摘要： A four-valve per cylinder engine has two intake valves, two exhaust valves and a centrally located fuel injector. Between each adjacent pair of valves is a valve bridge with a point of minimum separation between adjacent valves. In the present disclosure, the glow plug port is defined in the cylinder top at a location outboard of the minimum separation between adjacent and at a depth which is tangent to an edge of a fuel jet emanating the injector. By placing the glow plug farther outboard than found in the prior art, the glow plug contacts the fuel as it comes out of the injector and as it rebounds off a feature of the piston bowl.

摘要： Methods and systems are provided for operating an engine including an emission control system, the emission control system comprising a catalyst downstream of a turbine of a boosting device and a reductant injector upstream of the turbine. In one example, the method comprises injecting reductant into exhaust upstream of the turbine, mixing the injected reductant with exhaust gas via the turbine, and delivering the mixed reductant to the catalyst.

摘要： Methods and systems are provided for controlling an engine in a vehicle, the engine having a turbocharger, and a particulate filter upstream of a turbocharger turbine. In one example, the method comprises, under selected boosted operating conditions, injecting a reductant upstream of the filter during an exhaust stroke to generate an exothermic reaction at the filter.
