine is in operation. It uses a latent heat store, which functions as a heat exchanger to supply or absorb the necessary energy. It also includes a switch to release the required heat. The latent heat store is incorporated in the coil circuit. The latent heat store (6) uses a salt solution, which changes from a crystalline form to a liq. form thus releasing the latent heat. The heat is given off to the coil circuit of the engine via the oil pump (4) driven by a motor (15), which pumps lubricating oil whose viscosity will be reduced. This will therefore reduce the consumption of the starter.

TEMPERATURE CONTROL FOR TURBOCHARGED ENGINE

A cooling apparatus (10) and method for a turbocharged internal combustion engine (12). The combustion air (16) exiting a turbocharger (18) is passed over an air-to-water intercooler (40) then over an air-to-air intercooler (42) for heat exchange with liquid coolant and with ambient air (32) respectively. During periods of low ambient air temperature, the combustion air may be directed through a bypass duct (80) around the air-to-air intercooler, and further, may be heated by the coolant in the air-to-water intercooler. A multi- speed fan (44) and/or shutters (48) may be used to control the flow of ambient air across the air-to-air intercooler. A cooling duct (68) provides a flow of ambient air to the fan motor (46) during periods of operation when the flow of ambient air over the air-to-air heat exchanger is restricted by the shutters. Coolant exiting a subcooler (28) has the lowest temperature in the system and is directed to a lube oil cooler (34) for engine lubricant cooling.

FUEL/AIR MIXING USING SWIRL CHAMBER

TITLE "FUEL/AIR MIXING USING SWIRL CHAMBER" An air/fuel homogenising means for use downstream of a carburettor and upstream of the intake to an internal combustion engine to more effectively homogenise and/or otherwise the entrainment of the fuel in the air stream from the carburettor. The homogenising means comprises means defining a swirl chamber into which the air/fuel mix enters tangentially of the swirl to be created therein and from which it exits axially of the swirl created therein. The boundary or at least a portion thereof against which the swirling fuel/air mix impinges or passes is heated to a temperature above ambient temperature or at least the temperature of the fuel/air mix to assist in vapourisation. Such heating is preferably carried out with the use of a fluid jacket which receives either exhaust gases or coolant from the engine.

DEVICE THAT IMPROVES THE PERFORMANCE OF A PORTABLE ENGINE POWERED TOOL DURING WINTER CONDITIONS

Engine-driven portable tools are widely used for different kinds of work where the surrounding conditions are very different. Large variations in temperature can cause problems for the engine, especially durring low temperatures that occur during winter. The present invention reduces these problems in a simple and effective way by guiding heated air from the area adjacent to the muffler through a channel placed outside the casing to the air inlet for the engine. The cold air sucked into the engine is mixed with the heated air from the channel so that the temperature of the air mixture is increased.

METHOD AND APPARATUS FOR DUAL FUEL INJECTION INTO AN INTERNAL COMBUSTION ENGINE

Two different fuels are injected into the combustion chamber of an internal combustion engine. A main fuel is ignited by a pilot fuel that is more readily auto-ignitable than the main fuel. According to the method, load conditions on the engine are monitored and sets of conditions are defined to constitute low load conditions and high load conditions. Distinct operating modes are defined for each set of load conditions. Under low load conditions, a homogeneous mixture of main fuel and air is too lean to ensure stable combustion; consequently, the main fuel is injected at high pressure immediately following injection of the pilot fuel. Under high load conditions, fuel is injected in three stages. In the first stage, the main fuel is mixed with intake air prior to introduction into the combustion chamber or the main fuel is injected during the intake stroke or early in the compression stroke.

System connected to the air filter, for improving the liquid cooling of internal combustion engines

Système d'utilisation du flux d'air frais aspiré par les moteurs à combustion interne à refroidissement liquide lors de leur fonctionnement. Ce flux d'air devient alors un élément permettant d'abaisser la température du liquide de refroidissement. Il suffit pour cela de placer un échangeur thermique 1 sur le chemin du flux d'air aspiré par le moteur 5. C'est-à-dire entre l'entrée du boîtier de filtre à air 3 et le carburateur 4. Ce système permet en toutes circonstances, même à faible vitesse ou à l'arrêt du véhicule, sans faire appel à un ventilateur, d'obtenir un excellent refroidissement. Ce système convient (entre autre) parfaitement aux motocyclettes vouées à un usage tout terrain, toujours à la recherche de gain de poids, d'encombrement, d'efficacité, et de fiabilité.
