A system and method for discharging condensation from an engine system is disclosed. The system includes a drainage pathway from an upstream body that collects water to a downstream portion of the air intake system. A controller may initiate a draining event upon determining a threshold amount of water has been collected in the upstream body.

The invention relates to a charge air cooler (5) for fuel engine comprising: a casing having an inlet (16) and an outlet (20), a heat exchanger (10) within the casing between the inlet (16) and the outlet (20), a thermally responsive draining mechanism (50, 60) for draining condensates, the draining mechanism (50, 60) being configured to drain condensates when temperature within the charge air cooler (5) is below a defined temperature, draining mechanism comprising a drain port (58, 68), a valve (51, 61, 52, 62, 53, 63) arranged on the drain port (58, 68), an actuation device (53, 63, 64) for moving the valve between an opened state and a closed state,
wherein the actuation device includes a phase change material.

An apparatus for removing condensed water of an intercooler includes a collecting portion for collecting condensed water, the collecting portion being provided at a lower end of the intercooler; and an ultrasonic wave vibrator provided in the collecting portion, the ultrasonic wave vibrator being operated to introduce the condensed water collected in the collecting portion toward an engine so that the condensed water is vaporized, thereby removing or significantly reducing an amount of condensed water in the intercooler. The apparatus for removing condensed water of the intercooler can prevent engine damage and ignition failure due to the presence of the condensed water in the intercooler.

A system and method for removing condensate water of an intercooler for a hybrid vehicle are configured to improve combustion efficiency of an engine by supercharging intake air to a combustion chamber of the engine using an electronic compressor instead of an existing turbocharger and configured to backward drive the electronic compressor to distribute and capture the condensate water generated in the intercooler, especially, when the engine is turned off.

An intake device for an internal combustion engine includes: a main pipe having an upstream end forming a suction port and a downstream end configured to be connected to an intake port of an internal combustion engine main body; a compressor of a supercharger provided in the main pipe; an intercooler provided in the main pipe at a position downstream of the compressor and including a cooling part, an upstream header provided upstream of the cooling part, and a downstream header provided downstream of the cooling part; a throttle valve disposed in the main pipe at a position downstream of the intercooler; a bypass pipe having a first end and a second end, the bypass pipe being connected to a part of the main pipe between the cooling part and the throttle valve; and a catch tank provided in the bypass pipe and configure to catch condensed water.

An engine system includes a charge-air cooler, a separator for separating water from an airflow, and an engine. The separator causes an airflow from the charge-air cooler to strike one or more partitions and change directions via a serpentine path such that water is separated out of the airflow before the airflow reaches the engine.

Disclosed are two system devices for stratified injecting the recirculated exhaust gas and high-specific-heat-capacity or inert gas for clean combustion of an internal combustion engine. The former is composed of an exhaust gas recirculation system, an injection system, and a power system. The latter is composed of four parts, and a high-specific-heat-capacity gas or inert gas channel is added. Injectors can be arranged at any position in the cylinder between a top dead center and a bottom dead center of a piston in a cylinder; 1-3 layers of injectors can be arranged; and 2-6 injectors can be arranged on each layer. Gas participating in combustion enters the cylinder from two intake channels, namely, a scavenging port of the internal combustion engine and the injectors; an in-cylinder swirl ratio can be remarkably increased through kinetic energy carried by the gas; and fuel-gas mixing is promoted, and the combustion rate is increased.

An air cooling system for a vehicle engine includes an air intake configured to receive intake air for delivery to the engine, a first coolant loop thermally coupled to the air intake to provide cooling to the intake air, and a pump for circulating coolant through the first coolant loop. A second coolant loop is thermally coupled to the air intake to provide further cooling to the intake air, and undergoes a vapor compression cycle. A compressor circulates coolant through the second coolant loop. The first and second coolant loops are separate loops using a common condenser. A passive variable charge enabler assembly is configured to remove coolant circulating in the system when the compressor is on.
