摘要： A switchable exhaust gas heat exchanger includes an exhaust gas feed line and an exhaust gas discharge for an exhaust gas stream; a first exhaust gas passage and a second exhaust gas passage; a switching valve configured to switch the exhaust gas stream between the first and second exhaust gas passages; and a heat exchanger through which a coolant flows which is arranged in the first exhaust gas passage. The second exhaust gas passage routes the exhaust gas stream past the heat exchanger to the exhaust gas discharge. The switching valve is configured to be switched as a function of the temperature of the coolant and is a proportional control valve. A switching threshold and a switching limit of the coolant determine flow of the exhaust gas stream through the first and second exhaust gas passages.

摘要： A control apparatus/method curbs the degradation of emission gas, for a vehicular driving apparatus including an engine and a second driving power source that assists the engine in the output of driving power. Torque assist is executed by a hybrid controller through the use of a first motor-generator and/or the second motor-generator so that the EGR rate achieved by an EGR device becomes greater than or equal to an EGR rate threshold value (first EGR rate) determined on the basis of the load state of an engine. Therefore, it becomes possible to put the engine in a low load state where the EGR rate, which decreases as the engine shifts to higher load states, is greater than or equal to the EGR rate threshold value.

摘要： A method for rapidly heating an emission control device in an engine exhaust uses excess air added to the exhaust via an air introduction device. After an engine cold start, the engine is operated to raise exhaust manifold temperature to a first predetermined value by operating the engine with a lean air-fuel ratio and retarded ignition timing. Once the exhaust manifold reaches the predetermined temperature value, the engine is switched to operate rich and air is added via the air introduction device. The added air and rich exhaust gas burn in the exhaust, thereby generating heat and raising catalyst temperature even more rapidly. The rich operation and excess air are continued until either engine airflow increases beyond a pre-selected value, or the emission control device reaches a desired temperature value. After the emission control device reaches the desired temperature, the engine is operated substantially around stoichiometry. Further, a method is described for adaptively learning pump airflow using feedback from an exhaust gas oxygen sensor.

摘要： Under a partial load, a pumping loss is reduced by a stratified combustion to enhance a fuel consumption, and during the maximum output operation, the output is increased by a premixture combustion, and the output of an engine is controlled, thereby enhancing the drivability. Under the partial load, an ignition source is provided in the vicinity of a fuel injection valve, and after the fuel is injected, the mixture is ignited, and a resulting flame is caused by a spray of the fuel to spread into a cylinder, thereby effecting a stratified combustion. When the load increases, so that soot and so on are produced in the stratified combustion, the fuel injection is effected a plurality of times in a divided manner, and a premixture is produced within the cylinder by the front-half injection, and a flame, produced by the latter-half injection, is injected into the cylinder to burn this premixture.
