An exhaust gas conduction system for a gasoline engine comprises an exhaust gas line and an intake line which can be connected to an intake manifold, a charge air compressor arranged in the intake line, and a turbine arranged in the exhaust gas line. The exhaust gas line has at least one bypass line with a bypass throttle valve. At least one exhaust gas recirculation line with an EGR throttle valve is provided. At least one particle filter is arranged in the bypass line and an exhaust gas valve is provided in the exhaust gas line.

The disclosure relates to a gasoline engine comprising an exhaust gas line which can be connected to an exhaust manifold of the gasoline engine, an intake line which can be connected to an intake manifold of the gasoline engine, a charge air compressor which is arranged in the intake line, and a turbine which is arranged in the exhaust gas line. The exhaust gas line has at least one bypass line with a bypass throttle valve, said line branching off from the exhaust gas line at a branch upstream of the turbine and branching back into the exhaust gas line at an opening downstream of the turbine. At least one exhaust gas recirculation line with an EGR throttle valve is provided, said line branching off from the exhaust gas line at a branch and opening into the intake line at an opening, wherein a coupling line with a first node point and a second node point is provided, the bypass line and the EGR line being combined in some sections in said coupling line; at least one particle filter is arranged in the coupling line; and the first node point is arranged downstream of the branch and downstream of the branch.

An exhaust aftertreatment system may include a reductant tank, a gaseous ammonia source, an injector, first conduit and a second conduit. The injector may receive the liquid reductant from the reductant tank and the gaseous ammonia from the gaseous ammonia source and inject the liquid reductant into a stream of exhaust gas in a first mode, inject the gaseous ammonia into the stream of exhaust gas in a second mode, and both the liquid reductant and the gaseous ammonia into the stream of exhaust gas in a third mode. The first conduit may communicate liquid reductant from the reductant tank to the injector. The second conduit may communicate gaseous ammonia from the gaseous ammonia source to the injector.
