Low-pressure egr system with condensate management

An exhaust gas recirculation (EGR) system for use in an internal combustion (IC) engine system, where the IC engine system comprises an air intake system and an exhaust system, the EGR system comprising:

• a condensation ejection system in fluid communication with a condensate drain configured to drain exhaust liquid from a cooler, the condensation ejection system comprising a nozzle configured to assist in the draining of the exhaust liquid from the condensate drain using pressurized air, wherein:
• the nozzle is in fluid communication with a compressor associated with the intake system and a brake system of a vehicle powered by the IC engine system;
• and
• the pressurized air is configured to be delivered to the nozzle by one of the compressor or the brake system.

A method of circulating engine exhaust gas from an exhaust system of internal combustion (IC) engine to an intake system of the IC engine, comprising:

• cooling exhaust gas from the exhaust system with a first cooler using a coolant fluid;
• mixing the exhaust gas cooled by the first cooler with intake air from the intake system in a mixture chamber to form an exhaust-air mixture;
• cooling the exhaust-air mixture in a second cooler using the coolant fluid;
• circulating and cooling the coolant fluid using a heat exchange system, wherein the heat exchange system comprises a coolant temperature sensor configured to take temperature readings of the coolant fluid;
• calculating, by a controller, a determined property of the exhaust-air mixture based on readings from a sensor assembly configured to gather readings of properties of the exhaust-air mixture;
• and
• controlling, by the controller, the heat exchange system to adjust an attribute of the coolant fluid supplied to at least one of the first cooler or the second cooler based at least partially on the determined property.
