    en.wikipedia.org/wiki/Ford_Sigma_engine

    The Ford Sigma is a small straight four automobile engine introduced in 1995 by Ford Motor Company. Its first evolution was sold as the Zetec-S (not to be confused with the trim level), then Zetec-SE and finally, in later years, renamed Duratec . [ 3 ]

    Ford's internal code name for the TLCS-12 microprocessor was "PM-11" or "Poor Man's 11" implying it was a stripped down version of the, then popular, Digital Equipment Corporation PDP-11 computer. A PDP-11 was used in a vehicle in the first half of the 1970s for "proof of concept".

  5. Variable compression ratio - Wikipedia

    en.wikipedia.org/wiki/Variable_compression_ratio

    It was installed in their QX50 SUV. The engine can produce any compression ratio from 8:1 to 14:1. The highest torque is achieved at 8:1, giving high acceleration, while the best gas mileage (fuel efficiency) is achieved at 14:1. The electronic engine controller responds to the pressure on the gas pedal, in real-time, altering the compression ...

    en.wikipedia.org/wiki/NOx_adsorber

    A NO x adsorber is designed to reduce oxides of nitrogen emitted in the exhaust gas of a lean burn internal combustion engine.Lean burn engines, particularly diesels, present a special challenge to emission control system designers because of the relatively high levels of O 2 (atmospheric oxygen) in the exhaust gas.

    The Proterra Catalyst was an evolution of the EcoRide, initially available as a standard 40-foot (12 m) transit bus length in 2014 with the same fast-charging battery as the EcoRide and a similar composite chassis. [27] A 35-foot (11 m) Catalyst was introduced in 2015 to directly replace the earlier EcoRide.

    The hole density may be from 30 to 200 per cm 2, and the separating walls can be 0.05 to 0.3 mm. The many small holes have a much larger surface area than one large hole. High surface area facilitates catalytic reaction or filtration.

  9. Catalytic heater - Wikipedia

    en.wikipedia.org/wiki/Catalytic_heater

    A catalytic heater is a flameless heater which relies on catalyzed chemical reactions to break down molecules and produce calefaction (heat). [1] When the catalyst, fuel (e.g., natural gas), and oxygen combine together, they react at a low enough temperature that a flame is not produced.
