A controlling method of vehicle exhaust gas recirculation, an apparatus and an electronic device are provided in vehicle field. Before the GPF/DPF starts to work, controlling the EGR to cool the temperature of the recycled gas at a lowest gas temperature required being entranced into the engine; and after the GPF/DPF starts to work, according to a gas temperature change and an intake flow change of an air intake of the EGR, adjusting an opening of a valve arranged in a vent of the EGR and a working power of a pump arranged in a liquid duct of the EGR, for making the EGR to cool the gas recycled by the EGR in a safe temperature range required by the engine. The controlling method is associated controlled with a cooling system of the EGR, for ensuring the recycled exhaust gas temperature and the EGR rate in a suitable range.

In a header plateless type heat exchanger, to suppress temperature rise at an apical portion of a tube into which exhaust gas at high temperatures or the like flows, to thereby improve durability. A recessed groove portion 4c recessed inward with narrow width is formed on outer face side of each of a pair of plates, in parallel to a swelling portion 4 and in the approximately same length.

An EGR cooler 5 is attached to an engine 1 via a bracket 6. The bracket 6 has an exhaust introduction path 65 for introducing some exhaust discharged from a cylinder head 11 to the EGR cooler 5, an exhaust recirculation path 66 for recirculating exhaust that has passed through the EGR cooler 5 toward the engine 1, a cooling water introduction path 67 for introducing cooling water from cooling water supply parts (3, 13-15) to the EGR cooler 5, and a cooling water recirculation path 68 for recirculating cooling water that has passed through the EGR cooler 5 to the cooling water supply parts.

Methods and systems are provided for adjusting a location of a fuel injection in response to a substitution rate and a desired EGR flow. In one example, a method may include injecting a first fuel to a combustion chamber via a direct injector positioned to inject directly into the combustion chamber, injecting a second, different, fuel to the combustion chamber via an exhaust port injector positioned to inject toward an exhaust valve of the combustion chamber, and combusting the first and second fuels together in the combustion chamber.

An exhaust gas recirculation (EGR) cooler for mounting to a coolant collector bracket may include a cooler body having a top, a bottom, a length extending in a longitudinal direction, and a width extending in a lateral direction perpendicular to the longitudinal direction, and at least one mount coupled to the bottom of the cooler body. An interior of the mount may be in fluid communication with an interior of the cooler body. A width of the at least one mount in the lateral direction of the cooler body may be equal to or less than the width of the cooler body. The at least one mount may be positioned such that the mount does not extend beyond the width of the cooler body.
