An internal combustion engine has a water-cooled intercooler cooling intake air turbocharged by a turbocharger. The intercooler has an HT intercooler into which HT cooling water passing through a cylinder block is introduced and an LT intercooler into which LT cooling water lower in temperature…
An exhaust gas recirculation system includes a turbo charger having a compressor wheel and a turbine wheel, a high-pressure intake passage provided between the compressor wheel and an intake port of an internal combustion engine, a charge air cooler provided on the high-pressure intake passage to…
An object of the present invention is to provide an EGR gas cooling system which can rapidly raise the temperature of cooling water after an engine is stated. The EGR gas cooling system of the present invention includes a main cooling water circuit (6)which circulates cooling water between an…
In an anti-freezing device for an EGR device 14 with an EGR cooler 12 being provided midway of an EGR pipe 11 for extraction and recirculation of a part of exhaust gas from an exhaust side to an intake side, a downstream EGR pipe 11b downstream of the EGR cooler 12 being connected through a flange…
A charge air guide element (23) and a water ring element (40) for an internal combustion engine are configured to supply cooling water to the water ring element (40) via the charge air guide element (23). Specifically, a cooling water channel system (50A, 50B) may be integrated into a wall…
The system has a distributor (102) dividing a coolant flow into a first coolant flow for cooling an indirect intercooler (104) for an engine (114) i.e. internal combustion engine, of a vehicle, and a second coolant flow for cooling an indirect condenser (106) of an air conditioning apparatus of the…
The cooling system has a charge-air cooling unit (140) for a motor assembly and a capacitor unit (170) for an air conditioner. Units are formed for supplying a coolant flow to the charge-air cooling unit and to the condenser unit, which are connected to a common coolant circuit. The coolant flow is…
A multifunctional module for internal combustion engine, forming a structural assembly and incorporating the functions of exhaust gas cooling and regulation, at least in part, of the circulation flows in said engine's cooling circuit, comprising a first functional unit incorporating, on the one…
An engine cooling system controls a cooling degree of an engine 1 according to an operating condition thereof by circulating cooling water through the engine. This system is provided with a water temperature sensor 31 for detecting a cooling water temperature THW1, a flow rate regulating valve 8…
The method involves feeding the waste heat from the engine (16) to the cabin (21) of the vehicle. The temperature of the engine is measured directly or indirectly and if the temperature is less than a first threshold the air feed to the engine is choked to set a defined reduced induction pressure…
The coolant circuit (1) downstream of the coolant pump is divided into an engine cooling circuit (I) through the engine (2), crankcase and cylinder head and an exhaust circuit (II) with exhaust manifold (3) and turbocharger (4) and also a heat exchange circuit (III) with heat exchangers (9 and 8)…
