A work vehicle includes a hood, an engine, a radiator, an air cleaner, and a condenser. The hood covers an engine compartment located on a front portion of a traveling body. The engine is a drive source. The radiator supplies a coolant to the engine. The air cleaner takes in outside air and supplies the air to the engine. The condenser cools a refrigerant. In front of the radiator, the air cleaner and the condenser are disposed one above the other. The condenser is withdrawable in the left and right direction.

An object of a control method to control a direct injection internal combustion engine that directly injects fuel in a cylinder is to reduce an increase in PN caused by attachment of the fuel to a fuel injection valve distal end. The control method cools the fuel before a fuel temperature when the fuel passes through an injection hole on a fuel injection valve reaches a temperature at which an amount of attached fuel to the fuel injection valve distal end increases.

The invention relates to an environmentally friendly motor vehicle based on the use of energy-accumulating substances (EAS) and can be used not only in transportation engineering, but also in power engineering to produce electric power with the aid of thermal engines run on hydrogen that is produced from aluminum composites in reaction with water. The object of the invention is to provide an environmentally friendly motor vehicle powered by hydrogen that is produced from EAS, comprising a closed water supply system to supply a reactor of a hydrogen generator with water obtained by condensing water vapors from exhaust gases, and quick change cartridges composed of a cylinder casing and a cover with hydrogen-generating elements in the form of plates of aluminum composites mounted inside the casing. The object is attained in the following way. A motor vehicle comprising an internal combustion engine provided with a liquid cooling system with a primary radiator mounted in front of the engine, and a hydrogen generator accommodated in a trunk and operating on the reaction of aluminum composites with water, further comprises an exhaust gas cooling system to autonomously supply the generator with water by condensing water vapors in exhaust gases. The exhaust gas cooling system is connected to an exhaust manifold of the engine and consists of an expander, a condenser in the form of a gas/air heat exchanger and a storage tank for collecting water condensate and discharging uncondensed gases. The storage tank is connected by means of conduits to the hydrogen generator, wherein the supply of water to the latter and circulation of water in order to intensify the hydrogen release process are performed by a pump mounted inside the storage tank, and drainage of water from the generator into the storage tank is performed through a filter mounted in the generator housing.

A fuel heating apparatus including a heat exchanger body having a first removable end plate, a main body, and a second removable end plate opposite the first removable end plate. The first and second removable end plates are secured to opposing sides of the heat exchanger main body by a plurality of threaded fasteners. The first removable end plate includes a fuel inlet line and a thermal fluid inlet line, and the second removable end plate includes a fuel outlet line and a thermal fluid outlet line. The main body includes a plurality of interior first fluid pathways and a plurality of interior thermal fluid pathways defined therein, the interior first fluid pathways being responsible for connecting the fuel inlet line to the fuel outlet line and the interior thermal fluid pathways being responsible for connecting the thermal fluid inlet line to the thermal fluid outlet line.

The present invention is a system and method for modifying an engine for use with an alternative fuel that needs to be conditioned. Coolant is diverted from the original engine heater core and is used to heat or condition the alternative fuel both in the alternative fuel tank and in a special manifold that heats and circulates the fuel before delivering it to the engine. An electronic control unit monitors the temperature and pressure to ensure proper viscosity and engine operation.

An object of a control method to control a direct injection internal combustion engine that directly injects fuel in a cylinder is to reduce an increase in PN caused by attachment of the fuel to a fuel injection valve distal end. The control method cools the fuel before a fuel temperature when the fuel passes through an injection hole on a fuel injection valve reaches a temperature at which an amount of attached fuel to the fuel injection valve distal end increases.

A heat recovery structure includes a pipe portion, a heat exchanging portion and an actuator. The pipe portion is inclined such that a side face of the pipe portion faces a diagonally lower side, and is configured such that exhaust gas from an engine circulates through the pipe portion. The heat exchanging portion is configured to communicate with the pipe portion and to perform heat-exchange between a heat medium and the exhaust gas flowing into the heat exchanging portion from the pipe portion such that the exhaust gas thus subjected to the heat-exchange with the heat medium flows out to the pipe portion. The actuator is configured to operate a selector valve configured to switch between a state where the exhaust gas circulates through the pipe portion and a state where the exhaust gas circulates through the heat exchanging portion.

A cooling module for use with an internal combustion engine having separate cooling circuits, the cooling module having a cuboid shaped structure having walls defining an internal open portion, at least one of the walls comprising a low-temperature heat exchanger circuit and one of the walls comprising a high-temperature heat exchanger circuit and a fan located within the open portion of the structure and enclosed by the walls. The fan is configured to act as a sucker fan to draw air from outside the structure through the at least one low-temperature heat exchanger circuit and to act as a blower fan by redirecting the air out of the structure through the at least one high-temperature heat exchanger circuit. The cooling module has increased fan efficiency, reduced noise, and optimal functional heat exchanger face area per given space.

A temperature control device for the engine may include an air heater configured to heat air introduced into a throttle valve by a flow of engine cooling water, and a valve apparatus configured to cut off the flow of the engine cooling water passing through the air heater at a set temperature range or more, without being supplied with a separate control signal.

Disclosed is a method for limiting fuel leakage from at least one injector in an engine of a motor vehicle, the engine being stopped and the motor vehicle ignition circuit being switched off, the injector being supplied with fuel via a fuel rail which is pressurized during operation, the pressurization persisting for a certain period when the engine has been stopped and the ignition circuit switched off, leading to leakage of fuel through the injector. The injection rail is subjected to forced cooling following the stoppage of the engine with the motor vehicle ignition circuit switched off, which is sufficient to reduce the pressure, the forced cooling continuing until the pressure in the rail is close to atmospheric pressure.
