A hybrid electric vehicle (HEV) for multiple operation modes includes: a gasoline diffusion flame (GDF) combustion engine configured to perform gasoline diffusion flame combustion; a motor-generator operatively connected to the GDF combustion engine and configured to selectively drive the HEV with electric power of a battery or generate electric power to charge the battery; and a multi-mode controller including a processor and configured to receive operating conditions of the GDF combustion engine and the motor-generator and define a plurality of mode operating regions based on the received operating conditions. In particular, the plurality of mode operating regions includes: an electric vehicle (EV) only mode operating region, a GDF mode operating region where the GDF combustion engine operates and drives the HEV while the motor-generator stops, and a GDF+EV mode operating region where the motor-generator assists the operation of the GDF combustion engine to drive the HEV.

A coolant flow control system () includes an integrated coolant flow control and heat exchange device (). The device includes a valve body part () and a heat exchange part (). According to the system, all the coolant flow from the engine is delivered back to the engine after passing through the valve body part () and then the heat exchange part () in which it passes over the heat exchanger part (). The valve body part () by positioning of the coolant flow wall () allows multiple flow modes and coolant paths to branch out (or converge) from (or to) thereby controlling the flow in all coolant circuit branches.

Integrated coolant flow control and heat exchanger device

A coolant flow control management system includes an integrated pump coolant flow control and heat exchange device for delivering engine coolant to and from the engine. According to the system, coolant flows from the engine and is delivered back to the engine after passing through various coolant branches while flow is regulated by a control valve part of said device, then passes through a heat exchanger part before being returned to the engine by a pump part. Systems of the invention are particularly useful with all-electric and hybrid vehicles.
