摘要： An intake air filter box utilizing an intake air heater that inhibits the buildup of snow and ice within the intake air filter box, keeping the associated flow passages clear such that pressure loss is not adversely affected. This intake air heater can include an electric heater or a radiant heater coupled to the exhaust gas recirculation (EGR) system of the vehicle, or to another source of heated fluid. Preferably, the intake air heater is disposed on the “dirty” side of the filter disposed within the intake air filter box, adjacent to the intake air conduit and air intake of the vehicle. This is where the snow and ice accumulation occurs. A drain is provided in the bottom of the intake air filter box housing to allow the escape of water from the melted snow and ice, ensuring that this moisture is not delivered to the turbocharger and engine with the intake air.

摘要： The system is applied to an engine (M) having an injection system, a fuel feed line and a cooling system (CS), by means of a cooling fluid which circulates, through hot fluid ducts and cold fluid ducts, through the engine (M) and through a heat exchanger. The feed line has a first segment, connected to the injection system and provided with a first valve, to be closed when the fuel temperature is below a maximum value, and open when the fuel temperature reaches the maximum value. The feed line also has a second segment derived from the first and absorbing thermal energy from the hot fluid duct or from the combustion gases and provided with a second valve which remains open while the fuel temperature is lower than the maximum value, and which is closed when said temperature reaches the maximum value.

摘要： Free heat or scavenged heat from the coolant system or circulating oil from the crankcase of an internal combustion engine supplies heat to a fuel pre-heater causing the liquid fuel to become superheated and partially vaporized. Liquid fuel preferably diesel is converted from a fluid at ambient temperature to a superheated fuel breaking down the hydrocarbons bonds of the fuel (cracking) before being sent directly to the fuel injectors. Water fog may be added to the air intake manifold. Catalysts inside the fuel preheater also aid in breaking down the fuel (cracking). The fuel pre-heater also operates as a coolant/oil filter to remove debris and sludge from the circulating coolant water or circulating crankcase oil of an internal combustion engine. Fuel efficiency has repeatedly been tested to increase 20% or better with highway driving. Exhaust emissions have been tested to show 20% or more reductions in greenhouse gases.

摘要： The system is meant to heat the intake air in internal combustion Diesel engines and is based on the use of a resistor having two segments (1) and (1′) joined to each other on one end (2), the segments (1) and (1′) being made of different metal alloys to form a thermocouple that allows using the module determined by this resistor with a control circuit to automatically regulate the temperature of the intake air, as well as to know the flow rate entering each cylinder from a measurement of the amount of heat supplied to the air flow entering each cylinder of the engine. The system will be disposed in correspondence with the intake duct (4) of the corresponding engine cylinder (3), where the union (2) of the segments (1) and (1′) which form the resistor must be located at the center of said duct (4), where the air flow is greatest.
