  • Patent number: 8978599
    Abstract: A control device includes target temperature setting means, feedback control means, and shortcut control means. The target temperature setting means sets a target temperature (?) of a coolant according to a temperature state of an internal combustion engine. The feedback control means controls a control valve in such a manner that a coolant temperature is the target temperature (?). The shortcut control means controls the control valve in such a manner that, when the internal combustion engine is in a cold state, the target temperature setting means sets as the target temperature (?) a warming-up temperature (?) higher than a feedback control temperature (A or B) which is set during feedback control.

  • Publication number: 20150034026
    Abstract: A heat storage device keeps engine coolant hot during operating pauses of the engine allowing quick heating during a cold start of the engine. The capacity of the heat storage device for coolant is twice as large as the capacity for coolant of the coolant circulation system and the engine. An inflow line, an outflow line and a ventilation line pass through the bottom of the heat storage device and are heat insulated on the inside of the heat storage device. Hot coolant from the heat storage device is transferred in two portions into the cold engine. The second portion is transferred when the rising temperature of the metal motor mass has come close to the falling temperature of the first portion of coolant that was circulating in the engine. The heat storage device includes outer and inner containers with a high vacuum in the insulating space between the containers.

  • Patent number: 8925514
    Abstract: A method is disclosed for heating a liquid supplied to an engine of a motor vehicle by a pump when the temperature of the liquid is low, thereby reducing the operating efficiency of the engine. The method comprises inefficient operation of the pump by constricting flow to create heat that is transferable to the liquid. Inefficient operation of the pump is enacted when service brakes are applied and the vehicle is decelerating to minimize negative impact on fuel economy and overall engine efficiency.

  • Publication number: 20140311431
    Abstract: An internal combustion engine is provided. Facing pistons eliminate a cylinder head, thereby reducing heat losses through a cylinder head. Facing pistons also halve the stroke that would be required for one piston to provide the same compression ratio, and the engine can thus be run at higher revolutions per minute and produce more power. An internal sleeve valve is provided for space and other considerations. A combustion chamber size-varying mechanism allows for adjustment of the minimum size of an internal volume to increase efficiency at partial-power operation. Variable intake valve operation is used to control engine power.
