Multilayer ceramic NOx gas sensor device
InactiveUS20070012566A1Improve performanceFaster sensor light off timeWeather/light/corrosion resistanceVolume/mass flow measurementMiniaturizationExhaust gas emissions
A mixed potential NOx sensor apparatus for measuring the total NOx concentration in a gas stream is disclosed. The NOx sensing apparatus comprises a multilayer ceramic structure with electrodes for sensing both oxygen and NOx gas concentrations and includes screen-printed metallized patterns that function to heat the ceramic sensing element to the proper temperature for optimum performance. This design may provide advantages over the existing technology by miniaturizing the sensing element to provide potentially faster sensor light off times and thereby reduce undesired exhaust gas emissions. By incorporating the heating source within the ceramic sensing structure, the time to reach the temperature of operation is shortened, and thermal gradients and stresses are minimized. These improvements may provide increased sensor performance, reliability, and lifetime.

Rapid catalyst warm-up control device for internal combustion engine
InactiveUS20040250534A1Efficient mixingReduce gas emissionsElectrical controlInternal combustion piston enginesExternal combustion engineEngineering
A rapid catalyst warm-up control device for an internal combustion engine performs irregular injection dither control during the rapid catalyst warm-up control after starting the engine. In the irregular injection dither control, injection modes are switched after every fuel injection to the cylinders (every 180° CA for a 4-cylinder engine) between a lean injection mode and a rich injection mode in such a pattern that rich injections will not occur consecutively for the same cylinder (dither cycle=540° CA, 900° CA, 1080° CA, or the like). In the lean injection mode, fuel is injected such that the air-fuel ratio is leaner than the stoichiometric ratio, and in the rich injection mode, air-fuel ratio is richer than the stoichiometric ratio. The rich gas emitted from the cylinders where the rich injection has been performed is thus allowed to flow through a different catalyst region every time instead of flowing only through the same region.

Selective Compound Engine
InactiveUS20090301086A1Improve fuel efficiencyReduce cylinder compression ratioCombustion enginesHot gas positive displacement engine plantsExhaust valveFuel efficiency
The fuel efficiency of an internal combustion reciprocating piston engine may be increased through selective secondary expansion of exhaust gas in the engine cylinders in order to recover exhaust gas energy which is otherwise wasted by cylinder blow-down at the end of the power stroke. Exhaust valve cam switching, intake valve deactivation, multiple exhaust valves, a specialized exhaust manifold arrangement and an exhaust gas diverter valve can be configured to enable a reciprocating engine to selectively operate in efficient eight stroke cycle compound mode when moderate engine power is demanded, then revert to conventional four stroke cycle non-compound mode operation when high engine power is demanded, without stopping the engine. For a road vehicle application, the benefit is substantially reduced highway cruising fuel consumption, while incurring minimal impact on engine weight, minimal impact on engine manufacturing cost, and no adverse impact on vehicle acceleration performance, hill climbing performance or trailer towing performance.
