A fan shroud assembly according to an example of the present application includes an air intake duct configured to receive ambient air, a fan configured to receive hot air, a motor driving the fan, and an air induction intake box in fluid communication with the fan and the air intake duct to mix the hot air and the ambient air. A vehicle and a method of providing cooling air to a vehicle engine are also disclosed.

A method of operating a forced induction gaseous-fueled engine includes mixing gaseous-fuel and engine intake air to form a mixture at a fuel mixer. The method includes delivering the mixture to an intake manifold by at least partially bypassing a charge air cooler.

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 cooling system for an internal combustion engine comprises a fluid circuit having an intercooler, a main cooler and a precooler. The intercooler is configured for receiving coolant and configured for heat exchange relation between the coolant and engine compressed air. The main cooler is configured for receiving the coolant from the intercooler and the internal combustion engine and configured for selectively delivering a first portion of the coolant from the main cooler to the precooler. The precooler is configured to deliver a flow of the coolant to the intercooler. The main cooler and the precooler are configured for cooling the coolant by heat exchange with at least one cooling flow.

A charge air cooler shroud mounting system is provided. The charge air cooler shroud has a body having a four point attachment system including a mounting aperture, a first lug, a second lug and a third lug. The mounting aperture provides a fixed point of attachment while the lugs provide a plurality of floating points of attachment.

An air filter device for a motor vehicle is provided with a filter housing having an air inlet and an air outlet, a filter insert which is received in the filter housing and divides the inside of the filter housing into an untreated air section and a pure air section, and a bypass line for supplying air into the untreated air section. The bypass line extends from a connection opening in the filter housing to a cooler, especially a charge air cooler of the motor vehicle.

A rear spoiler arrangement is provided for a motor vehicle having a rear mounted engine, an intercooler for the rear mounted engine and a holding member for a spoiler apparatus being provided in a rear region of the motor vehicle. In each case at least one opening is provided in the spoiler apparatus and the holding member as an air guide to the intercooler. The rear spoiler arrangement includes an air guiding arrangement with at least one air guiding slat provided at least in the opening of the spoiler apparatus.

This diesel engine comprises: an engine body part in which a cylinder head is fastened to an upper section of a cylinder block; a turbocharger; and an exhaust gas post-treatment device. A cooling fan is provided on the front side in the front-rear direction of the engine body part. The cylinder head is configured to have an exhaust side on the left side in the engine width direction, and an intake side on the right side. The exhaust gas post-treatment device is disposed above the cylinder head so as to extend in the engine front-rear direction. The turbocharger is disposed on the exhaust side of the cylinder head and is configured to spray compressed air in the engine front-rear direction.

An integrated air shroud assembly is provided for a motor vehicle. That air shroud assembly includes a body having a radiator opening, a charge air cooler opening and a cooling fan opening. The charge air cooler opening is offset from the radiator opening and the radiator opening and the charge air cooler opening are in parallel communication with the cooling fan opening.

A cooling system is provided for an engine. The cooling system may have an air cooler configured to cool intake air being supplied to the engine. The cooling system may also have a sensor configured to generate a temperature signal indicative of a temperature of the intake air and a fan in proximity to the air cooler. The cooling system may further have a controller in communication with the sensor and the fan. The controller may be configured to cause the fan to operate at a speed that is a function of the temperature signal when the temperature of the intake air is above a threshold temperature. The controller may further be configured to selectively cause the fan to pulse when the temperature of the intake air drops below the threshold temperature.
