  • Publication number: 20160281573
    Abstract: An internal combustion engine is provided with a hydrocarbon feed valve arranged in an engine exhaust passage. When injection control for injecting hydrocarbons from the hydrocarbon feed valve for exhaust treatment is stopped, to prevent the hydrocarbon feed valve from clogging, hydrocarbons for preventing clogging are injected from the hydrocarbon feed valve when the engine is not discharging soot, that is, when the feed of fuel to the inside of the combustion chamber is stopped and, after hydrocarbons for preventing clogging are injected once, the injection of hydrocarbons for preventing clogging from the hydrocarbon feed valve is stopped until injection control for exhaust treatment is started.

    Abstract: The described reduction gearbox of a gas turbine engine includes a first gear reduction stage having an input gear adapted to be driven by a turbine output shaft. The input gear transfers power received from the turbine output shaft laterally away from the input gear to an input speed gear. Each input speed gear engages an output speed gear to define a main speed reduction gear set, and the main speed reduction gear sets are laterally spaced apart from one another to define a gap. The gearbox has a second gear reduction stage driven by the output speed gears, the second stage adapted to drive an engine output shaft.

  • Publication number: 20160281614
    Abstract: An internal combustion engine with an adjustable compression ratio has connecting rods (1), each of which has a hydraulically adjustable eccentric adjustment device arranged in a connecting rod bearing eye (2) and/or in a crankpin bearing eye (3) for adjusting an effective connecting rod length (leff) of the respective connecting rod (1). Travel of the eccentric adjustment device is controlled by a switchover valve (10). Each switchover valve (10) has a pick-off means (14). The switchover valves (10) can be actuated by an actuation device (15) that has a switching fork (16) for each switchover valve (10) and thus for each pick-off means (14) to be actuated. The pick-off means (14) and the switching forks (16) are oriented relative to one another so that inertial forces acting during driving assist the actuation of the switchover valves (10) by the actuation device (15).

  • Publication number: 20160281619
    Abstract: A system and method are disclosed for desulfating an oxidation catalyst in an aftertreatment system of a multifuel internal combustion engine. The oxidation catalyst can be desulfated in response to one or more desulfation triggering events. The desulfation process includes providing hydrocarbons from one or all of the multiple fuel sources to an upstream oxidation catalyst. The hydrocarbons react with the exhaust gas within the upstream oxidation catalyst to deplete oxygen in the exhaust flow to thereby reduce the desulfation temperature of the oxidation catalyst while elevating a temperature of the exhaust gas to a desulfation temperature range.
